High-yield nutritious fertilizer for fruit crops

Abstract

The invention provides high-yield nutritious fertilizer for fruit crops. The high-yield nutritious fertilizer for the fruit crops is prepared from components by weight as follows: 1-8 parts of urea, 0.2-4 parts of phosphoric acid, 0.5-7 parts of potassium hydroxide, 0.3-0.7 part of calcium phosphate and 0.2-0.5 parts of magnesium sulfate, and further contains ferrous sulfate, zinc sulfate, borax,silicon dioxide and organic matter. Products are prepared from the fertilizer in accordance with various nutrients needed by crops in each growth period, all the products in the period are combined toform a fertilizer set which is supplied once, or the fertilizer in all growth periods is integrated to form matched nutrient fertilizer for the whole growth and development period of the crops. Not only are problems of fertilization blindness and randomness of farmers solved, but also nutrient deficiency and insufficient nutrient supply of the crops in the growth and development periods can be avoided, and the fertilizer is effort-saving, time-saving, labor-saving, convenient, affordable and scientific.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a fertilizer for high-yield nutrition of fruit crops. Background technique [0002] The normal growth and development of crops and the formation of yield require a variety of nutrient elements, and there is a balanced proportional relationship between various nutrient elements. The entire life cycle of crops is divided into many key stages. These key stages need to supplement a large amount of nutrients, and the absorption of nutrients is also different in each growth stage. The life cycle of fruit crops is mainly divided into germination period, budding period, full bloom period, after flower withering, young fruit development period, strong fruit period, color change period, before fruit picking, after harvesting, in order to ensure the growth and development of crops There is sufficient nutrient supply in all critical periods, and nutritional elements need to be supplemented according to their...

AI Technical Summary

Problems solved by technology

[0004] In recent years, extra-root fertilization has been widely used in agricultural production, but due to the lack of agricultural knowledge of farmers, there is blindness and randomness in fertilization, because they do not understand the principles of crop growth, and do not understand the crops at a certain growth stage. What nutrients should be supplemented, what fertilizer should be applied, and how much fertilizer should be applied. Supplementing unnecessary nutrients during the growth stage of crops or supplementing too little or too much nutrients will make external fertilization less effective and difficult to achieve the desired purpose.
