Practice has proved that timely pouring of frozen water, can stabilize the temperature, can prevent the cold flow on the wheat seedlings, protect the wheat seedlings safe winter. Preventing drought in early spring is conducive to cultivating strong seedlings in the spring; crushing rubbish, solid soil is beneficial to the growth of wheat seedlings. For sandy lands and loamy soils, it is particularly necessary to use frozen water. Low-lying lands, clay fields, wet grounds, and late-seeding wheat fields are not suitable for pouring frozen water. In late-sowing wheat fields, frozen water is still needed if necessary, and can be flexibly controlled according to the specific circumstances. In principle, water should not be distributed in order to avoid silt seedlings, affecting growth and causing freezing damage. The time for pouring frozen water should be at the time of “freezing in the night”.

Genetic Analyzer For STR

Genetic Analyzer For STR (Short Tandem Repeat)

Using DNA identification technology helps crime-solving and criminal activities combat is a worldwide common consensus. It applies modern medical high-tech technology effectively in the criminal investigation. However, in the detection of many criminal cases, when a male criminal suspect leaves physical evidence at a crime scene, the DNA information data of the sample needs to be collected into the anti-crime DNA database which use for Genetic Analyzer For STR,Analytical Forensic Instrument,Genetic Analysis Test for STR.
