柑桔夏秋嫁接,次年初春剪砧,促抽壮梢,是柑桔苗木繁殖工作中多年来的生产措施。但欲早夏嫁接,当年促抽壮梢出圃,应采取何种措施,是值得研究的。柑桔苗木生产者常在这方面想了不少办法,但多不够理想。我们在良种繁殖工作中,曾多次采用老办法,在芽接成活后及时剪砧,希当年抽发壮梢,当年出圃,但结果抽梢短小,达不到出圃标准。我们曾学习广东倒砧促芽法,希能抽出壮梢,结果仍不能达到标准。而且因倒 Grafting citrus summer and autumn, the following year early spring shear anvil, promote pumping strong shoots, citrus seedling breeding work over the years of production measures. However, if we want to grafting as early as the summer, what measures should be taken to promote the construction of the nursery should be studied. Citrus seedlings producers often think of many ways in this regard, but many are not ideal. We have used the old method many times during the propagation of seed breeding. We cut the rootstock in time after the budding process. In the same year, we drew the strong shoots and went out of cultivation in the same year. However, the result was too short to reach the standard of cultivation. We have learned Guangdong anvil to promote bud law, hope to pull out strong, the results still can not meet the standards. And because of down
