Embodiment Construction

[0015] Below in conjunction with specific embodiment the present invention is described in further detail:

[0016] A humic acid-degradable liquid fertilizer mulching film, the composition and weight ratio of which are as follows: 55%-65% of humic acid, 4%-6% of accelerator, 13%-17% of stabilizer, and 13%-17% of film-forming agent , water 4%-6%. The humic acid is weathered coal or lignite. Described accelerator is sodium hydroxide. The stabilizer is urea. The film-forming agent is starch, and the starch is corn starch, potato starch, phosphate starch, oxidized starch, etherified modified starch, carboxyl modified starch, graft modified starch or biological enzyme modified starch.

[0017] The humic acid degradable liquid fertilizer mulching film also includes 0.1%-6.9% of micro-fertilizer and 0.1%-9.9% of chemical fertilizer.

[0018] The production method of the humic acid degraded liquid fertilizer mulch film is as follows: 55%-65% of humic acid, 4%-6% of accelerator, 13...

Abstract

A humic acid degradable liquid manure plastic film is characterized in that the components and content proportions by weight are as follows: 55% to 65% of humic acid, 4% to 6% of accelerant, 13% to 17% of stabilizing agent, 13% to 17% of film former, and 4% to 6% of water. The humic acid degradable liquid manure plastic film can reduce more than 30% of groundwater evaporation, the soil moisture content is increased by more than 20%, and the water preserving effect is good; the ground temperature of the soil 30 to 50 mm under ground is increased by 1 to 4 DEG C, the crop growth and development period is 3 to 10 days ahead, and the heat insulation effect is good; the fertility is added, and the content of humic acid in liquid plastic film is greater than 90%; the permeability is added, the soil volume weight is decreased by 6 to 10, the soil granulation amount is greater than 0.25, which is increased by more than 10.

Description

technical field [0001] The invention relates to a covering, in particular to a humic acid-degradable liquid fertilizer mulch and a production method thereof. Background technique [0002] The existing plastic mulch is difficult to decompose in the natural environment, and it is scattered in the soil and the natural environment, destroying the soil structure and causing white pollution to the soil and the environment. [0003] Announcement number: CN1277228, Announcement date: 2000.12.20 Chinese patent document announced a "multifunctional degradable black agricultural mulch film", its component system includes asphalt, starch, film forming agent, surfactant, stabilizer, water , Chemical fertilizers and micro-fertilizers, pesticides, herbicides, etc. required for plant growth. The film not only has general biological and photodegradation functions, but also can adjust the content of starch and the types and contents of pesticides, herbicides, and micro-fertilizers to obtain ...
