七、疏花疏果与果实套袋 1.疏花疏果 为了调整植株负载量,适当控制产量,提高果实品质,克服结果大小年现象,确保优质、丰收、稳产,必须疏花疏果。①整修花序。在开花前1周进行,二三天内完成。若时间太早,穗形难以辨认;时间太晚,则影响效果。对大花穗,先除去副穗,然后在花穗主轴基部除去1个～8个支轴;对小花穗,少去或不去。如果主轴基部 7, thinning and fruit thinning bagging 1. Thinning fruit thinning In order to adjust the plant load, the appropriate control of yield, improve fruit quality, to overcome the size of the results of the year to ensure high quality, good harvest, stable yield, must thinning thinning. ① renovation inflorescence. 1 week before flowering, two or three days to complete. If the time is too early, the spike shape is illegible; the time is too late, then the effect.
