Embodiment 1

[0048] A method for preventing and treating grape sunburn, comprising the following steps:

[0049] 1) Ecological governance:

[0050] ①Apply Deflavin microbial fertilizer;

[0051] ② Apply Woyiduo microbial fertilizer;

[0052] 2) Agricultural control:

[0053] ① Increase the application of organic fertilizers, keep the soil loose, increase its water retention performance, promote strong root systems, and enhance tree vigor, while avoiding excessive application of available nitrogen fertilizers;

[0054] ②Cultivation management should be strengthened, and low-lying orchards should pay attention to drainage after rain to reduce the groundwater level;

[0055] ③ For varieties prone to sunburn, more attention should be paid to shelf surface management;

[0056] 3) Physical control:

[0057] When pruning in summer, a few leaves should be properly left for shade near the fruit ears, and excess leaves in other parts should be properly removed. For varieties prone to sunburn, bag...

Abstract

The invention relates to a prevention and control method for grape sunscald, which comprises following steps: (1) ecological management: 1) applying Difulai microorganism fertilizer; and 2) applying HYT (High Yield Technology) microorganism fertilizer; (2) agricultural prevention and control: (3) physical prevention and control: during summer pruning, properly reserving plural leaves near to clusters for shading while properly removing excessive leaves at other parts, wherein for varieties easily subjected to the sunscald, cluster bagging is performed as soon as possible to avoid sunburn, but ventilation of fruit bags should be noticed, for the fruit bags with poor ventilation, one corner of the lower part of the fruit bag should be cut off, to promote ventilation and cooling, thus effectively preventing the grape sunscald. The agricultural prevention and control, physical prevention and control and other measures are adopted for comprehensive prevention and control to reduce the average morbidity of the grape sunscald, increase yield, obviously improve the grape grade and obtain well economic benefits.

Description

technical field [0001] The invention relates to a method for preventing and treating grape sunburn, and belongs to the technical field of plant protection. Background technique [0002] Sunburn of grapes In addition to the damage caused by powdery mildew and the close arrangement and excessive extrusion of fruit grains, grape cracking is also related to excessive changes in soil moisture. This phenomenon mainly occurs after fruit sizing. The fruit cracks, and sometimes the seeds are exposed, and the cracks are easily infected with mold and rot, losing economic value. [0003] It is mainly due to the excessive change of soil moisture in the later stage of fruit growth and the sudden increase of fruit turgor. If the early stage of grape growth is relatively dry and early, and the fruit encounters heavy rain or flood irrigation when it is near maturity, the roots absorb water from the soil and transport it to the fruit grains through the fruit brush. The cell activity of the...
