Detailed Explanation of Key Techniques for Greenhouse Cherry Cultivation
Cultivating cherries in a greenhouse allows them to reach the market earlier and brings greater economic returns. How do you go about interplanting cherries for cultivation? Let us take a look together at greenhouse cherry cultivation techniques.
Greenhouse Cherry Cultivation Techniques
1. Choose suitable varieties. For greenhouse cherries, it is best to use excellent early-maturing varieties or early-to-mid-maturing varieties; short-branch varieties and varieties with strong self-fruiting ability can also be used. As for rootstock, dwarfing Gisela rootstock or Caiyang dwarf cherry rootstock can be chosen.
2. The land for building the greenhouse should be chosen in a geographical environment that is sheltered from the wind and faces the sun, with flat terrain, fertile soil, good permeability, irrigation available in drought, and drainage available in floods. Generally, in the 3rd year after planting, when the plant has formed a certain amount of flower buds, the greenhouse can be covered.
3. Inside the greenhouse, planting is generally done in double rows or three rows; those with larger canopies can be planted in single rows. Before transplanting, trim the damaged roots flat, remove root nodules, and carry out one sterilization treatment; after planting, irrigate thoroughly.
4. As for fertilizer, the base fertilizer should be sufficient, mainly decomposed organic fertilizer. Apply more nitrogen fertilizer during the bud break stage and early flowering stage. During the fruit swelling stage, mainly use phosphorus and potassium fertilizer.
5. During the growth period of cherry trees, try to keep the daytime temperature between 18-25°C, and at night about 5-15°C; there are differences at different stages.
6. The ratio of pollinator trees to the main cultivated variety is 1:4. When the cherry trees bloom, bees can be used for pollination, or artificial pollination can be adopted.
7. During the flower bud swelling stage, thin out flower buds, remove thin and weak flowers and overly dense flowers; when the flower quantity is large, use the method of supplementary pruning before flowering to regulate it. Fruit thinning is generally carried out 3 weeks after flowering, thinning out densely growing fruit, double-shoulder fruit, deformed fruit, small fruit under branches, etc., for a reasonable load, reducing nutrient consumption, so as to benefit young fruit growth and flower bud differentiation.
8. Prune the tree shape according to light conditions, and adjust the angle of the branches. During the continuous growth period of new shoots, pinch the tips continuously to control excessive growth.
When planting cherries in a greenhouse, multiple aspects need to be considered, and every growth factor must be well controlled.
