插秧机秧爪结构对秧苗栽插质量的影响

本文研究了机插秧的秧爪结构、秧龄、株距、秧盘形式和播种量等参数对秧苗栽插质量“漂秧率”、“漏插率”和“伤秧率”(以下简称“三率”)的影响.结果表明:秧爪结构对秧苗栽插质量“三率”影响特别显著,秧龄对漂秧率的影响特别显著,其他看不出影响；株距对漂秧率和漏插率有一定影响,其他看不出影响；播种量对漂秧率有一定影响,其他看不出影响；秧盘形式对伤秧率有一定影响,其他看不出影响.且钢板秧爪结构插秧机的栽插质量明显优于钢针秧爪结构插秧机的栽插质量.钢板秧爪结构插秧机对秧苗栽插质量影响顺序如下:秧爪结构＞秧龄＞株距＞秧盘＞播种量.

Effects of Seedling Claw Structure on Transplanting Quality by Mechanical Transplanting

In this paper,the effects of seedling claw structure,seedling tray,seedling age,inter plant distance and sowing rates on transplanting quality as seedling floating rate,sowing leakage rate and seedling injury rate(referring to as the ’three rate’) were studied.The results showed that seedling claw structure had the significant effect on ’three rate’,and the seedling age had the most significant effect on seedling floating rate;inter plant distance had the effect on seedling floating rate and sowing leakage;sowing quantity had effect on seedling floating rate;the steel plate seedling claw structure had effect on seedling injury rate.The transplanting quality of rice transplanter with steel plate seedling claw structure was superior to rice transplanter with steel needle seedling claw structure.The sequence of significant effects on transplanting quality ’three rate’ were in following range: seedling claw structure> seedling age>inter plant distance> seedling tray> sowing rates.
