What are the new methods to promote the cultivation of longan in four seasons?

The climate is unusually warm this year, which makes growers feel a little annoyed. Some litchi techniques gradually turn white and longan gradually turns red, but flowers are not common and grow small and bright red leaves. Some grow buds, others grow leaves. In the past, it was full of flowers now. If litchi and longan are not in full bloom, we should try our best to accelerate germination and grow ears. First, you can stimulate the growth of buds by pruning branches. In fact, moderate pruning is used to prune weak branches, pine branches, pest branches, dead branches and cross branches in the trunk.

Spraying the leaves for 2-3 times, the micro-fruit-supplementing power (mainly phosphorus, calcium, potassium and magnesium) is 500 times+the micro-flower-supplementing power (mainly zinc, boron and magnesium) 1000 times. This factor is a key trace element for flower promotion and can promote flower bud differentiation. In the soil layer, promoting the application of chemical fertilizer is mainly used to improve the nutritional composition of tree stems before flowering. Rinsing 30kg water with 3-5ml ethephon+compound polypeptide chain+carbohydrate or washing 30kg water with 8- 10ml anthocyanidin (produced in Qinzhou)+compound polypeptide chain+carbohydrate once can kill the lobule and control flushing.

Before and after the winter solstice solar terms, chlormequat should be used to control the maturity of winter bamboo shoots to prevent them from sprouting. When the buds grow in February and March in early spring, the leaves should be removed immediately and the terminal buds should be removed to promote the growth and development of lateral buds. If you can't defoliate and germinate immediately, you can choose chlormequat to avoid pruning and control water to prevent winter buds, promote flower bud differentiation, pay attention to the filling of fertilizer when flowering to prevent fertilizer deficiency, and it is best to use fertilizer water and spray zinc leaves when flowering.

There are too many rainy days to prevent. Now you can cut pears professionally to prevent the fruit from falling for the third time. Moderately topdressing organic fertilizer with high potassium content and spraying pesticides will stop the water seepage of leaves at the bottom of leaves! Can prevent fruit from losing weight! At this time, the fertilization stage is from April to May, accounting for about 15% of the annual fertilization. Fertilization in this period has obvious effects on sprouting summer shoots, expanding flower ears, avoiding fruit dropping and improving fruit hanging rate. It is of great practical significance to promote the emergence of summer shoots and get rid of the situation of bearing fruit in big and small years.
