The period of grafting of rootstocks

There are four suitable periods for grafting of jujube seedlings in nursery: 2 to 3 weeks before ⑴ spring germination, the temperature is about 10 degrees, which is a good time for cutting and tongue grafting, and 3 to 4 weeks after ⑵ germination. When the temperature is about 15 degrees, the phloem is easy to peel off, which is the suitable time for subcutaneous grafting, and the high temperature season of ⑶ from July to August in summer. It is the best time for subcutaneous grafting, and the survival rate is high, which can sprout and sprout in the next 10 days, and ⑷ from late August to late September. The branches have stopped growing and are suitable for tongue grafting. When grafting, cut the rootstock 30 cm from the ground, leaving some auxiliary branches. It is not easy to be grafted after rain or rainy season, and the grafting wound is prone to bleeding, which leads to grafting failure.
