为了春天嫁接,采集和贮藏接穗日期有很重要的意义,但生产实践中很难保证能合理的贮藏接穗,致使嫁接成活率常常降低.因此1966年研究了在春、夏、秋三个季节用木质化和未木质化的接穗嫁接时,欧洲赤松的成活率、保存率和嫁接株生长的问题.试验地面积共五亩,砧木是1963年按0.6×2米株行距栽的,嫁接时为四年生,平均高67厘米,径2.8厘米.嫁接从1966年4月15日开始,直到11月26日止,六月以前间隔期为10
In order to grafting spring, it is very important to collect and store the date of scion, but it is difficult to guarantee the reasonable storage of scion in the practice of production, so the grafting survival rate is often reduced.Therefore, in 1966, Lignification and non-lignified scion grafting, the survival rate of Pinus densiflora, the preservation rate and the growth of grafted plants.Tested area of a total of five acres, the rootstock in 1963 by 0.6 × 2 meters spacing plant planted grafted Four-year-old with an average height of 67 cm and a diameter of 2.8 cm Grafting began on April 15, 1966, until November 26, and was spaced 10
