Lishui, Zhejiang Province successfully cultivated water-saving and drought-resistant hybrid rice

A new combination of water and drought combined water-saving and drought-resistant hybrid rice has recently been successfully cultivated in Lishui, Zhejiang. At present, the Lishui Agricultural Research Institute is actively working with the Shanghai Center for Agricultural Biology to develop and apply water-saving and drought-resistant hybrid rice varieties.
The advantage of this combination of paddy rice and rice that has been successfully cultivated in Yeosu is that it can save a lot of water. Under the premise of assuring similar production, 700 to 900 cubic meters of water are needed per mu for ordinary rice planting, while water-saving and drought-resistant new varieties need only 200 to 300 cubic meters of water per mu, saving more than 60% of water. Experiments have shown that under the condition of water cultivation, the yield of “II You 628” is almost the same as that of traditional hybrid rice, and the yield per mu is about 600 kg. However, under conditions of severe water shortage, the hybrid rice of other varieties will all die. The output of "II You 628" can still reach more than 300 kg.
The study by the Lishui City Agricultural Institute began in 1998. Using a combination of modern biotechnology and conventional breeding techniques, they selected new combinations of water-saving and drought-saving water-saving hybrid rice varieties. A group of rice varieties with strong drought resistance and superior rice quality were successively bred and used in succession. Demonstration of outstanding performance. In the Yedian Village demonstration plantation area in Shuqiao Township, Qingtian County, the rice planted by villager Xu Baocai suffered from high temperature and dry weather for 45 consecutive days in 748 months of last year, and 80% of the other rice varieties in the village. All died, and his 10 mu “II You 628” rice yield still reached 450 kg.
Luo Lijun, director of the Shanghai Center for Agricultural Biology and Genetics, believes that the “II You 628” hybrid rice successfully grown in Yeosu will reduce irrigation in paddy fields during water-saving, not only reducing the pollution of rivers, lakes, and seas caused by pesticides and fertilizers dissolved in water, but also It is of great significance to maintain stable grain production in dry areas.

Rapid Test Kit

Rapid test kits are designed for use where a preliminary screening test result is required and are especially useful in resource-limited settings.
• High quality
• Quick (10 minutes to 2 hours) and easy to perform .
• Tests based on agglutination, immuno-chromatographic, immuno-dot, and/or immuno-filtration techniques.
• Are suitable for individual or a limited number of samples, and require little or no additional equipment, which make them more economical than ELISAs in fully equipped laboratories.
• Possibility to store at room temperature for an extended period of time.

• Same-day results provide timely treatment possibility.



[Test Principle]

Urobilinogen:Urobilinogen with diazonium salt produce red violet dyes in strong acid medium.

Bilirubin:The direct bilirubin with dichlorobenzene diazonium produce azo dyes in acid medium.

Ketone:The acetoacetic acid and sodium nitroprusside cause reaction in alkaline medium,which produces red violet compound.

Blood:Hemoglobin acts as peroxidase. It can cause peroxidase release neo-ecotypes oxide (O).(O) oxidizes the indicator and make the color change subsequently.

Protein:It is based on a specific pH indicator attracted by cation on protein molecule,the indicator further ionized and make the color change.This phenomenon is called protein-error-of -indicator principle.

Nitrite:Nitrite and aromatic amine are diazotized to form a diazonium compound.The diazonium compound reacts with tetrahydrobenzo(h)quinolin 3-phenol produce the red azo dye.

Leukocyte:Pyrrole amino acid ester produce free phenol under the hydrolysis of esterase in neutrophile granulocyte,the free phenol couple with phenyl diazonium salt produce purple azo dyes.

Glucose:The glucose oxidized by glucose oxidase catalyzes the formation of glucuronic acid and peroxide hydrogen.Peroxide hydrogen releases neo-ecotypes oxide(O)under the function of peroxidase.(O)oxidizes tetramethyl benzidine, which make the color change.

Specific Gravity:Methyl vinyl ether and maleic acid copolymer is weak acid (-COOH) exchanger,the M+ cation (the major is Na+) in urine reacts with the exchanger and release hydrogen ion,hydrogen ion reacts with indicator produce color change.

pH:The method of pH indicator is applied.

Ascorbic Acid:Ascorbic acid deoxidizes the 2.6-dichlorphenolindophenol dye into colorless in alkaline medium.

Microalbumin:Sulfone phthalein dye has high sensitivity to microalbumin by the method of protein error.

Creatinine:Creatinine with 3,5-Dinitrobenoic acid produce violet compound in alkaline medium.

Calcium:Calcium ion reacts with methyl bromothymol blue produce color change in alkaline medium.
