摘要
研究渗灌管不同管间距处理对番茄植株生长和产量形成的影响 ,找出适合温室番茄栽培的渗灌管埋设深度的处理方式。温室番茄栽培渗灌试验表明 ,渗灌管管间距离 5 0 cm的处理方式可使土壤容重降低 0 .16 3g· cm- 3,总孔隙度增加 5 .378% ;番茄株高、株幅和茎粗分别增加 14 .33cm、4 .5 9cm和 0 .0 81cm;前期、中期和总产量分别增产 2 6 3.4 1% ,76 .99%和 4 6 .0 8%。
The infiltration irrigation technology study was conducted on tomato cultivation in greenhouse,the results show that the treatment which infiltration pipe was placed in distance of 50 cm can reducing soil bulk density 0.163 g·cm -3 and increasing soil porosity,which have effects of increasing plant growth and tomato yield
