Cultivation techniques of Red Heart Plum

Red plum is a very delicious fruit with a moderate sour and sweet taste. Its flesh is bright red and the near core part is fuchsia. Zhuji and Dongyang, which mainly produce Zhejiang, are one of the main plum varieties in southern China. So, what are the cultivation techniques of red plums?

I. Garden site selection

The construction garden of neutral to slightly acidic sandy soil with sufficient light, deep soil, loose soil, adequate water source and smooth drainage should be selected. The terrain chooses terrace or gentle slope, and steamed bread mountain is the best.

Second, planting time

It can be planted from defoliation to pre-germination, and fruit growers in the south have the experience of first sprouting in autumn and first sprouting in spring. Because the plum tree has fallen leaves in autumn, but the ground temperature is high, the roots can heal and grow in the same year after planting, which is beneficial to sprout and grow in time the following year.

3. Planting density

The distance between plants and rows is 2.5 meters and 4 meters, respectively, and the planting distance is about 70 plants per mu.

IV. Planting methods

The planting hole is 1 meter wide and 0.8 meters deep. After the planting hole is dug, the soil in the hole is scoured out, and the mature soil is filled (that is, a layer of soil, a layer of straw and miscellaneous fertilizer, 10 kg of weeds and 1 kg of phosphate fertilizer are mixed into miscellaneous fertilizer), and then the original soil is backfilled to the ground, and the qualified grafted seedlings are placed in the center of the hole to make the roots stretch, base on the fine soil, tighten with the feet, form a nest plate, and irrigate the root water.

5. Pruning techniques

When the trunk grows to 50 to 60 centimeters, the tree buds with a height of less than 30 centimeters can be wiped off. When it germinates new shoots of about two centimeters, choose 4 to 5 shoots with a larger angle and stronger growth as the main branches. to facilitate their robust cultivation.

VI. Fertilizer and water management

Before planting, we must deeply turn over and improve the soil to ensure enough base fertilizer and expand holes in the coming year, which is also conducive to the growth of its new roots and proper intercropping, but avoid planting high-stem crops. The method of growing grass combined with clear ploughing can be used to let it produce naturally and prevent the loss of water. In the critical period when it needs water and fertilizer, get rid of the surrounding weeds, so that the contradiction between them can be solved, and they can also conserve water and fertilizer. Provide them with appropriate nutrients.

VII. Disease and pest control

The emphasis is on prevention, egg elimination is carried out in winter, vegetable mixture is applied on the basal trunk of crispy red plum, and sprayed on and around the trunk of crispy red plum in spring with 500-800-fold solution of enemy powder or 500-fold solution of zinc-sulfur scale to prevent pests from entering the trunk.

Finally, it should be noted that the fruit powder should be retained as much as possible during harvest, so that the fruit can be stored for longer.
