Novel foliage fertilizer

Abstract

The invention provides a novel foliage fertilizer. The novel foliage fertilizer is prepared from the following components in parts by mass: 6-8 parts of EDTA calcium, 3-5 parts of wood vinegar, 1-3 parts of urea, 0.15-0.30 part of monopotassium phosphate, 0.5-1.0 part of potassium sulfate, 1.0-2.0 parts of ferrous sulfate, 0.05-0.10 part of magnesium sulfate, 1.0-2.0 parts of sodium naphthalene-1-acetate and the balance of water. The foliage fertilizer has the advantages that the content of metal cadmium in crops can be well decreased while the yield is increased; and EDTA calcium and basic nutrient elements required by plants are added, so that the effects of increasing the yield of rice by 9.29-20.17% and increasing the yield of wheat by 9.74-19.67% are achieved, meanwhile, the content of cadmium in brown rice can be decreased by 31.28-64.14%, the content of cadmium in wheat grains can be decreased by 31.61-62.96%, and therefore the quality of the plants after application of the foliage fertilizer in a cadmium-contaminated area can be further improved, the quality of products in the area can be further improved, and the purposes of increasing the yield and reducing cadmium can beachieved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a novel foliage fertilizer. Background technique [0002] Plants absorb nutrients mainly through two ways: one is to obtain the required nutrients directly from the soil through the root system, and the other is to directly absorb the required nutrients through the leaves. Most terrestrial plants rely on their roots to absorb nutrients, but the leaves of plants can also absorb exogenous substances, such as gases, nutrients, pesticides, etc. While absorbing water, the leaves can absorb nutrients into the plant like roots go. Leaves are the most important extra-root vegetative organs of plants, and foliar nutrition refers to the absorption and utilization of various nutrients by plants through the surface of leaves. When different forms and types of nutrients are sprayed on the leaves of crops, the nutrient utilization effect absorbed by the crops on the leaves is the same as...

AI Technical Summary

Problems solved by technology

It is easily transferred from the soil to plants, thus threatening human health and plant growth and development. Foliar fertilization technology and the application of foliar fertilizer are a major breakthrough in people's understanding of the law of plant foliar nutrient absorption. Foliar fertilization breaks the root of the soil. The traditional method of fertilization. At present, there are many different varieties of foliar fertilizers in China. However, most of the existing foliar fertilizers are of a single variety, and can only achieve the effect of increasing production. When applied in cadmium-contaminated areas, they cannot reduce plant growth. Content of heavy metal cadmium

It may even promote the uptake of cadmium by the plant, resulting in an increase in cadmium levels in the edible part
