Embodiment 1
[0044] In 2011, 28 mu of one-season paddy fields were selected in Sanxianhu Town, Nanxian County, and milk vetch was sown after the first-crop rice harvest in September 2011. The seed dosage of milk vetch was 2.5kg / mu. The variety of milk vetch was Hunan Soil and Fertilizer Research Institute "Xiangzi No. 1" independently selected and bred. The specific farming operations are as follows:
[0045] On September 20, 2011, the seeds of milk vetch were sown after the first rice harvest, and on May 15, 2012, the seeds of milk vetch were harvested mechanically. On the day of harvesting, disperse milk vetch stalks evenly in the field, plow and press dry, seal the drainage outlet to prevent the seeds in the vetch stalks and the seeds scattered in the field from flowing out of the field with the water, and irrigate and retting for 10 days to carry out one-season rice transplantation. plant. Shallow water and wet management in the early stage of one-season rice growth, the depth of the...

[0048] In 2011, about 25 mu of one-season rice fields were selected in Gaoqiao Town, Changsha County. In September 2011, the milk vetch was sown after the first rice harvest. The seed dosage of milk vetch was 2.5kg / mu. The specific farming operations are as follows:
[0049] On September 18, 2011, the seeds of milk vetch were sown after the rice harvest, and on May 13, 2012, the seeds of milk vetch were harvested mechanically. On the second day after harvesting, the milk vetch stalks were evenly dispersed in the field, and the drains were sealed to prevent the seeds in the milk vetch stalks and those scattered in the field from flowing out of the field with water, and the rice was irrigated and retting for 10 days to carry out no-tillage direct seeding of a season of rice. Shallow water and wet management in the early stage of one-season rice growth, the depth of the water layer on the field surface is kept at 1-3cm, which is enough for heavy dew and light sun after seedlings...
