Peanuts are often badly sown before emergence after sowing, and the severe rotting rate is as high as 20%, resulting in varying degrees of deficient seedlings. Rotten species: poor seed quality or improper storage, storage period is too long; low-lying terrain, soil viscosity, poor texture, high soil moisture content, long seed emergence time; soil preparation is not true, affecting the seed of water absorption, weak seedlings; The seeds are not selected, the size is uneven, the seeding is not fine or varies in depth, resulting in uneven seedlings or lack of seedlings and ridges; the continuous cropping does not collapse, the seedling stage disease is serious, resulting in lack of seedlings and ridges; the application of organic fertilizer is not fully decomposed Or fertilizer concentration is too high, resulting in fertilizer damage, affecting the emergence; long duration of low temperature, causing germination and seedling slow and bad species. Control methods: 1, fine selection. The new peanut seeds were selected and harvested, and the seeds were harvested in proper time and dried in time so as to be scientifically stored. Before planting, seeds are sun-dried, and the metabolism of peanuts is added to increase the seed penetration and increase the water absorption capacity of seeds. The shells were peeled 1-3 days before sowing, and the seeds that had not been damaged or germinated were selected for sowing. 2, drug seed dressing. Use seed dressing with 0.1% of 50% thiophanate-methyl or 50% carbendazim WP to prevent seedling disease. 50% phoxim-emulsifiable oil with a seed weight of 0.2% can also be used to control underground pests and bird and rat damage. 3, fine sowing. Seed with a depth of 4-6 cm, avoid seed and fertilizer contact. The use of plastic film covering cultivation, the ground temperature can be increased 2-3 °C, after sowing seeds germination, seedlings quickly, can reduce the incidence. Varicella Vaccine(Live)
1.Good safety of gelatin-free.The first lyophilized Varicella Vaccine, free of animal gelatin, was invented and produced in China, which can significantly decrease the ratio of anaphylaxis incidence .
2.Long validity period for good stability. The first approved varicella vaccine with 36 months of validity period in the world. The application of BH-2 stabilizer with own IP rights (Chinese patent granted No.: ZL200910138411.6, International patent application No.: PCT/CN2009/001405) greatly enhances the stability of the product and ensures the validity period for 36 months under the storage condition.
3.Better protection with high titer and immune performance. It`s documented that compared with the varicella vaccine of low titer, high titer vaccine can reduce breakthrough cases by nearly 75% in vaccination. Among all released batches of Varicella Vaccine from BCHT, the titer is not less than 10000 PFU/dose tested by National Institutes for Food and Drug Control.
