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

Embodiment 1

[0032] Xuwen, Leizhou, Wuchuan in Zhanjiang and Dianbai in Maoming are the most suitable areas for mango production in Guangdong. The mango irrigation test was arranged to be carried out at the Wuchuan Irrigation Test Station in Zhanjiang City. The experiment was repeated for 11 years from 1991 to 2002, among which 1991-1992 was a young tree (2-year-old tree), 1992-1993 was a 3-year-old tree, 1993-1994 was a 4-year-old tree, ..., 2001- In 2002, it was a 12-year-old tree.

[0033] Wuchuan mango irrigation test includes water demand test and water-saving irrigation test. The test variety is Zihuamang, which is the main variety in Guangdong. The flowering period of Zihuamang is from mid-to-late March to early May. It is a late-maturing variety with strong adaptability, strong resistance to anthracnose, and resistance to pruning.

Abstract

The invention discloses a suitable soil water content and irrigation method for mangoes, specifically: maintaining the soil water content at 80% to 90% in the autumn shoot out period, flower bud differentiation period, flowering and fruit setting period, fruit expansion period and maturity period respectively , 60% to 75%, 70% to 80%, 80% to 90% and 50% to 75%; pruning after fruit picking and before autumn shoots sprouting; cultivating autumn shoots 2 to 3 times during the autumn shoots sprouting period, After the last shoot is pulled out, keep the soil moisture content at 80% to 85%. If it is higher than 95%, cut the root to control water absorption; if the flower bud differentiation period is dry, fill it with pre-flowering water once; Irrigate before physiological fruit drop; in case of drought during the ripening period, irrigate within the first 10 days of this period. The present invention comprehensively researches the change of water demand and irrigation method of mango in the whole growth period for the first time, provides scientific basis for guiding agricultural water-saving irrigation, and has important guiding significance for enhancing the self-management ability of farmers on mango.

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...
