Control the side vines, strong vines. Remove all side vines, leaving only the main vines. One male flower is kept every 3 to 4 knots, and the rest of the male flowers and tendrils are removed in time. The male flowers are best picked from the flower buds, and the tendrils are exposed and removed. Scientific management. In the early stage of growth of loofah, due to less male flowers or low temperature, it often has little fruit, and the fruit is small and poor. Therefore, it is necessary to apply a fruit handle to the targeted medicament, which can significantly increase the fruit setting rate. Before flowering, in the young fruit stage and in the expansion stage, each time the squash is applied, it can activate the plant ecological growth positive energy, broaden the plant conduit path, enhance the water absorption and fertilizer absorption of the plant, increase the fruit yield and quality, reduce the fruit drop rate, and reduce The incidence of cracked fruit, stiff fruit, and deformed fruit. Remove the old leaves. All the old leaves and diseased leaves of the leaf age of more than 2 months with loss of function were removed to facilitate the growth of ventilated light and apex stems. After the removal, the new high-fat film is sprayed 600 times night, and a polymer protective film that is invisible to the naked eye can be automatically formed to optimize the water absorption, air permeability and light transmission quality of the plant. Blocking pests and smuggling signals and weakening the media to resist and defend against natural environmental disasters. Disclaimer: Some articles on this website are transferred from the Internet.

1. Introduction Nucleic Acid Extraction Reagent Kit,Nucleic Acid Extraction Kit,Covid-19 Nucleic Acid Extraction Reagents,Nucleic Acid Test Kits Jilin Sinoscience Technology Co. LTD , https://www.jlgkscience.com
The total viral nucleic acid extraction kit is suitable for extracting total viral nucleic acid from serum, plasma, tissue homogenate and other samples. The kit is based on silica column purification technology, which eliminates the need for toxic phenol-chloroform extraction and time-consuming alcohol precipitation. This product has successfully extracted nucleic acids from hepatitis B A/C, hepatitis C, and norovirus standard. The obtained DNA/RNA can be directly used in a series of downstream experiments such as PCR, RT-PCR, and LAMP.
Notice:
1. The carrier RNA solid must be dissolved in Nuclease Free Water to 1µg/µl before use, and vortex to dissolve. Store in aliquots at -70°C. If you need to store it at -20℃ for a long time, please repackage it according to the number of times of use.
2. Dissolve Proteinase K (20mg/ml): Add Proteinase Dissolve Buffer to dissolve Proteinase K to a final concentration of 20mg/ml. Proteinase K dry powder can be stored at 2-8°C for one year, but dissolved Proteinase K must be stored in aliquots at -20°C. Repeated freezing and thawing of Proteinase K can affect its activity.
3. Buffer VHB must be diluted with 14 ml absolute ethanol before use and stored at room temperature.
4. Buffer RW2 must be diluted with 80 ml of absolute ethanol before use and stored at room temperature.
3. Shelf life
Except for Proteinase K and Carrier RNA, other components of this product can be stored at room temperature (15-25°C) for 12 months, and should be stored at 2-8°C for long-term storage. Proteinase K and Carrier RNA dry powder are transported at room temperature. Please store at -20°C after receiving the test product, and store at -20°C after dissolving.
