摘要：

为延长鲜穗消费周期和甜糯玉米企业加工期，结合山西忻州当地种植习惯，试验集覆膜、沟垄作、宽窄行为一体的深沟覆膜播种方式，通过与当地使用最广泛的膜侧播种、膜上播种和裸地平作对比，得出以下结论。深沟覆膜形成了小温室，4月可提高土壤温度13.7%~22.4%，促进玉米早发快长，在玉米生长前期干物质积累显著高于其他播种方式，最终产量与其他播种方式无显著差异，但明显缩短了生育期，甜糯玉米采收时间可提前4~19 d，实现早播早收。

Abstract:

In order to extend the consumption cycle of fresh ears and the processing period of sweet-waxy corn enterprises, combined with the local planting habits in Xinzhou, Shanxi, a deep furrow mulching sowing method that integrates film mulching, furrow and ridge cultivation, and wide and narrow row was tested. By comparing it with the most widely used film side sowing, film top sowing, and bare land flat planting in local area, the following conclusions were drawn. Deep furrow film mulching formed a small greenhouse, which could increase the soil temperature by 13.73%-21.88% in April, and the higher accumulated temperature could promote the germination and growth of maize. The dry matter accumulation was significantly higher than that of other treatments in the early stage of maize growth. The final yield had no significant difference from other treatments, but the growth period was significantly shortened. The harvest time of sweet-waxy corn can be 4 to 19 days ahead of the schedule, so as to achieve early sowing and early harvest.

Key words: sweet-waxy maize, deep furrow film mulching, growth period, early sowing and early harvest
