Strengthen the management of autumn and winter rapeseed

First, we must strengthen management and ensure the effective area of ​​rapeseed. For late rape sowing due to the effects of drought and flooding, seedlings must be seeded or replanted in a timely manner to ensure full seedlings, so as to ensure an effective area for rapeseed production this year. Weeding, seedlings, and grass seedlings should be promptly prevented for seeded rape seedlings. The phenomenon of absurd seedlings. Second, we must increase pest control efforts, this year, high temperature and little rain, locusts and cabbage caterpillars occur in general and more serious, all localities should pay close attention to rape prevention and control work to ensure the normal growth and development at seedling stage, reduce the degree of victimization; , Years ago, according to the growing trend of rape, scientific winter fertilizer, promote winter hair. In the upstream part of the plot, early, early development, and growing preference for plots should be promoted in order to prevent the phenomenon of Wang Miao. After the year, the fertilizer will be applied in a timely manner. Generally, no fertilizer will be applied on February 15th. Mushi can apply about 15 kg of calcium phosphate, urea 3-5 kg. At the same time, it is necessary to spray a sufficient amount of boron fertilizer on foliar fields with insufficient boron fertilizer at the end; Fourth, we must pay attention to the comprehensive prevention and treatment of sclerotium disease. We must adopt a comprehensive prevention and control policy of "prevention as the main and medicine as the supplements." We must open the "three channels" well in advance of the year and clear the drains in time after the year. At the same time, we must remove old leaves, yellow and diseased leaves, and increase rapeseed. Tian's air and light transmission reduce the source of infectious diseases. For the diseased rapeseed, we must promptly use low-toxicity and high-efficiency nucleus purpura and other pesticides, spray and control in sunny days to reduce the harm.

Reagent Strips For Urinalysis

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.
