Corn production and Wulanchabu seem to be a pair of unrelated concepts. However, in recent years, corn production in Wulanchabu, a land regarded as "0", has gradually been put on the main seat of agriculture and has become an important measure for agricultural development in the whole Union. It can be said that the popularization of corn production has opened the prelude of agricultural reform in Wulanchabu League. Wulanchabu plastic film corn technology has gone through more than ten years from demonstration to popularization, from dry land to dry land, from Qianshan area to Houshan area. It is the market economy that injected the catalyst for the popularization of this new technology. At present, corn production has become an extremely important part of developing grain production, adjusting planting structure, increasing economic income and realizing enriching the people and strengthening the government.

The accumulated temperature in Wulanchabu League is low, the average annual precipitation is 400 mm, and the frost-free period is about 120 days. Before the application of plastic film, the planting area of corn in the whole league was only 2. 530,000 mu, yield per mu 175 kg. 1986 after the success of the corn plastic film mulching experiment, with the efforts of agricultural science and technology personnel, the corn plastic film mulching area expanded rapidly. At the same time, the technical personnel of the whole league pay attention to the deep digging of plastic film corn, forming a new three-dimensional agricultural pattern of intercropping and interplanting. In recent years, on the basis of summing up experience, the League has further improved technical measures and strengthened project management, and achieved remarkable results in corn planting. Planting film-covered corn in a large area has accelerated the popularization of advanced and practical technologies, improved farmers' scientific farming level, made full use of the natural characteristics of Wulanchabu League, such as abundant sunshine and large temperature difference between day and night, greatly increased corn yield, created a new yield level, and achieved obvious economic benefits.

The new corn technology has not only brought everything to Wulanchabu League today, but also its long-term significance lies in tomorrow. Film-covered corn has changed farmers' traditional ideas, which is precisely the key to getting rich in the market economy, and this invisible force has gradually spread to other fields of agriculture. "Farming around the market and adjusting the structure to make money", a resounding slogan with the characteristics of the times, is widely circulated in Wulanchabu League, which points out the development direction of agriculture and represents the future and future of agriculture in Wulanchabu League.
