Mango early flowering processing method

Abstract

The invention belongs to the field of agriculture technology and in particular relates to a mango early blossoming processing method. The method includes the following steps: (1) in winter from November to December, when the flower head of a mango flower sprouts at a length of 10-15cm, a main flower head is picked from the flower head at a place 4-5cm from a stem base, and at the same time, all side flower clusters are picked at a position 4-5cm from the stem base; (2) in the next year from late January to February 20, the whole stem base of the flower head is cut off from the position of a first dense nodal bud. Through conducting twice flower head removing, a mother shoot is able to sprout twice and the head flower is able to blossom, so that the blossoming period and fruit bearing period of mango early blossoming are delayed to from February to the spring of April. The method can remarkably postpone mango blossoming period, reduce blossoming amount, increase proportion of female flowers, increase mango fruit bearing rate and output, remarkably postpone fruit maturing period, increase benefits from mango culture, reduce workload, reduce tree nutrition consumption, and is especially suitable to dry-hot valley area, etc. of Jinsha river.

Description

Technical field [0001] The invention belongs to the field of agricultural technology, and is specifically a method for processing mango early flowering. Background technique [0002] In some mango-producing areas in my country, some mango trees have flower spikes from November to December each year, and early flowering occurs. The early flowering period and fruit setting period are in the winter. It is very vulnerable to low temperature or rainy weather, and it is difficult to set fruit. Falling flowers and fruit or parthenocarpy, low or no yield. [0003] The hot and dry valley of the Jinsha River is the main production area of ​​late-ripening mangoes in my country. As of 2015, the planting area is nearly 600,000 mu. Due to the comparative benefits of planting mangoes, it is still developing rapidly. Because the rainy and dry seasons are distinct in this area, the rainy season is from June to October, and from November to May of the following year. The relatively low temperature a...

Problems solved by technology

Due to the distinct rainy and dry seasons in this area, the rainy season is from June to October, and the dry season is from November to May of the following year. The relatively low temperature and drought in winter are suitable for the differentiation of mango flower buds. Flowering, if it is allowed to bloom and set fruit naturally, because its flowering period and fruit setting period are in winter and encounters low temperature, it will cause flower drop and fruit drop or parthenocarpy, resulting in low or no yield. Prevention and control increases the production cost and pesticide residue pollution; usually during November-December, when the flower spikes are 10-15cm out, the whole flower spikes are manually removed from the base of the flower spikes, and about 30 days after the flower spikes are removed, they will be removed again. The short bunches of cluster-like flower spikes will be drawn out again. The flowering and fruit-setting periods of the flower spikes are generally from December to January in winter. Most of the flower spikes should be removed from the base of the flower spikes again. Cluster-like flower spikes are used to flower and fruit-set. This treatment method can obviously delay the flowering period, reduce the amount of flowers, increase the proportion of female flowers, and increase the yield of mangoes. The amount of labor increases the nutrient consumption of the tree body and weakens the tree vigor
