Method fast discriminating peach blossom bud freeze injury

Abstract

The invention discloses a method fast discriminating peach blossom bud freeze injuries; the method comprises the following contents: randomly selecting 5-6 areas in a peach plantation site under low temperature frost influences, and randomly selecting peach trees of certain number in each area; setting grading standards according to the peach blossom bud freeze injury levels; combining peach blossom bud freeze injury indexes with the grading standards so as to investigate and record the freeze injury conditions of the selected peach blossom bud; fusing said data so as to obtain the freeze injury level of the selected peach blossom buds. Compared with the prior art, the method can fast and effectively monitor the peach blossom bud freeze injury conditions, and can carry out anti-freeze treatments for the frozen buds; the method can detail-grade the peach blossom bud freeze injury levels, and can fast determine the peach blossom bud freeze injury conditions, thus reducing freeze injury, reducing blossom bud freezing death, and improving the blossom bud cold resistance.

Description

[0001] Technical field: [0002] The invention relates to a method for rapidly identifying frost damage of peach flower buds, belonging to the technical field of planting. [0003] Background technique: [0004] The impact of low temperature on plants is not only in the external form of performance, but also has a great impact on the physiology and biochemistry of cells; a large number of research results have revealed and confirmed that the damage of low temperature to the cell membrane system is the fundamental mechanism of plant cold damage, and the main reason is due to freezing. The resulting dehydration of the cell leads to the transformation of the double layer of the cell membrane to the hexagonal phase and the rupture of the membrane. The freezing damage is mainly manifested in the following aspects: 1) the cell membrane is destroyed, and a large amount of solute in the membrane leaks out; 2) the flow of cell protoplasm slows down or 3) Water metabolism disorder, water...

[0004] The impact of low temperature on plants is not only in the external form of performance, but also has a great impact on the physiology and biochemistry of cells; a large number of research results have revealed and confirmed that the damage of low temperature to the cell membrane system is the fundamental mechanism of plant cold damage, and the main reason is due to freezing. The resulting dehydration of the cell leads to the transformation of the double layer of the cell membrane to the hexagonal phase and the rupture of the membrane. The freezing damage is mainly manifested in the following aspects: 1) the cell membrane is destroyed, and a large amount of solute in the membrane leaks out; 2) the flow of cell protoplasm slows down or 3) Water metabolism disorder, water absorption capacity and transpiration rate are significantly reduced; 4) Photosynthetic rate is weakened, chloroplast decomposition is accelerated, chlorophyll content is reduced, and enzyme activity is affected, so the photosynthetic rate is significantly reduced; 5) Respiration rate fluctuates greatly; 6 ) Decomposition of organic matter is greater than synthesis; at present, plant antifreeze is mainly used for protection, but the protection effect is poor, and the plants are severely frozen. There is an urgent need for a method for quickly identifying frost damage to peach blossom buds and antifreeze measures
