Sugarcane selection and storage

First, the choice of sugarcane

Japanese sugarcane belongs to fruit cane, different from southern sugar cane (industrial sugarcane). It can be preserved in whole stems. The old buds in the base are more buds than the shoots, but they are not as good as shoots (because of the concentration of plant hormones. At the tip). Sugarcane species should be dug directly in the sugarcane field before and after the National Day in October. At this time, the cane stalks are stout and the sugarcane buds are substantial. The biggest advantage is that the sugarcane buds are all protected by leaf sheaths, and the tops and bottoms are transported and transported on the way. Not easily affected by freezing, sugarcane buds are not easy to damage, so the production of more than "the main purchase in the fall, supplemented by spring purchase."

Second, the harvest of sugarcane

Sugar cane used for whole-stem seed retention, often with a root plan before the frost, so as not to increase the wound. According to the production test: All the sugarcane species without roots are extremely unfavorable for the winter in the storage pits, and the spring and spring are easy to form seedlings and weak seedlings. Sugarcane must have leaf sheaths to protect sugarcane sprouts during transport and storage. After harvesting, temporarily put it in a cool place, and store some water and hot air before storing it. In addition to retaining the "canetail", the cane shoots can be cut with 3 knives of shoots with a sharp knife. After the incision is painted, the sand in the pit is preserved. The plots that are to be reserved for sugarcane species are generally not used for natural growth except for measures such as removing sugar and adding sugar. In order to improve the quality of sugarcane, attention should be paid in the management of the middle and later stages to the removal of sheath and the addition of nitrogen to the leaves. Last year, we conducted the following test on the whole stem left in the sugarcane field. The introducer may wish to try it, "cut the cane head one week in advance, and the next year will sprout like a cow." The full-stem sugarcane planted after going through the storage pit was full of sprouts and the emergence rate was as high as 100%.

Third, the storage of sugarcane

The preserved sugarcane stalks are characterized by bogey, bogey, bogey, bogey, and rot. In the provinces south of the Yangtze River, it is only necessary to store it in the interior of an auxiliary wet sand to safely pass winter. In the northern winter, the winter temperature suddenly drops and ice drops drip. The sugarcane must be stored in winter. There are two ways.

(a) cellar storage

Choose a deep layer of soil and shelter from the well-drained slopes. The depth of the cellar is more than 1 meter (depending on the height of the cane stems, the depth of the cellar is selected). 10 cane stalks are bundled one by one, and then vertically placed into the pit. In addition to the vertical storage cellar cane, but also can choose to use the head and tail staggered horizontal row pit, the bottom of the pit in the "well" shape placed a good brick, so that the pit shellyard empty yards. Regardless of the vertical or horizontal storage pits, a plastic pipe with a diameter of 8-10 cm is usually placed every 1 m (with a hygrometer inside) for observation of temperature and ventilation. In case of pitting too dry, the roots of the cane must first be soaked with a 2% lime solution and then drained. At the beginning of the cellar surface, only some sugarcane leaves or grasshoppers must be covered. After freezing, the soil should be covered 30-50 cm thick. After the cover soil, the cellar top should be a turtle shape or ridge shape, and the ventilation holes should be closed. Snow should be promptly removed after the snow to prevent the snow from seeping into the cellar. After the frost is finished the following year, cellar germination should be started as soon as possible.

(b) Ditch storage

With the whole stem or sugarcane shoots can also be ditch storage, the depth of the ditch is equal to the height of the sugarcane stem or cane tip, the bottom requires smooth soft, cane type tilt discharge. Ditch cover and earth cover can refer to the above cellar storage method. Regardless of cellar storage or furrow storage, the temperature is 6 degrees for the most suitable, requirements not less than 4 degrees, 4 degrees below the vulnerability to freeze damage, high but 8 degrees, more than 8 degrees easy to hurt heat, 10 degrees of origin of aerial rooting. The sugarcane plant is very sweet, and it is easy to provoke ants, cockroaches, and mice. The best winter storage is to spread some green grass in the ditch, in the bottom of the pit and all around, or spray it with dichlorvos or ammonium phosphate after capping the cane stem. . The spring of the next year will turn for the better. We must reduce the earth cover in order to facilitate ventilation and warming.

  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 efficacy. 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.
