葡萄多次结果技术在二十几年前已在生产上应用。1957年以来,在国内的一些生产单位和研究机构作了进一步的研究。由于技术操作比较繁琐,需要劳动力较多,因而不便于在较大的面积上应用。本报导通过主梢和付梢摘心或去除强度与时期的观察,以及利用P~(32)示踪方法测定付梢摘心与不摘心,P~(32)在结果枝内运转动态,指出对冬芽花芽分化的影响。初步提出了利用冬芽结二次果较简化的技术措施,并对试验结果进行了讨论。
Grapes multiple result technology in the twenty years ago has been applied in production. Since 1957, some domestic production units and research institutes have made further research. As the technical operation is more cumbersome, requiring more labor, which is not easy to use in a larger area. This paper reports the observation of pinching or removal of intensity and period through the main shoot and the removal of the top and bottom of the shoot and the use of the P ~ (32) Effect of flower bud differentiation. Preliminary proposed the use of winter buds secondary fruit more simple technical measures, and the test results were discussed.
