Amplification effect of Green Recycling Agriculture

"this technology of growing both grain and beans has existed before, but it is really difficult for farmers to use this technology. The reason is that there is very little land for each household, which can not form economies of scale. " Xue Yaohui, chairman of Wanxin Farmers' Professional Cooperative in Gongzhuling City, Jilin Province, said that if we want to turn the integrated technology of agricultural production into the great achievements of universal farmers, we must innovate ideas and technologies. As long as we innovate ideas, we can boldly apply these integrated technologies, make these technologies go into the fields and become a scientific and technological force for farmers to get rich. Innovative technology is to further improve, improve and innovate these technologies in agricultural production practice, so that these technologies can really play a role in promoting the development of modern agriculture.

Grow grain and beans at the same time to increase the income of the two projects at the same time. One is to increase grain production and income, that is, to increase the production and income of corn and soybeans, and the other is to increase the "green income" of land fertility. In 2015, Wanxin Cooperative set aside 30 hectares of arable land for grain and bean planting experiment, which requires planting four rows of soybeans and four rows of corn in the same plot, so that they can grow both crops over and over again. As the combination of grain and bean is a combination of height and height, the grain in the field is well ventilated, sunny, big panicle, resistant to lodging and high maturity of grain and bean. This method can closely plant soybeans and corn per hectare. Take corn, for example, the Wanxin Cooperative can plant more than 73000 plants per hectare of cultivated land. The average yield of corn and soybeans per hectare is more than 27000 jin and 5200 jin respectively. In the words of Xue Yaohui, "in this way, I have harvested not only one hectare of corn but also one hectare of soybeans from one hectare of arable land. I planted one hectare of land and produced two hectares of grain. In addition to our normal income, our 30-hectare experimental plot has earned an extra 350000 yuan. "

Due to the increase of chemical fertilizer input in land cultivation in recent years, some cultivated land appeared serious consolidation, and the fertility of cultivated land decreased obviously. The advantage of planting grain and beans at the same time is that each variety does not leave stubble in the second year, that is, the following year, corn is planted on the ridge of soybean, and soybeans are planted on the ridge of corn. The rhizobium of soybean is beneficial to the growth of corn, and the root of corn is beneficial to the growth of soybean. after they rot in the field, they become green resources to improve soil fertility. Due to the alternating rotation of grain and beans, the occurrence of diseases and insect pests has been greatly reduced. At the same time, when harvesting corn and soybeans, the straw will be left high stubble or crushed directly back to the field, these practices have played an important role in alleviating soil consolidation and increasing green fertility.

Cooperatives also increase the value of grain straw and by-products by raising breed cows, thus realizing the green cycle of the whole grain production chain. At the end of 2012, the cooperative spent 2 million yuan on 200 breed cows to raise value through the belly of by-products such as grain straw. The result of the experiment is that a cow can consume one hectare of corn straw a year, and a cow can produce 15-30 jin of cow manure organic fertilizer every day, and can produce more than 4 tons of organic fertilizer a year, which is enough for one hectare of land. 200cows can produce at least 170calves per year, and the calves will be fenced in four months. The price of each calf is about 7000 yuan, and the output value is nearly 1.2 million yuan.

As the organic manure of cow manure is returned to the field year after year, the cultivated land of the cooperative has more and more organic matter, less and less chemical fertilizer is used, and the grain produced is full, tastes good, and is green without pollution. more and more people gather here to buy the food they produce. Now the grain they produce from land, sowing, harvesting, processing, breeding to returning organic fertilizer to the field, the whole industrial chain has achieved a green cycle.

The highlight of cooperative income generation also lies in saving money for farmers and turning waste into treasure. If members themselves need 7500 yuan per hectare from farming to harvest and hand it over to the cooperative for farming, it costs only 5000 yuan per hectare, and they can sit at home and wait for a bumper harvest in autumn. After the grain harvest, the co-operatives store grain for the farmers free of charge, and the farmers have to sell the grain, and the cooperatives buy it at a penny higher than the market price. On the other hand, all the straw in the cultivated land is packaged and transported by the cooperative and sold to the power plant, producing more than 6 tons of dry straw per hectare, the recovery price of the power plant is 240 yuan per ton, the gross profit of straw per hectare is more than 1400 yuan, excluding various expenses, the cooperative makes a profit of 700 yuan per hectare, and the income of straw feeding cattle is more than 900 yuan per hectare, and the annual income of cooperative straw reaches more than 500,000 yuan. Mr sit said: "one of our objectives is to effectively prevent farmers from burning straw in the fields after the autumn harvest and before farming, causing environmental pollution. We have turned the abandoned straw of farmers into a growth point for the profits of cooperatives, which not only helps farmers clear the land, but also does not delay the spring ploughing of the following year. The second is to give benefits to farmers, from ploughing, planting to harvest, we only collect the cost, so that members can get the greatest benefits. for our members, the income of each hectare of cultivated land is increased by more than 2600 yuan.
