Problems solved by technology

[0004] In recent years, it has been found that O 3 Injured brown spots affect grape photosynthesis, thereby reducing grape fruit quality and yield
At present, there are research reports that the ozone damage can be alleviated by spraying ascorbic acid on the leaves, but the price is expensive and the effect is average.

Embodiment 1

[0025] Sodium bisulfite solution was sprayed in the vineyard of Shandong Agricultural University.

[0026] The annual "Cabernet Sauvignon" potted seedlings were selected to be planted in pots with a diameter of 25 cm and a height of 35 cm in mid-March. When the potted seedlings grew to 12-15 grape leaves fully unfolded in June, sodium bisulfite was used to relieve ozone stress. Control spraying clear water, the treatment is spraying 0.01wt% sodium bisulfite aqueous solution, spraying once every 5 days, after spraying twice, choose sunny morning, and the plants spraying clear water and spraying sodium bisulfite 6 put into the ozone fumigation shed for 110nL·L -1 Ozone fumigation treatment for 3 hours, then take it out and recover for 2 hours, and then measure the relevant indicators. The results in Table 1 show that sodium bisulfite can effectively alleviate the damage of ozone to grape leaves, and the grape leaves are slightly damaged, showing The chlorophyll content was hig...

Embodiment 2

[0044] Carry out implementation operation and spray sodium bisulfite solution on the large field of grape planting.

[0045] 1) During the grape planting and growth process, select a better light at around 14 o'clock in the afternoon, and use a sprayer to spray a sodium bisulfite solution with a concentration of 0.1 wt%, and spray evenly;

[0046] 2) Spray again after 7 days, so repeat spraying 4 times, carry out 110nL·L -1 Ozone fumigation treatment for 3 hours, then take it out and recover for 2 hours, then measure relevant indicators;

[0047] 3) to the chlorophyll content of grape, the MDA content in the grape root leaf was measured, and test result is consistent with embodiment 1, shows that blade spraying sodium bisulfite significantly alleviates the impact of ozone stress on grape leaf chlorophyll content, and shows that spraying The application of sodium bisulfite significantly alleviated the effect of ozone stress on the degree of membrane lipid peroxidation in grape...

Embodiment 3

[0049] Carry out implementation operation and spray sodium bisulfite solution on the large field of grape planting.

[0050] 1) During the growing process of grape planting, choose a place with better light around 17:00 pm, and the light intensity of the day is 800μmol·m -2 ·s -1 -2000μmol·m -2 ·s -1 , using a sprayer to spray a sodium bisulfite solution with a concentration of 0.009wt%, and spray evenly;

[0051] 2) Spray again after 6 days, repeat spraying 5 times in this way, and carry out 110nL·L -1 Ozone fumigation treatment for 3 hours, then take it out and recover for 2 hours, then measure relevant indicators;

[0052] 3) to the chlorophyll content of grape, the MDA content in the grape root leaf was measured, and test result is consistent with embodiment 1, shows that blade spraying sodium bisulfite significantly alleviates the impact of ozone stress on grape leaf chlorophyll content, and shows that spraying The application of sodium bisulfite significantly allevi...

Abstract

The invention provides a method for relieving the damage of atmospheric ozone to grapes by utilizing sodium bisulfite. The method comprises the following step: spraying a sodium bisulfite solution with the concentration being 0.001-0.1wt% once every other 5-7d in grape planting and growing processes. Due to the adoption of the sodium bisulfite solution with a certain concentration in the method for relieving the damage of atmospheric ozone to grapes by utilizing sodium bisulfite, provided by the invention, influences of ozone stress to the membrane lipid peroxidation degree of grape leaves areremarkably relieved, in addition, sodium bisulfite is low in price, wide in source and commercially-available, the method for relieving the damage of atmospheric ozone to grapes by utilizing sodium bisulfite is initiated, and researches on effects of the method for relieving the damage of the ozone are not proposed in the prior art, and therefore, the method provided by the invention is relatively pioneered, convenient to operate and simple in operation step and can be implemented without any specialized persons so as to be worthy of wide popularization and application.

Description

technical field [0001] The invention relates to the field of viticulture and planting, in particular to a method for alleviating the damage of atmospheric ozone to grapes by using sodium bisulfite. Background technique [0002] Tropospheric ozone (O 3 ) is a biologically harmful pollutant and one of the components of photochemical smog. In recent decades, due to the extensive use of fossil fuels and N-containing fertilizers, as well as vehicle exhaust emissions, the content of hydrocarbons and nitrogen oxides in the air has increased. These pollutants are affected by high temperature and strong light radiation. Under these conditions, photochemical reactions occur to generate secondary pollutants such as ozone. According to the information released by the China Environmental Monitoring Center, in 2017, the rate of ozone exceeding the national standard increased significantly, and the peak concentration increased significantly. Since 2013, among the three key regions (Beij...
