Psidium guajava standard cultivation method

Abstract

The invention belongs to the technical field of agriculture and particularly relates to a psidium guajava standard cultivation method. The method includes land selection and preparation, planting, water and fertilizer management, fruit tree management and disease and pest prevention and control. In water and fertilizer management, fertigation of water-soluble fertilizers and water into an irrigation ditch in a land selection and preparation process is performed, water-fertilizer integrated irrigation is realized, labor saving is realized, and soil hardening is avoided; in disease and pest prevention and control, natural preparations are adopted, so that pesticide residues and environmental pollution are avoided. The psidium guajava standard cultivation method has advantages that water-fertilizer integrated irrigation is realized, labor saving is realized, water and fertilizer effects can be prolonged, and water and fertilizers are saved; in addition, the fruit yield can be increased, fruit quality is improved, and public hazards and pollution are avoided.

Description

technical field [0001] The invention belongs to the technical field of agriculture, in particular to a standardized cultivation method of pearl guava. Background technique [0002] Guava, commonly known as guava, guava, and plucked fruit, is a perennial evergreen woody plant of the myrtaceae guava family. It is a fruit tree widely cultivated in tropical and subtropical regions. Guava is rich in protein, fat, sugar, multivitamins and trace elements. It is a good product for beauty and beauty, and has auxiliary curative effect on patients with high blood pressure, diabetes, obesity and poor stomach. Guava is native to South America and has been introduced to my country for more than 300 years. The guava production areas in my country are mainly distributed in Guangdong, Guangxi, Fujian, Hainan, and Taiwan. In addition, there are also a small amount of cultivation in Yunnan, Guizhou, and Sichuan. [0003] Taiwan pearl guava, also known as pearl guava, pearl guava, etc., is an ...

AI Technical Summary

Problems solved by technology

Due to the short period of introduction and cultivation of pearl guava in Guangxi, there are common problems in cultivation techniques such as lack of scientific management, random use of pesticides, large fluctuations in yield, low water and fertilizer utilization, and high labor consumption. Moreover, Guangxi is located in the south of my country and has a mild climate. Moist, suitable for the growth and reproduction of pathogenic bacteria, especially root-knot nematodes. Root-knot nematodes are common diseases and insect pests of guava. Root-knot nematodes have many pathogens and are highly contagious, and the transmission channels are complicated, so it is difficult to control. Root-knot nematode diseases serious

At present, guava planting and fertilization is mainly based on furrow fertilization, which consumes a lot of labor and the effect of fertilizer is slow; therefore, growers generally use water-soluble fertilizer spray irrigation or drip irrigation to solve the problems caused by furrow fertilization, which effectively solves the problem of labor cost and fertilizer The problem is that the effect is slow, but the water-soluble fertilizer has a fast effect, and the fertilizer consumption is large, and the sprinkler irrigation and drip irrigation are easy to cause soil compaction, affect the air permeability of the tree roots, and then affect the growth of fruit trees

For example, the invention patent with the application number 201110366648.7 discloses a planting method of pearl guava, which consists of plant ridge soil planting and shaping, water management, fertilization management and flower and fruit management. The soluble fertilizer applied is mixed with the required amount of water, and the water and fertilizer integrated drip irrigation method is applied to the soil of the guava tree through the pipeline; the water and fertilizer integrated drip irrigation method used in this patent effectively solves the problem of furrow application. The problems of high power consumption and slow action of fertilizers brought by fertilizers, but the problems of large fertilizer consumption and soil compaction in water and fertilizer integrated drip irrigation have not been fully resolved.
