摘要
宁南山区旱地玉米 ,采取覆膜沟穴播种植 ,施肥水平为 N150 P150 ,并选用旱地宝+锌肥 +锰肥浸种可获得最高的产量和最大的水分利用效率 ;覆膜沟穴播比覆膜穴播增产7.75% ,水分利用效率提高 5.
The test results show that in the dry land in south area of Ningia, applying the technique of plastic film mulching and hole seeding in furrow of Maize, with the level of fertilizer N 150 P 150 and seeds soaked in the liquid of HDB drought resistance, Zn fertilizer and Mn fertilizer and medicament for keeping water, can increase the yield of maize up to 7.75% and improve the water use efficiency up to 5.1%.
