New wheat species
Zhang Changgui, a farmer, does not worry about handling straw. On August 25th, the reporter saw the contracting farmland of Zhang Laohan in Lulin Village, Shanshui Town, Guanghan City, and saw that the straw left over from the harvest the previous day was randomly placed in the fields. “Why not put the straw in order to put it neatly?†Zhang Laohan replied: “No, when two more months of wheat are ordered, these straws will be completely covered in the field and used for waste. Now we first soften the grass with sunlight and rain. In the past, the time-consuming and time-consuming production was low. In fact, straw's “turning waste into treasure†is just one of the benefits of using this technology. The abbreviation that the Provincial Department of Agriculture is currently promoting is the new technology for the cultivation of wheat by rice buckwheat is a combination of three measures: no-tillage, exposing and straw-covering. According to the introduction of Tang Yonglu, an expert in crop cultivation of the Provincial Academy of Agricultural Sciences, wheat is cultivated in the traditional way of plowing and fine seeding. Affected by Sichuan's climatic conditions, the total output is 300 kilograms per acre. In previous years, no-tillage axilla technology was used. Labor is also time-consuming: 33,000 litters per mu, to be nested, on-demand, cover species, and back and forth three times. A skilled worker can only broadcast a maximum of 4 points a day. Today, save money and save money In 1995, our province began to demonstrate the promotion of wheat cultivation technology. Zhang Changgui said that last year he used this method to grow wheat and spread fertilization materials one day after leaving the field, and then used a 100 yuan simple planter to plant a row with a spacing of 20 centimeters and a 10 centimeter spacing, which was broadcasted in just 1.5 hours. Mu, and the use of species than the traditional way to save about 5 kg. Then cover the field with straw and finish. One mu of land covered by agrarian grass just covers an acre. To solve the problem of straw outlets and increase income, the technology that won the second prize of the 2001 Sichuan Provincial Science and Technology Progress Award has now become the lowest cost investment in the history of wheat production in the province, and the best growing income benefit is: Compared with the cultivation under the same conditions of rotary tillage The average cost savings is 26%, labor savings are 23%, production is increased by 11%, and revenue is increased by 48%; compared with no-tillage cultivation, savings are 20%, labor savings are 86%, production increases by 7.5%, and income increases by 27%. What is more important is to solve the straw out problem. This technology was used in 800 acres of land in Jinhua Village of Lianshan Township in Guanghan last year, with an average yield of 330 kilograms per mu and a cost of less than 200 yuan per mu. The technology currently has a total of 15.68 million mu in the province, with a net new social benefit of 1.4 billion yuan. Last year, the province promoted this technology in the 528 million mu of cropland in the western Sichuan Plain and the basin perimeter, accounting for 60.4% of the 875 million mu of rice buckwheat planting area of ​​the province.
