旱地谷子全膜双垄沟覆盖穴播技术效应研究

旱地谷子全膜双垄沟覆盖穴播技术研究结果表明，在旱地采用秋季全膜双垄沟覆盖穴播栽培谷子，可明显的保住土壤水分、接纳无效降水，提高出苗率，促进幼苗健壮生长发育，增产增收效果显著。采用秋季全膜双垄覆盖春季沟穴播技术，谷子产量可达3909．09kg／hm^2，比露地种植增产46．7％，纯收入达到11743．5元／hm^2，较对照增加4176．0元／hm^2；其次为早春（顶凌）全膜双垄覆盖春季沟穴播技术，谷子产量达到3713．64kg／hm^2，较露地种植增产39．3％，纯收入达到10794．0元／hm^2，较对照增加3226．5元／hm^2。建议在谷子覆膜栽培上，重点选用秋季地膜覆盖和早春地膜覆盖技术，促进谷子增产增收。

A Study of Effect of Double Ridge Furrow Whole-mulching Hole Sowing Technology for Dryland Millet

A study of the effect of the double ridge furrow whole-mulching hole sowing technology for dryland millet was made. The result showed that growing millet on dryland adopting the double ridge furrow whole-mulching hole sowing tech- nology in autumn could keep soil moisture, receive invalid precipitation, increase the rate of emergence and promote seedling growth and the effects on yield and income increasing were significant, When the technology of the double ridge whole-mulching in autumn and furrow hole sowing in ispring was adopted the yield of millet could reach 3 909.09 kg/hm2, an increase by 46.7% compared with that of the open field cultivation, the net income reached 11 743.5 yuan /hm^2 ,an in- crease of 4 176.0 yuan/hm2 compared with that of the control. When the technology of the double ridge whole-mulching in early spring and furrow hole sowing in spring was adopted the yield of millet could reach 3 713.64 kg/hm^2, an increase by 39.3% compared with that of the open field cultivation, the net income reached 10 794.0 yuan/hm^2, an increase of 3 226.5 yuan/hm^2 compared with that of the control. It is suggested that for growing millet with film-mulching, the technology of the film-mulching in autumn and the film-mulching in early spring should be chosen to promote the yield increasing and the income increasing.
