1994~1996年,在山西浮山以露地条播等为对照,就冬小麦地膜覆盖穴播技术进行了研究。结果表明:全生育期地膜覆盖穴播技术在冬前、拔节期之前有较好的增温效果,有效地促进了小麦生育进程,延长了幼穗分化时间,使单株分蘖、次生根、绿叶数优于对照;在生长中后期有效利用深层水,使水分生产效率较对照提高0.11kg/mm,较好地协调了高产小麦水热规律需求,达到小麦公顷产量4521.0kg。该项技术有效地改善了半干旱地区冬小麦水热环境,是半干旱地区冬小麦实现高产稳产的一项战略性措施。
1994-1996, in Shanxi Fushan open field planted as a control, the winter wheat film mulching Bunch technology. The results showed that the plastic film mulching and sowing technology in the whole growth period had better warming effect before winter and jointing stage, which effectively promoted the process of wheat growth and prolonged the differentiation of young spikes. The tillering, secondary roots, green leaf number Which was better than the control. The effective use of deep water in the middle and late growth stage increased the water production efficiency by 0.11 kg / mm compared with that of the control. The demand of hydrothermal regulation of high yield wheat was well coordinated and the yield of wheat ha was 4521.0 kg. The technology effectively improves the hydrothermal environment of winter wheat in semi-arid area and is a strategic measure to achieve high and stable winter wheat yield in semi-arid area.
