摘要:

为满足长三角地区对鲜食玉米的周年需求,本文选用浙江省主导玉米品种浙糯玉16和浙甜11为材料,分两期在不同土壤肥力条件下研究了宽窄行种植和吐丝期喷施油菜素内酯对夏季高温条件下鲜食玉米农艺性状和产量的影响。结果表明,与等行距(行距70 cm)种植相比,宽窄行(宽行距70 cm、窄行距50 cm)种植提高了第二期2个品种的穗粗、单穗重和产量。与喷施清水相比,外源喷施0.05 g·L-1油菜素内酯提高了吐丝期浙糯玉16的穗长、单穗重和产量以及浙甜11的产量,同时提高了第二期2个品种籽粒的粗淀粉、直链淀粉和支链淀粉含量。本研究认为宽窄行种植和吐丝期喷施油菜素内酯均可有效缓解高温对鲜食玉米产量的影响,是浙江省鲜食玉米越夏栽培的有效技术手段。

Abstract:

To meet the annual demand for fresh maize in the Yangtze River Delta region,this study selected leading maize varieties Zhenuoyu 16 and Zhetian 11 in Zhejiang Province as materials,and studied the effects of wide and narrow row planting and spraying brassinolide during the silking stage on the agronomic traits and yield of fresh maize under high temperature conditions in summer at two stages under different soil fertility conditions. The results showed that compared with planting at equal row spacing(row spacing of 70 cm),planting in wide and narrow rows(wide row spacing of 70 cm and narrow row spacing of 50 cm)increased the ear diameter,single ear weight,and yield of the two varieties at the second stage. Compared with spraying water,exogenous application of 0.05 g·L-1 brassinolide during the silking stage increased the ear length,single ear weight,and yield of Zhenuoyu 16,as well as the yield of Zhetian 11. At the same time,it increased the contents of crude starch,amylose,and amylopectin in the seeds of the two varieties at the second stage. This study suggests that both wide and narrow row planting and spraying brassinolide during the silking stage can effectively alleviate the impact of high temperature on the yield of fresh maize,and are effective technical means for summer cultivation of fresh maize in Zhejiang Province.

Key words: fresh maize, high temperature in summer, wide and narrow rows, brassinolide, cultivation technique
