What solar terms are most suitable for grafting apricot trees?

Bud grafting is generally used in summer and autumn, and the grafting period is from June to September, but the rainy season in July should be avoided. Drought and high temperature in mid-June is the first suitable grafting period in North China, and early August after rainy season is the second suitable grafting period. Methods T-bud grafting and bud grafting with xylem can be used. When the rootstock reaches the grafting thickness and the rootstock and scion are peeled off, the "T" type bud grafting is adopted. This method is fast and efficient, and can sprout with xylem without peeling rootstocks and scions. If you want to cultivate the seedlings of the current year, the grafting time should be carried out before the end of June. After grafting, the rootstock can be cut off immediately to make the seedlings grow, but after grafting, the seedlings should be carefully managed to cultivate strong seedlings. Summer and autumn buds should be picked on sunny days. Grafting in sunny days is helpful to interface healing and has a high survival rate. Grafting is easy to stick in rainy season, and the interface cannot survive. For those that germinate in autumn, it is not necessary to cut the anvil that year, and then cut the anvil when it germinates in the next spring.
