"Straw bioreactor technology" introduced in our province Qinhuangdao, Wuji, Leting, Yongqing demonstration and promotion of 2800 mu, have shown good results. The main method of this technology is to use microbial bacteria to decompose corn (or other crops) straw There are two types of decomposition, built-in type and external type.The built-in type is embedded in the ground under the trenches, and the external type is to stack and react the straw, collect the carbon dioxide gas produced by the reaction, supply the crop growth needs, and promote crop yield increase.
According to a survey of 8 farmers and 11 vegetable greenhouses in Yongqing County using "straw bioreactor" technology, the greenhouse, base fertilizer, chemical fertilizer, and pesticide reduction in application of two-thirds of cucumbers and tomatoes will not only increase production, but also increase production. Improve quality. Zhang Peihai, a vegetable farmer using this technology, said that in previous years, more than 20 chicken stalks were applied in one shed, 1,000 yuan was spent on chemical fertilizers, and pesticides were sprayed in three to two days. The whole shed was picked 300 jins of cucumber every two days; this technology was applied this year. Picking more than 500 kilos of cucumbers every other day, the vegetable cultivator Liu Jingan of Wawu Xinzhuang Village said that this technology has solved the big problem of our vegetable farmers. First, corn stalks become waste and treasure; second, winter temperatures can increase the cadastral ground temperature above 4 degrees; Solve the technical problems of vegetables without pollution. According to the test and demonstration summary of the Vegetable Management Center of the Qinhuangdao Bureau of Agriculture, the application of underground burial straw to a built-in technology (requirements for internal and external applications) can increase the temperature in the winter shed by 2-4 degrees, and increase the temperature by 2-3%. Degree; plant growth is robust, the incidence of diseases and insect pests is reduced, the fruit setting rate is significantly increased. Especially in the cold winter, the effect is more obvious. The output is nearly doubled. The average growth of the entire growth period is more than 30%. The quality of the product is significantly improved and the soil structure is significantly improved.
"Straw bio-reactor" technology is a major innovation in greenhouse vegetable cultivation, and has a good promotion and application value. The application of this technology can make crop straws be converted, can greatly reduce the amount of pesticides and fertilizers, and can significantly improve the quality and output of vegetable products. It is an effective technical support for the realization of pollution-free vegetable production. It can save energy, reduce costs, and promote the sustainable development of agriculture.
