Sesbania is an ideal green manure crop, and intercropping with food crops also has the effect of transforming saline land and increasing soil fertility. This year we have engaged in the intercropping experiment of Sesbania and rice, focusing on the interaction between growth and development and final production. First, the test process The test area of 0.5 acres, mu of miscellaneous fertilizer 4M ~ 3, adjacent to the paddy for control. The rice variety is Hongqi No.4, transplanting rice on May 18, the density is 6 × 6 (inch), 6 plants per hole and 100,000 basic seedlings. Sik Jing sown on April 20 and moved on June 21
