Problems solved by technology

[0003] At present, compound fertilizers containing boron and magnesium elements are prepared by adding boron and magnesium inorganic salts or oxides to nitrogen, phosphorus and potassium compound fertilizers. Due to the solidification of the soil and the antagonism between ions, the utilization rate of trace elements is low.

Abstract

A humic acid, boron and magnesium chelated insecticide-fertilizer comprises the following components in parts by weight: 20-30 parts of urea, 10-15 parts of diammonium hydrogen phosphate, 10-15 parts of potassium sulfate, 22-25 parts of humic acid, 1-2 parts of ammonium borate, 1-2 parts of magnesium sulfate, 1-1.5 parts of benthiavalicarb-isopropyl and 0.5-1 part of dinotefuran. Ammonium borate, magnesium sulfate and humic acid are added into a reactor and then added with water to react at 80-90 DEG C, as a result, a boron and magnesium chelation fertilizer solution is prepared; benthiavalicarb-isopropyl and dinotefuran are added into the boron and magnesium chelation fertilizer solution to obtain a pesticide chelation fertilizer mixed solution; urea, potassium sulfate and diammonium phosphate are mixed and added into a pelletizer and made into pellets after being sprayed with the pesticide chelation mixed solution, so as to the humic acid, boron and magnesium chelated insecticide-fertilizer. The humic acid, boron and magnesium chelated insecticide-fertilizer is rich in nutrition and high in utilization ratio of elements B and Mg, and not only can provide required nutrition to plants, but also has effect of insect killing, thereby effectively improving the yield of crop.

Description

technical field [0001] The invention relates to a humic acid chelated boron and magnesium medicinal fertilizer and a preparation method thereof. Background technique [0002] Fertilizers can provide the necessary nutrients for plants. In addition to nitrogen, phosphorus and potassium macronutrient fertilizers, medium and trace elements also play a vital role in the growth of crops. Boron is an essential nutrient element for cell division, pollination and fruit setting of crops. It participates in the transportation and metabolism of sugar in crops, and especially has a symbiotic and fixed effect on nitrogen in all crops. Magnesium is a component of chlorophyll. When magnesium is deficient, the synthesis of chlorophyll in plants is hindered. Magnesium is an activator of ribulose diphosphate carboxylase, which can promote the assimilation of carbon dioxide by plants; magnesium ions can stimulate the activities of glucokinase, fructokinase and phosphoglucomutase related to car...
