Problems solved by technology

[0018] Up to now, there is no literature or other reports on mango leaves spraying water during the lunch break to induce the opening of stomata to alleviate the lunch break, and to reduce the proportion of mango stomata during lunch break, and there are no orchards that implement this measure in actual production

Embodiment 1

[0029] 1) Select adult mango trees;

[0030] 2) Confirm the lunch break time of mango by observing the opening and closing ratio of stomata on the lower epidermis of mango leaves at different time periods;

[0031] 3) During the lunch break of mango stomata, spray water on the leaf surface continuously for 10 minutes, and then spray again after an interval of 30 minutes.

[0032] 4) No stomata open.

Embodiment 2

[0034] 1) Select adult mango trees;

[0035] 2) Confirm the lunch break time of mango by observing the opening and closing ratio of stomata on the lower epidermis of mango leaves at different time periods;

[0036] 3) During the lunch break of mango stomata, spray water continuously on the leaf surface for 20 minutes, and then spray the next time after an interval of 10 minutes, which can be sprayed 1-6 times.

[0037] 4) The average stomatal opening rate is 45%;

Embodiment 3

[0039] 1) Select adult mango trees;

[0040] 2) Confirm the lunch break time of mango by observing the opening and closing ratio of stomata on the lower epidermis of mango leaves at different time periods;

[0041] 3) During the lunch break of the mango stomata, spray water on the leaf surface continuously for 20 minutes, and then spray the next time after an interval of 20 minutes, which can be sprayed 1-6 times;

[0042] 4) The average stomatal opening rate is 57%.

Abstract

The invention relates to a method for reducing a noon break proportion of mango stomata. The method comprises the following steps: 1) selecting mango trees in an adult period; 2) determining noon break time of mangoes by observing opening and closing proportions of stomata of lower skins of mango leaves in different time periods; 3) continuously spraying water on leaf surfaces for 20 minutes or 30 minutes in a noon break period of the mango stomata, and spraying water again after 10 minutes or 20 minutes or 30 minutes; and continuously spraying water to leaf surfaces for 1-6 times; and 4) after continuous water spraying, the stomata in the leaves are opened and the leaves perform photosynthesis. The method can remarkably improve the opening number of the stomata in the leaves of the mangoes in the noon break period, enables an average stomata opening rate to reach 57%, has a good effect on reducing the noon break proportion of the stomata of the mangoes, thus enhances plant photosynthesis and improves fruit quality.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for reducing the mango stomata lunch break ratio, inducing the stomata to open, and enhancing the mango photosynthetic efficiency. Background technique [0002] Photosynthesis is known as the most important chemical reaction on earth. It is the process in which plants convert solar energy into chemical energy, synthesize inorganic substances such as carbon dioxide and water into organic substances, and release oxygen at the same time. Carbon dioxide is the raw material for photosynthesis. Within a certain range , the rate of photosynthesis increases with the increase of carbon dioxide concentration. In sunlight, the leaves of plants absorb carbon dioxide in the air through stomata for photosynthesis. Therefore, the opening of stomata is an important prerequisite for the normal progress of photosynthesis. However, at noon when the sunlight is strongest in summ...
