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

The method in a kind of Tui Chi Mango fruit flowering stage

 

Technical field

The present invention relates to field of plant growing technology, specifically the method in a kind of Tui Chi Mango fruit flowering stage.

Background technology

Large portion of China divides Mango fruit producing region to have cold in the late spring to occur every year, and Hua Sui rate of being injured has very big-difference with cold in the late spring occurrence degree difference, the serious time occurs, almost has no harvest.South China, southwest, since Chu Xian Mango fruit plantation heat, have almost all occurred that cold in the late spring endangers, Zhi Shi Mango fruit production declining annual spring.2002 ~ within 2006, the survey showed that: due to cold in the late spring harm, Yun Nan economizes Mango fruit flower fringe rate of being injured and reaches 15% every year.Can the techniques and methods at effective Tiao Kong Mango fruit florescence owing to lacking, people seem helpless in face of changeable weather, particularly very high in the colored fringe of southern china ice disaster Zhong Mango in 2008 fruit rate of being injured, and almost have no harvest.Therefore, invent a kind of push away slow Mango fruit the florescence with avoid cold in the late spring harm method, Mango fruit actual production and industry develop in a healthy way in there is special value and significance.

Summary of the invention

The object of this invention is to provide a kind of can effectively Tui Chi Mango fruit the florescence method.By postponing the florescence, reach the object effectively avoiding cold in the late spring harm.

The method in Tui Chi Mango of the present invention fruit flowering stage is carried out according to the following steps:

1) age of tree is selected 12 ~ 14 years, growth potential and the basically identical autumn Mango of trunk infusion, 3 years Mango, the fragrant Mango of coconut palm (" autumn Mango ", " 3 years Mango ", " the fragrant Mango of coconut palm " are Mango fruit variety names);

2) Que Ding the accurate flowering time of Mango fruit in locality;

3) urea liquid of dose volume concentration 4.8 ~ 5.3%;

4) before Mango fruit bud expands 7 ~ 10 days, Mango fruit tree hat is sprayed, until blade tip has lower of the globule with the urea liquid of volumetric concentration 4.8 ~ 5.3%.

Urea is a kind of material of Promoting plant growth, within the scope of finite concentration, and energy Promoting plant growth; Content exceedes or lower than suitable scope, plant can not normal growth.The present invention utilizes the characteristic of urea, when being determined to urea concentration 4.8 ~ 5.3% after a large amount of experiment that Tui Chi Mango is really carried out flowering stage, urea liquid is sprayed to Sheng Chang Zhong Mango fruit tree hat, the effect (i.e. delaying anthesis effect) pressing down Mango fruit tree branch processed, leaf, blastogenesis length can be played, can not to making into the consequence that Mango fruit blade Lao Ye is burnt, young leaves is lethal.

Following good effect can be reached by method of the present invention:

1, Mango fruit bud expands first 7 ~ 10 days, and after the urea liquid with 4.8 ~ 5.3% sprays Mango fruit tree hat, Mango fruit flowering time is postponed 15 ~ 23 days, can effectively avoid cold in the late spring hazard boom.

2, to bloom neat and consistent, be conducive to Pollination Fertilization, improve percentage of fertile fruit, increase yield.

3, Post flowering, the hermaphrodite flower quantity in each inflorescence increases, and reaches 20 ~ 35%, is conducive to Zeng Jia Mango fruits quantity, improves output.

4, after postponing the florescence, powdery mildew incidence declines, and then reduces pesticide dosage, is conducive to protection of the environment.
