Magnesium-enriched foliar nutrient and application thereof in leaf vegetable planting

Abstract

The invention relates to the field of trace fertilizer, in particular to a magnesium-enriched foliar nutrient and application thereof in leaf vegetable planting. The magnesium-enriched foliar nutrient comprises 35-55 parts of water-soluble magnesium fertilizer, 20-40 parts of sugar alcohol magnesium, 2-4 parts of humic acid, 1-3 parts of nucleotide, 1-2 parts of jasmonic acid, 5-12 parts of plant growth promoter, 5-10 parts of auxiliary trace elements and 3-5 parts of surfactant. The magnesium-enriched foliar nutrient has the advantages that the magnesium-enriched foliar nutrient contains the fast-soluble magnesium fertilizer and the surfactant at the same time, considers both timeliness and absorption rate and is mainly applied to the leaf vegetable planting; the magnesium-enriched foliar nutrient is mainly used to solve the problem of magnesium shortage during the leaf vegetable planting and is especially applicable to sandy soil and acid soil; the surfactant is used to promote the absorption of the foliar nutrient, and high nutritional component permeability and high absorption rate are achieved; the magnesium needed by crops can be supplemented fast, chlorophyll synthesis is promoted, photosynthesis is enhanced evidently, crop nutritional growth is promoted, crop stress resistance is enhanced, and physiologic diseases such as leaf yellowing caused by the magnesium shortage can be prevented and relieved effectively.

Description

technical field [0001] The invention relates to the field of trace fertilizer research, in particular to a magnesium-rich foliar nutrient and its application in planting leafy vegetables. Background technique [0002] Trace element fertilizers are usually referred to as micro-fertilizers for short. Refers to fertilizers containing micronutrient elements, which are less absorbed and consumed by crops (compared to macronutrient fertilizers). Although crops require very little trace elements, they are equally important to crops like macro elements and cannot replace each other. The application of micro-fertilizers must be based on nitrogen, phosphorus, and potassium fertilizers to exert their fertilizer effects. [0003] Magnesium is one of the main components of chlorophyll in plants and is related to photosynthesis of plants. Magnesium is also an activator of ribulose diphosphate carboxylase, which can promote the assimilation of carbon dioxide by plants. Magnesium ions c...

Problems solved by technology

[0006] Existing vegetable foliar fertilizers are all compound fertilizers, which contain a variety of trace elements, but have not been finely divided, resulting in some trace elements exceeding the needs of vegetables and adversely affecting the quality of plants; , there are weak nutrient penetration and low absorption rate, how to use trace elements accurately and efficiently is a topic worth studying
