扦插法是我国劳动人民在林业生产上的重大贡献之一,目前已被国内外林业上广泛应用,特别在种子缺乏和良种繁殖上更具特殊意义。 要使嫩枝扦插发根早、不死苗、生长快、成壮苗,这不仅是与母树生物学特性有关,也与采用的农业技术措施有着密切的关系。 我们根据生产、教学、科研三结合的原则,组织工人、学员,教师三结合小组,对池杉踵状扦插进行了试验。现将初步结果简介如下: Cutting law is one of the major contributions made by our working people in forestry production. At present, it has been widely used in forestry both at home and abroad, especially for the lack of seeds and breeding of improved varieties. It is not only related to the biological characteristics of the mother tree, but also closely related to the agricultural techniques adopted to make the shoots of young shoots grow early, die without growth, grow fast and grow into strong seedlings. According to the principle of combining production, teaching and research, we organized the three-teaming of workers, trainees and teachers to test the heel-like cuttings of Iii. Now the preliminary results are as follows:
