Summary: Fengtang plums need to be grown in areas below 1200 m in altitude. Reasonable close planting should be carried out according to the topography and landforms. In mountainous areas, hills, and relatively barren areas, it is recommended to plant at a density of 3-4 m between plants and 2-3 m between rows, while in plots with better soil and fertilizer, planting can be appropriately thinner.

AbstractHoney plum (Fengtang plum) needs to be planted in areas below 1200 m in altitude, and should be reasonably densely planted according to the terrain and landforms. In mountainous areas, hills and relatively barren areas, it is recommended to plant at a density with a plant spacing of 3-4 m and a row spacing of 2-3 m, while in plots with better soil and fertilizer, it can be appropriately planted more sparsely.
I. Reasonable dense planting
1. Honey plum grows relatively fast and the tree vigor is rather vigorous, and it is generally planted in areas below 1200 m in altitude. The planting density can be reasonably determined according to the specific terrain and landforms, soil fertility and the requirements for early yield.
2. In mountainous areas, hills and relatively barren areas, it is recommended to use a plant spacing of 4 m and a row spacing of 3 m, and to prune into a natural open-center shape; it can also be densely planted at a row spacing of 2 m and a plant spacing of 3 m, and pruned into a central-leader shape, so as to achieve early yield increase.
3. In areas with relatively good soil fertility, it can be appropriately planted more sparsely, using a plant spacing of 3 m and a row spacing of 5 m, and pruned into an open-center shape.
II. Strengthen water and fertilizer management
1. Honey plum fruit is relatively large and has relatively high nutrient requirements. Generally, in autumn in October, sufficient base fertilizer needs to be applied, about 4000 kg of organic fertilizer per mu.
2. For weak trees, one topdressing of decomposed human manure or potassium sulfate type nitrogen-phosphorus compound fertilizer can be applied before flowering.
3. After the pit-hardening stage, about every half a month, foliar fertilizers such as potassium dihydrogen phosphate can be sprayed together with pest and disease control.
4. After harvest, a topdressing of phosphorus and potassium fertilizer needs to be applied in time, which is conducive to restoring tree vigor. At the same time, watering should be carried out according to soil moisture conditions, especially during the bud burst stage, fruit pit-hardening stage and rapid expansion stage, all of which require sufficient water supply.
III. Flower and fruit management
1. Improve fruit set rate: “April plum”, whose flowering period is similar to that of honey plum and whose pollen has strong compatibility, can be planted at a ratio of 8:1, and cross-pollination can be used to improve the fruit set rate.
2. Strict fruit thinning: After honey plum enters the full fruit stage and fruit set is good, strict fruit thinning can begin with a reasonable load, which is conducive to improving fruit quality and size.
3. Fruit thinning time: Generally, fruit thinning can be carried out in late April, when the difference between large and small fruits is relatively obvious. Diseased and insect-damaged fruits, excess fruits and deformed fruits should be removed. One fruit can be kept on flower cluster fruit branches and short fruit branches, and one fruit can be kept every 4-5 cm on medium and long fruit branches.
IV. Shoot management
Measures such as branch bending by hand, branch pulling, girdling, pinching, shoot twisting, and the use of plant growth regulators such as paclobutrazol can effectively weaken tree vigor, prevent excessive growth of new shoots, balance vegetative and reproductive growth, and thereby promote flower bud differentiation.
V. Later stage management
1. Honey plum is relatively resistant to gummosis and bacterial shot hole disease. The occurrence of disease is relatively mild. After leaf fall and before germination, 5-degree lime sulfur mixture can be sprayed to clean the orchard.
2. Aphids need to be controlled before and after flowering, and other pests and diseases can be treated with reasonable pesticides according to specific conditions.
3. It is generally better to harvest at the firm-ripe stage, when the background color of the fruit peel changes from green to yellow and the taste is crisp and sweet.
