加工番茄长红在“宽垄不翻秧”模式下的高效栽培研究

通过四因素(密度、氮肥、磷肥、钾肥)三水平(三个密度水平、三个氮肥水平、三个磷肥水平、三个钾肥水平)的高效栽培技术田间正交试验,统计分析结果显示长红在“宽垄不翻秧”栽培模式下,对其产量作用影响的参试因子按其大小顺序为:氮肥>密度>磷肥>钾肥,并且组合因子在:种植株数为2 500株/667m2,尿素为20~40 kg/667m2,三料磷肥15~30 kg/667m2,硫酸钾肥10~15 kg/667m2时,加工番茄杂交一代品种长红在“宽垄不翻秧”栽培模式下发挥的增产、增效潜力较为理想,在此范围内的具体需肥数量,需进一步研究。

The Research of Effective Technological Planting by"Wide Row and Unmoving Vine" Planting Model of Changhong

According to the orthogonal design of the effective technological planting trial which is designed by four factors(Density,N-fertilizer,P-fertilizer,K-fertilizer)and three levels(Three density level,three N-fertilizer level ,three P-fertilizer level,three K-fertilizer level),the analysis statistic result showed that the sequence of factor affecting yield is as follows:N-fertilizer> Density> P-fertilizer> K-fertilizer.Also the F_1 processing tomato variety planted by "wide row and unmoving vine" model expresses better yield-increases efficiency,especially when factors are:2 500 plant/667m~2,N-fertilizer 20～40 kg/667m~2 P-fertilizer 15～30 kg/667m~2 and K-fertilizer 10～15 kg/667m~2.
