Now more and more fruit farmers are engaged in guava cultivation, how can the cultivation be productive?

Guava, also known as guava, is a perennial tropical evergreen tree of the Myrtle family Guava. Guava is native to the American continent. Since the American continent was discovered later, there is no consistent evidence for its origin. Guava was introduced to China very early, being introduced and cultivated in China around the 17th century. At the beginning of its introduction, it was only used for sporadic cultivation and did not form a scale.

Since modern times, with the development of our economy and the rich nutrition and good taste of guava, the planting area of guava has been gradually expanded. At present, there is planting industry in South China, among which Guangdong, Guangxi, Sichuan, Hainan, Taiwan, Fujian and other provinces have a large planting area. In recent years, growing fruit from south to north has become popular. Henan, Shandong and other places also have a small number of facilities can not form a scale of cultivation.

At present, more and more farmers are engaged in guava planting. According to the analysis of relevant experts, the planting area of guava is not saturated. How to improve the yield and quality of guava has become the guarantee to improve farmers’ income. Although guava is highly adaptable, in order to achieve high yields, Einon believes fruit growers should do the following:

No matter what kind of fruit trees are planted, the selection of seedlings is very important for the selection of good varieties. It largely determines the yield and quality of guava in later stages. Therefore, fruit farmers should choose high-quality guava seedlings with high yield, good disease resistance, strong stress resistance, strong plants, disease-free and suitable for local environment cultivation, which is the premise and preparation for high yield.

Reasonable garden construction and good initial orchard construction are also the basic guarantee of guava high yield. Garden construction of fertile soil, good permeability, rich in organic matter of weak acid fertile soil. The park should have good drainage and irrigation capacity, and the planting density should be reasonable. Of course, after the transportation and field work had better have convenient transportation. Ynon also advises fruit growers to reapply fermented organic fertilizer before planting, which is very beneficial for higher yields and field management later on.

Fine field management, both during tree breeding and fruit production, requires scientific planting and fine field management to achieve high guava yields. Reasonable pruning: Tree types should be determined early in the breeding season. Fruit trees should be pruned in winter and during the growth cycle to maintain tree vitality and prevent the occurrence of pests and diseases.

Appropriate fertilization: The guava should be fertilized according to the different fertilizer needs at different stages of the tree age and growth cycle. Young trees should be fertilized to ensure that fruit trees are strong but not flourishing. Nitrogen fertilizer should be controlled in fruit trees. Fertilization should be paid attention to after fruit collection. Attention should be paid to the difference of fertilization in flower and bud stages, and attention should be paid to foliar fertilization in time.

Guava has a longer growth period than normal fruit, and the nutrients in the trunk are used up quickly, so they must be supplemented with lots of organic fertilizers. In general, it needs to be used about 3 times per year to keep the trunk depleted. In the later stages of fruiting, the amount of nutrients consumed inside the trunk varies because of the amount of hanging on each trunk. So when we replenish fertilizer, we should treat it on a per-tree basis and not confuse it.

Guava flowers and produces fruit all year round, so it also uses a lot of water. If irrigation is not available, it can be very affected. Therefore, it is necessary to maintain irrigation operation, especially in autumn and winter, and irrigation operation cannot be stopped. Irrigation is performed approximately every 10 days until harvest. However, moisture should not be excessive to avoid moisture accumulation and fruit falling damage.

Strengthen the management of pollination period and adopt manual pollination when necessary to increase the yield of guava. Clean up the orchard in time to ensure the cleanliness of the orchard, remove diseased branches, dead branches and fallen leaves in time to prevent the occurrence of diseases and improve the yield of guava.

In the later stage of the fruit, when the fruit has grown to about 3 cm, the undeveloped fruit is removed to avoid wasting the well-developed fruit by timely bagging, to ensure the fruit is beautiful and to reduce insect infestation. So that the fruit can be picked safely.

Actively prevent and control diseases and insect pests. The occurrence of pests and diseases has a great impact on the yield of guava, which must be actively controlled. The main pests and diseases of guava include anthracnose, brown spot, leaf blight, Drosophila melanogaster, root-knot nematode and so on. The occurrence of diseases is closely related to planting management.

Therefore, comprehensive measures should be taken to combine agricultural control with biophysical control in pest control. In the process of chemical control, attention should be paid to clear the garden in winter, preventive drug use in advance, and continue to cross drug use after the occurrence of pests and diseases. In order to reduce the occurrence probability of pests and diseases, improve the yield of guava.

Of course, Xiaobian again only introduces the outline measures for high-yield guava. In planting and production, fruit farmers should pay attention to more details, only through systematic and refined planting can achieve the goal of high yield.
