Seeding and seedling: After the whole planting, the soil surface is sprayed with 600-800 times of new high-fat film, which can protect the water-proof evaporation, sun-proof and drought-resistant, heat-preserving and anti-freezing, anti-soil layering, suffocation and isolation of pests and diseases, and increase the emergence rate. Timely transplanting, rational close planting: In order to give full play to the potential of rapeseed production, it is generally carried out by manual drawing, with a row spacing of 30 cm, a plant spacing of 20 cm and a depth of 3 cm. Spraying a new high-fat film in time after transplanting can effectively prevent the ground water from evaporating. The seedlings are not transpiration, isolate pests and diseases, shorten the slow seedling period, quickly adapt to the new environment, and grow healthily. For the rapeseed with long-term fertility, a new high-fat film + foliar fertilizer can be sprayed to inhibit the main shoots from becoming mad, improve the resistance to stress, and reduce the occurrence of freezing damage and pests. Anti-disease and pest control, mixed drug and fertilizer: During the growth of rapeseed, the main pests and diseases are aphids, downy mildew and sclerotinia. For the aphids, the bio-pesticide insects can be used for prevention and control of 1:1300 times, for downy mildew and sclerotinia You can use 12.5% ​​synergistic carbendazim 1:500 times, and add new high-fat film and Zhuangsuiling. This can not only prevent disease and control insects, but also strengthen the physiological functions of rapeseed, improve pollination, insemination, grouting quality and increase 1000-grain weight.

Magnetic Bead Acid Nucleic Extraction Kit

In order to implement the requirements for the prevention and control of the new coronavirus pneumonia epidemic, all parts of the country are actively cooperating in the normalization of epidemic prevention and control. Each city has arranged multiple nucleic acid testing sampling points, and requires a negative nucleic acid test result within a few days. Public places are accessible, and the importance of nucleic acid testing for epidemic prevention and control is self-evident.
As of now, there are 13,000 medical and health institutions in the country that can carry out nucleic acid testing, and 153,000 professional and technical personnel are engaged in nucleic acid testing technology. The nucleic acid testing capacity has reached 57 million tubes per day. In order to help the prevention and control of the new crown epidemic, Yisheng Biology quickly launched the nucleic acid extraction reagent + 96-channel automatic nucleic acid extraction instrument. It only takes about 10 minutes to extract 96 nucleic acid samples at one time, and extract nucleic acid in a faster and more accurate way. Work becomes more efficient.
Magnetic Bead Swab Sample Viral DNA/RNA Extraction Kit can be used to isolate and purify high-quality viral DNA/RNA from various swabs and virus culture supernatants. By using magnetic beads with unique separation function and carefully optimized buffer system to efficiently capture the released nucleic acid, the extracted nucleic acid has high yield and good quality, which is suitable for various downstream application experiments, such as RT-qPCR, qPCR and other experiments.
