巨峰葡萄为四倍体品种,果粒大,味甜汁多,黑紫色,有草莓香味,品质优良。1975年由北京引到十堰市郊种植。近几年,我们观察发现其下位弱枝座果比上位壮枝好,两次果座果率比一次果高,脱落果粒无籽等现象。这给我们一个启示,一次果落花落果的主要原因可能是新梢旺长所致。为此,1980年,我们以控梢促果为主,结合其他技术措施进行丰产栽培试验,试求探明巨峰葡萄落花落果的原因,提出相应的技术措施,总结稳产高产的途径。 Kyoho grapes for tetraploid varieties, large fruit, sweet juicy, dark purple, strawberry flavor, high quality. In 1975 introduced by Beijing to Shiyan suburbs planting. In recent years, we observed that the lower position of weak branches better than the superior Zhuang Zhi good, twice the fruit rate of fruit than once, off the fruit seeds and other phenomena. This gives us a revelation, one of the main reasons for falling fruit may be caused by the proliferation of new shoots. To this end, in 1980, we focus on the control of fruit and fruit, combined with other technical measures for high yield cultivation test, trying to find out the reasons for falling fruit of Kyoho grape, the corresponding technical measures to sum up the ways of high and stable yield.
