Detailed Explanation of Sweet Cherry Dwarfing and High-Density Planting Techniques

The sweet cherry is not a native fruit tree of our country; it is a new fruit variety introduced into our country. At present, it is grown in many places in our country, such as Heilongjiang, Jilin, eastern Liaoning, Henan, Zhejiang and other places. However, the current sweet cherry planting techniques are not yet perfected, so sweet cherry yields are not high. So to increase sweet cherry yields, the first thing we need is sweet cherry dwarfing and high-density planting. Let's learn about it together below.

1. Ridge soil and seed selection

Before planting, preparing the ridge soil is the most basic condition for dwarfing and high-density planting. First, we need to loosen the soil by plowing, then pour in an appropriate amount of river sand and mix it evenly with the soil to make ridge-shaped mounds of soil. This will preserve nutrients and moisture for subsequent planting; at the same time, adding river sand to the soil is only meant to reduce the plant's pests and diseases and enhance the plant's resistance. Next is to select rootstock seeds; generally the wild cherry (Prunus pseudocerasus) is used as the mother tree, and after the seeds have been stored at low temperature, they are soaked in warm water to promote germination.

2. Transplanting management

When the treated seeds show a white sprout, we can transplant them into the prepared ridge soil for planting. When planting, pay attention to the direction of the white sprout to avoid putting it in upside down, which would affect seedling emergence. After planting, we should spread a layer of crushed medicinal residue on the ridge soil mound, which is beneficial for the seedlings to grow into saplings.

3. Grafting treatment

When the sapling's thick part reaches about two cm, we can carry out grafting. The grafting method is similar to that of other fruit trees, so the editor will not go into detail here. But after grafting, we need to dig a soil mound about thirty to forty cm deep beside the ridge soil mound, which helps increase the survival rate of the graft.

4. Shaping and pruning

Shaping and pruning is the key in sweet cherry dwarfing and high-density planting techniques. Generally, after shaping, we train the sweet cherry tree into a Y shape, which allows the sapling to maintain good ventilation and light penetration and can promote the sweet cherry sapling to flower and bear fruit. Second, during the young tree stage, branches and leaves should be pruned reasonably to promote the formation of the canopy and ensure the growth height of the sapling. After fruiting in the later stage, we need to control the number of fruiting mother branches, and at the same time master the distance between the main trunk and each branch, pruning according to scientific pruning principles.

5. Protecting flowers and fruits

The work of protecting flowers and fruits is mainly to improve the yield and quality of sweet cherries. Protecting sweet cherry flowers and fruits requires management of fertility and water, pollination configuration, artificial pollination, flower and fruit thinning, plant hormones and various other aspects. Only when all aspects are carried out correctly will the sweet cherry yield naturally be high. In particular, flower and fruit thinning is a step that many growers overlook, so everyone must carry out flower and fruit thinning reasonably, so as to reduce losses caused by physiological fruit drop.

The above methods not only can increase sweet cherry yields, but also can make full use of land resources. At present, because planting techniques are not perfected, the utilization rate of land resources and yields are not high, which has also caused a great impact on growers' economic returns.
