Selenium-rich peanut fertilizer

Abstract

The invention discloses selenium-rich peanut fertilizer and belongs to the field of fertilizer. The selenium-rich peanut fertilizer comprises, by weight, 500 parts of concentrated molasses ferment powder, 70 parts of citric acid, 10 parts of urea, 2 parts of sodium selenite, 5 parts of a growth conditioning agent and 9 parts of trace elements. The selenium-rich peanut fertilizer contains a plurality of trace elements such as zinc, calcium, iron, magnesium and molybdenum needed by crops, can promote peanut development, contains sodium selenite, is free of sodium selenate and prevents damage to producer and consumer health.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a selenium-enriched peanut fertilizer. Background technique [0002] The natural element selenium is associated with the chemical element chromium and cannot be used directly because chromium is a highly toxic substance. Selenium is an essential micronutrient for animals and humans. The recommended daily intake by the International Selenium Society is 60-400 μg, and the recommended daily intake by the Chinese Nutrition Society is 50-200 μg. According to my country's nutritional survey, the daily intake of selenium for adults is only 26-32 μg. Therefore, selenium malnutrition is a common problem in our population. my country's selenium-deficient soil accounts for 72% of the country's land area, and the selenium-deficient population reaches more than 100 million. Many endemic high-incidence diseases in my country, such as Keshan disease, Kaschin-Beck disease, cancer, cardiovascular a...

Problems solved by technology

Quality nutrition is the latest development in current plant nutrition research, and selenium is the latest focus of plant nutrition research (Academician Li Zhensheng, National Natural Science Foundation of China in November 1999, the 21st Century Core Scientific Issues Symposium). In the past, multi-component compound trace element preparations have been It has obvious effects and has entered industrialization. Products such as foliar fertilizers have begun to take shape. There is no selenium-enriched biological preparation in China, which cannot meet the needs of selenium-enriched agricultural products.
