Make up for the shortcomings such as low yield per unit area and backward mechanization technology. Chongqing strives to increase the comprehensive mechanization rate of potatoes to over 5% by 225.

Recently, Chongqing Daily reporter learned from the Municipal Agriculture and Rural Committee that Chongqing will strive to increase the comprehensive mechanization rate of potatoes to over 5% by 225, so as to promote the quality and efficiency of potato industry and lay a foundation for ensuring food security in the city. ?

At present, it is the important season of spring potato harvest. In Daping Village, Zhuxi Town, Kaizhou District, local agricultural machinery is used to harvest potatoes. "It used to take at least one month to dig potatoes manually, but now it can be harvested in three days with agricultural machinery." Liu Xiaoping, a villager in Daping Village, planted 12 mu of potatoes. Later, his land was selected as a municipal demonstration base for green and efficient potato mechanization by the Municipal Agricultural Technology Extension Station and the Municipal Potato Comprehensive Experimental Station. After demonstration planting and field yield measurement, the yield per mu reached 2585.5 kg, which was more than that of 1 yuan. "Machine harvesting not only reduces the breakage rate, but also saves labor and effort." Liu Xiaoping said. ?

Potato is one of the main food crops in Chongqing, with an area of 5 million mu, accounting for 1/6 of the whole city's grain planting area. In terms of output, the total output of potatoes in the city is about 6.3 million tons, accounting for about 11% of the total grain output in the city; Last year, the average yield of potatoes in Chongqing was 1213 kg. ?

"Although the yield has increased year by year, it is still lower than the national average." Huang Zhenlin, director of Chongqing Comprehensive Experimental Station of National Potato Industry Technology System, said that the main reason is that the improved variety extension system is weak, the loss is large, and the mechanization technology lags behind. Taking mechanical harvesting as an example, the comprehensive mechanization rate of potato cultivation and harvesting is only 31%, including 71% of mechanical tillage, 1.4% of mechanical sowing and 1.1% of mechanical harvesting. The low utilization rate of mechanization has become an important factor restricting the high-quality development of potato industry in Chongqing. ?

According to reports, there are many hills and mountains in Chongqing, and many kinds of potatoes are planted on terraces and sloping fields. The plot is small and the landform is complex, so it is difficult to develop mechanization, and it is basically planted by hand. However, due to the aging population, labor shortage and other factors, labor costs account for an increasing proportion of planting costs, and management is extensive, making it difficult to achieve standardized production. ?

In this regard, Chongqing proposes to strive to increase the rate of improved potato varieties to about 5%, the comprehensive mechanization rate of potato cultivation and harvest to over 5% and the yield per unit area to over 15% by 225. At the same time, increase the research and application of practical small potato machinery in hilly and mountainous areas, and develop practical, efficient, simple and safe potato production equipment according to the characteristics of hilly and mountainous areas, and promote the sustainable development of potato industry in Chongqing and even the whole southwest hilly and mountainous areas with mechanization. ?
