Problems solved by technology

[0004] The plant nutrient solution directly acts on the root soil of the plant, which often has the problem of serious loss of nutrients and low effective utilization rate
And because most of the plant nutrients are composed of chemical reagents, and there are many mineral elements, long-term use will cause soil compaction and fertility decline, resulting in plant production reduction or plant poisoning.

Abstract

The invention relates to the technical field of biotechnology and plant nutrition, in particular to a plant nutrient solution and its preparation and application method. The plant nutrient solution comprises the following components and parts by weight: 20-50 parts of black rice anthocyanin crude extract, 30-100 parts of corn steep liquor, 10-30 parts of potassium polyacrylate, 5-10 parts of aloe vera gel and 50 parts of water ~120 servings. The plant nutrient solution of the invention can significantly promote the development of plant roots, promote the overall healthy development of plants, and increase the number of plant fruits and the ability to resist diseases and insect pests. The plant nutrient solution of the invention can also be applied to plant grafting, and has the functions of promoting rapid wound healing and improving the survival rate of grafting.

Description

technical field [0001] The invention relates to the technical field of biotechnology and plant nutrition, in particular to a plant nutrient solution and its preparation and application method. Background technique [0002] Plant nutrition plays a key role in plant growth. At present, scientists have found that there are 17 kinds of elements necessary for plants by using plant hydroculture technology, which can be divided into two categories: macronutrients and micronutrients. Macroelements are elements that plants require a large amount, and their content in plants accounts for more than 0.1% of dry weight, including nine kinds of C, H, O, N, P, K, Ca, Mg, and S; trace elements are plant There are 8 kinds of elements that require less amount, and their content in the plant body accounts for less than 0.0% of the dry weight, including Mo, Cu, Zn, Mn, Fe, B, Cl, and Ni. Among them, C, H, and O are mainly obtained from air and water, while the other 14 elements are mainly obt...
