Changing the phenomenon of "six more and six less" is the key to improve the per unit yield of double cropping rice in Jiangxi.
Rice is the most important food crop in Jiangxi. Improving the per unit area yield of double-cropping rice is an important way to ensure Jiangxi's status as the main grain producing area and to ensure Jiangxi to make greater contribution to national food security. In recent years, although the per unit yield of double-cropping rice in Jiangxi has increased steadily, the phenomenon of low yield has not changed much. Compared with neighboring Hunan, each 667m2 is lower in 50~60kg. The analysis shows that the phenomenon of "six more and six less" is the main reason for the low per unit yield of rice in Jiangxi. The main results are as follows: 1. the amount of sowing is more and the amount of seed is less. Cultivate

High-yielding cultivation techniques of double cropping no-tillage and direct seeding of oil and rice
Zhejiang Province has a more developed economy and high labor value. at the same time, with the rise of diesel prices, the ploughing fee of cultivated land machinery increases, and the cost of grain and oil production increases year by year. For this reason, the experiment, demonstration and popularization of no-tillage and direct seeding high-yield cultivation techniques of oil and rice double cropping in Zhejiang Province have reduced the cost of grain and oil production and improved the planting benefit. According to the investigation, no-tillage direct seeding rape per mu is 62.5 yuan more cost-effective than transplanting rape, and no-tillage direct seeding late rice per mu is 70.24 yuan more cost-effective than ploughing and transplanting late rice.
