No-till Potato Planting a "New Mode in the World"
Li Ruping, head of the Guangxi Agricultural Technology Promotion Station, said that the no-till potato cultivation model can be simply described as “putting a pendulum, covering a lid, picking up a lid,†and planting the seed potatoes on the ground when sowing and then using 8-10 cm. Cover with thick straw and open the straw when harvesting. This innovative planting model has many advantages.
The first is the provincial labor force and the season. No-tillage cultivation of potatoes changed the traditional sense of “intensive farming†mode of ploughing and soil preparation, digging and planting, and cultivating and weeding, and deep-digging and digging of potatoes. This resulted in a cost reduction of 150 yuan compared with 6 to 8 man-hours in conventional farming. At the same time, a piece of rice can be harvested in the late rice field and the potato can be planted one at a time without affecting the rice production season the following year.
The second is strong resistance and high yield. According to a survey conducted by Guangxi University, the surface temperature of no-tillage cultivated potato is 3°C-5°C higher than that of conventional cultivation. In the long-term freezing and rainy weather in the southern region, it shows strong resistance to stress, and the ventilation and ventilation are good. The formation and enlargement of tubers are generally 20% to 40% higher than conventional cultivation.
Third, excellent quality and good selling prices. No-tillage cultivation of potatoes without the use of agricultural machinery harvest, not hurt potatoes, and the size of uniform, round, per kilogram of prices than conventional planting increased by 0.2 yuan per mu can be increased by more than 200 yuan.
The fourth is to increase land resources and promote environmental protection. The straw used for no-tillage cultivation of potatoes and the return of stems and leaves after harvesting can increase soil organic matter, fertility and fertility, promote the benign circulation of the ecological environment of rice fields, and avoid the pollution of fire-stalked potato leaves in the past.
The innovative cultivation mode of no-tillage cultivation of potatoes has also been welcomed by the majority of farmers. The crowd said happily: “Look at the straw and look at it. The ground is full of golden eggs.†“In the past, straw was burned. Now the grass is a treasure. It is used to grow potatoes and allows you to earn enough.†“No-till potato, big Circle, sell well, make a lot of money." "A pendulum, put a new technology; æ¡ æ¡ æ¡, æ¡ å¥½ 好 好 。 。."
According to Zhang Mingpei, Director of the Agriculture Department of the Autonomous Region, in 2003, Guangxi began to promote the cultivation of potatoes without cultivation. The five-year demonstration application area reached 3.02 million mu, with a total output of 6.2653 billion kilograms. The new output value was 1.43354777 million yuan, and the average new net income per acre was 557.59. Yuan, the application of technology is far ahead in the country.
The “new model of the world†planted by the no-tillage potato in Guangxi has caused strong repercussions at home and abroad. Many domestic and foreign potato experts and more than 10 provinces and autonomous regions such as Ningxia, Shaanxi, Jiangxi, Fujian, Guangdong, Yunnan, Guizhou, Shandong, Jilin, and Inner Mongolia have come to visit each other; the national potato no-tillage cultivation technology on-site observation and industrial development The seminar was moved to Nanning last year; the leadership of the Ministry of Agriculture instructed us to speed up the promotion of this new planting model in southern China.
