Guava Planting and Management Techniques: Latest Tutorial
Guava is a fruit that is not very common in our daily life. Also known as the guava (Psidium guajava), it is a fruit tree widely cultivated in tropical and subtropical regions. It is rich in nutrients and suitable for both the elderly and children to eat. Nowadays it is also widely used in industrial processing and is a representative of a new type of fruit. Below, let's take a look at its planting and management techniques together with the editor.
1. Planting Environment
Most plants prefer a warm environment, and guava is no exception. Its most suitable temperature is between 20-35 degrees. If the temperature drops below zero, its young trees may freeze to death directly. It has no strict requirements for soil; sandy and clay soils can both support normal growth, but it prefers slightly acidic soil, and the soil pH value is best controlled between 5.5-6.5.
2. Propagation Methods
Guava has three propagation methods. One is cutting propagation: select a well-growing 2-3-year-old mother plant, choose branches with a diameter of 1.2-1.5 cm, cut them into small sections about 15 cm long as cuttings, soak the bottom of the cuttings in a solution of indolebutyric acid and sucrose for a period of time to promote rooting, and control the temperature between 28-32 degrees during cutting. It is best carried out between February and April. The second is air layering: select a 2-3-year-old mother plant, girdle 2-3 cm at a point 50 cm from the top of the branch, apply rooting powder to the girdled area, then wrap it with soil. After about two months, the girdled area will take root, and at this time it can be separated from the mother plant and replanted. The third is grafting; both bud grafting and branch grafting are acceptable, and it is best carried out in winter and spring. The scion should be selected from material of appropriate age, just peeled. Half a month before grafting, remove the leaves from the scion, cut it when buds sprout, then wrap and bind it for grafting. Untie it after one month, and plant it in the field after one year.
3. Timely Field Planting
Field planting is generally carried out in spring. The planting density depends on the variety. If it is an early-maturing variety and the soil at the planting site is relatively poor, a plant-to-row spacing of about 4 m is sufficient; if it is a mid-to-late-maturing variety and the planting site has sufficient fertility, keep the plant spacing at 4-5 m and the row spacing at 5-6 m. When planting, first plow the soil, then dig planting holes, apply base fertilizer, and after planting do not forget to water with rooting water. If the seedlings have many branches and leaves, part of them can be pruned appropriately to reduce unnecessary nutrient loss. After planting, set up some support structures to prevent the seedlings from lodging due to excessive wind.
4. Daily Management
During the young tree stage, fertilization should not be too heavy. In order to cultivate new shoots, topdressing can be applied twice according to the growth of the new shoots. The first time is when the new shoots grow to 40 cm, mainly applying some nitrogen fertilizer and urea. For adult fruiting trees, topdressing should be applied in stages, such as flower-promoting fertilizer, fruit-strengthening fertilizer, and fruit-preserving fertilizer, mainly based on compound fertilizer, and adding corresponding elements according to the needs of the growth stage. Water conditions should be determined according to the weather. If it is the rainy season, pay attention to spraying to avoid water accumulation that causes root rot. For young trees, do a good job of shaping and pruning to promote the formation of a tree canopy with good ventilation and light penetration.
