我场1970年开始搞水稻卷秧栽培时,由于育秧技术不过关,育出的秧苗有好、有坏,我们就试着把“好”、“坏”秧苗分开插,“好”的秧苗按每穴8～10株插上,“不好”的黄瘦秧苗按几十株一大簇插上,结果发现,小簇插的“好秧”返青慢,生长差;而大簇插的“坏秧”反而返青快,生长好。这一新的发现给了我们很大启发,于是我们在1971～1972年就扩大大簇插秧试验,又发现大簇插秧容易保苗,而且插秧工效高,质量好,在盐碱地上它比传统的小簇插秧能增产20％左右,在土壤盐碱大的情况下,可以成倍增产。1973年我们在多年撩荒的盐碱地上推广了430亩水稻大簇插秧,平均亩产超过500斤;1974年又在这430亩重茬稻田搞大簇插秧,平均亩产达600斤以上。
When we began to cultivate rice in the rice spinning in 1970, we tried to separate the “good” and “bad” seedlings by planting the seedlings well or badly, Each hole 8 to 10 plugged in, “bad” yellow thin seedlings by dozens of strains of a large cluster plugged in, the results found that the small cluster inserted “good seedling” back green, poor growth; Bad seedling "But back to green fast, good growth. This new discovery gave us a great inspiration, so we expanded the large-scale transplanting experiments from 1971 to 1972 and found that the large cluster of transplanting is easy to seedlings, and the transplanting efficiency, good quality, it is smaller than the traditional small in saline-alkali soil Cluster transplanting can increase about 20%, in the case of large soil salinity, you can double production. In 1973, we promoted 430 mu of large-sized rice transplanting seedlings on saline-alkali soil for many years, with an average per-mu yield of more than 500 kilos. In 1974, we conducted a large cluster of transplanting rice seedlings on the 430 mu of stubble paddy fields, with an average yield of over 600 kilos per mu.
