To plant the winter jujube in the spring

1, late spring and late planting: winter jujube is a thermophilic variety, the average temperature began to germinate at 14 °C. Thin winter jujube, if planted in early spring, easy to dry and dehydration, affect the survival rate. Through experiments, the survival rate in late spring planting was increased by about 11% compared with early spring planting, and the pseudo-death rate was decreased by about 7%.

2. Excavate large pits and apply sufficient fertilizer: dig large holes before planting winter jujube trees, usually 1 meter square, 80 centimeters deep, mix the topsoil with base fertilizer and fill it in the bottom, and apply 50 kg of fertilizer and diammonium phosphate per plant. Kg, and water compaction.

3, reduce the tree plate, avoid salt pressure alkali: according to the "water to the lower flow, salt go to heights," the operation of water and salt law, when planting trees under the trimming of 3 square meters below the ground 15 cm, To accumulate rain, avoid salt and alkali.

4. Covering the film: After the seedlings are planted, cover the ground with a 1 m2 mulch. The covered ground is slightly lower in the middle and slightly higher in the surrounding, and it is in a pot-like shape, with soil around the mulch and the trees. Spring mulching can increase soil temperature, maintain soil moisture, prevent salt from moving upwards, promote early root growth, and greatly reduce seedlings. In summer, the plastic film should be peeled off in time to prevent excessive ground temperature and inhibit root growth.

5, tree plate cover: After peeling off the plastic film, we can use wheat straw to cover the tree plate, about 20 centimeters thick, and then thicken 10 centimeters in the second year, which can save the cultivating weeding, and can play a drought-resistant, alkali, Insulation moisture, increase humus, improve the role of soil.

Bulk of varicella vaccine,semi-Finished Products.It has good safety with low ratio in adverse reaction. And it has been exported to Bangladesh. 

In 2008, BCHT successfully launched its product Varicella Vaccine, Live in China.
