小窝密植是改进川西丘陵黄壤粘土地区传统窝播技术形成的优良播种方式。作法是:土地整细整平后,先用铁制开窝器开圆形小窝,深约1寸,直径约1.5寸,行距6寸,窝距3寸,每亩3.3万多窝,再按计划要求的每窝下种量下种,然后施用兑有氮素化肥的粪水,最后用整细的混有油饼粉和磷肥的堆厩肥盖种,不再覆土。小窝密植增产效果显著。5年试验结果,比窄行条播增产5.34—12.09％,示范推广结果比窄行条播
Small dense nest is to improve the traditional farming of yellow sand loess in western Sichuan hills formed a good sowing method. The practice is: After the land is leveled and flattened, the circular pit is opened with an iron pit opener, about 1 inch in depth, about 1.5 inches in diameter, 6 inches in row spacing and 3 inches in pit spacing, with over 33,000 cells per mu Under the plan requirements of each species of seed under the next species, and then applied to fertilize the manure with nitrogen fertilizer, and finally with a fine mixture of oil cake powder and phosphate fertilizer manure cover, no longer cover the soil. Small dense planting yield a significant effect. 5 years test results, increased than the narrow row sowing 5.34-12.09%, the results of demonstration and promotion of narrow row sowing
