After harvesting the sparse sweet cherries, the dense branches, weak branches and diseased branches should be removed or shortened to open the light path, enrich the branches and reduce unnecessary consumption, which is conducive to the differentiation and enrichment of flower buds and branches mature. Mainly aiming at the top strong tree and the closed tree, it should be carried out from top to bottom. When sparse branches of trees with too much upper branches are not allowed to be in one step, it should be carried out in two steps, each with 1 to 2 large branches at intervals of 1 month; the thin branches and invalid branches behind the inner chamber should be thinned at one time In addition, the dense tips on the back should be removed at one time.
Twisting Twisting is to twist the vigorous long branches and competing branches by 180 degrees during semi-lignification, weaken their growth, promote flower bud differentiation, and transform into fruiting branch groups. Those who are still growing vigorously after twisting should be continuously lightly topped to inhibit growth. Light topping on the extended tip can ease the tree vigor, but the secondary tip that occurs after topping should be uniaxially extended.
Topping Topping is the removal of the young part of the apex before the new shoots have not become lignified, which is called topping. It is one of the most used methods for pruning sweet cherries in summer. Topping young trees can encourage more branches to germinate and promote the formation of flower buds. It can play a role in saving nutrients, improving fruit setting rate and fruit quality when topping the trees in the early fruiting and full fruiting periods.
Lazhi pulls Qiangwangzhi to the place where there is space to make up for the shortage of backbone branches. It can accelerate the formation, delay the growth of the shoots, improve the light in the bore, and promote the differentiation of flower buds. In the vertical direction, the main branches should be kept at 80-90 degrees; overlapping branches can be pulled horizontally to the appropriate direction; the vertical distance of the main branches in the same direction should reach 80-100 cm.
Timely control to control the growth of the Wangshu tree after taking various summer shearing measures, it should be sprayed with 200-300 times paclobutrazol or 180-200 times PBO in a timely manner to control it. Wangshu sprayed 2 to 3 times to get a good suppression effect.

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.
