Embodiment 1

[0025] The cultivation method of selenium-enriched guava fruit tree of the present invention may further comprise the steps:

[0026] A. Site selection to build gardens: select saline-alkali land, and plant guava saplings with a spacing of 2.8m×2.8m;

[0027] B. Fertilizer and water management: Take the guava tree as the center of the circle, 18cm as the radius, dig a pit with a depth of 3cm to fertilize, and then cover the soil after fertilization. During the 1-3 years of guava tree growth, apply 0.4 calcium, magnesium and phosphorus to each plant. kg, 1 kg of selenium-enriched bio-organic fertilizer, 0.8 kg of calcium, magnesium and phosphorus, and 7 kg of selenium-enriched bio-organic fertilizer were applied to each plant from the fourth year; spray 2 kg of selenium-enriched liquid fertilizer on the leaves of guava trees in the early flowering stage; After fruiting, apply tea seed cake or peanut meal in March every year, 5kg per plant;

[0028] C. Bagging: After the fruit ...

Abstract

The invention discloses a method for cultivating selenium-rich guava fruit trees. The method includes the following steps of land selecting and orchard establishing, fertilizer and water managing, bagging, shaping and the like. Guavas cultivated with the method are good in taste, high in quality, beautiful in color and high in sweetness, the soluble solid, the sugar content and the sugar-acid ratio of guavas are obviously higher than the soluble solid, the sugar content and the sugar-acid ratio of marketed guavas, selenium-rich fertilizer is applied to guavas, guavas rich in selenium element are produced, and selenium-rich guavas are more beneficial to good health.

Description

technical field [0001] The invention belongs to the field of fruit tree cultivation, in particular to a method for cultivating guava fruit trees.
