Several methods for rational use of straw

[ China Agricultural Machinery Industry News ] In autumn, although there is no colorful spring, there is no summer foliage, no winter snow, but autumn is a harvest season. In October, the farmer’s hard-working crops are ripe. A stubborn, full-bodied wheat humbled his head in humility. Many people are immersed in the joy of the autumn harvest, but the ensuing is the smell of burning, pungent ... We all know that straw burning is the "culprit" of smog weather, and A large amount of toxic and harmful substances are produced during the burning process, posing a threat to the health of people and other organisms.

With the rapid development of China's economy, more and more attention is paid to environmental protection, and the autumn harvest season is a new stage of environmental protection. Air pollution is a major item in environmental protection, and air pollution caused by straw burning in rural areas is becoming more and more serious. Therefore, other more environmentally friendly methods must be adopted to promote the comprehensive utilization of straw, so as to achieve sustainable rural economy. Cycle development. With the introduction of new energy and the environmental awareness advocated by the society, people's deepening, how to use straw more environmentally friendly? This issue has become the focus of the whole society.

In fact, straw burning is improving resource utilization.

(1) Straw returning

Things should be taken from the fields and used in the sky, so the crop straw is no exception. The nutrients needed for crops include nitrogen, phosphorus, potassium, sulfur, calcium and other nutrients. Do you know? Straw is rich in these nutrients! In this way, the return of straw to the field has undoubtedly achieved the goal of full utilization and harmlessness. Straw returning is to let the crop straw pass through the smash and then bury it in the ground, and then let the microbes in the soil corrupt and decompose the straw. On the other hand, the smashed straw enters the soil, which can cover the ground and greatly reduce the evaporation of water in the soil, thus effectively increasing the organic matter in the soil and increasing the water retention, heat preservation and air permeability of the soil. To improve soil fertility. This method has also been effectively utilized in many places, but many farmers feel that this is very troublesome and the use of machines is required to crush the straw, which in turn will increase the cost. To this end, the government departments have given corresponding subsidies in order to allow farmers to actively participate in the action of returning straw to the field. This should be an effective and convenient method.

(2) used to extract industrial raw materials

We all know that the raw material for papermaking is wood, and corn stover, wheat straw, rice straw can also be used for papermaking, and it is also possible to improve fiber-reinforced wood. This will undoubtedly make up for the shortcomings of insufficient timber resources, and it can also reduce the amount of wood felled, thus increasing the coverage of China's forests. This is undoubtedly a sustainable process of ecological cycle development. To this end, this method can be widely used not only to effectively improve the shortage of wood resources in China, but also to protect various environmental pollution caused by straw burning.

(3) Cultivating edible fungi

It is well known that crop straw contains very rich organic matter, which can achieve biotransformation, and according to the data, its conversion rate can reach 300%. Therefore, straw is a good material for cultivating edible fungi, and the amount of straw is much cheaper in the rural harvest season. In this way, the cost of use is greatly reduced, thereby increasing the profit and invisibly solving the problem of insufficient raw materials. Achieved a sustainable cycle of agro-ecology.

(4) Strengthen farmers' awareness of environmental protection

The countryside is a place with weak economy, and the education of farmers is also lacking. Many farmers are also very weak in environmental protection, so there will be a lot of incineration of straw on the spot. Government departments need to increase education and training for farmers. TV broadcasts, on-site explanations and other relevant channels can be used to explain and play a role in publicity and education, thereby raising farmers' awareness of environmental protection. Let farmers have a correct understanding of the ecological and economic benefits of comprehensive utilization of straw and the various hazards brought by burning straw, so that farmers can effectively and comprehensively utilize straw.

The problem of straw burning has seriously affected the development of the environment and society and controlled the burning of straw. Each of us should have the awareness of protecting the environment, and we must deal with this environmental pollution problem reasonably and legally. 2017 crop straw, do you know how to use it?
