Problems solved by technology

The normal growth and development of rice requires more nutrients, especially nitrogen, phosphorus, and potassium. Relying solely on soil supply cannot meet the needs of rice growth and development. At present, chemical fertilizers are often applied in multiple times. , to ensure sufficient nutrient supply for rice, but it is time-consuming and costly, and with the increase in nitrogen, phosphorus, and potassium application, a large number of nutrient elements are relatively enriched, which not only causes a decline in utilization rate, but also wastes resources and pollutes environment, with the excess of a large number of nutrients, the content of trace elements in the soil can no longer meet the demand, and the deficiency of trace elements in rice is also increasing. Although a variety of organic fertilizers have been developed at present, their nutrients are easy to volatilize and lose, and their fertilizer efficiency is fast. Long-lasting and prone to pests and diseases

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a special fertilizer for rice. Background technique [0002] Rice is native to tropical Asia, and after being widely planted in China, it gradually spread to all parts of the world. The rice grains produced by rice are called rice or rice after shelling. Nearly half of the world's population feeds on rice. Compared with other crops, The digestibility and absorption rate of nutrients contained in rice are relatively high, which is most suitable for the needs of the human body. The normal growth and development of rice requires more nutrients, especially nitrogen, phosphorus, and potassium. Relying solely on soil supply cannot meet the needs of rice growth and development. At present, chemical fertilizers are often applied in multiple times. , to ensure sufficient nutrient supply for rice, but it is time-consuming, laborious, and costly. With the increase of nitrogen, ...
