休闲期深翻覆盖对旱地小麦土壤水分运行及产量与品质形成的影响
Effect of deep plowing and plastic film mulching in fallow period on soil water storage and wheat grain yield and quality
摘要
Abstract
In order to utilize precipitation in fallow period ,and preserve soil water ,a field experiment was carried out to study effect on soil water storage ,yield ,and quality formation of two treatments using water-permeability plastic membrane (WPM) and liquid film (LM) after deep plowing in fallow period in Wenxi of Shanxi Province ,with the aim of exploring an effective way of preserving the soil moisture in dryland wheat .Results showed that the combination of deep plowing and plastic film mulching increased 100 ~ 300 cm soil water storage until booting stage .It added 0 ~ 300 cm total water storage from pre-sowing to booting stage ,and this promoting effect of storing water lasted until flowering stage ,with WPM being better than other treatments .Spike number ,actual yield ,and grain protein content increased significantly at 45 d after harvest in fallow period .Furthermore ,80 ~ 200 cm in pre-sowing water storage was related to spike number and grain yield .120 ~ 300 cm water storage in pre-sowing and anthesis was related to grain protein content and yield .In conclusion ,deep plowing in combination with WPM in fallow period had marked effect on water storage preservation ,thereby increasing wheat yield and quality .关键词
