Irrigation method enabling soil moisture content to be appropriate for mangos

Abstract

The invention discloses an irrigation method enabling the soil moisture content to be appropriate for mangos. The method comprises the steps that the soil moisture contents of the autumn shoot sprouting period, the flower bud differentiation period, the blooming and fruiting period, the fruit expanding period and the mature period are maintained to be 80%-90%, 60%-75%, 70%-80%, 80%-90% and 50%-75% respectively, trimming is carried out after fruit picking and before autumn shoot sprouting, 2-3 batches of autumn shoots are cultivated in the autumn shoot sprouting period, the soil moisture content is maintained at 80%-85% after the last autumn shoot sprouting, and if the soil moisture content is higher than 95%, roots are cut off to control water absorption; when drought happens in the flower bud differentiation period, watering is carried out once before blooming; when drought happens in the fruit expanding period, watering is carried out 10-15 days after flower drop and before physiological fruit drop; when drought happens in the mature period, watering is carried out within early 10 days of the mature period. Mango water need changes and the irrigation method in the whole growth period are firstly and comprehensively studied, scientific basis is provided for guiding agricultural water-saving irrigation, and the method has important guiding significance to improving self-management capacity of the mass peasants on mangos.

Description

technical field [0001] The invention relates to mango irrigation technology, in particular to the suitable soil moisture content and irrigation method of mango. Background technique [0002] Mangoes are propagated through nurseries on seedlings and are usually planted in spring. After planting, it is a young tree, and after about three years of growth, it becomes an adult tree, and the height and crown of the adult tree still continue to grow. Moreover, with the change of climate throughout the year, adult trees carry out life activities such as root growth, shoot bud growth, flowering and fruit setting, fruit development, flower bud differentiation, and leaf dormancy. The size of leaf area of ​​adult mangoes changes regularly throughout the year. Mangoes are generally harvested around July every year. Because the mangoes on the trees mature early and late, they are generally harvested in batches. From August 1st to July 31st of the next year can be regarded as a growth a...

AI Technical Summary

Problems solved by technology

Excessive water will make the vegetative growth of mango too vigorous, which is not conducive to flowering and fruiting. At the same time, it will aggravate the breeding and damage of diseases and insect pests. However, if the soil is too dry, it will cause flower and fruit drop
