Flowering and girdling plum trees with the age of 12 and 15, which have entered the full-bloom stage, are girdled at the full-bloom stage. Methods: Cut the trunk of plum tree about 15 cm from the ground with a sharp knife for 2 circles, with a width of 4,6 mm, reaching the xylem and peeling off the skin. Ring base fertilizer. Base fertilizer is a basic fertilizer that can supply many nutrients to plum trees for a long time.

For mature plum trees, farmyard manure should be applied to each base fertilizer.

Plums mainly bear short fruit branches and bouquets of short fruit branches, and pruning should be based on the principle of light cutting and long release, ventilation and light transmission. In the first year, fruit tree shaping was the main task, and the amount of pruning was appropriately increased to lay the foundation for high yield in successive years. Perennial trees are basically sprayed with 500 times of Loeb or phoxim powder at the end of flowering, and then lightly hoed.

Picking up the fallen fruit and transporting it out of the orchard for destruction can destroy most of the plum bees. At the end of the blooming period, carefully spray the crown 1 time 1500 times. Lethburn or plum trees can be topdressing before flowering, so that the trees are rich in nutrition and bloom more, and the pollination rate can be improved when flowering. You can roll it up with a feather blanket in the orchard, comb some flowers at the bottom of the fruit branches properly, and prevent pests. Pay attention to red leaf disease and heart eater.

In order to produce pollution-free plum fruit, in the flower bud expansion period of plum tree, 6. Pest control: At the early stage of fruiting, the fruit trees should be sprayed with sulfur mixture, Bordeaux three nights, zineb, etc. It is generally more appropriate to apply it twice. Do a good job in soil, fertilizer and water management (formula fertilization, increased application of organic fertilizer and timely watering) to provide sufficient nutrition for trees.
