一、什么是采前摘叶 采前摘叶就是在采收前一段时间把树冠中那些遮挡果面,影响果实着色的叶片摘除,以增加果面光照,避免果面局部绿斑,促进果实均匀着色的一种技术措施。 叶片是有机营养形成和果实生长发育的基础,果个增大,产量形成都离不开叶片,但在果实着色期间,当叶片密度过大,距离果面近,甚至贴在果面时,必然遮挡果面光照,形成果面绿斑。特别是近几年推广栽培的短枝型品种,短果枝枝量大,贴果叶片多,更需采前
First, what is picking leaves before picking Yee Yee Yee before harvest is in the canopy for some time to cover those who obstruct the fruit surface, affect the fruit color of the leaves removed to increase the fruit surface light, to avoid the fruit surface green spots and promote uniform fruit Coloring a technical measure. Leaves are the basis for the formation of organic nutrition and fruit growth and development, the fruit increases, the formation of the yield are inseparable from the leaves, but during the fruit coloring, when the leaf density is too large, close to the fruit surface, or even stuck in the fruit surface, inevitably Cover the fruit surface light, forming a green spot fruit. In particular, in recent years to promote the cultivation of spur-type varieties, short branches, large amount of fruit, fruit leaves more, more need to extract
