Environmentally friendly slow-release fertilizer having drought resisting function

Abstract

The invention discloses an environmentally friendly slow-release fertilizer having a drought resisting function which is prepared from 3,4-dimethyl pyrazole phosphate, urea, monoammonium phosphate, potassium chloride, potassium sulfate, lauryl alcohol ethoxy ammonium sulfate, polyacrylamide and sulphur. The environmentally friendly slow-release fertilizer utilizes the raw materials and the ratio thereof and a process, so that the long-acting fertilizer can have a longer fertilizer efficiency period and higher utilization rate and meanwhile can have the obvious effect on the aspects of water retention, drought resistance and the like.

Description

technical field [0001] The invention relates to a long-acting fertilizer, in particular to an environment-friendly long-acting fertilizer with a drought-resistant function. Background technique [0002] my country's Xinjiang, Gansu, Inner Mongolia, Shanxi, Shaanxi, northern Hebei and other areas of low-yielding fields generally have problems such as water shortage, soil desertification, high pH, ​​poor soil water retention capacity, and serious water and fertilizer leakage. The development of the local planting industry has also limited the agricultural productivity of the above-mentioned provinces on a large scale. After farmers fertilize and irrigate, the instant nutrient in the fertilizer dissolves in water, moves quickly underground with the water, and finally transfers out of the plow layer and becomes invalid. In particular, nitrate nitrogen moves the fastest, resulting in a shortage of water and fertilizer at the same time. The most important thing is that it pollutes...

Problems solved by technology

[0002] my country's Xinjiang, Gansu, Inner Mongolia, Shanxi, Shaanxi, northern Hebei and other areas of low-yielding fields generally have problems such as water shortage, soil desertification, high pH, ​​poor soil water retention capacity, and serious water and fertilizer leakage. The development of the local planting industry has also limited the agricultural productivity of the above-mentioned provinces on a large scale

After farmers fertilize and irrigate, the instant nutrient in the fertilizer dissolves in water, moves quickly underground with the water, and finally transfers out of the plow layer and becomes invalid. In particular, nitrate nitrogen moves the fastest, resulting in a shortage of water and fertilizer at the same time. The most important thing is that it pollutes groundwater and surface water and affects people's health

Farmers are forced to irrigate and topdress many times, causing huge waste, adding additional labor input, and polluting the environment at the same time

The high pH phenomenon in these areas, local to about 9.0, caused the phosphate ions applied to the fertilizer to combine with calcium ions and magnesium ions to quickly inactivate, resulting in the lack of phosphorus elements and affecting crop growth.
