The latter quarter of rice seedlings planted Sesbania, organic rice is to solve the latter part of rice an effective way. In 1977, the test area of 25,000 mu in the suburbs was good and the result was very good. I conducted a post-season rice seedling field trials of Jing Jing, and in Shanghai Zhuanqiao, Qiyi, Qingpu County, Fengxi, Songjiang County, Si Lian, Chengxi and other communes to establish contact point. Now the test results are summarized as follows: First, the latter quarter of rice seedlings planted Jing Jing (A) Test Method: The practice of seedlings in this field trial of seedlings divided into two phases. The first period sown on May 12, June 11 transplanted rice seedling field in the following season, intercropping on both sides of the seedbed. Tian Jing seedling age 31, 6-inch high seedlings, nodules. Tian Jing and rice seedlings symbiosis for 40 days. For exploration
