温湿度控制黄瓜幼苗徒长的效果研究

目的]研究温湿度控制黄瓜幼苗徒长的效果,以期达到壮苗的目的。方法]以不同温湿度对连栋大棚黄瓜幼苗进行处理,通过物理方法调控黄瓜幼苗生长,研究温湿度控制黄瓜幼苗徒长的效果。结果]地表下20 cm土层的2个处理黄瓜幼苗壮苗指数最高,可以通过降低地温来调控黄瓜幼苗的徒长;由于水分的调控与温度和光照密切相关,不宜控制,尽量避免采取控水措施来调控幼苗的生长。结论]该研究为采用更多的物理方法调控蔬菜幼苗生长研究提供理论依据。

Effect of Combination of Temperature and Humidity on Spindling of Cucumber Seedlings

Objective] To study effect of combination of temperature and humidity on spindling of cucumber seedlings,in order to achieve the strong seedling.Method] This experiment was conducted by physical methods in different temperature and humidity to study effects on the spindling of cucumber seedling.Result] The cucumber seedlings in-20 cm soil layer showed good results in robust seedling index,so measures on reducing the temperature were adopted to regulate the moderate growth of cucumber seedlings.Due to moisture control was closely related to the temperature and illumination,therefore moisture control measures weren't taken to control the growth of seedling.Conclusion]The study provides the theory basis for research on regulation of vegetable seedling growth by more physical method.
