What month were carrots planted?

Question 1: It is suitable to grow carrots and carrots in wet, deep and well-drained soil. Sowing is usually carried out from late August to mid-September, and the harvest period is11-65438+February. When sowing, water or manure should be poured first, and then soil should be sown, so that the seedlings will have greater capacity. When sowing, seed is first dressed with new high-fat film, and then 5-7 seeds are sown in each nest. After sowing, the thickness of covering soil is about 2 cm, not too thick. At the same time, spraying 800 times solution of new high-fat film can keep moisture and prevent evaporation, prevent sun and drought, keep warm and prevent freezing, prevent soil hardening, suffocate and isolate pests and diseases, and improve the emergence rate. When carrots emerge, they should be spaced in time (that is, even seedlings) to avoid crowding each other or poor lighting, but we must master the principle of spacing seedlings early and fixing seedlings later. When the average number of plants is 1-2 leaves, it can be planted evenly once, leaving 3 plants in each nest; When there are 3-4 leaves, the seedlings are evenly distributed for the second time; 5-6 leaves grow into seedlings, leaving 1 plant in each nest. Spraying new high-fat film after transplanting seedlings can effectively prevent water evaporation and diseases and pests on the ground, shorten the slow seedling stage, quickly adapt to the new environment and grow healthily.

Question 2: When do you plant carrots? The best time to sow carrots is between midsummer and hot summer, but in recent years, carrots have also appeared in spring due to market demand. Spring sowing is earlier, and it should be from late February to early March (sowing in early spring in February and harvesting in summer in June) and summer stubble (sowing in July and August, 165438+ 10).

Question 3: When planting carrots, the best time to sow carrots is between small summer and big summer, but in recent years, carrots have also appeared in spring due to market demand.

Spring sowing is earlier and should be carried out from late February to early March.

First, choose varieties.

Spring-sown carrots are very strict in variety selection. We must choose middle and early maturing varieties with late bolting, strong heat resistance, good varieties and short growth period, such as Anh Hong No.2, Hongxiu, 7585 and Improved Wucun.

Second, determine the sowing date

In Hualong Town, Shouguang City, Shandong Province, Heguan Town, Qingzhou City and their surrounding carrot planting areas, carrots are usually harvested twice a year, namely in spring (sowing in February in early spring and harvesting in June in summer) and summer (sowing in July and August,165438+1October). Most vegetable farmers usually choose beginning of spring as the planting time, that is, at the beginning of February every year, local vegetable farmers use small arch sheds to raise the ground temperature. In fact, according to the data, the lowest temperature of carrot germination is 7℃, and the sowing period of spring carrots in most northern areas is generally from mid-late March to early April. Sowing too early is easy to bolt ahead of time, sowing too late is easy to be damaged by storms in the later growth period.

Third, select plots and prepare soil.

Carrots like soil or loam with deep soil layer, loose soil, good drainage and rich organic matter. As long as they are properly cultivated in some clayey soil, they can get high yield. In spring, carrots must be planted in plots with high terrain and convenient irrigation and drainage. For clay land, smooth drainage is one of the important factors that determine the success of cultivation, especially for varieties with tender meat and low cellulose content. Because the fleshy roots of carrots are deep in the soil, if cultivated too shallow, the soil is not loose enough, and the fleshy roots are easy to bend, shorten or even diverge. Therefore, it is required to deepen the soil and apply base fertilizer, preferably decomposed organic fertilizer (if fresh manure is used, it is easy to fork roots), and apply 5-6 cubic meters of organic fertilizer per mu. If there is no organic fertilizer, you can also apply 50 kilograms of compound fertilizer and a small amount of urea and potassium dihydrogen phosphate per mu, then plough deeply for 25-30 cm, and then break the clods into ridges with a width of 1.0-65438. The topsoil on the ridge surface must be fine and flat to facilitate orderly sowing and germination.

Fourth, fine sowing.

First of all, we should pay attention to the quality and germination rate of seeds. If necessary, the germination test should be carried out first to ensure the appropriate sowing amount. When sowing in spring, it is best to soak the seeds first to facilitate the emergence of seedlings. When the weather is dry, it is best to wet the soil and loosen it before sowing.

Verb (abbreviation of verb) sowing method

1. Seed soaking: Before sowing 1 day in the afternoon, soak the seeds in warm water at 37℃ 12 ~ 16 hours, take them out to dry, mix dry sand and sow. In order to spread the seeds evenly, you can add more sand appropriately.

2, sowing: sowing, drilling can be. The covering thickness is about1.5cm.. After sowing, rake with a rake for 2 ~ 3 times to make the surface smooth, and the floating soil above the seeds should be finely divided. After sowing, pat the surface of the border with a shovel back to make the seeds closely combine with the soil.

3. Spraying herbicides: Generally, carrots emerge slowly. After seed soaking, it takes about 10 days from sowing to emergence. Generally, weeds are unearthed before seedlings, which leads to overgrowth of weeds. Therefore, it is best to spray 200ml herbicide and 50kg water on the border on the day of sowing or the next day, and the control rate of most weeds can reach 80%.

