How long does it take for tomatoes from sowing to fruiting?

Question 1: How long does it take for tomatoes to be harvested from sowing? It usually takes more than one month to raise seedlings. It takes about 10 days after transplanting, and it takes about 40~50 days for the fruit to begin to mature. The picking period of open-air cultivation is about one month to one and a half months, that of limited-length cultivation in greenhouse is about one month, and that of infinite-length cultivation varies from six months to three years according to different cultivation methods.

Question 2: How many days and three months does it take for tomatoes to grow and harvest?

2. Birth cycle

Tomato is a perennial herb in tropical regions, but it is cultivated as 1 year in frost regions in temperate regions. Its growth and development process has certain stages and periodicity, which can be roughly divided into four different stages: germination stage, seedling stage, flowering stage and fruiting stage.

Germination period of tomato photography: from sowing to the appearance of the first real leaf (heartbreak). At room temperature, this period is 7 ~ 9 days; The germination period is from seed water absorption to cotyledon unfolding to expose true leaves. At room temperature, it usually takes 10- 14 days from sowing to true leaf heart breaking. If the temperature is too low, seedling emergence will be slow. The process from germination to cotyledon development belongs to heterotrophic growth, and the nutrients needed for its growth are supplied by the seeds themselves, that is, from germination to seedling stage.

Seedling stage: refers to the period from the appearance of the first true leaf to the appearance of the first inflorescence. The suitable daytime temperature is 25 ~ 28℃, and the nighttime temperature is 13 ~ 17℃. The ground temperature in this period has great influence on seedling growth, and the suitable ground temperature should be kept at 22 ~ 23℃. The first flowering and fruit-setting period refers to the period from the first inflorescence to fruit-setting. This stage is the turning point of tomato from vegetative growth to reproductive growth and vegetative growth, which is directly related to the formation and yield of product organs;

Tomato flowering period: It takes about 1 5-30 days from the time when the inflorescence sprouts to the time when it bears fruit. During this period, the plant not only continued to differentiate and develop flower buds and leaf buds, but also grew vigorously in nutrition, and the phenomenon of plant height increase and leaf growth appeared. Therefore, at this stage, it is necessary to adjust the relationship between vegetative growth and reproductive growth, not only to make vegetative growth full, leaves stout, stems stout and deep-rooted, but also to avoid virtual growth, prevent flowering and delay flowering and fruiting.

Fruiting period: from the first inflorescence to the end of harvesting (seedling pulling). In this period, fruits and seedlings grow at the same time, so it is a key task to solve the contradiction between vegetative growth and reproductive growth.

3. Fruit ripening process

The fruit ripening process can be divided into the following five stages according to the external morphology, and it should be harvested in time according to the needs in production.

(1) In the green ripening stage (white ripening stage), the fruit does not increase, the peel is shiny, and the color of the fruit turns from green to white. Green and ripe fruits can be artificially ripened or harvested and stored.

(2) During the color acceleration period (color change period), most fruits were white and green, but the top of the fruits turned red. The fruit with accelerated color is hard, suitable for long-distance transportation and of good quality. During this period, the seeds are basically mature.

(3) Except the fruit shoulder, the fruit turns red from a few to all at maturity. Mature fruit has shown the inherent color of the variety, but it has not yet softened, and has high nutritional value. It is best to eat it raw and should be harvested in time. At this point, the seeds in the fruit are fully mature.

(4) At the mature stage, all the fruits turn red, the pulp becomes soft, the sugar content increases, the sweetness increases, and the seeds mature and full.

(5) The over-ripe fruit is severely softened, and the pulp is soaked in water, so it is no longer suitable for sale as a fresh food commodity.

The fruit-bearing period is characterized by the synchronous growth of seedlings and fruits, and the contradiction between vegetative growth and reproductive growth always exists. Regulating the relationship between seedlings and fruits is the key technology in production. [5]

4. Requirements for environmental conditions

(1) Temperature: Tomato is a warm vegetable. Under normal circumstances, the optimum temperature for assimilation is 20 ~ 25℃, and the optimum soil temperature for root growth is 20 ~ 22℃. Increasing soil temperature can not only promote root development, but also significantly increase the content of nitrate nitrogen in soil, accelerate growth and improve yield.

