letter-spacing: 0.544px; text-align: justify; white-space: normal; line-height: 1.75em; word-wrap: break-word !important;">摘叶、疏果、环剥是改变源、库关子常用的手段,这三类操作对果实糖积累有重要的影响。另外适度的水分、合适的温度、适量的光照强度都会提高果实的含糖量。</h3><h3><strong style="max-width: 100%;

letter-spacing: 0.544px; text-align: justify; white-space: normal; line-height: 1.75em; word-wrap: break-word !important;">幼果期后,氮肥的供应就要控制了,适量施用氮肥对果实的糖积累有一定的促进作用,过量施用氮肥,就会降低果实的含糖量;也有相关实验研究证明,增甜效果最好的是磷肥,而钾肥排第二。</h3><p style="max-width: 100%;

letter-spacing: 0.544px; text-align: justify; white-space: normal; line-height: 1.75em; word-wrap: break-word !important;">1、适时摘掉果穗附近的老叶,可以让果粒有很多的光照时间,可加快浆果的成熟;另外,对葡萄主干主干或主蔓适时环剥,切断了上部叶片光合产物向地下根系输送的通道,使碳水化合物贮积在地上部,可促进果实中糖分的积累。</h3><p style="max-width: 100%;

letter-spacing: 0.544px; text-align: justify; white-space: normal; line-height: 1.75em; word-wrap: break-word !important;">葡萄果粉主要成分是碳水化合物,为光合作用的产物,也就是说,果实碳水化合物含量越高,果粉就越好。</h3><p style="max-width: 100%;

letter-spacing: 0.544px; text-align: justify; white-space: normal; line-height: 1.75em; word-wrap: break-word !important;">1、多使用碳氮比高的肥料,如完全腐熟或工业化生产的有机肥、水溶肥,减少使用偏酸性的复合肥,有利于果粉和糖度的提高。</h3><p style="max-width: 100%;

text-align: justify; white-space: normal; line-height: 1.75em; word-wrap: break-word !important;">3、用药时应以高质量水剂、悬浮剂或水分散粒剂的杀虫杀菌剂为主,避免使用乳油和劣质粉剂,影响果粉的形成和覆盖的均匀性。</h3> <h3>圃朗特(中国)化工有限公司
