Embodiment 1

[0020] Example 1 Preparation and application of leaf surface anti-transpiration water retention agent for flue-cured tobacco.

[0021] refer to figure 1 , the preparation of leaf surface anti-transpiration water retention agent for flue-cured tobacco:

[0022] (1) 2wt% Ca 2+ Concentration suspension: Weigh 28 grams of quicklime in a 100ml beaker, add deionized water to dissolve, and finally set the volume to a 1000ml volumetric flask, shake and mix well.

[0023] (2) Preparation of leaf surface anti-transpiration water retention agent for flue-cured tobacco: mix the prepared suspension according to the volume ratio

[0024] Ca 2+ Suspension: EM stock solution: molasses: Ca(NO 3 ) 2 solution (wherein 0.5wt% Ca 2+ ):distilled water in a volume ratio of 2.5:1:1:0.6:3.5, and put it into a 37°C incubator to ferment for 7 to 10 days until most of the sediment dissolves, take it out, and dilute it to 1wt‰ (Ca 2+ ).

Embodiment 2

[0028] Example 2: Preparation and application of leaf surface anti-transpiration water-retaining agent for flue-cured tobacco.

[0029] The preparation method and application method of the leaf surface anti-transpiration water retention agent for flue-cured tobacco are the same as in Example 1, the difference is that in the preparation of the water retention agent, Ca 2+ Suspension: EM stock solution: molasses: Ca(NO 3 ) 2 solution (wherein 0.5wt% Ca 2+ ):distilled water=3:1.5:1.5:0.5:4.

Embodiment 3

[0030] Example 3 Preparation and application of leaf surface anti-transpiration water retention agent for flue-cured tobacco.

[0031] The preparation method and application method of the leaf surface anti-transpiration water retention agent for flue-cured tobacco are the same as in Example 1, the difference is that in the preparation of the water retention agent, Ca 2+ Suspension: EM stock solution: molasses: Ca(NO 3 ) 2 solution (wherein 0.5wt% Ca 2+ ): The volume ratio of distilled water is 3.5: 2: 2: 0.4: 4.5.

Abstract

The invention discloses a leaf surface anti-transpiration water retention agent for flue-cured tobacco, which comprises components with the following volume ratio: Ca 2+ Suspension: EM stock solution: molasses: Ca(NO 3 ) 2 Solution: distilled water=(2.5~3.5): (1~2): (1~2): (0.3~0.8): (3~5). The present invention uses EM stoste, molasses, distilled water, quicklime and Ca(NO 3 ) 2 The main raw materials are mixed and fermented, and the ratio with the best anti-transpiration effect is selected. By combining biological water retention technology and chemical water retention technology, the special anti-transpiration water retention agent for flue-cured tobacco can inhibit leaf transpiration and soil evaporation. It enhances the drought resistance ability of flue-cured tobacco, promotes the growth and development of flue-cured tobacco, and improves the yield of flue-cured tobacco and the utilization efficiency of irrigation water and rainfall. The anti-transpiration and water-retaining agent for leaves specially used for flue-cured tobacco is more effective when used in combination with soil anti-transpiration agent.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, and in particular relates to a leaf surface anti-transpiration water retention agent specially used for flue-cured tobacco. Background technique [0002] At present, in the field of flue-cured tobacco water saving and drought resistance technology, there have been many reports on measures to improve agricultural water use efficiency, such as rainwater storage, soil moisture conservation, combination of canals and wells, agronomic water saving and drought resistance measures, and so on. Water-saving and drought-resistant technology has developed from the initial improvement of water delivery efficiency and irrigation efficiency to the dynamic optimal allocation of water in the entire flue-cured tobacco planting area, the optimal allocation of irrigation water at different growth stages during the growth period of flue-cured tobacco, and the use of changes in the physiological indicators of f...
