Plate-type fertilizer package slow-releasing structure

Abstract

The invention provides a plate-type fertilizer package slow-releasing structure. The plate-type fertilizer package slow-releasing structure comprises a plate body, wherein a plurality of dividing lines are arranged on the plate body in a crisscross manner, and divide the plate body into a plurality of rectangular zones with equivalent area; grooves and the plate body are integrally formed during the manufacture, and the grooves are formed in the rectangular zones; the plate body is prepared from resin; fertilizer bags are arranged in the grooves in an embedded manner; fertilizers are packed in the fertilizer bags; the casings of the fertilizer bags are made of sulfur coated urea; a plurality of through holes are formed in the casings of the fertilizer bags; the grooves and the fertilizer bags are covered with plastic films; 2-3 supports are arranged on the periphery of each groove, and the height of the supports is greater than the depth of each groove. The plate-type fertilizer package slow-releasing structure is simple, convenient to use, long in slow-releasing time and good in fertilizer efficiency, and a coating for the structure is not easy to break during transport.

Description

[0001] technical field : [0002] The invention relates to the technical field of organic fertilizers, in particular to a plate-type fertilizer packaging slow-release structure. [0003] Background technique : [0004] Slow-release fertilizers are also known as slow-release fertilizers or controlled-release fertilizers. The nutrient-containing compounds in the fertilizer are released slowly in the soil or the nutrient release rate can be controlled to a certain extent for the continuous absorption and utilization of crops. Slow-acting fertilizers are divided into three categories: (1) insoluble compounds in water, such as magnesium ammonium phosphate, etc.; (2) coated or coated fertilizers, such as sulfur-coated urea, etc.; (3) carrier slow-release fertilizers, namely fertilizers Fertilizers in which nutrients are physically or chemically bound to natural or synthetic substances. [0005] At present, the main slow-release fertilizers are coated fertilizers. The main va...

AI Technical Summary

Problems solved by technology

[0009] The key to resin-coated urea is the uniformity and controllability of the coating and the stability of the coating. Some coated urea coatings are very brittle and even in It is easy to fall off during transportation and affect the effect of the coating. The uneven thickness of the coating and the different release rate are also factors that affect the application effect of coated urea.

At present, there is still a problem with coated urea. Some coating processes are more complicated, and the price of coating materials is relatively high. After coating, the cost increases too high.

Affect the application range of fertilizers. Some coating materials are not easy to degrade in the soil. Long-term continuous use will also cause pollution to the soil environment and damage the physical properties of the soil.
