Selenium-enriched plant nutrient solution and preparation method thereof

Abstract

The invention relates to a selenium-enriched plant nutrient solution and a preparation method thereof. The selenium-enriched plant nutrient solution comprises a component A and a component B, whereinthe component A comprises the following components in percentage by weight: 20-32% of Chinese yew branches and leaves, 25-28% of pine needles of Pinus massoniana, 25-28% of garlic stems, 6-8% of Zanthoxylum armatum leaves and 12-16% of industrial sodium selenite powder, and the component B comprises the following components in percentage by weight: 13-30% of medical stone, 22-25% of germanite, 8-10% of tourmaline, 23-25% of volcanic rock, 8-10% of verdelite, 1-3% of rare earth terbium, 1-3% of rare earth ytterbium, 4-6% of light rare earth and 3-5% of neodymium iron boron. The selenium-enriched plant nutrient solution has obvious effect in application practice, breaks through the limitation of using organic matters and organic fertilizers to improve soil in the traditional method, and usesa chemical principle to improve the soil. The method is simple and has quick effect. The product is tried and popularized in Chengdu, Deyang, Zizhong, Guang 'an and other cities in Sichuan Province,increases the yield by 5-30%, improves the product quality and improves the acid-base balance of the soil to achieve a very good effect.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, in particular to a selenium-enriched plant nutrient solution and a preparation method thereof. Background technique [0002] People's Daily Online reported: In 2015, China's total grain output reached 621.435 million tons, but it could not meet actual needs, and the gap was increasing day by day. A large amount of grain had to be imported every year. Qian Keming, chief economist of the Ministry of Agriculture, said at the National Two Sessions: my country's annual chemical fertilizer consumption ranks first in the world, accounting for one-third of the world's total, equivalent to the sum of the United States and India. Excessive application of chemical fertilizers causes the degradation of cultivated land and causes environmental pollution: (1) Water pollution: 90% of urban groundwater in my country is polluted by organic and inorganic toxic and harmful pollutants, and over 100 million ...

Problems solved by technology

[0003] Aiming at the problem that soil pollution is serious and food safety is threatened, the invention provides a selenium-enriched plant nutrient solution and a preparation method thereof, which can act on plant cells and promote the metabolism of plant cells when applied in soil improvement, and has The effect of adjusting the pH in plants can reduce the dispersion of protoplast colloids, which is beneficial to the normal metabolism of plants, has the function of increasing phosphorus fertilizer, can enhance the drought resistance and cold resistance of plants, promote early flowering and early maturity of plants, and can enhance photosynthesis Function and promote the metabolism and synthesis of carbohydrates, which can not only increase the yield, but also improve product quality, neutralize the acidity in the soil, and improve the acid-base balance of the soil
