Stress-resistant active fertilizer special for rice

Abstract

The invention provides a stress-resistant active synergistic fertilizer special for rice, which comprises a fertilizer and a fertilizer auxiliary agent, and the fertilizer auxiliary agent comprises modified diatomite, a stress-resistant active factor for promoting crop growth and a high polymer material. According to the efficient environment-friendly fertilizer auxiliary agent replacing the plantregulator and the preparation method of the special fertilizer for the rice, the utilization rate of the fertilizer is increased, meanwhile, root growth of the rice in the seedling stage can be promoted, and absorption of beneficial medium and trace elements by the rice is promoted; the stress resistance effects such as salt resistance, cold resistance and drought resistance of rice are improved,the soil structure is improved, the soil microenvironment is adjusted, the risk that harmful substances such as heavy metals enter edible parts of crops is reduced, and the crop quality is improved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a special fertilizer for stress-resistant active rice. Background technique [0002] Recent studies have shown that there is a law of diminishing returns in the relationship between fertilization and yield: the more fertilization, the lower the utilization rate of fertilizer, the less the yield of crops increased per unit of fertilization, and excessive fertilization may even cause yield reduction and pollute the environment. The main reasons are: 1. Low technical content of fertilizer products; 2. Low level of fertilization technology; 3. Soil compaction, poor water and fertilizer retention; 4. Crops are affected by adverse environments such as saline-alkali, cold, drought, and disease, and the root growth is weak , affecting the absorption and utilization of nutrients.

Problems solved by technology

[0002] Research in recent years has shown that there is a law of diminishing returns in the relationship between fertilization and yield: the more fertilization, the lower the fertilizer utilization rate, the lower the yield of crops increased by the unit of fertilization, and excessive fertilization may even cause production reduction and pollute the environment

The main reasons are: 1. Low technical content of fertilizer products; 2. Low level of fertilization technology; 3. Soil compaction, poor water and fertilizer retention; 4. Crops are affected by adverse environments such as saline-alkali, cold, drought, and disease, and the root growth is weak , affecting the uptake and utilization of nutrients

[0003] Excessive use of fertilizers, some nutrients such as nitrogen and phosphorus that are not used by crops leak into the groundwater, causing groundwater pollution, such as groundwater nitrite exceeding the standard, which seriously threatens the safety of humans and animals; part of it enters the surface water through surface runoff, resulting in surface water enrichment Nutritization; many toxic and harmful substances such as: heavy metals seep into the soil, causing environmental pollution

Soil salinization, compaction, and bad weather cause ecological deterioration, resulting in a decline in the quality of cultivated land, affecting the normal growth and quality of crops

Therefore, there is an urgent need to study a kind of stress-resistant active fertilizer, which can not only increase the production of chemical fertilizers, but also overcome the deterioration of soil physical and chemical properties and soil pollution caused by the long-term application of chemical fertilizers, so as to achieve the environmental friendliness of improving soil, increasing crop production and improving quality. type fertilizer

[0004] At present, plant growth regulators such as sodium nitrophenolate and gibberellin are added to fertilizer varieties on the market. The purpose is to improve the stress resistance of crops through the action of regulators; but there are no standard restrictions, causing market confusion and regulators. Abuse, affecting the quality and safety of crops
