Planting and management technology of guava

Guava is a kind of tropical fruit, which mainly grows in South China, also known as guava, plucking seed and chicken fruit. It has good taste and high nutritional value, and is favored by consumers. So how to manage it when planting? Let's take a look at the detailed introduction.

1. Soil management

Soil management is mainly loosening soil and mulching, loosening soil can improve soil structure, increase soil permeability, to facilitate the acquisition of roots, generally in the spring, it is necessary to loosen the soil in the whole garden. Loose soil is the only one outside the general radius of the crown, with a depth of about 15 cm. After loosening the soil for half a month, it can be watered. Mulching is for heat preservation and moisturizing, but also can prevent weeds, can cover straw or straw and other things after watering, can keep moisture in the dry season, but also can prevent the harm of underground pests, and enhance the content of soil organic matter.

2. Fertilization management

It is suggested to increase the application of organic fertilizer during fertilization, which can not only improve the soil structure and increase the content of soil organic matter, but also improve the disease resistance of plants and reduce the harm of diseases and insect pests. Generally, it is necessary to apply organic fertilizer twice a year, once in April, when it is time to plant flowering and fruit setting, which requires more nutrients, so it is necessary to re-apply fertilizer, a handful of 15-20 kg of rotten organic fertilizer per plant. Once in September, 2-3 kg of organic fertilizer and 0.5-1 kg of potassium sulfate compound fertilizer were applied to each grain, mixed evenly and then turned over deeply, and applied along the annular ditch or hole under the canopy.

3. Shaping and pruning

The pruning of young trees is mainly for shaping, and for the purpose of forming and expanding the crown as soon as possible, coring is carried out before and after the fruit-setting period to promote its germination signals, while the unfruited branches are left with a length of 30 cm to become fruiting mother branches. in addition, withered branches, residual branches, cross branches and branches of diseases and insect pests should be trimmed in winter. The pruning of fruiting trees is mainly controlled to achieve high yield, pruning lightly before fruiting and heavy pruning in full fruit period, so as to balance vegetative growth and reproductive growth.
