Magnesium-rich ground nutrient for fruit tree and application method thereof

Abstract

The invention relates to specifically relates to a magnesium-rich ground nutrient for a fruit tree and an application method thereof, belonging to the field of research on microelement fertilizer. The magnesium-rich ground nutrient comprises 60 to 70 parts of water-soluble magnesium fertilizer, 10 to 15 parts of slightly-soluble magnesium fertilizer, 3 to 5 parts of magnesium chelate, 1 to 3 parts of microbial fertilizer, 1 to 2 parts of rare earth, 1 to 3 parts of humic acid, 5 to 12 parts of a plant growth promoter and 5 to 10 parts of accessory microelements. The magnesium-rich ground nutrient contains both instant magnesium fertilizer and slow-release magnesium fertilizer, so the magnesium-rich ground nutrient has both fast action performance and long-acting performance; the magnesium-rich ground nutrient is uniformly sprayed onto the roots of a fruit tree in stages to promote growth of fruit, increase output and reduce insect diseases. The invention has the following beneficial effects: the magnesium-rich ground nutrient mainly overcomes the problem of magnesium shortage during plantation of the fruit tree and is especially applicable to sandy soil and acidic soil; with a combination of the easily-soluble magnesium fertilizer and the slow-release magnesium fertilizer, magnesium can be rapidly supplemented and magnesium fertilizer can be continuously provided in a period after application; the magnesium-rich ground nutrient contains the plant growth promoter and is thus capable of promoting division of plant cells and improving plant output; and the magnesium-rich ground nutrient is reasonable in formula and obvious in yield increasing effect and improves fruit quality.

Description

technical field [0001] The invention relates to the field of trace fertilizer research, in particular to a magnesium-rich fruit tree ground nutrient and an application method thereof. 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. Mag...

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
