When does the big cherry tree bloom?
I know the flowering time of cherry blossoms in Osaka, Japan. It's basically from mid-March to mid-April, but the flowering time also depends on the weather. It is normal to bloom half a month earlier or half a month later.
When do cherry trees usually bloom?
Generally, the north separates in March and April, and the south blooms in January and February.
Cherry blossoms blossom and bear fruit in a few months.
Landlord, cherry blossoms are mostly in March-April, and the flowering and fruiting time is generally in June-July. ...........
In which month do cherry trees in the north blossom and bear fruit for two years?
Flowering from March to April.
April to May, then May to June.
Cherry habit:
The growth of cherry root system has strict requirements for soil permeability. When cohesive soil or soil is poorly managed, the distribution of root system becomes shallow obviously, which leads to premature senescence of aboveground parts.
Cherry planting steps:
1. Garden selection: Planting and cultivating cherries must choose areas with high terrain, no stagnant water and low groundwater level, and neutral or slightly acidic sandy loam with deep soil layer and good air permeability is suitable (the soil can also be improved by adding organic fertilizer).
2. Variety selection: It is best to choose varieties with large fruit, early maturity, high yield and, of course, strong resistance.
3. Seeding and seedling raising: Seeding and seedling raising in the spring of the second year after seed collection, no need to accelerate germination, high cherry seedling emergence rate and no special treatment.
4. Planting plants: It is best to plant cherries in autumn, because the spring in the north is dry and the water content of traditional spring seeds is difficult to control. Moreover, if spring is planted early, the temperature fluctuates greatly and it is easy to freeze. Cherry seeds germinate late, the root system grows slowly in spring, and the survival rate is low. Autumn ploughing will not have such a problem. It is best to use the method of deep planting and shallow burial in small pits.
5. Water and fertilizer management: As mentioned above, the characteristics of cherry regeneration, so we should pay attention to ensure timely watering during drought and timely drainage for flood control during rainy season. Fertilize 3 times during the growing period, and generally apply a small amount of organic fertilizer when watering.
6. Pollination at flowering stage: Pay attention to cross pollination, and bees can be raised artificially.
7. Fruit harvesting: harvesting in batches, keeping the fruit stalks when harvesting, preferably after the dew is dry on sunny days or when the temperature is low in the evening.
In what month do cherries bloom?
Cherry blossoms in April. When the average temperature reached 10℃, the flower buds began to sprout (early April in Beijing). Flowering begins when the daily average temperature reaches about 15℃ (about 10 days in April in Beijing), and the whole flowering period is about 10 days.
The process of cherry trees from flowering to fruiting in a year.
Flowering in March, the first leaf opens; Fruit ripens from May to June.
China Cherry: Generally, it only takes 40-50 days.
European sweet cherry: 40 days early, 50 days middle and 60 days late.
The flowers are white, with a diameter of about 1.5~2.5cm, and the calyx tube is hairy; 3~6 clusters form racemes. The fruit is nearly spherical, with a diameter of 1~ 1.5cm, and is red.
The main process of flowering and fruiting
1. Cells on anthers produce pollen grains.
2. Pollen falls on the stigma.
3. The pollen tube germinated by pollen grains extends into the ovule, and * * * passes through the pollen tube to fuse with the egg cell.
4. The ovule develops into a seed, and the fertilized egg develops into an embryo.
5. Ovaries and other structures produce fruits.
Detailed process of flowering and fruiting
1. After the bud matures, the perianth gradually opens, then the pistil stamens extend, the stigma secretes mucus, and at the same time, the anthers crack and the pollen spreads.
2, pollination: rely on insects, wind, etc.
3. Double fertilization: Pollen grains germinate on the stigma. With the elongation of pollen tube, vegetative nucleus and sperm nucleus enter embryo sac. Subsequently, 1 sperm fertilized, combined with egg cells to form a zygote, and then developed into an embryo (2n). In addition, 1 sperm nucleus and two polar nuclei are fertilized to form endosperm nucleus (3n), which will develop into endosperm (3n) later, so this process is called double fertilization. And finally develop into seeds through subsequent double fertilization.
4. Fruit development: Generally speaking, fruit development and plant fertilization occur at the same time. Usually, during pollination, due to the enzymes secreted by pollen tubes, tryptophan is converted into auxin, thus the ovary grows. In addition, fertilized seeds can also provide growth factors and fruit growth.
5, mature process:
Hardness change: with the fruit ripening process, the peel texture gradually changes from hard to soft, mainly due to the increase of soluble pectin in the peel cell wall and the decrease of protopectin, which makes the cells lose cohesion, disperse the cells and soften the pulp. The different components of pulp cell wall and the number of stone cells in pulp will affect the hardness of pulp. Temperature, ethylene, naphthylacetic acid and other hormones and growth regulators will reduce the hardness of fruit.
Aroma: In the process of fruit ripening, some fruit aromas will be produced, including aliphatic and aromatic esters and some aldehydes.
Sweet and sour: the starch accumulated in the fruit is gradually hydrolyzed and converted into soluble sugar during the ripening process, which makes the fruit sweet. Immature fruit contains many kinds of organic acids, which make the fruit sour. The main organic acids are malic acid, citric acid and tartaric acid. As the fruit matures, some acids are converted into sugar, some are oxidized, and some are neutralized by potassium ions and calcium ions, so the acidity decreases.
Astringent taste: The fruit is astringent when it is immature, because there are more tannins in the cell fluid. Tannin is oxidized by peroxidase into peroxide without astringency during fruit ripening, or condensed into colloidal substance insoluble in water, so that astringency disappears.
The development of cherry fruit generally goes through three periods.
first stage
The volume and weight of the fruit increased rapidly from the expansion of the ovary to the hardening of the stone after flowering, and the stone also increased correspondingly. The growth rate of the early, middle and late-maturing varieties of the same variety was similar (cherry 9- 14 days).
Secondary phase
From the beginning of hardening to the completion of hardening (hard core stage), fruit growth is slow or not obvious, and the length of time varies with species and varieties.
third
In the second rapid growth period of fruit, the pulp thickness increased obviously, especially before harvesting.
When do cherry trees and cherries blossom and bear fruit every year?
What month are cherry blossoms in, from March to April?
When will the fruit mature? April-May results, May-June maturity.
What are cherry blossoms like? Such as plum blossoms.
What color is that? White and pink
When do cherry trees grow leaves?
It depends on the place. Now, except in extremely cold places, all flowers are sprouting, and most of them bloom in mid-April.
In what month do cherries usually ripen?
According to the variety and planting area of cherry, the ripening time is also different. In China, cherries usually ripen from May to mid-June every year. Because of different regions and temperatures, the maturity time will be slightly different. Early cherries are usually listed in May of the solar calendar and last for more than a month, because cherries are not suitable for long-distance transportation. Late cherry came on the market almost in the middle and late May, and almost disappeared in the middle and late June.
The maturity of individual greenhouse cherries is also different.
In mid-March, the cherries in the greenhouse in Dalian ripened.
Cherry ripens in Yantai greenhouse in the middle and late April
In early May, southern cherries began to ripen.
Yantai cherry began to ripen in the middle and late May.
When will the cherry blossoms bloom (exactly, what day is it! )
In the world of April, the flowers have withered, and the peach blossoms in the ancient temples have just bloomed. There is a monthly difference between north and south! Early March at the earliest! The higher the temperature, the earlier and the later!
