半免耕栽培对番茄生长的影响

为了探索半免耕栽培对番茄生长的影响,试验选用富贵6号为材料,通过测定传统栽培和半免耕栽培番茄的株高、茎鲜质量、叶片数及叶鲜质量等地上部营养生长和根系生物量、根的分布情况、根冠比等7个指标,进行对比分析,结果表明:(1)从定植至摘心期间,半免耕栽培番茄的株高、茎鲜质量、叶片数及叶鲜质量在各阶段均优于传统栽培番茄相应阶段的表现;摘心后,半免耕栽培番茄的茎鲜质量、叶片数及叶鲜质量与传统栽培的差异均达到显著水平,半免耕栽培优于传统栽培。(2)半免耕栽培番茄的根系生物量以及0~20 cm土层的根系生物量均高于传统栽培,根系分布明显偏于浅层。

Effects of Half No-tillage Cultivation on Tomato Growth

To explore the effect of half no-tillage cultivation on growth of tomato（ Solanum lycopersicum L.），this paper took‘Fugui No.6’ as test material and measured 7 indexes of above-ground part vegetable growth，including：plant height，weight of stems，number of blades，weight of leaves and root biomass，root distribution and root shoot ratio，respectively.Then comparative analysis was carried out between half no-tillage cultivation and traditional cultivation.Results showed as follows：（1） No matter from transplanting to removing the shoot apex，or after removing the shoot apex，the plant height，weight of stems，number of blade and leaf weight of tomato by half no-tillage cultivation were all significantly superior than that by traditional cultivation.（2） Root biomass of the whole plant and that between soil layers of 0 to 20 cm by half no-tillage cultivation was also superior to that by traditional cultivation，and the root distribution tended to shallow soil layer apparently.
