Rare earth formulated fertilizer special for grapes and preparing method and application thereof

Abstract

The invention discloses a rare earth formulated fertilizer special for grapes and a preparing method and application thereof. A basic nutrition fertilizer containing nitrogen, phosphorus and potassiumis involved and comprises brassinolide, calcium nitrate, manganese sulfate, zinc sulfate, hydrophilic nanometer titanium dioxide and lanthanum nitrate. After the special rare earth formulated fertilizer is applied to a grape field, the yield is high, and fruits are large in size, delicious and rich in fruity aroma; all raw materials have a synergistic effect, the fertilizer efficiency and nutrition balance degree of the fertilizer are effectively improved, the water retentivity and nutrition balance degree of soil can also be improved, sufficient nutrients are supplied to the grape field, theeffects of improving the grape quality and increasing the grape yield are both good, and borne grape fruits are large in size, full, sweet in mouthfeel, and high in yield; the cold resistance, drought resistance and disease resistance of the grapes can be enhanced, and the ecological effect is good; thorough release of the fertilizer can be guaranteed under a slow-release condition.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special rare earth formula fertilizer for grapes and its preparation method and application. Background technique [0002] Grape is a deciduous vine of the genus Vitis. The fruit is round or oval, and the color varies with the variety. Humans have been cultivating such fruit trees a long time ago, accounting for almost a quarter of the world's fruit production. Grapes are mainly distributed in Northeast my country, North China, Northwest China and Huanghuaihai region. The nutritional value of grapes is very high, and grape juice is known as "vegetable milk" by scientists. The sugar content of grapes is very high, as high as 10-30%. Most of the sugar contained in grapes is glucose that is easily absorbed by the human body. Therefore, when the human body has hypoglycemia, drinking grape juice in time can quickly relieve symptoms ease. The various fruit acids ...

AI Technical Summary

Problems solved by technology

[0004] At present, grape fertilizers not only seriously damage the soil, but also the grapes grown have poor taste, poor quality, poor storability, and poor quick-acting and long-acting fertilizers; at the same time, it is easy to destroy the acid-base balance of the land, resulting in an imbalance in the proportion of soil nutrients , the salinization trend of the land is increasing, and physiological diseases often occur

Grape fertilization has been using a single fertilizer mixed fertilization method for a long time. On the one hand, this fertilization method is not conducive to the growth of grape fruit trees. On the other hand, the various nutrients needed for grape growth cannot keep up with it in time, so a variety of chemical fertilizers must be used. For mixed use, the production cost is relatively high
