摘要
根据余庆县蚕桑生产现需大量嫁接桑苗，而自育又效果欠佳的实际，笔者从桑苗的冬、春嫁接在余庆县的正确开始时间和嫁接法选优两方面着手设计试验，结果应用本县气象局气象资料及有关外地蚕桑技术资料进行分析，初步摸清桑苗嫁接必须在气温稳定提高到５℃左右条件下进行，成活率高而稳；嫁接法应以切皮芽接为主，视天气变化兼使简易芽接，袋接。
y the analysis on meteorological records of Yuqing county and
technical data of the silkworm,and mulberry from other regions, some technical target were
suggested that the mulberry sapling must be grafted under he condition as air temperature
was steadily increased to about 5℃, so that the servival ratio was high and stable。 The cut
grafting should be the main method. Ordinary bud grafting or bag grafting could be used
according to the actual weather condition.
