【摘要】 本试验采用四因素二次通用旋转组合回归设计方法．对早春大棚茄子的产量与施肥整枝、密度、激素的关系进行了定量研究，建立了茄子产量与四因素的回归模式，分析了各因素之间的相互效应得出了本试验条件下 ６６６ ｍ ２ 产量大于 ３０００ ｋｇ 时，四因素的合理指标是：激素２．４－ Ｄ 用量为 ２４．２～２５．９／ｍ ｇ／ｋｇ、施肥量 ２５．２～２６．７ ｋｇ／６６６ｍ ２ 次、整枝 ６．９～７．５ 果／株、密度 ６０６３～６３６１ 株／６６６ ｍ ２ ．更多还原

【Abstract】 The experiment takes twice in common use turning association′s pegressive design of four factors.The method is that,to the relations among manure,density,hormone and pruning with output of eggplant in the big shed in early spring.We took quantitative analyses,built the regressive design between output of eggplant and the four factors,and analysed the effect of the factors.At last,we drew a conclusion that under the condition of the experiment,while output of out yields 3 000 kg per 666 m 2,suitable quantitative targets of the four factors as follows,Hormone of 2,4 D is 24.2~25.9 mg/kg.Manure is 25.2~26.7 kg/666 m 2/time.Pruned branches is 6.9~7.5 branches/plant.Density is 6 063~6 361 plants/666 m 2.更多还原
