Method for preparing special leaf fertilizer for mangoes from ageratina adenophora

Abstract

The invention discloses a method for preparing a special leaf fertilizer for mangoes from ageratina adenophora. The method comprises the steps of crushing aboveground stalks of purple ageratina adenophora, conveying the crushed stalks into an extracting tank, firstly, extracting with water, and then, filtering to obtain a water extraction solution; extracting filter residues by using ethanol, and filtering after extracting to obtain an ethanol extraction solution; and mixing the water extraction solution and the ethanol extraction solution, and adding a certain quantity of ethephon, trace elements, humic acid and monopotassium phosphate into the mixed solution to obtain the special leaf fertilizer for mangoes. By using the leaf fertilizer prepared by using the method disclosed by the invention, the chlorophyll synthesis of leaves can be promoted, the photosynthesis of the leaves can be enhanced, the flower bud differentiation of mango branches can be promoted, bacterial diseases, fungal diseases and pests can be prevented and controlled, the pistillate flower ratio of mango flowering branches can be increased, the amount of middle-sized fruits can be increased, huge fruits can be avoided, the yield of the mangoes can be increased, and the quality of the mangoes can be improved.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a method for preparing mango-specific foliar fertilizer by using Eupatorium adenophorum. Background technique [0002] Eupatorium adenophora (Ageratina adenophora) is a perennial herb or subshrub of Compositae, native to Mexico and Costa Rica in Central and South America. In the 1940s, it was introduced from Burma to the southernmost counties of Cangyuan and Gengma in the Lincang area of ​​Yunnan Province. It is now widely distributed in Yunnan, Guizhou, Sichuan, Guangxi, Chongqing, Hubei, Tibet and other provinces in the southwest. And spread east and north with the southwest wind. By 2012, Eupatorium adenophorum was distributed on 80% of the land in Southwest China, and the distribution area in Yunnan Province alone reached more than 2.5 million hectares. Due to the strong reproductive ability and adaptability to the environment, Eupatorium adenophorum can grow in arid ...

Problems solved by technology

The main reason for the large-fruited mangoes is that the proportion of female flowers in mangoes is relatively low, which directly leads to a limited number of fruits. In order to increase the yield, farmers often apply more fertilizers, which leads to a larger single fruit weight.

In the market, large-fruited mangoes may make consumers mistakenly believe that they are caused by the spraying of fruit bulking agents and other hormones. Therefore, the sales of large-fruited mangoes are not optimistic.

At the same time, once the large-fruit mango rots, the loss will be greater
