1977年我们结合教学实习,在南郑县石拱公社爱国13队及强国4队共种杂交水稻14.1亩,获得了亩产1,165斤的较高产量,其中2.7亩高产田平均亩产达到了1,351.5斤。另外还进行了秧苗素质、密、肥等试验。通过一年实践,我们对栽培杂交水稻有以下几点初步体会: 一、播期要适时,培育健壮秧杂交组合南优2号生育期较长,两年试种结果,全生育期均在150天以上(1976年158天,1977年151天),从播种至齐穗约120天左右。1977年于4月21日播种,秧
In 1977, we combined teaching practice with a total output of 14.1 mu of hybrid rice in Shigong commune of Nanzheng County, Shuguo commune, 13 teams and 4 strong teams, and obtained a high output of 1,165 kg per mu. The average yield per mu of 2.7 mu of high yield land reached 1,351.5 jin. In addition also carried out the quality of seedlings, dense, fat and other tests. Through a year of practice, we have some initial experiences on the cultivation of hybrid rice: First, the sowing time to cultivate a strong seedling hybrid combination Nan You 2 longer growth period, two years of test results, the whole growth period of 150 Days (158 days in 1976, 151 days in 1977), about 120 days from sowing to full spawning. 1977 on April 21 sowing, seedlings
