Citrus plant cell sap concentration regulation and control girdling-free cultivation method

Abstract

The invention discloses a citrus plant cell sap concentration regulation and control girdling-free cultivation method. The method comprises the following steps of cultivating spring shoots as fruitingbranches and fruiting mother branches of the next year every year, applying water flush fertilizer to roots from January to February every year, applying root system repair fertilizer in a summer shoot period and within 10-20 days after blossom fall every year, and spraying Yuhuanling No.2 foliar fertilizer in a spring shoot period, so that flower promoting, flower strengthening and spring shootvegetative growth requirement reducing are achieved; in the summer shoot period, spraying Yuhuanling No.2 foliar fertilizer to supplement tree nutrition and reduce the summer shoot nutritional growthrequirement; spraying Yuhuanling No.2 foliar fertilizer in autumn shoot and winter shoot periods to promote flower bud differentiation in the next year and reduce the nutritional growth requirements of autumn shoots and winter shoots; trimming useless shoots of the grown spring shoots, grown summer shoots, the grown autumn shoots and the grown winter shoots. Through combination of the water flushfertilizer applied to the roots, the root system repair fertilizer and the foliar fertilizer sprayed to the leaf surfaces, the concentration of cell sap of plants is increased, flowering and fruit setting are facilitated, girdling is avoided, consumption of manpower and material resources is reduced, and losses caused by girdling are reduced.

Description

technical field [0001] The invention relates to the technical field of citrus cultivation. More specifically, the present invention relates to a cultivation method for exempting circumcision by regulating the cell fluid concentration of citrus plants. Background technique [0002] Citrus belongs to the Rutaceae plant, including Wogan, Shatangju and so on. The rapid return on investment of citrus and high economic benefits make it widely favored by growers, and the increasing market demand is constantly stimulating the scale of domestic citrus planting. Ring cutting is a commonly used agricultural technique in citrus cultivation. During the flowering stage, appropriate ring cutting of branches can temporarily hinder the downward transport of organic matter, increase the accumulation of nutrients in the upper part of the wound, promote flower bud differentiation and improve fruit quality; Circumcision increases the concentration of plant cell fluid and inhibits flower and fr...

Problems solved by technology

During the whole process of circumcision until the tree body recovers and heals, due to the affected tree body function, the nutrient absorption and water transport functions are limited, causing a series of changes that affect photosynthesis, resulting in a decrease in the nutrient accumulation of the tree itself, Coupled with the large amount of nutrients consumed by flowering, fruiting and wound healing, in the absence of nutritional remedies, it will lead to subsequent tree vigor decline and a series of adverse consequences; even if a series of nutritional measures are used to protect the tree, it is difficult. Achieving sustainable yield and extending tree life

On the other hand, circumcision operation is one of the highly professional agricultural operations. It needs to be operated with specific cutter heads and techniques according to the specific analysis of the tree body. If the cut is deep, the tree body will be damaged and it will easily cause citrus yellowing. Recession; cutting shallow, the effect of preserving flowers and fruits is not good

Not to mention the cost of manpower and material resources, the loss of production caused by low repeatability of operations is even more difficult to estimate
