环渤海雨养旱作区冬小麦起垄覆膜侧播种植模式研究
Study on the Furrow Planting Modes with Ridge Film Mulching of the Winter Wheat in the Rain-fed Areas around Bohai
摘要
Abstract
The study was carried out to explore the optimum planting mode of ridge film mulching of winter wheat around Bohai.During the growing seasons in 2014-2015 and 2015-2016,'Cangmai 6005'was used as test material to study the group structure,dry matter accumulation,leaf area index,yield and yield components of winter wheat by using six kinds of planting patterns.The results showed that the yields of A2 (Ridge covered film,ridge width of 45 cm,ditch 45 cm,ditch within the species 4 lines,spacing 15 cm) were improved by 68.48 % in the 2014-2015 season and 56.18% in the 2015 -2016 season respectively,which were significantly higher than that of CK.The number of panicles was 639.30 × 104/ hm2,which was 13.28% higher than that of CK.The average number of grains per spike was 23.35 g,which was 13.28% higher than that of CK.The highest 1000-grain weight of A2 was 40.28 g,which was significantly higher than that of CK (7.44%).The highest spike rate of A2 was 59.91%,which was 14.11% higher than that of CK.The dry matter quality of A2 in mature period was highest,which was 26.95% higher than that of CK,and the difference was significant.The LAI of A2 was 6.74 at booting stage,which was16.84% higher than that of CK,and the change of LAI was mild in later period.In summary,the pattern of planting structure was reasonable and the yield effect was remarkable,which was suitable for the rain and drought farming area of the low plains around Bohai to promote the application.关键词
