A method to ensure that mango flowering period avoids low temperature and rainy weather in southern Guangxi

Abstract

The invention discloses a method for ensuring the flowering period of mangoes in southern Guangxi to avoid low temperature and rainy weather. The target period of mangoes' flowering period is determined as March 25-April 20th every year, and the flowers are picked in batches within the determined time period to delay the flowering period The purpose is to make most of the mango flowering period fall within the set target period, including the following steps: (1) On December 20‑30 of the year, any flower spikes that are at the end of elongation to the florets that have opened, All are removed from the base; (2) on January 20-30 of the following year, the flower spikes and flower buds with a length of more than 3cm are all removed from the base; (3) the flower removal on February 15-25 of the next year depends on different situations. way defloration. The present invention forms multiple batches of flowering periods by picking flowers in batches at regular intervals, so as to delay and prolong the flowering period of the whole mango tree to avoid the influence of low temperature and rainy weather in the flowering period, thereby obtaining high and stable yields.

Description

technical field [0001] The invention relates to a method for ensuring that mangoes avoid low temperature and rainy weather during flowering, in particular to a method for ensuring mangoes avoid low temperature and rainy weather during flowering in southern Guangxi. Background technique [0002] The climatic conditions required for mango pollination and fruit setting rate are high during the flowering period and for a period of time after flowering. In the southern part of Guangxi, long-term low temperature and rain or cold weather in late spring during the flowering period of mangoes is the main reason for low yield or even loss of mango. Therefore, the regulation of mango flowering period is very important for the high and stable production of mangoes in southern Guangxi. Usually mangoes delay the flowering period by removing the flower ears in batches to make the lateral buds form flower buds again. Picking flowers in batches can form multiple batches of flower ears with...

Problems solved by technology

[0003] First of all, the above method is only suitable for the regulation of mango flowering in the dry and hot climate area of ​​Baise, Guangxi "Youjiang River Valley", but not for the southern part of Guangxi, where low temperature and rainy springs occur more frequently, last longer, and have higher humidity. Years of observation records show that In southern Guangxi, the mango flowering period is still extremely vulnerable to low temperature and rain before March 25, which has a huge impact on high and stable yields

Secondly, the "three-three system" method of processing flower spikes is relatively mechanical, and does not take into account the specific circumstances that climate change in different years has different effects on the growth and development of existing flower spikes and branch buds.

Furthermore, the "Three-Three System" treatment of flower spikes is more complicated: when picking flowers in mid-to-late January, they are cut off together with the dense buds; when picking flowers in early February, they are removed from the base; 1-2 cm or keep 2-3 branches; the "three-three system" method of dealing with flower spikes is not a complete sense of "picking flowers"
