Fertilizer composition and application thereof

Abstract

The invention discloses a fertilizer composition. The fertilizer composition is prepared from calcium aspartate and rhamnolipid, wherein the weight ratio of the calcium aspartate to the rhamnolipid is0.5:1-50:1. The fertilizer composition has the advantages that roots and tubers of root and tuber crops are promoted to become large and thick, the number of larger roots and tubers is large, the number of smaller roots and tubers is small, the product quality of the crops is improved, the yield of the crops is increased, meanwhile, the content of beta-carotene and the content of mineral substances (calcium) are also increased, and in addition, the effect the same as or even better than that of a chemical fertilizer can be achieved, but the soil contamination caused by using the chemical fertilizer is avoided; and macroelements, medium elements and microelements necessary for the growth of the crops are also added, so that the element deficiency symptoms of the crops are prevented and treated, the growth and development of the crops are facilitated, and the yield of the crops is increased.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a fertilizer composition and its application. Background technique [0002] With the continuous improvement of people's quality of life, chronic diseases caused by obesity caused by excessive animal food intake are on the rise year by year, such as hyperlipidemia, hypertension, coronary heart disease, diabetes, fatty liver, etc. These sounded the alarm to people, and now people gradually realize the importance of dietary fiber. The root tuber food is rich in starch, dietary fiber and a variety of vitamins and minerals. These foods are rich in nutritional value and have certain effects on the prevention of chronic diseases such as hyperlipidemia, hypertension, coronary heart disease, and diabetes. Moreover, people have higher requirements on the external quality and internal quality of commodities. It is necessary to increase production and income while ensuring the intrinsic and ext...

Problems solved by technology

[0004] In order to solve the problem of soil chemical fertilizer pollution caused by the long-term use of chemical fertilizers in the prior art, the present invention provides a method that can promote the hypertrophy of the roots of root crops, reduce the number of small rhizomes, improve product quality and yield, and especially improve the quality and yield of root crops. High-efficiency, non-polluting fertilizer composition containing calcium aspartate and rhamnolipid with medium β-carotene and mineral (calcium) content and its application
