近年来山葡萄栽培发展迅速,而苗木却供不应求。目前一些科研、生产和教学等单位先后开展了绿枝扦插、组织培养等育苗方面的试验研究,取得一定进展。但在生产上仍以硬枝扦插繁殖为主要的育苗方法。虽然插条生根率已达70—80％。幼苗移栽圃地成活率80—90％,成苗率可达60％以上,但当前在育苗生产中尚存在繁殖系数不高的问题。在当前种条缺少的情况下,如何提高扦插繁殖系数是加快山葡萄栽培发展极为重要的一环。根据几年来的体会,提出以下意见供参考。一、确保催根炕床质量、是提高扦插繁殖系数的主要因素目前山葡萄硬枝扦插育苗主要采用电热
In recent years, the rapid development of grape cultivation in the mountains, seedlings are in short supply. At present, some scientific research, production and teaching and other units have carried out green branch cutting, tissue culture and other nursery research and made some progress. However, the production is still hardwood cutting propagation as the main nursery method. Although the rooting rate of cuttings has reached 70-80%. Survival rate of seedling transplanted nursery 80-90%, seedling rate of up to 60% or more, but there are still breeding problems in the breeding coefficient is not high. In the current lack of species, how to improve cutting propagation coefficient is to speed up the development of viticulture is extremely important part. According to the experience of the past few years, put forward the following opinions for reference. First, to ensure that the quality of the root bed kang bed is to increase the main factor of cutting propagation coefficient At present, grapes hardwood cuttage nursery mainly electric
