Description

Root-promoting and green-turning liquid fertilizer for young coconut trees and preparation method and fertilizing method thereof

Technical Field

The invention belongs to the technical field of fertilizers, and relates to a liquid fertilizer, in particular to a coconut young tree root promoting and green turning liquid fertilizer, and a preparation method and a fertilizing method thereof.

Background

Coconut has high economic value, and all parts of the whole plant have application. The unripe endosperm ("pulp") can be consumed as tropical fruit; coconut water is a palatable refreshing drink; the mature coconut meat contains 70% of fat, can be used for extracting oil, and can be processed into various candies and cakes; the coconut shell can be made into various utensils and artware, and can also be made into activated carbon; the coconut fiber can be used for making brushes, carpets, cables and the like; the tree trunk can be used as a building material; the leaves may be roofed or braided; the root can be used as a medicine; besides drinking, coconut water is a good promoter for tissue culture because of containing growth substances. In addition, the coconut tree shape is beautiful, and the coconut tree is an excellent tree species for greening and beautifying the environment in tropical regions.

Coconut is a woody crop with heat generation for many years, and the growth period can be roughly divided into a juvenile period, an initial flowering and early fruiting period, a full flowering and full fruiting period and an aging period. Plants in different growth periods require different nutritional conditions. The coconut young stage includes coconut germination stage, coconut seedling transplanting early stage and coconut seedling transplanting later stage, and when the main nutrients of coconut in seedling transplanting early stage are provided by coconut, it needs external nutrient supply. When the coconut seedlings are transplanted to the field, the nutrition of the coconut is almost exhausted, and the coconut can normally grow only by external nutrition supply. From the germination of the coconut to the seedling stage of the coconut, the growth and development of the root system of the coconut are very important, especially in the middle and later stages of young coconut trees with almost exhausted coconut. In the breeding of coconut seedlings, during the period of breeding a part of coconuts, the growth and development of roots are stagnated, the cocoons grow slowly, and the cocoons are damaged by diseases and insects and are rotten, so that the problems of the cocoons, such as the rapid reduction of the nutrient absorption capacity of the cocoons to the outside and the coconuts, the shortage of the cocoons, the reduction of the disease resistance capacity, the occurrence of physiological yellowing of the cocoons, the withering of the cocoons Miao Xinrui, even the death of the cocoons and the like are caused directly or indirectly, and therefore, a proper liquid fertilizer needs to be applied to the cocoons in the young age period to promote the growth of the cocoons.

The liquid fertilizer is a fertilizer which has no certain shape and is in a flowing state, and has the advantages of low production cost and convenience in irrigation and fertilization. The liquid fertilizer has rich nutrients and a multifunctional effect, can meet various requirements of coconut seedlings on nutrients, has high solubility, can be quickly diluted, can be used for water and fertilizer integration, and effectively saves time and labor input; the growth speed of coconut seedlings can be increased, and the robust growth of the coconut seedlings in the seedling stage is promoted; promoting the development and growth of the root system of young coconut trees, accelerating the regression, recovery and green turning of physiological yellowing of young coconut trees, and improving the capability of resisting diseases and insect pests. Is an optimized liquid fertilizer for protecting healthy and fast growth of young coconut trees.
