Summer is coming, the rain is constantly. For natural disasters such as thunderstorms and hail, there is currently no good way to prevent it. Although it cannot prevent the occurrence of thunderstorms and hail, it can actively learn the orchard management measures after thunderstorms and hail, so that the fruit trees can recover from the disaster as soon as possible and reduce losses.
Clean up orchards and reduce pathogens
First, timely clean up the hail, fallen leaves and fruit falling in the orchard. For orchards with silt and stagnant water after the disaster, the accumulated water should be drained in time to remove the mud and expose the dried branches; the second is the severely damaged orchard with broken branches and broken leaves, comprehensively clearing the ground leaves, falling fruits, and digging deep Buried, remove the fruitless fruit, retain some of the fruit of the small pit, and reduce the loss of the year.
Spraying drugs in time to prevent diseases
Spraying fungicides such as thiophanate-methyl, bactericidal, bactericidal, bactericidal, carbendazim, etc. every 10 to 15 days, and spraying 2 to 3 times to prevent the invasion of bacteria.
Loose soil, roots and trees, thunderstorms, hail, weather, should be continuously tumbling 2 to 3 times, in order to disperse excess water in the soil, improve soil permeability, restore root physiological activities, and thus achieve roots and trees purpose.
Topdressing and restoring, restoring vitality
The first is foliar spray fertilizer to solve the problem of insufficient nutrient in the tree; the second is to apply balanced NPK compound fertilizer in the underground, 0.5~1 kg per plant. After the fruit trees are restored to life, the fertilization is mainly based on farmyard manure, and the appropriate fertilizer is applied. In the case of drought, combined with fertilization for irrigation.
Apply medicine to protect the wound
After the main tree, main branches and some of the larger side branches of the cortex are injured by hail, the smashed rotten skin should be cut off in time, and the agents such as rot and medicinal herbs should be applied to promote wound healing. For wounds with an area of ​​more than 1 cm 2 , while applying the medicine, plastic bags are also used to accelerate the healing of the wound.
Pruning branches, reasonably staying
After the disaster, the broken branches should be cut off in time. For the branches with high density, heavy weight and unrecoverable damage, the branches should be cut off from the base or intact, and more stubborn branches or branches should be left to avoid large wounds. After trimming, the cut should be sealed to prevent dry rot. Due to the more wounds in the tree, the leaf buds under the wound will germinate rapidly. The newly sprouted branches should be properly preserved according to the tree shape to make up the vacancies of the branches. Other sprouting trees that disturb the tree shape and the sprouts at the base of the tree are all eliminated. .
Manage flowers and fruits, improve quality
In the event of a disaster, the severely damaged fruit will be removed in time to save nutrients and restore the tree as soon as possible. Other late fruit trees make up the bag. The causal tree leaf is interrupted and broken, and some fruit bagging is broken. The fruit is directly exposed under the scorching sun, which is prone to sunburn. It should be supplemented with bags to improve fruit quality and reduce losses.
Strengthen prevention and control, restore the tree
Fruit trees are weak after the disaster, and their disease resistance is reduced. Pay special attention to spray protection. First of all, it is necessary to spray the orchard with bactericides such as thiophanate-methyl for 2 to 3 times in a timely manner; secondly, spray 5 to 7 waves of sulphur sulphur mixture before germination to the next year, and do a good job at different times. Pest and disease prediction and prevention work to ensure that the tree body is restored to a healthy state as soon as possible.

Urinalysis test strips refer to test strips that test for bilirubin, urobilinogen, ketone bodies, ascorbic acid, glucose, protein (albumin), blood cells, PH, etc. in urine.
Detection principle
1. pH: The pH value in the range of 5-9 is measured by the pH indicator, and the pH value of the fresh urine of a normal person is between 5-7.
2. Nitrite: The reaction is based on the reduction of nitrate to nitrite by Gram-positive bacteria in the urine. The nitrite reacts with p-aminobenzenesulfonic acid to form diazonium compounds, which are then combined with N-(1-naphthalene) )-3 aminopropanesulfonate combined with a pink color.
3. Glucose: According to the reaction principle of glucose oxidase, glucose oxidase specifically oxidizes glucose to generate glucuronic acid and hydrogen peroxide. Under the action of hydrogen peroxide, hydrogen peroxide oxidizes the indicator and turns color. .
Classification
Urinalysis test strips are divided into visual series and machine series. The visual inspection series is divided into several models according to different inspection items; the machine inspection series is divided into several models according to different applicable instruments.
1. Classification by measurement method
1) Visual inspection series
When observing the result, compare the color with the standard color code within the time specified on the color code, judge and read the result.
2) Machine test series.
For instrument operation, refer to the instruction manual of the Urine Analyzer used.
2. According to the number of measurement items
There are single-item, 2-item, 4-item and multiple test strips. Currently, 10-item or 11-item multiple test strips are most commonly used in hospitals.
3. Classification by structure
Urinalysis test strips with single-layer membrane structure and multi-layer membrane structure.