(2) Illumination: Tomato is a light-loving crop with a light saturation point of 70000lx, and the suitable light intensity for tomato is 30,000 ~ 50,000 lx. Tomato is a short-day plant. In the process of changing from vegetative growth to reproductive growth, short-day is basically needed, but the requirements are not strict. Some varieties can germinate and blossom in advance under short sunshine, while most varieties bloom earlier under 1 1 ~ 13h sunshine, and the plants grow healthily.

(3) Moisture: Tomatoes need more water, but they don't need regular irrigation. Generally, the soil humidity is 60-80% and the air humidity is 45-50%. High air humidity not only hinders normal pollination, but also causes serious diseases under high temperature and high humidity conditions.

(4) Soil and nutrition: Tomatoes do not require high soil conditions, but in order to obtain high yield and promote good root development, tomatoes need to absorb a lot of nutrients from the soil during their growth. According to Eigerstein, for every 5,000 kilograms of fruit, they need to absorb 33 kilograms of potassium oxide, 10 kilograms of nitrogen and 5 kilograms of phosphoric acid from the soil. ...& gt& gt

Question 3: It takes about 90 days to sow tomatoes, about 70 days to pick edible seedlings, and only about 10 days for tomatoes to bear fruit.

Question 4: How long does it take to transplant tomatoes? Generally tomato seedlings can be transplanted in 90 days. The specific time depends on the degree of seedling development.

The process of tomato seedling raising:

1. Seedling raising time: Seeding and seedling raising are generally carried out from the end of February to the beginning of 10.

2. Seed disinfection: Generally, the dosage of seeds per mu is 30-50g. Sun the seeds for two days before sowing to improve the germination rate. Blanch the seeds with warm water at 55℃ 15 minutes, keep the temperature and stir in one direction, then add cold water to cool down to 35℃ and soak the seeds for 6-8 hours. In order to prevent the occurrence of viral diseases, it can be soaked in 10% trisodium phosphate solution for 40 ~ 50 minutes, then the seed coat mucus is washed with clear water, drained, dried and sown.

3. Establish seedbed: per mu seedbed 10, fully decomposed organic fertilizer 100 kg, Zhuang Yong fertilizer 500 g, 3 100 g, evenly spread and shallow turn 12 cm, level the seedbed and water it. Use Su Zhining (58% nail cream? Manganese and zinc) or Hi Duosheng (70% propineb) and 70% Xingnong Lu Zheng (thiophanate-methyl) 1: 1, evenly mixing the medicine per square meter 10g and 5kg of sieved fine soil, leveling the seedbed with 2/3 nutrient soil during sowing to make bedding soil, and sowing evenly after sowing. In order to promote early emergence, the seedbed should be covered with plastic film, and the temperature should be kept at about 30℃ during the day, with a maximum of 32℃. When 65,438+0/3 seedlings are unearthed, the plastic film should be removed, and the seedlings should be leveled and cooled to about 25℃ to prevent excessive growth. After emergence, use Ipoh (68.75% oxazolidinone. 10g of manganese and zinc) or 30g of Xiduosheng (70% propineb) and 20ml of free dew (72.2% propamocarb hydrochloride) are repeatedly sprayed with15kg of water to prevent and control seedling damping-off, damping-off and early blight.

4. Seedling division: When the seedlings grow to two leaves and one heart, it is the key period for seedling division. Prepare nutrient soil in advance, and prepare nutrient soil 1 m3 with 60% of field topsoil (remove 5cm topsoil to avoid herbicide residue), 40% of decomposed organic fertilizer,10kg of haizhuangyuan biological bacterial fertilizer, 90g of Xiduosheng (70% propineb) and 500g of Zhuang Yong, and put them into a bowl. Dip the roots of tomato seedlings with 1000 times sea elf before seedling separation. The temperature is controlled at 28℃ ~ 30℃ within 3 days after seedling separation, and at 22℃ ~ 25℃ after seedling delay. Pay attention to spraying 1 750 times liquid-free dew (72.2% propamocarb hydrochloride) before seedling division to prevent damping off, and irrigating roots with 500 times Zhuang Yong solution and 500 times premium root solution to prevent damping off, and at the same time, tomato seedlings will take more roots.

