Description
Technical Field
The invention belongs to the technical field of crop nutrition enhancement, and particularly relates to a method for enhancing vacuum water permeability nutrition of breast breaking seeds.
Background
The 'recessive hunger' refers to the hunger symptom of the body caused by the unbalanced nutrition or the lack of certain vitamin and mineral substances necessary for the human body and the excessive intake of other nutrient components, thereby generating the hidden nutrient requirement. The most common "recessive starvation" includes iron deficiency, iodine deficiency, zinc deficiency, vitamin and mineral deficiency. The micronutrients allow the body to grow normally and ensure that the body can perform important physiological functions. With the improvement of living standard and the popularization of health care knowledge, the problem of unbalanced intake of micronutrients has been more and more emphasized.
The crop nutrition strengthening way directly solves the problem of micronutrient deficiency from the aspect of crop breeding, and is a simple, convenient, economic and effective way for preventing and improving the micronutrient deficiency of people and the occurrence of related diseases. From a market perspective, nutrition-enhanced products obtained through natural agricultural production are more likely to be appreciated by consumers.
The existing crop nutrition enhancement is mainly implemented by cultivating and enhancing crop breeding after adding nutrient substances into soil, cultivating and enhancing crop breeding by adding nutrient substances into fertilizers, cultivating and enhancing crop breeding by adding nutrient substances into irrigation water and carrying out seed nutrition enhancement in a biological breeding mode. However, the strengthening method of adding nutrients to soil, fertilizers and irrigation water has large nutrient loss and high nutrient adding cost, and the biological breeding has long nutrient strengthening period, so that a new nutrient-strengthened crop variety suitable for cultivation cannot be obtained quickly.
