Magnesium-rich foliar nutrient and application thereof in tea planting

Abstract

The invention relates to the field of microelement fertilizer research and particularly discloses a magnesium-rich foliar nutrient and application thereof in tea planting. The magnesium-rich foliar nutrient is prepared from the following raw materials in parts by weight: 65-72 parts of a water-soluble magnesium fertilizer, 5-10 parts of chelating magnesium, 2-4 parts of fulvic acid, 1-3 parts of nucleotide, 0-1 part of rare earth, 5-12 parts of a plant growth accelerator, 5-10 parts of accessory microelements, 3-5 parts of a surfactant, an instant magnesium fertilizer and a surfactant. The timeliness and the absorptivity are considered, and the magnesium-rich foliar nutrient is mainly applied to the aspect of tea tree planting. The magnesium-rich foliar nutrient has the beneficial effects that the problem of magnesium deficiency in planting process of commercial crops, such as tea trees is mainly solved; the magnesium-rich foliar nutrient is especially suitable for sandy soil and acid soil; absorption of the foliar nutrient is promoted by adopting the surfactant and the nutritional ingredients are high in permeability and absorptivity; the magnesium-rich foliar nutrient contains a production regulator, so that plant cell division is promoted, the yield of plants is improved and the cooperation effect of a growth regulator and a magnesium fertilizer is better; and the formula is reasonable, the yield-increasing effect is obvious and the content of effective ingredients in the tea is improved.

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 tea plantation. 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 can stimulat...

Problems solved by technology

[0006] Existing plant 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 plants and adversely affecting the quality of plants; and during the application of foliar fertilizers, Due to weak nutrient penetration and low absorption rate, how to use trace elements accurately and efficiently is a topic worth studying
