Rapid Seedling Technology of Japanese Persimmon

Japanese sweet persimmon is a kind of sweet persimmon, the fruit matures on the tree and can be easily removed from the astringent. Japanese sweet persimmons have greater advantages than other varieties, and can be easily removed from the astringent, eliminating the need for post-harvest astringent work. It can be quickly brought to market after harvest, and the appearance and quality of the fruit are good. It is particularly suitable for cultivation in hills and mountains. It grows rough and grows quickly. It is an excellent fruit tree variety for farmers in mountainous areas to become rich. Persimmon breeding is commonly used in winter dormancy grafting, the author passed the test, summer and autumn can be grafted, the survival rate of up to 90%, grafted then winter can be out of the garden. The key techniques for its rapid seedling cultivation are as follows: 1. Selection of Rootstocks The matching of Japanese sweet persimmons to rootstocks is more stringent. In the past, the survival rate of grafting with oil persimmons as rootstocks was low. Grafted seedlings showed incompatibility at the grafted sites, ie, the joints of the scion and rootstock were inflated to form large trunks. After screening, the author chose Junqianzi as the rootstock to perform well, the survival rate is high, and the combination of the rootstocks and panicles is intact and incompatibility does not occur. Second, the grafting time In order to achieve the goal of grafting the nursery in the same year, it can be adopted in summer or autumn. Seeds of seedlings were sown in February. Seedlings were carefully treated with fertilizer and water, and trunks were grafted at 0.5 cm or more. Grafting time from July to September, as long as the scion branches are old and can be grafted. The summer connection can be pulled out for a second time, and the autumn connection can be taken for a second time. Third, grafting method selection of a good mother tree, shoot bud full of robust and disease-free shoots for scion. The rootstock was cut about 15 cm from the ground, and a knife was cut perpendicularly between the xylem and the forming layer. The length was 1.5 to 2 cm, and a short slope of 30 was cut on the opposite side. The cutting method of the scion is to cut approximately 2 cm or 2 cm in length, cut a joint similar to the rootstock in a smooth place, and cut a slope of 30 in the opposite side. The scion is aligned with the rootstock forming layer, and the ultra-thin film is bandaged from bottom to top so that the seal is airtight, and after 20 days, the shoot can be broken.
