摘  要:
1985~1989年在海城市棕壤和草甸土上,应用现代回归设计,设置了94个玉米氮磷肥料田间试验,配出了12个有代表性的肥料效应方程,探讨了土壤类型、土壤肥力水平以及有机肥料用量对肥料效应的影响。编制出两套电算程序,应用计算机计算出在资金和肥源充足和不足两种情况下的玉米最佳施肥方案供农户使用。4年来,应用推荐的配方施肥面积累计达166万亩,增产玉米5.5万吨,增收4300万元。

摘  要:
From 1985 to 1989,with modern regression design,94 field fertilizer experiments for Zea mays were arranged in browm soil and grassland in Haicheng.12 representative fertilizer effect equation were derived.The influences of soiltypes,level of fertility and the amount of organic ferti- lizer used on the inorganic fertilizer's effect were studied.A definite computer program is composed,with which the best distribution,ration and quality about fertilizer are selected in the conditions with or without sufficent fund.During the past 4 years,according to this design,1660000 mu of corn field were fertilized and the output of corn increased by 55000000kg,equal to 43000000 yuan.
