Cutting,Grafting buds, flowers and fruits of persimmon 

If persimmons leave their fruit unchecked, it is easy to cause the next year's fruit, the fruit becomes smaller, and the commodity value is low. Therefore, proper bud thinning, flower thinning and fruit thinning should be implemented. Generally, the fruit in the middle part of the branch is larger, the ripening period is early, the coloring is good, and the sugar content is also high. Therefore, when thinning buds and flowers, all the tips of the fruiting branches and late flowers need to be thinned out, and 1 juxtaposed flower bud is removed, leaving only 1 to 2 flower buds from the base to the middle of the fruiting branch, and the rest are omitted. The blooming period is when the buds can be twisted by the fingers. Fruit thinning can be carried out at the end of physiological fruit drop, and all the fruits that are poorly developed, injured sepals, deformed fruits, diseases and insect pests, and fruits that are susceptible to sunburn and upward growth are eliminated. The degree of fruit thinning must be matched with the number of leaves on the branches, and the ratio of leaf to fruit is generally controlled at 15 leaves to 1 fruit.

Plastic trimming

1. The saplings should be pruned lightly. The winter shears should be short cut, supplemented by thinning. The purpose is to increase branches, promote transformation, and lay a good foundation for early yield.

2. The pruning of fruit trees in winter is mainly thinning, the main branch extension head is shortened to expand the crown, summer is mainly used to lure branches, long branches are pinched, for rich varieties, the mother branch cannot be short, and the main branch is more sparse. , 3-4 year-old fruiting mother branches need to be thinned and renewed to promote thick fruiting mother branches. The Dansiwan varieties adopt the pruning technique of leaving short branches and low crown, and the rest are conventional pruning.

3. Pruning and shrinking large branches of senescent trees can promote the emergence of new branches. The degree of shrinkage can be left in the 5-7-year-old part, and the extraordinarily long branches can be pinched, and other pruning measures can be used to restore the fruiting ability.

Persimmon trees are generally trimmed and pruned according to their natural open shape. The structure of the tree body is 30-60 cm in height. Three main branches are suitable. The distance between the first main branch and the second main branch is about 30 cm. The distance between the main branch and the third main branch is more than 20 cm. In the growth period of fruit trees, the main tasks are to remove sprouts, twist tips and topple. Excluding sprouting means that when most fruiting branches occur from the fruiting mother branch, 2 fruiting branches from the middle are left, and the others are removed early. For the elongated branches that must be kept in the proper position, when they grow to about 30 cm and the base is not hardened, the base is twisted to suppress its elongated growth, and the core is stopped .

4. How to use persimmon seeds to grow persimmons in flower pots?

1. Planting time Persimmon trees are deciduous fruit trees. They are required to be planted after deciduous leaves before budding. The most suitable period is after the fall of leaves in autumn and before all things germinate in spring. Pay attention to the spacing when planting, not too dense, to prevent affecting the flowering and fruiting period.

2 Second, the best time for pruning the branches After the main leaves fall, cut dry and excessively branched, and the nodes with fewer nodes can be cut off appropriately. In its environment, trim its suitable tree type.

3. Water and Fertilizer Management The moisture content of the soil for planting persimmon trees is best maintained at about 35%. This moisture content can allow the persimmon trees to achieve the best growth state. The fertilizer needed for persimmon is mainly nitrogen fertilizer, followed by potassium fertilizer and phosphate fertilizer.

4. Gardening work. Winter cleaning is to prepare in advance for the next year's flowering and fruiting. Pruning should thoroughly remove diseased fruits, diseased stalks, dead branches and fallen leaves, and remove the source of overwintering diseases and insects. There are many pests that rely on trees to survive the winter, so pay attention to cleaning them up.

Most varieties of persimmon trees begin to bear fruit 34 years after grafting, reaching the full fruit period in the year, and the seedling trees begin to bear fruit at 57 years old, and the fruiting life is more than 100 years.

It was originally produced in the Yangtze River Basin of China, Japan and Pakistan also known as Japanese pal.

5. Persimmon planting technology

One urea solution or potassium dihydrogen phosphate solution once; after the height of the seedlings is 20 cm, kilograms of human excrement and urine per mu shall be applied every 15 days. Thinning in May, leaving seedlings per square meter. Topping when the seedling is 40 cm high. 4. Grasp the opportunity and make a surprise graft. Assault grafting in early July. Choose the excellent plant that enters the full-fruit stage as the mother tree for harvesting ears, and cut the shoots of the previous year's autumn shoots or the strong buds in the middle of the spring shoots of the year for budding. The bud pieces are cut into 3 cm long, slightly with xylem. Place the rootstock 710 cm above the ground, and cut into a cut with the same size as the cut surface of the bud slice, deep to the cambium, without damaging the xylem. Stick the bud piece on the cut surface of the rootstock, tie the interface with the exposed bud with plastic film, and break the rootstock 10 cm above the joint. Twenty days after the connection, the band was lifted and the rootstock above the connection position was cut off. Promote first and then control, cultivate strong seedlings.  Apply more fertilizers before late September, cool down the irrigation water, wipe off the root buds, and promote the growth of the grafts; reapply phosphorus and potassium fertilizers in late September, and then stop fertilizing and irrigation. When the seedling is 60 cm high, it can be pinched to promote the thick growth and lignification of grafted seedlings. Generally, the seedlings can be planted out of the nursery when the diameter of the base of the seedlings reaches 0.8 cm. Agricultural Technology Extension.
