不同覆膜方式对干旱地区胡麻水分利用和产量的影响

Effects of Different Film Mulching Methods onWater Use and Yield of Flax in Arid Areas

为了探明不同覆膜栽培模式对干旱地区胡麻根系水分动态分布及其产量的影响,本试验以露地条播为对照(CK),对2种栽培方式(全膜覆土穴播、膜侧条播)下胡麻试验田土壤水分、根系分布、水分利用效率和产量进行研究。结果表明:不同时期全膜穴播下土壤水分相对较高;随着胡麻的生长发育,主根也逐渐增大。全膜覆盖优于其他覆膜方式,适宜于在干旱地区推广应用。

In order to find out the effect of different film mulching cultivation modes on the dynamic distribution of root water and its yield of flax in arid areas,the experiment is conducted to study the soil water,root distribution,water use efficiency and yield of flax experimental field under two cultivation modes(full film mulching and hole sowing,film side drilling),with open field drilling as the control(CK).The results show that the soil moisture under mulching is relatively high in different periods.With the growth and development of flax,the main root also gradually increased.Full film covering is superior to other film covering methods,and is suitable for popularization and application in arid areas.
