Planting Technique of Plum Seedlings with Bee Sugar

Planting density: mountain, hilly or barren land can be planted according to the plant row spacing of 4 meters × 3 meters, while the plots with good soil fertility can be planted according to the plant row spacing of 3 meters × 5 meters. Fertilizer and water management: 4000kg organic fertilizer can be applied per mu in October in autumn. Branch management: control the growth of new shoots and promote flower bud differentiation. Flower and fruit management: remove deformed fruit, disease and insect fruit and surplus fruit. Prevention and control of diseases and insect pests: spray 5 degrees stone sulfur mixture to clear the garden.

I. planting density

The main results are as follows: 1. Honey plum grows fast and the tree potential is prosperous. According to the topography, soil fertility and the requirements for early yield, it is necessary to determine the planting density reasonably. In general mountain areas, hills or barren land, it is recommended to adopt the plant row spacing of 4 meters × 3 meters. Pruning according to natural happy shape, or close planting at a distance of 2 meters × 3 meters.

2. Pruning according to the trunk shape and pruning long branches to achieve the purpose of early high yield. For the land with good soil fertility, it can be sparsely planted properly. It is suggested that the plant spacing of 3 meters × 5 meters should be adopted and pruned according to the happy shape.

II. Fertilizer and water management

The main results are as follows: 1. The number of melitose plums is relatively large, and the demand for fertilizer and water is higher. It is suggested that base fertilizer should be re-applied in autumn, with 4000kg organic fertilizer per mu, while weak trees can be applied once before flowering, or potassium sulfate-type nitrogen, phosphorus and potassium compound fertilizer.

2. After the hard core period, combined with pest control every 15 days or so, foliar fertilizer such as potassium dihydrogen phosphate can be sprayed to the leaf.

3. Immediately after fruit harvest, phosphorus and potassium fertilizer is applied once to restore the tree potential, and at the same time, it is necessary to ensure adequate water supply according to the soil moisture, especially in the budding stage, the fruit hard kernel stage and the rapid expansion period.

Third, branch management

In order to control the vigorous growth of new shoots and promote flower bud differentiation, we can control the vigorous growth of new shoots and weaken the tree potential by coring, twisting slightly, smoothing branches, pulling branches, ring cutting, or using plant growth regulator paclobutrazol, etc. to achieve a balance between vegetative growth and reproductive growth and promote flower bud differentiation.

IV. Flower and fruit management

1. According to the proportion of 8:1, "April plum" with the same florescence and strong pollen affinity was allocated, and cross-pollination was used to improve the fruit setting rate, strict fruit thinning and reasonable load. when the bee sugar plum enters the full fruit stage, the fruit setting is good, and the fruit needs to be thinned strictly and loaded reasonably in order to achieve the due fruit size and good quality.

2. In general, fruit thinning can be carried out at the end of April when there is a clear distinction between large and small fruits, during which deformed fruits, disease and insect pests and excess fruits are removed, flower clusters and short fruit branches retain one fruit, and medium and long fruit branches retain one fruit at an interval of 4-5 cm.

V. Prevention and control of diseases and insect pests

Bee sugar plum is more resistant to bacterial perforation and gum disease, and its diseases and insect pests are lighter. After defoliation to before germination, it can be sprayed with 5-degree stone-sulfur mixture to clear the garden, pay attention to the control of aphids before and after flowering, and other diseases and insect pests can be used reasonably according to the occurrence.

VI. Timely harvest

It is generally appropriate to harvest in the hard ripening period, that is, the background color of the pericarp changes from green to yellow and the taste is crisp and sweet.
