本文探讨了垄式、槽式和袋式３种基质栽培床对春番茄根际温度、耗水量、植株生长及产量的影响。早春植株较小，阳光照射栽培床，以致垄培能明显提高根际温度，促进生长。入夏后，植株生长旺盛，冠层遮荫，栽培床结构对根际温度影响不大。春番茄自定植到拉秧的１１０天中，垄式栽培共耗水７１Ｌ／株，比其他处理节水２０～３０％。垄式栽培的早期产量为２７７１ｋｇ／６６６．７ｍ２，分别比其他处理高２６％，３０％。垄式、槽式和袋式栽培每６６６．７ｍ２的总产量分别为４１０９、３７７８和３２５０ｋｇ
In this paper, the effects of ridge, trough and bagged three kinds of substrate beds on rhizosphere temperature, water consumption, plant growth and yield of spring tomato were studied. Small plants in early spring, the sun shines on the cultivation bed, so ridge cultivation can significantly improve the rhizosphere temperature and promote growth. After the summer, the plants grow vigorously, the canopy shade and the cultivation bed structure have little effect on the rhizosphere temperature. Spring planting tomato plantation to pull the seedlings in 110 days, ridge cultivation of water consumption 71L / strain, saving 20-30% more than other treatments. The early yield of ridge cultivation was 2771kg / 666.7m2, which was respectively 26% and 30% higher than other treatments. Ridge, trough and bag cultivation per 666.7m2 of the total output were 4109,3778 and 3250kg
