Magnesium-rich leaf nutrient sprayed onto fruit trees before fruit setting

Abstract

The invention relates to the field of microelement fertilizer study, in particular to a magnesium-rich leaf nutrient sprayed onto fruit trees before fruit setting. The magnesium-rich leaf nutrient is prepared from 45 to 55 parts of water-soluble magnesium fertilizers, 20 to 25 parts of sugar alcohol magnesium, 1 to 2 parts of rare earth, 3 to 5 parts of sugar powder, 1 to 3 parts of amino acid, 1 to 3 parts of alginic acid, 5 to 10 parts of plant growth promoters, 3 to 5 parts of surfactants and 5 to 10 parts of auxiliary trace elements. The instant magnesium fertilizers and surfactants are contained, so that both the timeliness and the absorption rate are considered; the magnesium-rich leaf nutrient is sprayed onto the fruit tree plants in different stages; the fruit development is promoted; the yield is improved; the insect pest is reduced. The magnesium-rich leaf nutrient has the beneficial effects that the problem of magnesium lacking in the fruit planting process can be mainly solved; the magnesium-rich leaf nutrient is particularly suitable for being used in sand soil and acid soil; a recipe of combining easy-to-dissolve magnesium fertilizers and surfactants is used; the permeability of the leaf fertilizer is improved; the absorption rate is improved; the growth regulating agent is contained, so that the plant cell cracking is promoted; the plant yield is improved; the recipe is reasonable; the yield increase effect is obvious; in addition, the fruit quality is improved.

Description

technical field [0001] The invention relates to the field of trace fertilizer research, in particular to a magnesium-rich foliar nutrient sprayed before fruiting of fruit trees. Background technique [0002] 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 stimulate the activity of glucokinase, fructokinase and phosphoglucomutase related to carbohydrate metabolism; it is also an activator of DNA polymerase, which can promote the synthesis of DNA. In addition, magnesium is also related to fat metabolism, which can promote the conversion of acetic acid into acetyl-CoA, thereby accelerating the synthesis of fatty acids. Magnesium deficiency in plants will hinder the metabolism in the body, especially the development of young tissues and the maturity of seeds. Magnesium...

Problems solved by technology

[0005] The existing fruit tree fertilizers are all compound fertilizers, which contain a variety of trace elements, but have not been finely divided, and lack targeted supplements, resulting in some trace elements exceeding the actual needs of fruit trees, which will have a negative impact on the quality of the fruit. How to use them accurately and efficiently Trace elements are a topic worth studying
