在当年播种、当年嫁接、当年出圃的快速育苗中,嫁接时砧木正处于旺盛生长时期,处理砧干的方法不同,对嫁接苗的影响很大。因此采用正确的砧干处理技术是保证苗木当年出圃的主要关键之一。砧于处理对提高当年出圃苗木的嫁接成活率、萌发率和苗木的生长都有直接关系。根据1958年各地育苗工作的报告,对于砧干处理的方法、时间等问题,各持有不同意见;有的认为剪砧效果较好,有的认为折砧效果好。即使在折砧处理中,对折砧后剪除断干的时期上也有分歧意见。为了更进一步阐明和解决上述各项问题,我们结合大面积快速育苗,进行了砧干处理对嫁接苗影响的研究。
In that year sowing, then grafting, nursery out of the rapid nursery, grafting rootstock is in a period of vigorous growth, the different methods of processing anvil, grafting on the impact of a great deal. Therefore, using the correct anvil stemming technology is one of the key points to ensure that nursery stock can be exported to nursery garden. Anvil in the treatment of the nursery stock to improve the survival rate, the germination rate and the growth of seedlings are directly related. According to the reports of nursery crops in various places in 1958, there were different opinions on the methods and time of the anvil-stemming treatment. Some thought that the anvil-cutting effect was better, while others thought that the anvil-rooting effect was good. Even in the anvil treatment, there is disagreement over the period after the anvil is cut off and dried. In order to further clarify and solve the above problems, we combined with a large area of rapid nursery, the impact of grafting on the impact of anvil processing.
