Xiangcheng City, Henan Province changes Straw from "waste" to "Treasure"

"in previous years, there was no place to put the wheat straw, but this year the government helped to sell it for a few more money. I mobilized my relatives and friends to send the wheat straw to the purchase point, and the wheat straw turned from annoying waste into a treasure of getting rich." A few days ago, Li Songfa, a villager of Caoyao Administrative Village, Lizhai Town, Xiangcheng City, said happily.

Technology makes straw a treasure. This year, Xiangcheng was faced with the hard task of "banning burning." as soon as the cadres swept away their sad faces, the farmers' ideas changed greatly. When the wheat is harvested, we only hope that the stubble will be shallower in previous years, but only the ears of wheat will be harvested this year. In the past, when farmers harvested wheat, if they could not sow seeds in the soil moisture, they had to spend more money to fight drought and plant autumn. Nowadays, what makes farmers change their ideas is science and technology, specialization, and find a new model: when sowing in summer, the straw is crushed and returned to the field, and the soil is covered to preserve soil moisture. After the wheat harvest is completed, the subsowing machine is hung on the same sowing machine, and the subsowing and sowing and fertilization are completed at one time. About 70 yuan per mu can be saved. When sowing in autumn, according to this method, it can not only increase soil fertility, maintain soil moisture, but also restrain soil diseases, which can increase the yield by 50kg / mu compared with the traditional tillage method.

EM technology creates wonders. Xiangcheng promotes EM technology to produce biological bacterial fertilizer: a pile of 300m3 straw is treated with bacterial fertilizer, and seven days later, the huge straw is piled into a small pile of brown straw maturity. The conversion of 1 ton of straw only needs 6 kg of bacterial fertilizer, and the cost is low. In addition to being used for straw ripening, biological bacterial fertilizer can also be used to prepare different strains and concentrations according to the needs of different crops.

Spraying this bacterial fertilizer can increase the yield of wheat by 5% to 10% at seedling stage, green stage and filling stage, which is higher than that of general new wheat varieties. If 2 kg of bacterial fertilizer is sprayed per mu when ploughing, nearly half of the chemical fertilizer can be reduced. At present, this technology has been extended to 200000 mu in Xiangcheng, with a cumulative increase of 7.2 million kg of grain.

The straw is processed into "golden beans". Wang Tongsheng, a farmer in Wangmingkou Town, Xiangcheng City, has a straw granulation processing plant. Piles of straw are swallowed into the machine. After processing and drying, round particles come out. This kind of "golden bean" can be used as feed and as fuel for vaporization furnace. Straw processing plants like this can digest straw from two or three villages and towns every year. In addition, the development of aquaculture by ammoniation of straw silage and the development of new energy by fermentation biogas have also been popularized and applied in the city.

Li Qian, director of the Xiangcheng Institute of Agricultural Sciences, said: "We actively promote the comprehensive utilization of straw, starting from the link of receiving and sowing, using EM technology to transform, and relying on small enterprises for processing, which can not only relieve farmers' worries about dealing with straw with more money, but also solve the difficulties of soil fertility loss and grain production increase. Today, straw has become a 'hot cake' in the hands of farmers, which makes cadres feel at ease and the masses at ease. "
