Embodiment Construction

[0011] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0012] Embodiments of the invention include:

[0013] The 5-year-old potted sweet cherry variety 'Zaodaguo' was used as the experimental material, and the low-temperature freezing injury experiment was carried out during the flowering period. When the sweet cherry 'Zaodaguo' was in full flowering stage, it was placed in an artificial climate chamber to simulate freezing damage during the flowering stage. The temperature in the artificial climate chamber was set at -2°C, and the low temperature treatment time was 4 hours.

[0014] The preparation method of described NaHS solution is successively weighed 1700mg KH 2 PO 4 , 19000mg KNO 3 , 200mg glycine, and 50mg 6-BA were placed in four 500ml b...

Abstract

The invention relates to a method for preventing freezing damage in cherry florescence. The method comprises: spraying NaHS solution on cherries in florescence in low temperature condition, the optimal concentration of the NaHS solution being 0.075 mmol / L. The method reduces damages on organs of cherry flowers by low temperature, and through detailed experiment design and analysis, an optimal spraying stage and spraying concentration are made clear. The method has great practical application significance on reducing waterlogging damage and reducing loss.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for preventing low-temperature freezing damage of cherry blossoms. Background technique [0002] Sweet cherries are not resistant to low temperature, and are extremely vulnerable to low temperature damage during the flowering period. Once the low temperature is encountered during the flowering period, the yield will be reduced, and the severe one will have no harvest, resulting in serious economic losses. Recently discovered H 2 S, like NO and CO, can be used as a gas signal molecule to regulate plant growth and adaptation to the environment, for example, external application of appropriate amount of H 2 S hydrogen sulfide can promote plant growth and seed germination, significantly increase the survival rate of Arabidopsis seedlings under drought conditions, reduce the degree of chlorosis of sweet potato leaves under osmotic stress, improve the survival rate and regeneration...
