I know. Tell me how to raise plum trees.

Conservation cultivation management technology

(1) Plum blossom is a positive tree species and should be planted in sunny places. It should be placed in a sunny place in the greenhouse in winter, and the temperature should not be lower than 5℃. From June 5438 to early February, the plum blossom was moved to a greenhouse with a high temperature, and the room temperature was kept between 7℃- 10℃. It can promote its flowering during the Spring Festival. After flowering, it can be extended by moving it to a greenhouse at 5℃. Due to the shallow soil of plum blossom bonsai, if it is not properly managed in summer, it is easy to cause thin branches and leaves of plum blossom, so attention should be paid to the heatstroke prevention of plum blossom in summer.

(2) After watering plum trees into the vigorous growth period, the water demand is large, so it is necessary to water frequently to keep the basin soil moist, but no water can be accumulated. May-June is the key period to control flower bud differentiation, and water should be properly controlled to promote flower bud differentiation. In July, normal watering is necessary. If there is no water at this time, it is easy to cause leaves to fall. /kloc-after 0/0, plum trees enter dormancy period, so water should be reduced. After 65438+February, water it once a week, and it can bloom before the Spring Festival.

(3) Fertilization During the growth period of plum trees, dilute liquid fertilizer was applied once every 20 days, and phosphorus and potassium fertilizer were applied twice in June 5438+early February.
