Aqueous macromolecule-isocyanic ester stalk artificial board and preparation thereof

The invention relates to a water-based macromolecule-isocyanate straw hard board and a preparation method thereof. Straws of rice, wheat, corn or other crops, a water-based macromolecule-isocyanate adhesive and a straw interface performance modifying agent are used as raw materials, and the straws are treated by section cutting, kneading and modification, adhesive application and heat pressing to produce the water-based macromolecule-isocyanate straw hard board. A mixture ratio of the absolute dry straws to the water-based macromolecule-isocyanate adhesive to the straw interface performance modifying agent by weight is 100 to 10-16 to 0.05-0.15. The straw hard board uses the water-based macromolecule-isocyanate adhesive to replace a pure isocyanate adhesive, radically improves the problems of toxic organic volatiles, poor prepressing performance, adhesion on boards, etc., remarkably reduces cost and really realizes green production, and the raw materials after the treatment of kneading and modification have good prepressing and molding performances and high one-off qualified rate. The water-based macromolecule-isocyanate straw hard board has the characteristics of unique design, long active period, excellent aging, water and heat resisting performances, simple operation, easy availability of equipment, no environmental pollution, easy implementation, etc., and produces huge entironmental, social and economical benefits after the water-based macromolecule-isocyanate straw hard board is popularized.

Humic-acid silicic-acid biodegradable agricultural mulching film

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.

A high-calcium selenium-rich chromium-rich multifunctional fertilizer for rice and a preparing method thereof

The invention relates to a high-calcium selenium-rich chromium-rich multifunctional fertilizer for rice and a preparing method thereof. The fertilizer prepared by adopting maifan stone, zeolite, bone meal and the like as raw materials and by a proper weight ratio can restore and improve soil after the fertilizer is applied to the soil. The fertilizer can also be used for producing disease-preventing functional grain products. The fertilizer controls disease and pest harm, is slow-release, has durable fertilizer efficiency and promotes nutrient absorption of crops. The fertilizer is suitable for plantation of rice, wheat, millet, and other types of grains. By virtue of a compulsive cultivation technique, organic mineral elements are accumulated in fruits after the elements are absorbed by the crops, quality of obtained grain products is good, contents of calcium, selenium and chromium in the products are obviously increased, and the grain yield can be effectively increased. In grains planted by utilizing the fertilizer, the calcium content is as high as 58.6 mg, the selenium content is as high as 0.18 mg, the chromium content is as high as 0.028 mg, and the grains are substantially free of harmful elements and residual toxicity and meets requirements of green food.
