2, the time period of spraying trace element fertilizer must be based on vegetables and different trace element fertilizer species may be set, generally in order to spray before flowering is appropriate.
3. The amount of 40-75 kg of fertilization solution should be sufficient to wet the stems and leaves of vegetables.
4, the number of leaf off the general use of fertilizer less, so it is difficult to meet all the needs of the growth and development process. According to the length of the growing period of the vegetables, it is advisable to spray 2~4 times.
5, time should be selected to spray cloudy afternoon or sunny afternoon, can extend the retention time of fertilizer solution on the leaves of vegetables, help to improve the spraying effect.
6, mixed spray off trace element fertilizer mixed spraying, or mixed with other fertilizers and pesticides, can save the process, play a "multi-effect" role. However, all kinds of trace element fertilizers are not allowed to be mixed with alkaline fertilizers such as grass ash and lime, zinc fertilizers cannot be mixed with superphosphate, and copper fertilizers must not be mixed with potassium dihydrogen phosphate solution.
1.Good safety of gelatin-free.The first lyophilized Varicella Vaccine, containing no gelatin from animals, invented and produced in China. Getting rid of gelatin from varicella vaccine can significantly decrease the ratio of anaphylaxis incidence .
2.Long validity period by good stability. The first approved varicella vaccine with 36 months of validity period in the world. Adopting 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 eff
icacy. It`s documented that compared with the varicella vaccine of low titer, high titer vaccine can reduce breakthrough cases by nearly 75% in vaccination. Of all released batches of Varicella Vaccine from BCHT, the titers are not less than 10000 PFU/dose tested by National Institutes for Food and Drug Control.
