The prohibition of incineration of straws and the implementation of straw mechanized returning to fields are undoubtedly beneficial to reducing pollution, protecting the environment, developing agricultural production, and generating recycling benefits, but it is necessary to actively explore the institutionalization and long-term effects of the practices during the World Expo, and regard the comprehensive utilization of straw as a change. As one of the important aspects of the agricultural economic development, Shanghai still faces many problems that need to be solved.

The annual total straw production in Shanghai is about 1.6 million tons, and the total volume has remained stable. It is understood that the major bottlenecks encountered by Shanghai at present in promoting comprehensive utilization of straw are: high cost of mechanized land return, low enthusiasm for farmers to return fields, difficulty in work promotion, basic gaps in the collection and transportation system, low overall utilization rate, and comprehensive utilization enthusiasm of enterprises not tall. The Agricultural Machinery Department also confirmed that it is difficult for the summer crop straw to return to the field with large total amount of straw, tight time for seeding, difficulty in operation, and high technical requirements.

To this end, Sun Lei, the director of the Shanghai Municipal Agriculture Office and the Municipal Agriculture Commissioner, put forward the requirement of “treating hardships and overcome difficulties”. He said that “Shanghai must seize new opportunities, persist in advancing trends, be bold in attacking difficulties, and actively explore new ways of comprehensive utilization of straw. To achieve the objective of "comprehensive utilization of crop stalks, supplemented by the return of machinery to the field, and resolutely incapable of burning."

Shanghai will break down the key tasks of promoting comprehensive utilization of straw into five categories:

Efforts will be made to promote the return of mechanization to farming, to adhere to the agronomy and agronomy of agricultural machinery, and to support agricultural households and agricultural machinery service organizations to promote the mechanization of straw return. On the basis of continuing to provide subsidies for the purchase of machinery returned to the field, a subsidy will be given to the cost of mechanized operation for returning to the field;

Establish and improve the straw collection, storage and transportation system. The district/county, township and township governments determine a reasonable straw collection and treatment scheme according to local conditions, and support enterprises, farmers' specialized cooperative organizations and farmers' brokers to carry out straw collection, storage and transportation;

Increase the comprehensive utilization of straw in the processing of commodity organic fertilizers, encourage the purchase of straw processing equipment and other measures in commodity organic fertilizer processing, increase the proportion of straw utilization, and solve the problem of comprehensive utilization of straw in a certain area;

Expand the utilization scale of straw in edible fungus culture materials and feed, establish centralized treatment center for edible mushroom culture materials, exert scale benefits, carry out technical research on utilization of straw in feed, and expand the utilization scale of straw in feed;

We will promote the comprehensive utilization of straw in new building materials, renewable resources, renewable energy, and other areas, adhere to local conditions, rely on technological progress, and actively promote the comprehensive utilization of straw in these emerging fields.

In addition to returning straw to the field, the amount of straw currently used in Shanghai is still very small. Last year, it accounted for only 3% of the total amount of straw. Low economic efficiency is the main reason why straw is difficult to be fully utilized. The cost of straw collection, storage, transportation, and processing is relatively high. At present, artificial collection and treatment of straw cost 400 yuan per mu, and the cost of cutting and returning to land is less than 30 yuan.

However, if the economic benefits of comprehensive utilization of straw are greatly increased, it is believed that the comprehensive utilization will increase greatly. The reporter was informed in the interview that the comprehensive utilization of straw is entirely feasible, and Shanghai’s existing scientific research results have explored multiple approaches for the comprehensive utilization of straw, as long as further strengthening technology research and development and technological innovation, taking into account its economic rationality and scale With the market, you can have both the agricultural production and the natural environment, so that the sky is always blue air fresh.

During the interview, the reporter found that the most exciting thing is that the successful cases of comprehensive utilization of straw have a characteristic. When the golden straw turns waste into treasure, its whole life cycle is green, and it is energy-saving and emission-reducing at the time of production. When it comes to low-carbon and environmental protection, many of them are recyclable and recyclable even when they are discarded. I believe this industry, which makes life better, is full of promise.
