以世界冠军和麻辣三道筋等品种为试材,通过5年品种对比试验,研究了降水和灌排水对田间生态环境、甜椒生育、抗性和产量的影响,以及调节生态环境的关键时期。试验结果证明:均匀降水和及时灌排水能改善甜椒田间的综合生态环境;旺盛发棵期和恢复生长期是调节生态环境的关键时期;品种特性和当年田间生态环境决定了当年种体长势和抗性,而病毒病等病害和落叶轻重取决于秧体的抗性,甜椒产量分布和总产量高低受这些因素的共同影响。
Taking five world championships and three spikes as test materials, the effects of precipitation and irrigation on field environment, sweet pepper growth, resistance and yield as well as the key period of ecological environment adjustment were studied through five years of comparative experiments. The results showed that even precipitation and timely irrigation can improve the comprehensive ecological environment in sweet pepper field. The vigorous growth stage and the recovery growth stage are the key period for ecological environment adjustment. The variety characteristics and the current ecological environment in the field determine the growing status and Resistance, and diseases such as viral diseases and the severity of deciduous leaves depend on the resistance of seedlings. The distribution of sweet pepper and the level of total yield are all affected by these factors.
