Problems solved by technology

This phenomenon generally occurs in two situations: one is that the tree grows too long and consumes too much nutrients in the body, so that there is not enough nutrients in the body to supply the conditions required for differentiating flower buds; Insufficient nutrient accumulation for one year, or the tree itself is very weak and does not have enough nutrients, resulting in failure to bloom and bear fruit

Embodiment 1

[0013] For trees with poor tree potential, after harvesting in May, 30 kg of farm organic fertilizers such as pig and cow dung, 1 kg of calcium magnesium phosphate fertilizer, and 0.8 kg of urea were applied to the plants. Prune immediately after the fruit is harvested, and use heavy cutting and short cuts to promote good summer and autumn shoots. Spray 0.5% urea twice on the leaves. After observation, adopting the above method, the rate of flowering and fruiting of weak trees can reach more than 96%.

Embodiment 2

[0015] For overgrown trees, it is necessary to reduce the application of nitrogen fertilizer and increase the amount of phosphorus and potassium fertilizers. After the fruit is harvested in May, 20 kg of farm organic fertilizers such as pig and cow dung, and 0.8 kg of calcium, magnesium, and phosphate fertilizers are applied to the plants. Start pruning in August, delete more large branches and large shoots, and combine with mild short cuts to inhibit vegetative growth and promote short, strong and substantial spring and autumn shoots. Some strong branches that grow too vigorously can be circumcised or circumcised with iron wires between July and August to control growth and promote flower bud formation, and the iron wires will be removed in the spring of the following year. Spray 0.2% potassium dihydrogen phosphate solution twice on the leaves. Through observation, adopting said method, the flowering and fruiting rate of overgrown loquat trees reaches more than 97%.

Abstract

The invention discloses a method for preventing non-flowering of loquat. The operation method comprises the steps that sufficient nitrogen, phosphorus and potassium fertilizers are applied to trees poor in tree vigor, and pig manure, cow manure and other farmyard organic manure, fused calcium magnesium phosphate and urea are mainly used. For over-growth trees, the application amount of the nitrogen fertilizer needs to be reduced, and the application amount of the phosphorus and potassium fertilizers needs to be increased. With the cooperation of foliar fertilization, tree bodies are pruned reasonably. Over-growth branches are subjected to girdling or cerclage wiring, so that the tree vigor keeps moderate. By means of the method, the problem that loquat trees do not flower or fruit can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, in particular to a method for preventing and treating loquats from not blooming. Background technique [0002] The loquat fruit tree does not bloom, mainly because the tree body has no differentiated flower buds. This phenomenon generally occurs in two situations: one is that the tree grows too long and consumes too much nutrients in the body, so that there is not enough nutrients in the body to supply the conditions required for differentiating flower buds; Insufficient nutrient accumulation for one year, or the tree itself is very weak and does not have enough nutrients, resulting in failure to bloom and bear fruit. Contents of the invention [0003] The object of the invention is to provide a production management method with low cultivation cost, which can promote loquat flowering and fruiting and increase fruit tree yield, aiming at the problem of loquat fruit trees not blo...
