Nuclear seed of persimmon?

Persimmon kernels can be planted, but people generally do not sow persimmon kernels because the quality of persimmons produced by seedlings is not good. The most commonly used method is grafting planting. The planting steps of persimmon are seedling propagation, then planting in winter, soil management in the growth process, and fruit drop control.

Nuclear seed of persimmon?

Persimmon kernels can be planted directly, but the quality is not good, so it is not recommended to use persimmon kernels directly. We generally adopt the method of grafting to plant persimmons. The rootstock uses Jun Qianzi, which generally has more than 10 seeds. In winter, when the sand is mixed with sand, the humidity of the sand is adjusted to shape by hand, but there is no water flow between the fingers. It is appropriate to put it in a place of about 5 degrees. Sow in spring, and then grafting in time.

Planting technique of persimmon

First, seedling reproduction

1. Rootstock: the rootstock is cultivated by planting persimmon, and the sowing time is suitable for December of each year and January of the following year.

2. Seedling breeding: the seedlings were propagated by grafting and cut before the rootstock and scion began to move in winter.

II. Colonization

The planting period of persimmon is generally from December to February, when the mature organic matter is mixed in the hole, the suitable distance between rows and plants is from 7 m × 7 m to 12 m × 12 m, with about 200 plants per hectare.

III. Soil management

1. Soil sampling and analysis

The soil should be sampled and analyzed every year, and the topsoil and subsoil of the park should be evenly mixed for soil analysis. according to the analysis results, soil improvement and fertilization treatment should be carried out in time.

2. Soil improvement.

Persimmon is suitable for growing in alkaline soil. When the soil PH value is too low, it should be improved by using bitter soil lime mixed with limestone powder in time, and the annual application amount should not exceed 4000 jin per hectare. It should be applied in stages after fruit picking or during dormancy. It is responsible for the absorption of trace elements due to changes in acidity and alkalinity.

3. Application of organic matter

In order for persimmon to grow healthily, it is necessary to increase the content of soil organic matter in time, and generally apply mature organic matter with high ratio of carbon to nitrogen, so as to improve soil condition and reduce the occurrence of root rot.

4. Grass cultivation

Persimmon trees are not resistant to drought. In order to make persimmon trees grow well, grass cultivation should be carried out in the orchard and the cut hay should be covered under the tree crown to prevent soil erosion and increase soil protection and drainage capacity.

IV. Prevention and control of fruit drop

1. Provide pollination source

The female flowers of Niuxin persimmon and stone persimmon are mostly, and grafting pollination can prevent fruit falling. Niuxin persimmon is round and large after pollination, but the disadvantage is that Niuxin persimmon has a nucleus after pollination, which has a slight effect on persimmon production.

2. Circular peeling

Persimmon tree is about to bloom when the trunk or main branch ring peeling, can improve the fruit drop, but this method will affect the later root growth, fruit quality will become worse, so try to avoid use.

3. Strengthen cultivation and management.

Avoid cutting branches as much as possible, control the use of nitrogen fertilizer and the adjustment of moisture, and thinning flowers and buds in time when the buds bloom for a long time, all of which are good for the fall of fruits.
