一、疏穗和定穗葡萄每一株树上应留多少果穗有严格规定,决不能见穗就留。疏穗和控穗应分两步进行,第一次现穗后,将枝蔓上萌条过密的部分抹去即可。第二次在谢花后定穗.强壮枝留1-2个穗,中庸枝留1穗,弱枝不留穗。每亩每株应留多少穗,应根据果穗大小和栽培架式而定。如特大穗品种里查马特,单穗保持1000克左右,每亩应保留2000穗,棚架每株留20穗、篱架每株留12穗。大穗品种巨峰及木纳格等,每亩可留2500-3000穗,棚架每株留25-30穗,篱架每株留18-20穗。二、抖穗谢花后,将
First, the sparse spike and fixed spike Grape of each tree should be kept on how many ears have strict rules, never see the spike to stay. Sparse spike and control spike should be carried out in two steps, the first is after the spike, the sprigs of the sprouting on the dense part can be erased. The second time after Xiehua set ears strong branch stay 1-2 spikes, moderate branch stay a spike, weak branches do not stay spike. How much spike should be left per acre should be based on the size of the ear and the cultivation rack. Such as extra large spike variety Chamat, a single spike to maintain about 1000 grams per acre should be retained 2000 spike, scaffolding leaving 20 spike per plant leaving 12 spike per panicle. Large spike varieties such as Kyoho and Minag rattan, leaving 2500-3000 spike per acre, scaffolding stay 25-30 per plant spike, fence stand 18-20 spike per plant. Second, shaking thanks after flower, will
