Apricots in the northeast of China are born under the broad Chaoyang hillside shrub or miscellaneous forest at an altitude of 400- 1000 meters. Prunus armeniaca is mainly produced in northern China, both cultivated and natural, especially in Hebei, Shanxi and other places, and also in Shandong and Jiangsu. Apricots are naturally distributed in Yili, Xinjiang. Choose * thick and fertile flat land for the study garden, and avoid planting the garden on shady land, otherwise it will cause poor growth and development of apricot trees, leading to limited yield.
Before planting apricot trees, we should pay attention to farming, dig planting holes at regular intervals, backfill compost organic fertilizer and fine soil, and apply mature soil. It has a very good effect on improving the growth rate and survival rate of green seedlings. After soaking strong almond saplings, they can be planted in caves. Planting time in autumn is before soil freezing, and planting in spring is after soil freezing.
After apricot trees are fertilized and planted, sufficient base fertilizer, product organic fertilizer and microbial fertilizer should be applied, usually after fruit picking in autumn. Organic fertilizer should be applied once in the early fruit-bearing period and high-yield period, and fertilization should be balanced according to nutritional components. The fertilization time is controlled in the first two stages of flowering, withering and hard core, and the third stage is mainly phosphorus and potassium fertilizer. Fertilizers are sprayed on the leaves of apricot trees after fruiting. The main fertilizers are calcium carbonate and potassium dihydrogen phosphate.
Water management method: Inject water into apricot trees 1 time before germination, hard core stage, fruit picking and soil freezing. After watering, attention should be paid to covering plastic film and effectively pouring fertilizer solution, which can significantly improve the actual effect of fertilizer efficiency.
Pruning and pruning fruit trees should cut off the vertical branches to prevent the trunk from opening, so pull the branches slowly to promote the fruiting branches to draw conclusions in advance. Subsequently, the fruit branches are contracted to repair the growth and development ability of the branches. The conclusion ability of apricot trees can be restored by cutting short long fruiting branches. Before the fruiting period, it is necessary to pick the top, pull the branches and smear the buds, which can improve the summing-up ability of apricot trees.
Disease Control Apricot trees are prone to diseases such as apricot disease, gummosis and budding insects. Spraying agricultural streptomycin can prevent apricot diseases, and prevention should be improved at ordinary times. Spraying 5 degrees omethoate can prevent gummosis, and using 2500 times of 50% pirimicarb wettable powder can prevent budding insects.
