摘要
采用"3414"不完全施肥试验方案设计,研究单种玉米在淡灰钙土条件下的土壤供肥量、作物吸收养分量、土壤养分丰缺指标等参数,提出相应的推荐施肥量。结果表明:在该土壤类型条件下单种玉米施纯N 330 kg/hm2、P2O590 kg/hm2、K2O 90 kg/hm2,玉米可获得较好的经济产量。
Some parameters such as soil nutrient-supplying,crop nutrient uptake and soil nutrient？abundance and deficiency indices with corn singly grown on light sierozem were researched adopting ＂3414＂ incomplete test design.The soil nutrient？abundance and deficiency indices were established and relevant recommended fertilization quantities were put forward.The result shows that a relatively high economic yield could be achieved with corn singly grown on the soil of this type and applying pure nitrogen fertilizer 330 kg/hm2,P2O5 90kg/hm2 and K2O 90kg/hm2.
