播期对甜加糯鲜食玉米品种冀糯175生育期以及产量和品质的影响
Effects of Sowing Date on Growth Duration,Yield,and Quality of Sweet Waxy Fresh Eating Maize Variety Jinuo 175
摘要
Abstract
To investigate the effects of sowing date on growth period,yield,quality,and disease resistance of the new sweet-waxy fresh-eating maize variety Jinuo 175,a single-factor field experiment was conducted.Treatments with different sowing dates were set in 2023 to 2024 to compare the differences in growth duration,yield,quality traits,and disease incidence under various sowing dates,and a comprehensive e-valuation was carried out.The results showed that the whole growth period generally increased with the de-lay of sowing.In 2024,the whole growth period of early sowing treatment(May)was 74-84 days,and that of late sowing treatment(July)was 84-89 days.In 2023,differences in yield and quality among sow-ing dates were relatively small,with June 20 being the optimal date,which produced a yield of 14 679 kg/hm2 and a quality score of 89.5.In the 2024 trial,sowing from June 20 and July 20 generally exhibited better agronomic traits,yield,and quality;among them,July 10 produced the highest yield(17 934 kg/hm2)and the highest quality score(89 points).In terms of disease resistance,Jinuo 175 showed stable resistance to stalk rot,head smut,ear rot and common smut.Northern leaf blight,southern leaf blight and virus diseases(maize dwarf mosaic virus and rough dwarf virus)were markedly affected by sowing date.Premature sowing(May 11)caused northern leaf blight reaching grade 5 and the occurrence of virus diseases,whereas excessively late sowing(July 30)resulted in southern leaf blight at grade 3.Sowing from late June to mid-July resulted in the lightest disease incidence and the best comprehensive resistance.In summary,the suitable sowing period for Jinuo 175 in ecological zones similar to Hebei Province is late June to early July(around June 30-July 10).Sowing in this period can realize high yield,good fresh-eating quality and low disease risk,and appropriate adjustments can be made in production according to annual climatic conditions.The results can providea theoretical basis and technical support for high-yield,high-quality and disease-resistant cultivation of Jinuo 175.关键词
