1.早修剪,防伤流 葡萄修剪适宜时期为落叶后至早春树液流动前。在树液开始流动时(伤流期)修剪,剪口流汁,造成大量有机养料损失,削弱树势,影响花序发育,引起落花落果、枯枝死蔓,严重的全株死亡。因此,葡萄修剪宜早不宜迟,要在“伤流”前完成。如因修剪不及时或其他创伤引起“伤流”,必须及时用棉絮将伤口汁液擦干,涂上封蜡或用薄膜严密包扎,防止树液继续外流。 2.合理施肥,补充养料 萌芽前对树势弱的每667平方米施尿素10公斤~12公斤,树势强的少施或不施氮肥。谢花后每667平方米施复合肥40公斤,壮果期重施钾肥,采果后重施有机肥,从萌芽开始,每隔15天~20天喷施
1. Early pruning, anti-injury grape pruning suitable period of deciduous to early spring before the flow of sap flow. When the liquid begins to flow (injury stage) pruning, cutting mouth flow juice, resulting in a large number of organic nutrients loss, weaken the tree vigor, affecting the inflorescence development, causing drop flowers, dead branches dead, severe whole plant death. Therefore, grape pruning sooner rather than later, to be completed before the “bleeding”. As a result of improper pruning or other trauma caused by “bleeding” must be timely with cotton wool wound juice, coated with wax or wrapped tightly with the film to prevent sap continue to drain. 2. Reasonable fertilization, nutrient supplement Before the bud on the tree weak per 667 square meters of urea applied 10 kg to 12 kg, the strong tree less or no nitrogen fertilizer. After Thanksgiving spent 667 square meters compound fertilizer 40 kg, Zhuangguizhishi re-application of potash, picking fruit after re-application of organic fertilizer, starting from the bud, every 15 days to 20 days spraying
