播期对水稻生育期·产质量和温光资源利用的影响
Effects of Sowing Date on the Growth Period,Yield Quality and Utilization of Temperature and Light Resources of Different Rice Varieties
摘要
Abstract
[Objective]To investigate the effects of sowing date on the growth period,yield,quality and utilization of temperature and light resources of different rice varieties in southern Henan Province.[Method]Xinjing 1787,Jingyou 7699,Nanjing 5718 and Xinliangyou 1319 were used as test materials,and the experiments were carried out at the experimental base of Xinyang Academy of Agricultural Sciences in 2020 and 2021.[Result]With the delay of sowing date,the growth period of different varieties was shortened,and the utilization rate of ef-fective accumulated temperature and sunshine hours of each variety showed a decreasing trend.With the delay of sowing date,the rate of brown rice,white rice and finished rice increased first and then decreased,but the peak value of different varieties was different.The chalki-ness and chalkiness grain rate showed a decrease trend in general,and the grain type was stable.[Conclusion]Xinjing 1787 and Jingyou 7699 should be sown in the third stage(May 16),Nanjing 5718 should be sown in the fourth stage(May 26),and Xinliangyou 1319 should be sown in the first stage(April 26).关键词
