Cherry dwarf dense planting technology

1, ridiculite

The soil is ploughed and a large amount of river sand is sprinkled in the soil. Afterwards, the ridge is used to form a ridge soil heap. The function of the ridge soil is for the subsequent solidification of the fertilizer and the sand is poured into the river to reduce the disease.

2. Select rootstock seeds

The mountain cherry is used as a mother tree for picking, and the fruit is harvested when the cherry fruit is fully matured. Immediately after picking the fruit, the fruit is put into warm water to wash, the pulp is removed and the seeds are dried, and the dried seeds are mixed with the sand. Laminated and stored in the environment of 0°C -15°C. Washing with warm water is not only convenient for cleaning, but also can reduce the dormancy time of seeds. In practice, the water temperature during warm water washing is 25°C -45°C.

3. Transplanting: When the seeds in step 2 expose the white buds, they will be transplanted on the ridge soil heap described in step 1;

4. Management of seedlings: After the seeding is completed in step 3, the crushed dregs are laid on the ridge soil heap until seed grows into seedlings;

5. Grafting: Grafting when the seedling thickness is greater than 1.5 cm;

6. The ridges and soils are piled and ditched: a trapezoidal ditch with a depth of 30-45 cm is excavated on the ridge and soil pile;

7, shaping: the plant into a "Y"-shaped tree; the plant ventilation and light transmission is very good, easy to flower results, suitable for close plant management and convenient and good fruit quality;

8, young fruit tree pruning; young fruit tree pruning, the young fruit trunk height of 1m-2m;

9, Baohua Baoguo: including fertilizer and water management, pollination, spraying plant hormones; spray flowers and fruits in the spraying of plant hormones including gibberellin, green Fenwei foliar fertilizer, PP333, etc.; pollination can be artificially assisted pollination or Use insects to pollinate flowers;

10, the results of tree pruning: often pruned in the summer after fruit picking, cut too dense too strong, disturbing the perennial branches of the canopy, the crown structure adjustment, promote flower bud formation, pay attention to the wound should be small and flat, which will help healing as soon as possible; 3 When the seeds are transplanted, the positioning mark film is laid on the pile of ridge and the hole is punched on the positioning mark on the positioning mark film, and the distance between the adjacent positioning points on the positioning mark film is 45cm-80cm. When planting, it not only improves the work efficiency, but also greatly increases the yield of the plants.

The above methods are actually a kind of cherry dwarf dense planting technology with large planting area, high land utilization, and high yield. It should be noted that although China currently has the introduction of cherry fruit trees, it has not yet formed a scale; the cherry is a warm and cold-tolerant fruit tree with weak cold resistance, and flower buds are prone to frost damage and should not be planted in cold regions. Impatient and not resistant to wind, the existing technology of cherry cultivation has the disadvantages of small planting area per unit area, low land utilization, and low yield. Therefore, the cherry cultivation technology is still difficult for many farmers.
