Problems solved by technology

However, due to the easy formation of antagonism between trace elements, they cannot be effectively absorbed by plants; at the same time, due to the nitrogen in the compound fertilizer under the action of digestive bacteria and urease, a series of side effects occur in the soil, resulting in the loss of nitrogen and soil pollution

Abstract

The invention discloses an instant water-soluble fertilizer, which is mainly prepared from the following raw materials: urea, potassium dihydrogen phosphate, ammonium polyphosphate, potassium nitrate, trace elements in chelated state, anti-caking agent, surfactant, disintegrant antidote. The instant water-soluble fertilizer of the present invention can quickly dissolve, promote the rapid absorption of nutrients by plants, improve the utilization rate of nutrients, improve the quality and yield of plants, and can avoid soil pollution after application, and can meet the needs of drip irrigation and micro-spraying The preparation method of the instant water-soluble fertilizer of the present invention has easy-to-obtain raw materials, simple operation, and is easy to implement, and the obtained instant water-soluble fertilizer has stable and reliable quality, which is beneficial to the full absorption of each nutrient element by plants and greatly improves the plant yield .

Description

technical field [0001] The invention belongs to the technical field of agricultural chemical fertilizers, in particular to an instant water-soluble fertilizer containing a large amount of elements and a preparation method thereof. [0002] technical background [0003] Fertilizer, as the food that supplies the nutrients needed by plants, has become an important basis for the development of modern agriculture. At present, compound granular fertilizers based on N, P, and K have become the mainstream, and some fertilizers are also added with trace elements or multiple functional elements. These fertilizers are nutritious. However, due to the easy formation of antagonism between trace elements, they cannot be effectively absorbed by plants; at the same time, due to the nitrogen in the compound fertilizer under the action of digestive bacteria and urease, a series of side effects occur in the soil, resulting in the loss of nitrogen and soil pollution.
