Plums can be planted after autumn and before germination in March of the following spring, but it is best to plant in autumn, which germinates early and grows fast. However, plum seeds should be sown in 165438+ 10 (before soil freezing), and the sowing depth is about 10- 12 cm. After sowing, they should be watered every 30 days in winter and every 7- 10 days in March.

Plum trees usually have a long growth cycle, which usually takes 3-5 years. After this period, they may not bloom again.

How to plant plums

The best planting density of plum is 2× 1 m, and the whole stone is soaked in warm water for two to three days to accelerate germination. The seeds of well-developed embryos are planted in sand to keep the soil moist and sunny and accelerate its growth.

Matters needing attention in plum planting management

1. Variety selection: Variety should be determined according to local climatic factors. Generally, the varieties with long growth period and large fruit are black amber, royal gem, American late-maturing plum, President Lee and so on.

2. Planting plots: generally, loose and fertile soil is selected for planting. When planting, the row spacing of each sapling should be about 3.5m * 4.5m, and 32-57 saplings can be planted per mu.

3, shaping and pruning: plum trees can generally choose natural round-headed trees and slender spindle trees for shaping. When selecting natural round-headed trees, more branches should be used in the process of shaping. The slender spindle shape is more suitable for varieties with high germination rate, low branching rate and few branches. In the process of plastic surgery, you can use the method of short cutting to make it grow branches, and then use the long opening angle of the branches.

4. Prevention: The key disease of plum trees is bacterial perforation, and there are generally two common prevention methods. Firstly, increase the application of organic fertilizer, improve the soil and enhance its antiviral performance; Second, spray agricultural streptomycin in time.
