2JC-500型自动嫁接机西瓜苗嫁接效果生产试验

Production test of 2JC-500 automatic grafting machine for watermelon

为了解2JC-500型自动嫁接机嫁接西瓜苗的生产效果及其影响因素,进行了西瓜机械嫁接育苗的生产试验,并测定了嫁接用苗形态对嫁接机嫁接效果的影响。试验结果表明,砧木瓠瓜苗子叶展开角小于45°、接穗西瓜苗胚轴弯曲和子叶不对称于胚轴的情况会分别显著地影响砧木机械打孔和砧穗对接的作业质量;当砧木子叶展开角大于45°,接穗西瓜苗胚轴不弯曲且子叶对称于胚轴时,机械嫁接育苗生产中嫁接机的嫁接成功率可大于90%,2JC-500型嫁接机作业生产率可达450株/h。

In order to understand the production effects and influencing factors of the 2JC-500 automatic grafting machine,a production test for watermelon had been done and the effects of watermelon seedling shapes on working performances were studied.The results indicate that,three situations（such as cotyledon flare angle of stock lower than 45°,curving hypocotyl of watermelon scion,and cotyledon asymmetric with hypocotyl）have significant effects on the quality of perforating stock and jointing stock with scion,respectively.When cotyledon flare angle of stock is larger than 45°,hypocotyl of watermelon scion is unbent and symmetric with hypocotyl,grafting success rate of 2JC-500 automatic grafting machine can be above 90%,and the productivity can be 450 seedlings per hour.
