Problems solved by technology

Due to the lack of technologies and methods that can effectively regulate the flowering period of mangoes, people are helpless in the face of changeable weather, especially in the snow and ice disaster in southern China in 2008, the damage rate of mangoes was very high, and the harvest was almost lost

Embodiment 1

[0016] 1) Select 12-year-old trees with basically the same growth vigor and tree nutrition (test);

[0017] 2) Observe and determine the flowering time of the autumn mangosteen in the local area;

[0018] 3) Prepare a urea solution with a volume concentration of 4.8%;

[0019] 4) 7 to 10 days before the flower buds of the autumn mangosteen expand, spray the crown of the autumn mansia tree with a urea solution with a volume concentration of 4.8% until there are drops of water dripping from the tip of the leaves.

Embodiment 2

[0021] 1) Choose a three-year-old tree with a tree age of 13 years, whose growth potential and tree nutrition are basically the same (for testing);

[0022] 2) Observe and determine the flowering time of three-year-old mangosteen in the local area;

[0023] 3) Prepare a urea solution with a volume concentration of 5.0%;

[0024] 4) 7 to 10 days before the flower buds of the three-year-old mangosteen expand, spray the crown of the three-year-old mangosteen tree with a urea solution with a volume concentration of 5.0% until water drops drip from the tip of the leaves.

Embodiment 3

[0026] 1) Choose coconut mangosteen with a tree age of 14 years, whose growth potential and tree nutrition are basically the same (for testing);

[0027] 2) Observe and determine the flowering time of the mangosteen in the local area;

[0028] 3) Prepare a urea solution with a volume concentration of 5.3%;

[0029] 4) 7 to 10 days before the flower buds of mangosteen expand, spray the crown of mangosteen tree with urea solution with a volume concentration of 5.3% until water drops drip from the tip of the leaf.

[0030] The mango varieties also include: red ivory, liuxiang, tiger leopard tooth, olecranon, etc., all of which can delay the flowering period of the mango by the above method.

Abstract

The invention provides a mango tree florescence postponing method. The method includes the following steps that (1) neelum trees with the tree-age ranging from 12 years to 14 years and with the basically same growth vigor and tree body nutrition are selected; (2) the local precise florescence time of mango trees is determined; (3) a urea solution with the volume concentration ranging from 4.8% to 5.3% is prepared; (4) the urea solution with the volume concentration ranging from 4.8% to 5.3% is used for spraying mango tree crowns 7 days to10 days before mango flower buds are expanded till water drops down from leaf apexes. By means of the method, the mango tree florescence time is postponed by 15 days to 23 days, the peak of risks caused by late spring coldness can be avoided effectively, pollination fertilization is facilitated, the fruit-setting ratio is increased, and the yield is increased; the powdery mildew generation rate is reduced, the pesticide consumption is reduced accordingly, and the environment is protected beneficially.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for delaying the flowering period of mangoes. Background technique [0002] Late spring cold occurs every year in most mango producing areas in my country, and the damage rate of flower spikes varies greatly with the degree of late spring cold. In severe years, the harvest is almost complete. Since the mango planting fever appeared in South China and Southwest China, there has been a late-spring cold hazard almost every spring, resulting in a decline in mango production. The survey results from 2002 to 2006 showed that the damage rate of mango flower spikes in Yunnan Province reached 15% every year due to the damage caused by late spring cold. Due to the lack of technologies and methods that can effectively regulate the flowering period of mangoes, people are powerless in the face of changeable weather, especially in the snow and ice disaster in southern China...