4. Watering: After sowing, if it doesn't rain, you must water along the ditch on the day of sowing, otherwise it will affect the emergence rate. When watering, water should seep from bottom to top to keep the soil surface moist, and it can also prevent the soil from hardening due to rain, which makes seedling emergence difficult. If the outside temperature is suitable, the plastic film or small arch shed can be removed 9 days after sowing (before the carrot seedlings are unearthed), or the carrot seedlings can be properly aired and exercised after being unearthed, and the film can be removed in time.

Question 4: When planting carrots, the best time to sow carrots is between small summer and big summer, but in recent years, carrots have also appeared in spring due to market demand.

Spring sowing is earlier and should be carried out from late February to early March. It is inappropriate for you to sow now! But if you can choose a well-drained plot, you can also choose one!

First, choose varieties.

Spring-sown carrots are very strict in variety selection. We must choose middle and early maturing varieties with late bolting, strong heat resistance, good varieties and short growth period, such as Anh Hong No.2, Hongxiu, 7585 and Improved Wucun.

Most vegetable farmers usually choose beginning of spring as the planting time, that is, at the beginning of February every year, local vegetable farmers use small arch sheds to raise the ground temperature. In fact, according to the data, the lowest temperature of carrot germination is 7℃. In the northern part of our province and most parts of the north, the sowing period of spring carrots in the open field is generally from the middle and late March to the early April. Sowing too early is easy to bolt ahead of time, sowing too late is easy to be damaged by storms in the later growth period.

Question 5: In what month do you plant radishes and radishes?

The first of the three hottest ten-day periods in summer

20 14.7. 18 - 20 14.7.28

Question 6: After planting carrots for a few days, you can come out. Spread carrots and cover them with soil to suppress them. After 7 ~ 10 days, it can be feathered.

Planting method of carrot:

1. Suitable temperature for planting carrots:

Carrots are semi-cold-tolerant vegetables. The suitable temperature for germination is 20-25 degrees Celsius, and the suitable temperature for growth is 18-23 degrees Celsius during the day and 13- 18 degrees Celsius at night. Too high or too low temperature is not conducive to growth. Carrot root system is developed, so deep tillage plays an important role in promoting vigorous root growth and fleshy root hypertrophy.

2, carrot planting soil requirements:

The soil should be deep sandy loam, and the appropriate pH is 5-8. The soil moisture is required to be 60-80% of the maximum soil water holding capacity. If there is too much water in the early stage of growth, the overground part will affect the expansion and growth of fleshy roots. If the water is insufficient in the late growth stage, the taproot can not be fully expanded, and the yield will be reduced. Too sticky soil or immature base fertilizer will hinder the normal growth of fleshy roots and produce deformed roots.

3, watering and fertilizing carrots at seedling stage:

When the seedlings grow to 7-8 leaves, hoe and squat the seedlings when the soil is wet, promote the downward extension of the main roots and the development of fibrous roots, and inhibit the excessive growth of leaves. After 10 ~ 20 days, when the fleshy roots swell obviously, they should be fully watered and kept moist frequently. When planting 3 ~ 4 real leaves, 2 ~ 3kg of ammonium sulfate, 3 ~ 4kg of calcium superphosphate and 2 ~ 3kg of potassium fertilizer should be applied per mu.

When the seedlings are fixed, each mu should be watered with ammonium phosphate 10 kg and potassium chloride 3 ~ 4 kg to promote the robust and rapid growth of seedlings. When fleshy roots begin to grow, topdressing quick-acting organic liquid fertilizer or ammonium phosphate, potassium chloride, etc. Harvesting spring carrots 90 ~ 100 days after sowing; Carrots in autumn are harvested and stored before the arrival of severe winter.

Question 7: Carrots planted in Tongzhou, Beijing for several months are semi-cold-tolerant vegetables, and the temperature requirements for vegetative growth and reproductive growth are different. Seeds can germinate at 4~6℃ and start to grow at 8℃; 18~20℃ for about 10 days. The seedlings can tolerate the low temperature of -3~ -4℃ for a short time, and can grow normally at the high temperature above 27℃.

The optimum temperature of carrot germination period is 20~25℃, so it is usually planted in summer and autumn and harvested in autumn and winter.

Question 8: How many seasons does radish ripen in a year? According to the growth period of white radish and carrot, it can't be harvested all year round.

In China, the flowering period of white radish is April-May every year, and the maturity period of radish is May-June every year.

Carrots are harvested in spring and autumn.

Harvesting spring carrots after sowing for 60-90 days; From June to August.

Autumn carrots are generally harvested after sowing and before the soil freezing period of 100 days. August of 10 to early of 10.

However, white radishes and carrots can be stored in winter. However, due to different storage conditions, the storage quality is also different. Not as delicious as fresh radish. The main reason is excessive water loss during storage.

There will be one in the morning market or supermarket.

Question 9: The planting time of carrots in the north: the sowing time is March -65438+ 10, and the growth period is 50- 100 days.

Carrot, alias basic radish, clove radish, gourd radish, also known as fenugreek, cabbage head, yellow radish and so on. , an umbrella-shaped biennial herb with fleshy roots as vegetables.
