豫西旱作区玉米再高产技术应用研究

选择抗旱品种、及时探墒播种、实施秸杆覆盖是旱作区夏玉米增产关键措施。通过试验选择抗旱品种浚单20,麦收后及时贴茬重楼探墒播种,麦秸杆覆盖于玉米田宽行内,充分利用自然降水,蓄水保墒,加上平衡施肥,可使旱作区玉米产量最高可达9000kg/hm2。

The dry farming area summer maize increases the production of key measure investigation and discussion

That the soil moisture choosing drought-resistant variety , exploring in time sows seeds , puts straw coverage into practice is that the dry farming area summer maize increases the production of key measure. By testing that the drought-resistant variety choosing dredges Shan 20, the wheat harvest queen highly values a building exploring the soil moisture sowing closely to batch in time , that the natural precipitation the wheat straw pole is covered fully utilizing in cornfield width line,stores water preserves the moisture of the soil, adds balance applying fertilizer, but uses dry farming area maize output most Gao Ke Da 9000 kilograms per hectare.
