The realization of the "five material" comprehensive utilization of straw in Xingan Meng of Inner Mongolia, to fully tap the value of straw, straw feed, fertilizer, base material, raw material and fuel of the "five material" by way of connecting a low carbon environmental protection, farmers income and improve the benefit of enterprises "green industry chain".
Corn, rice straw, and alfalfa were rolled into pellets. According to a certain proportion, adding food, salt and other raw materials, you can become a nutritious meal of livestock to farmers to bring more than 120 yuan per mu of income.
Corn cob and corn stalk can be made into base material for edible fungi by crushing, fermenting and other rough processing. Edible fungus sticks include corn cob 50%, sawdust 25%, straw 20%, each can produce 1.5 Jin letinous edodes, each letinous edodes greenhouse annual output of 12 thousand pounds, to achieve sales revenue of 40 thousand yuan. Corn stalks, rich in nutrients, can also be used to make fertilizer. Tuquan County by means of straw fertilizer, the annual consumption of 300 thousand tons of straw, 100 thousand tons of organic fertilizer production.
Xintai group to corn, sorghum, sunflower and other crops straw as raw material, the production of straw fiber super polyester tile, the annual consumption of 20 thousand tons of straw, straw and straw tile production of 15 million square meters of building materials products. Today, Xingan Meng straw "five material" comprehensive utilization amounted to 3 million 600 thousand tons, farmers and herdsmen feeding and living straw 1 million 800 thousand tons, the total amount of corn straw about 5 million 400 thousand tons, fine utilization rate of 60%.
Straw is considered "the other half of agriculture," said Yin Chengjie, President of the China agricultural economic society. "Full use of straw can produce both economic and environmental benefits.".
On the one hand, straw comprehensive utilization can adjust the energy structure and protect the environment. The straw into biomass fuel can improve the existing energy structure, Xingan Meng science and Technology Secretary Wang Yongsheng said, the burning effect of 2 tons of straw particle equivalent to 1 tons of coal in Xingan Meng, with an annual output of 11 million tons of straw particles can reach 5 million tons of coal. The general manager of Gabriel biomass energy development Co., Zhang Yuxin said, compared with coal, straw biomass fuels, clean and environmental protection, to achieve zero emissions of carbon dioxide, sulfur content less than 0.06%, low nitrogen content, can effectively improve air quality, efficient and cheap, the same heating condition is lower than the cost of natural gas and electricity.
On the other hand, straw comprehensive utilization can increase land yield and resource utilization, and increase economic benefits. Wang Yongsheng believes that the comprehensive utilization of straw can become an important source of agricultural output value. Farmers sell straw, an acre of land can be increased from 120 to 200 yuan, the straw fertilizer into the field, per acre can also increase from 600 to 700 yuan. His calculations to reporters: 1 tons of straw can be made of 0.9 tons of feed, 1 sheep a year to feed about 1 tons, about 3 tons of feed to 1 cattle a year, Xingan Meng currently has 10 million sheep, 600 thousand cattle, the annual utilization of corn straw feed can produce about 10 million tons, which can feed all the the existing 5 times the number of sheep or cattle, can make the most of the grassland rehabilitation alliance.
