What are the cultivation points of red pomelo?

Red-meat pomelo is a very popular fruit in recent years, and many farmers are planting it. So what are the cultivation points of red pomelo? The following small series of soil flow nets will come to share with you.

1, planting method

The planting density varies according to the terrain. The row spacing of mountain plants is 3×3.5 meters, and 55 plants are planted per mu. Plant spacing on flat ground is 3.5×4 meters, and 50 plants are planted per mu.

2. Reasonable fertilization

Young trees were mainly treated with nitrogen fertilizer, combined with phosphorus and potassium fertilizer. The principle of fertilization is to apply thin fertilizer frequently, apply shoot promotion fertilizer before each shoot, and apply strong shoot fertilizer after shooting. Adult trees are fertilized 3 - 4 times a year. Fruit picking fertilizer (winter fertilizer) is applied within 7~10 days before and after fruit picking, accounting for 40%~-60% of the annual fertilizer application amount; germination fertilizer (spring fertilizer) is applied around the end of January, accounting for 15%~25% of the annual fertilizer application amount; fruit strengthening fertilizer (summer and autumn fertilizer) is generally applied 10~15 days before autumn shoot germination, accounting for 20%~ 40% of the annual fertilizer application amount.

3. Shaping and pruning

The pruning of young trees should emphasize the principle of "wiping buds and controlling shoots" and master the principle of "removing early and keeping neat, removing less and keeping more". When most of the final shoots of the whole plant have 3~4 new shoots sprouting, the pruning should be stopped. Proper thinning off over-dense branches, all cut off winter shoots. The early fruiting trees should pay attention to cultivating short and strong spring shoots and autumn shoots, erasing summer shoots and winter shoots, thinning upright branches, leaving oblique branches or pulling branches. In full fruiting period, mature trees should retract fruiting branch group, flower and fruit dropping branch group and declining branch group in time, and cut off dead branches and diseased branches. For trees with too many backbone branches and serious crown closure, large branch pruning method can be used to prune, saw off the middle upright backbone branches and large branches, open "skylight" to introduce light into the bore (sawing large branches should be carried out in spring), adjust the yield of the next year by truncating or thinning the vegetative branches of summer and autumn shoots taken out in the current year, and truncate most branches or all branches on the basis of heavy thinning for leafless branches. The tree height is controlled below 3 meters. The formation of natural open-heart shape, thousand high 20-40 cm, 3~4 main branches in the trunk scattered distribution. The branch angle of the main branch is 30~45°, 2~3 auxiliary main branches are arranged on each main branch, and a number of lateral branches are appropriately arranged on the main branch and the auxiliary main branch.

4. Flower and Fruit Management

To promote flower bud differentiation, ring cutting can be carried out in early September to October, the width of ring cutting should be controlled at 0.1~0.2 cm, and it is appropriate to reach xylem deeply. For the fruiting mother branch, the inflorescence should be thinned first and then the bud should be thinned at the bud stage, the head should be pinched and the tail should be left in the middle, and 2~3 strong flowers should be thinned and weak flowers should be left, and the early summer shoots should be removed. After physiological fruit dropping in early May, the tree is divided into 2~3 times to keep fruit quantity, keep fruit evenly distributed, remove disease and insect fruits and abnormal fruits.

5. Suitable planting area city

Citrus can be planted in the adaptive area, but the minimum temperature in winter should not be lower than minus 8C. The mountainous area and the area with good drainage conditions are more suitable.

Well, the above is the cultivation point of red meat pomelo brought to you by the small series of soil flow net. I hope it helps. Like friends welcome to pay attention to earth drift net. We'll see you next time.
