China Economic Net, December 15 (Reporter Liang Mu) According to the Ministry of Agriculture and Rural Affairs, this year's launch of grain and oil and other major crops large-scale yield improvement action has obvious results, in the case of local disasters are more serious, large-scale yield improvement effectively hedged the impact of the disaster, to achieve the abundance to make up for the arrears, to make up for the summer with autumn.
According to the National Bureau of Statistics, the annual grain output hit a record high of 13,908200 million catties, the average grain yield per mu is 3897 kg, raise 29 kg, the contribution of the yield increase to the increase in yield reached 587%。It is estimated that the growth rate of grain yield in the counties that carry out large-scale yield improvement actions is 8 percent higher than that in non-project counties8 percentage points, 300 soybean and corn integrated counties to promote the increase in yield, the contribution rate to the increase in grain production reached more than 73%. The role of large-scale yield in the increase of the high level of grain output in the country is prominent.
In the first half of the year, the Ministry of Agriculture and Rural Affairs deployed a large-scale yield improvement action meeting, pointing out that China's agricultural production is still the traditional promotion model of "single-technology-based and small-area demonstration", the field production technology in place is not high, and the yield of major grain and oil crops still has a lot of room for improvement. Since the beginning of this year, the Ministry of Agriculture and Rural Affairs has taken the improvement of large-scale yield as the number one project of grain production, and has integrated more than 20 billion yuan in conjunction with the National Development and Reform Commission and the Ministry of Finance, and promoted the whole system of 100 soybean and 200 corn key counties.
It is understood that the effectiveness of the action is mainly reflected in two aspects:
First, the planting density has generally increased. The increase in density is an important factor and significant feature of soybean and corn yield increase this year. Focusing on the key of increasing planting density, various provinces have focused on promoting high-yield technologies such as dense planting of soybean high platforms and large ridges, and precise regulation and control of corn densification, and the planting density of the whole demonstration county has increased significantly.
Second, the yield of large areas has increased significantly. The high-yield typical of various regions presents new characteristics such as large contiguous area, large number of cases, and high seasonal yield.
