Problems solved by technology

[0002] my country is a large agricultural country, and the main crops are rice and wheat. For a long time, while pursuing high yield of rice, a large amount of pesticides and chemical fertilizers have been used, which has made the land compacted, low in fertility, and made the food contain some substances that are not conducive to human health. , when people are pursuing the needs of food safety and nutrition, the current agricultural products obviously cannot meet the needs of the market
Therefore, more and more organic rice is planted, but most of the traditional organic rice planting methods use organic manure or farmyard manure as rice growth nutrients, but due to the nitrogen, phosphorus and potassium contained in this natural farmyard manure or organic manure Other rice essential elements are very few, resulting in insufficient nutrient supply when rice grows, so there will be problems such as low yield, poor quality, and lack of trace elements

Abstract

The invention discloses an organic long-acting multi-element fertilizer for rice. The long-acting multi-element fertilizer comprises slowly-released multi-element particles for slowly releasing elements for rice growing, and soft materials for adhering the slowly-released multi-element particles, wherein the mass ratio of the slowly-released multi-element particles to the soft materials is (70-111): (76-139). According to the organic long-acting multi-element fertilizer for the rice, different nutritional components can be supplied to the rice in different growing stages for a long time; the slowly-released multi-element particles can slowly release the nutritional components and meets the demand of the rice on a plurality of nutritional components; straw joints with the adsorbing propertyare capable of adsorbing a plurality of components and releasing, and moreover, bridges for connecting the components are formed.

Description

technical field [0001] The invention relates to the field of rice planting, in particular to a long-acting multi-element fertilizer for organic rice. Background technique [0002] my country is a large agricultural country, and the main crops are rice and wheat. For a long time, while pursuing high yield of rice, a large amount of pesticides and chemical fertilizers have been used, which has made the land compacted, low in fertility, and made the food contain some substances that are not conducive to human health. When people are pursuing the needs of food safety and nutrition, the current agricultural products obviously cannot meet the needs of the market. Therefore, more and more organic rice is planted, but most of the traditional organic rice planting methods use organic manure or farmyard manure as rice growth nutrients, but due to the nitrogen, phosphorus and potassium contained in this natural farmyard manure or organic manure Other rice essential elements are very fe...