5. Promote flower bud differentiation: The flower bud differentiation of tomato starts from the third true leaf, ends at the ninth true leaf, and basically reaches the seventh true leaf. At this time, the first three ears of fruit have been differentiated. If the flower bud differentiation is not good, deformed flowers and deformed fruits will appear in the later stage, so the quality of flower bud differentiation at seedling stage directly determines the early yield. In order to promote flower bud differentiation, spraying 25 grams of Huaguoduo and 8 grams of sea elf on 3 ~ 5 real leaves can promote flower bud differentiation.

6. Diseases and pests at seedling stage: mainly control whitefly, aphid and liriomyza sativae, spray 5 g of 70% imidacloprid with 15 kg of water and 40% wanling 10 g. The main diseases at seedling stage are virus disease and stem rot. To prevent viral diseases, 4% ningnanmycin 25ml+ CommScope Zinc 4ml+ Longdeng Youduo Boron 15ml+ Haijing 8g+ honey 100ml, and water spraying15kg should be used. The control of stem rot can be done by yikuaijing (52.5% oxazolidinone? Cymoxanil) 9g+ Koside 3000 10g+ Sea Elf 8g+ 15kg spray seedbed is water.

7. Standard for planting seedlings: the seedling age is about 90 days, the main stem is half purple and half green, 70% has buds, the stem is 0.6 cm thick, and the root system is developed without pests and diseases.

Question 5: How many days does it take to grow tomatoes? There are two types, one is annual and the other is infinite growth.

Annual plants generally grow for 4 to 6 months, and if the environmental conditions are better, the growth period will be longer.

Another kind of tomato is infinite growth type, which can grow for many years and keep growing and bearing fruit.

Question 6: How long does it take for tomatoes to be harvested? Panicum miliaceum can complete its life cycle in one growing season, that is, the hydroponic tomatoes that died after flowering and fruiting in the greenhouse are planted in early July each year, and the cultivation tubes are planted in mid-August: the water and fertilizer of tomatoes are automatically controlled 8 times a day for about 8 minutes each time, and the harvesting period is from mid-October to early July of the following year.

Question 7: How long does it take from a seed to a tomato? It usually takes two months. It takes about 1 month to grow seedlings in March and blossom and bear fruit in May. I just started eating a few days ago. When you raise seedlings at this time, the temperature is too high, and it is difficult to determine how to grow. If the temperature is too high, it is difficult to bear fruit, and you don't know when to eat. It depends on the weather.

Question 8: How long does it take for small tomatoes (cherry tomatoes) to bear fruit? It takes about 90 days to sow, pick and eat.

If seedlings are used, they can be picked and eaten in about 70 days.

Deduct 10 days as long as the result is obtained.

Question 9: How many days does it take to sow tomatoes and pick fruits?

Growth and development cycle of tomato

The period from seed sowing and germination to the maturity of the first ear seed is the growth and development cycle. It is divided into four stages: germination stage, seedling stage, flowering and fruiting stage and fruiting stage.

First, the budding period

The development period is from seed germination to two cotyledons growing the first true leaf, usually 7-9 days.

Second, the seedling stage

The period from the first true leaf to the big bud is the seedling stage, which generally takes about 50 days at suitable temperature, 60-80 days in cold season and 40 days in high temperature season.

Third, the flowering and fruit-setting period

This period needs 15-30 days, and the early or high temperature growth time is short, otherwise it is long.

Four. Fruiting period

The fruiting period is from the first inflorescence to the completion of all fruits, with 70-80 days in spring and July-August in solar greenhouse. The fruiting period of tomatoes is the time when nutrients and water are most needed, and it is also an important period of management.
