| 摘 要： | 为了探索河套灌区玉米不覆膜滴灌对其产量及土壤理化性质的影响,2015年在内蒙古河套灌区中游开展了玉米不覆膜滴灌试验研究。定株测试玉米不同生育期的株高、茎粗和产量对比分析,得出:在苗期和拔节期,覆膜滴灌玉米株高和茎粗显著优于不覆膜处理,抽雄期后对玉米植株生长性状影响差异不显著,但不覆膜处理玉米产量较覆膜处理下降了15.87%;在玉米苗期,0~40cm耕层土壤,覆膜处理较不覆膜处理土壤温度平均增加了5.62℃。土壤耕层温度的提高为玉米生长提高良好的土壤环境。

Research on the Influence of mulch Drip Irrigation of Maize Growth and Seeding Soil Temperature |

| Abstract: | The experiment of mulch-drip irrigation and no-mulch drip irrigation were carried out in the Hetao irrigation district in 2015,to explore the influence of no-mulch drip irrigation on maize growth and yield and soil physical properties.Based on the obser-vation and analysis of soil temperature,maize growth characters and yields,its showed that maize plant height,stem diameter of mulch-dirp irrigation was significantly superior to that of no-mulching treatment,at seedling stage and jointing stage.But after tease-ling stage,maize plant traits were not so effective as before.Compared mulch drip irrigation maize yields with no-mulch drip irriga-tion fell 15.87%.In the maize seedling stage,soil daily average temperature was enhanced through mulch film by 5.62 ℃,compared to no-mulch drip irrigation(0~40 cm).Plastic film mulching can effectively improve the soil temperature in maize growth period,its can provide a more favorable environment for maize growth. |
