Embodiment 1

[0014] A kind of loss-controlling and controlled-release fertilizer of the present invention is applicable to general soil, and it is made up of urea, monoammonium phosphate, ammonium chloride, potassium chloride and ammonium bicarbonate, and this urea, monoammonium phosphate, ammonium chloride, chloride The ratio of potassium and ammonium bicarbonate is 34.15:31.71:19.51:4.88:9.76.

[0015] Loss Control: Control the loss of fertilizer. It mainly uses the effect of the wrapping film on the outside of the fertilizer, and the configuration according to the above formula will form a wrapping film on the outside of the fertilizer.

[0016] Controlled Release: Controlled release of fertilizer. Whether it is economic crops or crops in different periods, there are certain differences in the demand for nitrogen, phosphorus and potassium fertilizers, and different economic crops and crops have different requirements for fertilizers (mainly three stages: juvenile stage (basic fertiliz...

Embodiment 2

[0019] In the paddy field of 10 mus of land, the effect contrast experiment of product common compound fertilizer Yukong fertilization of the present invention is carried out, and contrast result is as shown in table 1 below.

Abstract

The invention relates to a loss-control controlled-release fertilizer which is composed of urea, monoammonium phosphate, ammonium chloride, potassium chloride and ammonium bicarbonate. When the fertilizer is in use, an auxiliary material attapulgite is needed. The ratio of the attapulgite, urea, monoammonium phosphate, ammonium chloride, potassium chloride and ammonium bicarbonate is 6:34.15:31.71:19.51:4.88:9.76. The fertilizer is reasonable in preparation, can supply sufficient nutritive elements to soil in time, enhances the utilization ratio of the fertilizer on crops, reduces the fertilizer loss in the use process, and has higher actions on social permanent and steady development in the aspects of environment protection and energy saving.

Description

technical field [0001] The invention relates to a chemical fertilizer, in particular to a loss-controlled and controlled-release fertilizer. Background technique [0002] The nutrients in the soil will be lost due to various reasons, which is not good for plant growth. How to replenish the nutrients in the soil in time and effectively maintain the content has become the current research direction. Therefore, the development of a controlled loss and controlled release fertilizer has a good effect. significance. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a controlled-loss and controlled-release fertilizer to achieve the purpose of improving the utilization rate of the fertilizer on crops and reducing the loss of the fertilizer during use. [0004] A kind of loss-controlling and controlled-release fertilizer of the present invention, it is made up of urea, monoammonium phosphate, ammonium chlorid...
