Problems solved by technology

[0003] It can be seen that although nanomaterials have the functions of improving fertilizer utilization, promoting crop growth, and improving the quality of agricultural products, their toxicity is extremely harmful to the preparation and application operators and animals in the environment, so the preparation and application protection requirements are relatively high. , and the preparation is difficult and inefficient, and the prospect of agricultural application is severely limited

Abstract

The invention discloses an application of solid micron powder insoluble in water. The application of the solid micron powder insoluble in water includes that firstly, the powder and plant seeds are subjected to seed dressing; and secondly, the powder and a fertilizer of a plant are mixed to be applied as a base fertilizer or topdressing. The grain size of the powder ranges from 2.5 mu m to 50 mu m; and the powder is selected from at least one of sedimentary rock, volcanic rock, metamorphic rock, calcium carbonate, calcium sulfate, magnesium carbonate, ferric oxide, ferroferric oxide, iron pyrite, haematite, magnetite, wood coal, graphite, carbon black, brown coal, rock phosphate, zeolite, attapulgite, mica, zinc oxide, cupric oxide, quartz sand and manganese dioxide. The solid micron powder insoluble in water is applied to planting and growing processes of the plant, so that the plant growth can be promoted, the yield is increased, and the product quality is improved.

Description

technical field [0001] The invention relates to the use of a water-insoluble solid micron powder. Background technique [0002] The application of nanotechnology in the field of agriculture began in the late 1990s. Research involving nano-SiO 2 , fertilizer nano-coating materials, nano-rare earth plant growth regulators, etc., among which Wang Lijun discussed the development of nano-SiO 2 Protect plants from pathogens and improve plant disease resistance. Indeed, the particle-scale correlation of toxic effects on organisms is a crucial indicator. Through research, scientists know that nanoparticles deposit more in the lungs than larger particles, and also penetrate deeper into lung tissue. The results of an epidemiological study conducted in the United States for more than 20 years showed that, relative to 10 μm, every 100 μg.m increase of 2.5 μm in the air -3 , the mortality rate of lung cancer and cardiovascular disease in the population increases by 12% to 19%; -3 ,...
