Cultivation techniques of Prunus mume

Biological characteristics: plum adaptability is strong, cold. It likes warm and humid climate, needs sufficient sunshine, flowering temperature has great influence on yield, lower than-5-6℃ or higher than 20℃ has obvious influence on fruit setting rate, annual average temperature 16-23 ℃, annual average rainfall above 1000mm is the most suitable cultivation area. To soil requirement is lax, with loose fertile, soil layer is deep, the sandy qualitative loam with good drainage is good. Fear of waterlogging, drought tolerance, low ridge wet land is not suitable for planting.

Cultivation techniques seed, grafting, layering and other methods of reproduction.

Seed propagation: harvesting seeds in June and sowing in autumn. Or the seeds will be stored in the sand winter, the following February-March spring sowing. Because seed reproduction is not easy to maintain the original variety characteristics, so only for rootstock or breeding seed selection. It is generally based on grafting.

Grafting: branch grafting or bud grafting, rootstock with apricot, plum, plum and other seedlings. Branching should be carried out before spring germination, bud grafting should be carried out from late August to early September, cloudy days are appropriate, avoid rainy days. After grafting survives, it is planted before germination in the following spring.

Field management: After planting, field management such as intertillage, weeding, fertilization, irrigation, drainage and pruning should be carried out. The amount of fertilizer applied varies with soil properties, age and growth potential. Pre-flowering fertilizer and fruit picking fertilizer were mainly available fertilizer. After defoliation, winter manure should be applied again, mainly organic fertilizers such as decomposed compost and manure, and phosphorus and potassium fertilizers. Shaping pruning should be thin and light, and the branches should be evenly distributed. In winter, cut off long branches and keep short fruit branches. Bud wiping and topping are carried out in late spring and early summer to accelerate crown formation.
