| 摘 要： | 轻简化和机械化是现代农业发展的趋势。本文于2 0 1 3 —2 0 1 5 年连续进行了常规人工栽插、机械直播、机械栽插等3种栽培模式对水稻主要害虫种群发生动态的影响研究,旨在为农业轻简、机械化模式的进一步推广提供依据。结果表明,3种栽培模式对稻飞虱、稻纵卷叶螟种群发生的影响差异不明显。比较3 种栽培模式下的水稻螟虫(二化螟为主, 大螟较少) 发生和为害可知,机械直播田的螟虫前期株为害率较高,且后期仍维持较高的为害率,明显高于人工栽插和机械插秧田(p<0.05)。分析原因,很可能是机械直播水稻暴露在大田的时间要稍长于栽插模式(机械插秧和人工栽插),有利于二化螟的提前入田为害。因此在推广机械直播时,应考虑调整播期,尽可能地避开或减少螟虫为害。

Effect of Rice Cultivation Modes on the Main Pests Population Dynamics |
| |
| Abstract: | To clarify the effects of different cultivation modes on the main pests population dynamics in rice, and to provide a theoretical basis for light & simplified cultivation modes, from 2013 to 2015, field positioning tests were adopted to investigate the occurrence number of the main pests population with three cultivation modes in the rice growth season. SPSS 21.0 data analysis software was used to analyze the survey data, and the significant differences among the three cultivation modes were compared. The results showed that, the three cultivation modes had no significant influence on the occurrence of rice planthoppers (Nilaparvata lugens and Sogatella furcifera) and rice leaf roller (Cnaphalocrocis medinalis). By comparing the occurrence and damage of rice stem borers (Sesamia inferens was dominating and Chilo suppressalis was rare), the damage rate of rice stem borers in the field of mechanical direct sowing was relatively high, and remained high at the later stage, which was obviously higher than that of artificial transplanting and machine transplanting (P<0.05). It suggested that when popularizing mechanical direct sowing, we should adjust the sowing time reasonably to avoid the damage of rice stem borers. |
