In order to implement the great call of Chairman Mao’s Agricultural Learning Dazhai and seek ways to solve the problem of Ziyunying seed by self-reliance, I carried out the leave-cultivation experiment of Ziyunyin. The experiment was divided into two groups, one is the autumn sugarcane species of milk vetch species, the second is the paddy milk vetch leave species. The test results showed that 97.4 kg per mu of seeds were planted in the autumn sugarcane, 67.3 kg per mu of paddy fields. Test after 1. Autumn sugarcane seedlings of Astragalus species test field area of 1.02 acres, the soil is shallow soil, medium fertility sandy loam, before the medium-sized rice. After the plow was tidy, sugarcane was sown on September 28, 1973, with a variety of 57/423 and a row spacing of 3.5 feet. Single-sowing of double-sprouts was used with 1700 kg per mu.
