Cultivation method for reducing stiff fruits and big and small fruits generated in fruiting period of citrus reiculata Blanco

Abstract

The invention relates to the technical field of citrus reiculata Blanco planting, and particularly discloses a cultivation method for reducing stiff fruits and big and small fruits generated in the fruiting period of citrus reiculata Blanco, and the cultivation method comprises a fruiting flower bud and next-year fruiting mother branch cultivation method and a fertilization improvement method; the fertilization improvement method comprises the steps of spraying a flower promoting and strengthening foliar fertilizer and applying a root fertilizer, wherein the spraying of the flower promoting and strengthening foliar fertilizer comprises the steps of spraying a foliar fertilizer I in a flower bud differentiation stage and spraying a foliar fertilizer II in a flower bud stage. According to the cultivation method for reducing stiff fruits and big and small fruits generated in the fruiting period of citrus reiculata Blanco, sufficient nutrients are more reasonably provided for all stages of plants, the root activity of citrus reiculata Blanco is improved, the nutrition of the upper portion and the lower portion of a tree body is adjusted, and the photosynthesis efficiency is improved through measures such as fruiting mother branch cultivation, root fertilizer application and foliar fertilizer application in different periods; therefore, flower bud differentiation is promoted, pollen activity is improved, fruit development is facilitated, the stiff fruit rate is reduced, fruit expansion is promoted, large and small fruits are reduced, and the quality and yield of citrus reiculata Blanco are improved.

Description

technical field [0001] The invention belongs to the technical field of fertile mandarin planting, and in particular relates to a cultivation method for reducing the generation of stiff fruit and large and small fruits during the fruit setting stage of the fertile mandarin. Background technique [0002] Wo tangerine has the characteristics of strong tree vigor, strong fruit bearing ability, less fruit drop in winter, long fruit bearing harvest period, plump fruit, beautiful appearance, tender flesh, sweet and soft taste, etc. Wo citrus is the fastest growing and most profitable citrus variety in Guangxi in recent years. During the cultivation of wo citrus, it is easy to appear stiff fruit and large and small fruits. The main symptom of stiff fruit is that the growth rate of young fruit slows down or even stops during the fruit expansion period. Growth, in the mature stage, the peel is stiff, the surface is rough, the pulp capsule and flap are dehydrated, and the fruit is cork...

AI Technical Summary

Problems solved by technology

The causes of stiff fruit and small fruit are: low root activity, weak absorption of nutrients, resulting in insufficient nutrient accumulation in the tree, resulting in blocked flower bud differentiation, poor flower and fruit development, and nutrient element imbalance. Fruit expansion is blocked; vigorous growth of summer shoots reduces summer Root pumping consumes nutrients and young fruit competes for nutrients, resulting in slow fruit drop and small fruit expansion; using hormones to preserve fruit, improper chemical control of shoots, and paclobutrazol and flumetriamine are plant growth regulators, which have the effect of delaying plant growth and can be used to Control summer shoots, but improper use (high concentration, high temperature spraying, etc.) will cause more stiff fruit

Stiff fruit has no commodity value, and small fruit will reduce the unit price of Wogan. Stiff fruit and small fruit will seriously affect the income of fruit farmers
