河南省项城县地处淮北平原,沙颍河南岸。砂姜黑土占全县总面积的51.7％。主要作物有小麦、大豆、红薯等,从未种过花生,砂姜黑土究竟能否种花生?产量又如何?为探讨这个问题,我们在1979年小面积试种花生获得成功,亩产300多斤。1980年以后,根据砂姜黑土结构不良、易涝易旱等不利因素,采取起埂种植、增磷补氮、根外追肥等技术措施,花生亩产提高到600斤左右。1982年花生丰产田,亩产达800斤。实践
Xiangcheng County, Henan Province is located in Huaibei Plain, south bank of Shaying River. Shajiang black soil accounted for 51.7% of the total area of the county. The main crops are wheat, soybeans, sweet potatoes, etc., have never been planted peanuts, sand Jiang black soil whether the peanut? Yield to explore this issue, we in 1979 small area planted peanut success, more than 300 per mu jin. After 1980, according to unfavorable factors such as poor structure and easy waterlogging and drought-prone of shajiang black soil, technical measures such as planting and planting, increasing phosphorus and nitrogen, and dressing outside the root were adopted. The peanut mu production increased to about 600 kg. 1982 peanut yield fields, per mu up to 800 pounds. practice
