How many years of black persimmon seedlings bear fruit?

Black persimmon is a relatively rare persimmon variety with high nutritional value. It contains more vitamins and sugar than ordinary fruits. The vitamin C content is twice that of ordinary persimmon. How many years does the black tree bear fruit?

How many years do black persimmon seedlings bear fruit?

Black persimmon seedlings bear fruit about three years after planting, and the yield will increase year by year. Black persimmon seedlings are mainly planted in Guangdong, Hainan and other areas with higher temperature.

Second, the reproduction method of black persimmon trees

Grafting method is adopted, bud grafting should be carried out in the slow growth period. Young trees have two growth cycles a year, the first ending in mid-June and the second ending in mid-September. Before stopping, sap flow is the slowest, which is beneficial to grafting healing. Therefore, the suitable period for bud grafting is from late May to early June and from late August to early September. Through experience, bud grafting can be carried out during the flowering period from May to June. From phenology, bud grafting can be carried out during this period of time from the appearance of flowers on branches until the fruit has grown into walnut size.

3. Technical points of persimmon grafting survival rate

1. Selection of rootstock

Diospyros can be selected, other rootstocks should not be selected. To cultivate healthy rootstocks, measures such as intertillage, weeding, fertilization, timely prevention and control of diseases and insect pests, and topping after seedling height of 30 cm should be implemented.

2. timely grafting

Branching: select the ungerminated fruiting mother branches of the previous year to prevent scions from drying out. Grafting should be carried out when rootstock sap begins to flow and scion is in the initial germination state, generally from the middle to the last ten days of February. Grafting too early, the stock and ear are still dormant, the interface cells will dry up, so that the interface dead cell layer will thicken, affecting the survival of grafting. Too late, scion has sprouted, grafted easy to dry water.

Bud grafting: scion should be selected in the middle of the year healthy young shoots full bud, with the pick with the next, to put the scion into clean water, in case the tannin on the incision is oxidized, scion can not be stored for a long time. Grafting is suitable when scion tissue is full, rootstock sap flow slows down and peeling is easy. The survival rate is highest in late August to early September. Environmental requirements for grafting. Choose cloudy, windless, humid weather grafting, but do not carry out in rainy days, let alone let rain directly into the interface.

Black persimmon in addition to high nutritional value, its wood is gray black, hard and heavy, fine structure, quite resistant to decay, can be used for construction, machinery and furniture and other materials.
