After the grapes were hit by hail disaster
On the afternoon of June 11th, Xunyi County in Xianyang City, Shaanxi Province suffered hailstorms lasting about one hour. Grapes, apples, peaches and other economic crops were seriously damaged, especially grape damage. What remedial measures should grapes take after a hailstorm? How to prevent hail disaster? The author interviewed Ma Zhifeng, professor of Yangling Vocational and Technical College on this issue, and gave the following suggestions:
Timely recovery
After the disaster, the fruit tree is weak and the disease resistance is reduced. After the disaster, special attention should be paid to spray protection. First, we must use thiobacillin and other bactericidal drugs in time to spray the orchard 2 to 3 times; the second is to wait until the next year before the budding to spray 5 to 7 Baume degree lime sulfur, and do the pests of different periods at the same time Anticipate prevention efforts to ensure that the trees recover as quickly as possible.
After the disaster, the severely damaged grapes should be promptly removed to prevent these fruits from continuing to absorb nutrients and affect the development of a well-developed fruit. Pay attention to clean up the damaged branches and leaves in time, and keep the leaves and light wounded fruits as much as possible. At the same time, spray foliar fertilizer on the grapes. The foliar fertilizer should be added with certain nitrogen fertilizers, such as urea, to promote the development and recovery of the trees; the amount of transpiration of damaged fruit trees will change. As a result, the orchards are arid, so fruit growers must pay attention to irrigation.
Prevention in the coming year
The site selection should be appropriate. When constructing the park, the more sheltered land should be selected. Serious discussions should be conducted with local experienced farmers to avoid hail belts. In the successive years, heavy-duty areas and hail-frequent belts can be used to establish a flood control network. Seriously listen to the local weather station's short-term weather forecast and make timely preventive remedies.
After the collection of pathogenic bacteria specimens, the disposable sampling cotton Swab should be completely inserted into the preservation solution to maximize the retention of pathogenic bacteria.
The collected specimens must be fresh and sent for inspection in time to avoid the death of pathogenic bacteria.
It is forbidden to use products with damaged packaging and expired expiration dates to prevent contamination.
Flexible combination: the number and type of swabs and sampling tubes can be combined arbitrarily.
Wide range of uses: It can be used for the collection, transportation and storage of new coronavirus, respiratory virus, hand, foot and mouth virus and other specimens.
Excellent quality: It has been verified by many medical institutions that the virus can still be detected after being stored in the preservation solution for 7 days at room temperature.
Easy to distinguish: the inactivated and non-inactivated preservation solutions are pink, which can effectively avoid sample addition confusion.
