Humic-acid silicic-acid biodegradable agricultural mulching film

Abstract

The invention relates to a humic-acid silicic-acid biodegradable agricultural mulching film. A plastic non-degradable mulching film is known as 'a ten-thousand disaster'. A degradable liquid mulching film has a function of preserving soil moisture and heat but is poorer than the plastic film, and resists cold and heavy wind but cannot be trodden by people and livestock. One of the defects is that the degradable liquid mulching film cannot be moved and weeds cannot be pulled. In the 1980s, the foreign biodegradable mulching film is introduced into the Chinese market once, but the price is too high, so the foreign biodegradable mulching film is not suitable for the national condition and is out of the market. Low-cost natural organic raw materials, humic acid and silicic acid are activated by biological bacteria, rice, wheat and tobacco straws are smashed and are decomposed and fermented by decomposing bacteria to extract humic acid materials, silicic acid reacts with a degradable binder containing nutrient elements needed by plant growth and a filmogen for mixed-graft modification and compounding and drying to form the film, and the film is applied to arid and semi-arid land. The product is degraded to become fertilizers, and is a new technology product which is affordable by the planting industry, and is convenient and practical and environment-friendly.

Description

technical field [0001] The invention relates to the field of biochemical industry. This kind of mulch is a molded mulch, not a liquid spray mulch. It is based on polyethylene, polyvinyl chloride, polyvinyl alcohol, starch, degradable photodegradable mulch (shelf film) and petroleum asphalt. , modified starch, bentonite, HA-Si polymer water-absorbing resin and other liquid mulch containing humic acid substances can be decomposed and fermented by biological bacteria, and the extraction and adhesive can be cracked, and then degraded into organic matter (fertilizer). Achieving sufficient raw materials, low price, turning waste into treasure, protecting the environment, preserving moisture, heat preservation, and improving the agricultural mulching film that overcomes the shortcomings of the existing liquid mulching film. technical background [0002] The widespread use of non-degradable plastic mulch, which increases production at the expense of environmental protection and land...
