播期对荆门地区甘蓝新品种中甘101生长发育及产量的影响

为研究不同播期对中熟秋甘蓝新品种中甘101在荆门地区收获期及产量的影响,设置5个播种期进行对比试验。结果表明:8月6日和8月13日播种的甘蓝产量最高,但生育期较长;7月16日播种的甘蓝生育期最短,但产量最低;7月23日和7月30日播种的结球甘蓝农艺性状大致相同,能够在相对较短的生育期下获得比较稳定的产量,因此认为7月23日—8月5日为秋甘蓝中甘101在荆门地区的适宜播期。

Effect of Different Sowing Dates on Maturity and Yield of 'Zhonggan 101' in Jingmen

Abstract: For discussing the sowing dates of ''Zhonggan 101'' in Jingmen, which could affect the growth date and the yield of ''Zhonggan 101'', five sowing dates were set up for comparative experiments. The results showed that the highest yield and long growth date of ''Zhonggan 101'' were planted on August 6 and August 13. The planting period of cabbage that was planted on July 16 was the shortest, but the yield was the lowest. The agronomic characters of cabbage sowed on July 23 and July 30 were approximately the same, and cabbage with relatively stable yield could be obtained in a relatively short growth date. July 23 to August 5 was considered as the suitable sowing date for autumn cabbage ''Zhonggan 101'' in Jingmen.
