栽培方式对田间小气候及越夏番茄生长与产量的影响

遮荫栽培与间作栽培表现为株高较高,茎粗较细,生长发育较露地栽培延迟。遮荫栽培由于降低高温季节的温度,改善了环境条件,提高坐果率,促进果实的膨大,因此最终产量以遮荫栽培为高,达6369.3kg/667m2;虽然间作栽培也可改善高温季节的温光条件,但因后期玉米与番茄生长的矛盾突出,影响了番茄的生长,因此间作栽培的产量仅为4770.7kg/667m2,比露地栽培产量5806.2kg/667m2低17.83%。

Effects of Cultivation Patterns on Microclimate, Growth and Yield of Over-summer Tomatoes

Different cultivation patterns of over-summer tomatoes leaded to different microclimate in field, so cultivation patterns influenced the growth and development. Tomatoes by intercropped and shaded cultivation showed high plant height, slim shoot and large leaf area, though the biological production was high, but plant was spindling, development was delayed, economical coefficient was lower, the yield of tomatoes cultivated by shading field, 6369.3kg/667m~2, was highest among the three cultivation patterns, and the yield of tomatoes cultivated by opening and intercropping was only 5806.2 and 4770.7kg/667 m~2, respectively.
