覆膜栽培花生,能增温、保墒、促进养分分解,改善土壤理化性状和田间小气候,加快花生生长发育,是提高花生产量的有效新措施。多年试验及生产实践证明,“徐州68—4”适宜在黄、淮、海流域及辽宁省南部北方花生产区的中肥以上地种植,尤其在覆膜栽培条件下,更能发挥它耐肥水,抗倒伏,果大,果多,果饱的丰产性能,易创高产。据山东省1982年139处
It is an effective new measure to increase the yield of peanut by cultivating peanut with the ability of warming, preserving soil moisture, promoting nutrient decomposition, improving soil physical and chemical properties and microclimate in the field and accelerating the growth and development of peanut. Years of trial and production practice have proved that “Xuzhou 68-4” is suitable for planting above medium-sized fertilizers in the Yellow River, Huaihe River Basin and northern flower-producing area in southern Liaoning Province, especially under the condition of film mulching cultivation, , Lodging, fruit, fruit and more fruit full of high yield performance, easy to hit high yield.
