How to grow crispy persimmons

Crispy persimmons, as the name implies, are crispy persimmons. Although they are crisp, the fruit is also ripe, different from soft persimmons, so how to grow crispy persimmons?

I. Seedling selection

The seedlings with no diseases and insect pests and good plant quality were selected for cultivation.

It is better for one-year-old strong seedlings with straight seedlings, good interface healing, intact root system, seedling height ≥ 70cm, diameter ≥ 0.8cm at 3 cm above the interface, and more than 5 full buds in the plastic belt.

2. Planting

Plant and fertilize according to the appropriate density, followed by watering and film mulching.

1. Configuration: the self-flowering seed setting rate of sweet and crisp persimmon is low, so pollination varieties should be allocated, the appropriate ratio is 10 ∶ 1, and the planting time is from late November to the end of February of the following year.

2. Density: the row spacing of conventional cultivation plants is 4 m × 4 m, the row spacing of 500 × 630 plants per hectare (42 plants / mu ~ 33 plants / mu), the row spacing of densely planted plants is 2 × 3 m × 3 m / mu, and it is suitable to plant 830 plants per hectare (550.111 plants / mu).

3. Fertilization: the depth of reclamation in the whole garden is 40-50 cm, and the stones, tree roots and firewood roots are removed, set out at a fixed point according to the set distance between the plants, and then dig a planting hole 60-80 cm deep and 80-100 cm square. Fertilize after returning to the soil half-hole in the planting hole, apply 50 kg mature barnyard manure or compost in each hole, add 1 kg calcium magnesium phosphate or calcium superphosphate fertilizer or superphosphate, fully mix the fertilizer and soil, and then return to the soil to the appropriate height to be planted.

4. Planting: put the seedlings into the planting hole, stretch the roots, and lift the seedlings up and down slightly while filling the soil. The filling height should be that the root neck of the seedlings is about 5 cm above the ground, and a ridge should be built around.

5. Watering: water permeable or thin dung immediately after planting.

6. Film mulching: cover 1-1.5 square meters of plastic film after watering.

III. Field management

1. Soil

Dig deep. The whole garden is turned deeply every 2-3 years, with a depth of about 30-40 cm, gradually deepening outward from the trunk.

2. Watering

Avoid stagnant water, should open 30-40 cm deep drainage ditch in the garden, rainy season or after heavy rain, should eliminate stagnant water as soon as possible, dry season should be timely irrigation, drip irrigation, sprinkler irrigation, furrow irrigation or irrigation, and can be covered with grass or plastic film around the tree plate to preserve moisture.

4. Pruning

The young trees cut short the trunk and main side branches, long and release the fruiting mother branches, and thinning and deleting disease and insect branches, over-dense branches, competitive branches, overlapping branches and cross branches. The adult trees cut short the backbone branches and lateral branches which are too weak and slender, delete the disease and insect branches, over-dense branches, competitive branches, overlapping branches and cross branches, and retract and renew the weak old branches after fruiting.

Timely erase the buds on the back and dense buds in the early stage of germination. In the early stage of growth, the growing point of the shoot with higher growth position and stronger growth potential was removed in time, and the strong upright branch was pulled or twisted as needed to make it a mother branch with good results.
