中国农科院特产研究所经过二十多年的研究,培育出了“左山一”、“74001”等一批山葡萄丰产品系,并研究出一套适应山葡萄生长发育特性的高产栽培技术: 1.固定主蔓龙干形正枝,短梢修剪,不下架、不防寒,尽量控制避免结果部位前移、基部裸露现象发生。 2.合理密留,增加芽眼负载量,以每平方米35个为宜,结果枝数不少于30个,果穗数不少于50个。
After more than 20 years of research, the Institute of Specialty Products of Chinese Academy of Agricultural Sciences has cultivated a number of highland grape variety products such as “Zusanli” and “74001”, and has developed a set of high-yielding cultivation techniques that adapt to the growth and development characteristics of the mountain grape: 1. Main Mandragan stem is dry-shaped, short shoot pruning, no shelf, not cold, as far as possible to avoid the results of the control part of the forward, the base of the bare phenomenon. Reasonable confidentiality, increase the bud eye load, to 35 per square meter is appropriate, the result of not less than 30 branches, the number of spikes not less than 50.
