When does the cherry tree sprout?
Cherry tree is a small deciduous tree of Rosaceae and Prunus, and its height can reach 8 meters. The flowering time is around March, and the first leaf is open; Fruit ripens from May to June.
Planting cherries
1. Choose a garden? To plant and cultivate cherries, we must choose areas with high terrain, no water accumulation 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 and high yield, and of course, those with strong resistance.
3. sow and raise seedlings? Seeding and seedling raising in the spring of the second year after seed collection do not need to accelerate germination, and the germination rate of cherries is high, and no special treatment is needed.
4. planting fixed plants? Here I want to make a detailed introduction. Cherry planting is best in autumn, because the northern spring is dry, and the traditional spring seed moisture 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, bees can be raised artificially.
7. Fruit harvesting? Harvest in batches, and keep the fruit stalks when harvesting, preferably after the dew is dry on sunny days or when the temperature is low in the evening.
Extended data Cherry (scientific name: Cherry) is a general term for some Prunus plants, including Leah, Leah, Rosaceae subgenus and so on. Trees, 2-6 meters high, with gray bark. Branchlets grayish brown, shoots green, glabrous or sparsely pilose. Winter buds ovate, glabrous.
Fruit can be eaten as fruit, with bright color, crystal beauty, red as agate, and yellow if frozen. Fruit is rich in sugar, protein, vitamins, calcium, iron, phosphorus, potassium and other elements.
Cherry is mainly distributed in the United States, Canada, Chile, Australia, Europe and other parts of the world. The main producing areas in China are Heilongjiang, Jilin, Liaoning, Shandong, Anhui, Jiangsu, Zhejiang, Henan, Gansu, Shaanxi and Sichuan.
morphological character
Trees, 2-6 meters high, with gray bark. Branchlets grayish brown, shoots green, glabrous or sparsely pilose. Winter buds ovate, glabrous. The leaf blade is ovoid or oblong-oval, 5-12cm long and 3-5cm wide, the apex is tapered or caudate, the base is round, the edge has sharp double serrations, the tooth tip has small glands, the top is dark green, nearly hairless, the bottom is light green, it is sparsely pilose along or between veins, and the lateral veins are 9-1/kloc-0. The petiole is 0.7- 1.5 cm long, puberulent and has 1 or two large glands at the top. Stipules caducous, lanceolate, with pinnate glandular teeth
Inflorescence corymbose or subumbellate, with 3-6 flowers, the first leaf is open; Involucre obovate-elliptic, brown, about 5 mm long and 3 mm wide, with glandular teeth on the side; Pedicel 0.8- 1.9 cm long, sparsely pilose; Calyx tube is bell-shaped, 3-6 mm long and 2-3 mm wide, and the outside is puberulent. Sepals triangular-ovoid or ovoid-oblong, with acute or obtuse apex and entire margin, half or half the length of calyx tube.
Petals are white, ovoid, and the apex is concave or dichotomous; Stamens are 30-35, and the number of cultivators can reach 50. Style subequal to stamens, glabrous. Drupe is nearly spherical, red and 0.9- 1.3 cm in diameter. The flowering period is from March to April, and the fruiting period is from May to June.
growing environment
Born on sunny slopes or beside ditches, often cultivated, with an altitude of 300-600 meters.
Cherry is a fruit tree that likes light, temperature, humidity and fat. It is suitable to grow under the climatic conditions of annual temperature 10- 12℃, annual precipitation of 600-700 mm, and annual sunshine hours of more than 2,600-2,800 hours ... The time when the daily average temperature is higher than 10℃ is 150-200d, in winter.
If there is freezing damage in the local area, cherry orchard can choose the northwest slope where the temperature rises slowly and the air circulates in spring. Considering that the cherry root system is shallow and easy to be blown down by the wind, the garden should be in an area free from wind damage, and the soil is sandy loam with loose soil and deep soil layer.
