摘要
试验研究不同降湿处理对温室番茄作物生长及养分积累的影响结果表明,经不同降湿处理后番茄植株株型变高、基茎加粗,与对照相比均达显著水平;地下热循环冷凝显著增加植株花序数、花数及果数;2个降湿处理植株叶片数、落花数和蕾数以及植株体内有机碳、Ca、Mg养分均与对照无显著差异;而全N、全P、全K 3种养分则存在不同程度差异。不同降湿处理对番茄植株各器官干物质分配率亦无显著影响。
The effects of different dehumidified treatments on tomato growth and nutrients accumulation inside greenhouses were studied. The results show that the tomato plant becomes more higher, the cauline diameter becomes more bigger,and marked differences exist compared to the CK,inflorescence number, flower number, fruit number are increased markedly after condensation by underground heat-circulation, but leaf number, bud number, shatter number in addition to organic C,Ca and Mg is contrary after two different dehumidified treatments. While the differences exist including total N,total P,total K after two dehumidified treatments. No marked influences on the assignment rate of tomato dry matter exist after the two treatments.
