冀西北高寒区地膜覆盖对小南瓜生育及水分利用效率的影响

The Effect of PIastic Film Mulch Cover on Growth and Development and Water Use Efficiency of Small Squash in the Northwest of Hebei Provinee

研究了地膜覆盖对旱砂地小南瓜生育特性和水分利用效率的影响。试验结果表明,地膜覆盖后,创造了适合于小南瓜生育的土壤温度和湿度条件,加快了其生育进程,单产量、单果鲜重和干重都优于对照,提高了对土壤水分的利用效率。

This paper studied the effect of plastic film mulch cover on growth and development and water use efficiency of small squash in the dryland. The result showed that plastic film mulch cover afforded a propar soil temperature and humidity for small squash which quickened its growth and development course. The treatment excelled the contrast in yield and fresh weight and dry weight. The water use efftciency of soil Was increased.
