What are the altitude requirements for growing Fengtang plums?
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. ⟦4 <p class="cintro"><span>Summary</span>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.</p> <p></p> <p><strong>I. Reasonable Close Planting</strong></p><p>1. Fengtang plums grow relatively fast and the trees are fairly vigorous, and they are generally planted in areas below 1200 m in altitude. The planting density can be reasonably determined according to the specific topography and landforms, soil fertility, and the requirements for early yield.</p><p>2. In mountainous areas, hills, and relatively barren areas, it is recommended to use 4 m between plants and 3 m between rows, and prune into a natural open-center shape. They can also be closely planted at 2 m between rows and 3 m between plants, pruning into a central-leader shape, so as to achieve early yield increases.</p><p>3. In areas with relatively good soil fertility, planting can be appropriately thinner, using 3 m between plants and 5 m between rows, and pruning into an open-center shape.</p><p></p><p><strong>II. Strengthen Water and Fertilizer Management</strong></p><p>1. Fengtang plum fruits are relatively large and have relatively high nutrient requirements. Generally, in autumn in October, sufficient base fertilizer needs to be applied, about 4000 kg of organic fertilizer per mu.</p><p>2. For weak trees, before flowering, one topdressing of decomposed human feces and urine or potassium sulfate type nitrogen-phosphorus compound fertilizer can be applied.</p><p>3. After the pit-hardening stage, about every half month, together with pest and disease control, foliar fertilizers such as potassium dihydrogen phosphate can be sprayed.</p><p>4. After harvest, one topdressing of phosphorus and potassium fertilizer needs to be applied in time, which helps restore tree vigor. At the same time, water according to soil moisture conditions. Especially during the bud break stage, fruit pit-hardening stage, and rapid expansion stage, sufficient water all needs to be provided.</p><p></p><p><strong>III. Flower and Fruit Management</strong></p><p>1. Improve fruit set rate: “Siyue plum” can be planted at a ratio of 8:1, with a flowering period similar to that of Fengtang plum and relatively strong pollen compatibility, and cross-pollination can be used to improve the fruit set rate.</p><p>2. Strict fruit thinning: After Fengtang plum enters the full bearing period and fruit set is good, strict fruit thinning can begin, with a reasonable load, as this is conducive to improving fruit quality and size.</p><p>3. Fruit thinning time: Generally, fruit thinning can be carried out in late April, when the distinction between large and small fruits is relatively obvious. Diseased and insect-damaged fruits, excess fruits, and deformed fruits should be removed. Flower cluster-type fruit branches and short fruit branches can retain 1 fruit, and middle and long fruit branches can retain 1 fruit every 4-5 cm.</p><p></p><p><strong>IV. Shoot Management</strong></p><p>Measures such as bending branches, pulling branches, girdling, pinching, twisting shoots, and using 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.</p><p></p><p><strong>V. Later Stage Management</strong></p><p>1. Fengtang plum is relatively resistant to gummosis and bacterial shot hole disease. The occurrence of disease is relatively mild. After leaf fall and before bud break, 5-degree lime sulfur mixture can be sprayed to clean the orchard.</p><p>2. Aphids need to be controlled before and after flowering. Other pests and diseases can be treated reasonably with pesticides according to specific conditions.</p><p>3. Harvest is generally better at the firm-ripe stage, when the base color of the fruit skin changes from green to yellow and the taste is crisp and sweet.</p>

How to plant Fengtang plum saplings? A detailed guide to growing techniques
Abstract Planting density: on mountainous, hilly or barren land, planting can be done at a row spacing of 4 m x 3 m, while on plots with better soil fertility, planting can be done at a row spacing of 3 m x 5 m. Fertilizer and water management: in October of autumn, 4000 kg of organic fertilizer can be applied per mu
