以鲜食糯玉米品种“中糯1号”为试验材料,设3月20日、4月5日、4月20日、5月20日、6月20日、7月20日和8月5日等7个播期(其中,3月20日和4月5日为地膜覆盖播种,其他播期均为露天播种),通过考察各个播期的生育进程、植株性状、穗部性状、抗逆性以及产量性状,并对经济效益进行分析,得出结论为3月20日-4月5日覆膜播种和4月20日-7月20日露天播种均能正常采收,8月5日播种的未能正常采收;5月20日和7月20日露天播种病害发生率较高,产量和经济效益较低。
The fresh waxy corn variety “Zhongnuo 1 ” was used as the experimental material, which was set on March 20, April 5, April 20, May 20, June 20, July 20 and 8 (Including March 20 and April 5 for mulching and other sowing dates for open-sowing). Through studying the sowing process, plant traits, ear traits, Stress resistance and yield traits, and analyzed the economic benefits, concluded that from March 20th to April 5th planting seeding and April 20-July 20 open seeding can be normally harvested August On the 5th, planting failed to recover normally. On May 20 and July 20, there was a higher incidence of open-sowing diseases and lower yield and economic benefits.
