摘要
2002年在宁夏西吉县对旱地春小麦膜侧栽培技术及其膜下加盖秸秆和单纯秸秆覆盖栽培技术进行了试验研究。结果表明:这些技术措施都具有明显的节水增效作用,以膜下加盖秸秆效果最为突出。它不仅能改善土壤物理化学性状,平抑地温,提高降水利用率,而且增强了植株活力和群体动态发育,抑制田间杂草,增加土壤有机质,保证了农田土壤肥力的可持续提高。
The trials for dry-land spring wheat cultivation under film marginalized covering, film-marginalized covering with chopped stalks and just chopped stalks covering were conducted in Xiji county in Ningxia in 2002. The results showed that all the covering techniques had significant water-saving effects, especially for film marginalized covering with chopped stalks. The covering techniques not only improve soil physical and chemical characters, alleviate the ground temperature change and increase the utility of rainfall, but also enhance the growth vigor of individual plants and the dynamic development of plant colong, inhibit the growth of weeds, increase the content of soil organic matter, and ensure the sustainable development of soil fertility maintaining.
