Problems solved by technology

[0005] The present invention aims to improve on the basis of CN98114512.4, CN01131851.1, CN200410013758.5, and develop a selenium-rich plant drought-resistant agent to solve the problem of selenium deficiency in plants, low temperature, continuous rain, low-lying and humid land, and paddy field improvement during spring sowing. In dry fields and covered with plastic film, the disease resistance of seeds is weakened, and they are easy to infect mold, causing the seeds to rot. In addition, the production process of the existing super absorbent agent is relatively complicated, and it needs to be reacted under nitrogen conditions, and the cost is relatively high.

Abstract

An ultra-strong water absorbent for agricultural purpose is prepared from bentone, acrylamide, acrylic acid and urea through radiated copolymerization. A Se-enriched drought resisting agent for plants is prepared from said ultra-strong water absorbent, Se, plant growth regulator, oxygen releasing agent, antibacterial antiseptic, cold resisting agent, penetrant, trace elements and additive.

Description

technical field [0001] The invention belongs to the technical field of medicinal fertilizers, and relates to a super water-absorbing agent, a preparation method thereof and a water-retaining agent for drought-resistant cultivation of selenium-enriched plants using it as a raw material. Background technique [0002] Years of spring droughts in northern China have caused rivers to dry up, groundwater levels to drop, and water resources to dwindle. China is a big water-poor country, and its per capita water resources ranks 109th in the world, accounting for a quarter of the world's per capita possession. my country's water-deficient area amounts to more than 580,000 square kilometers. [0003] There are more than 800 million mu of land threatened by drought in northern my country. Every year, a lot of cultivated land is barren due to spring drought. China loses 30 billion kilograms of grain every year due to drought, causing great economic losses. At the same time, my country...
