Guang Yulan High Pressure Breeding

Breeding by high pressure method has received better results.

1, the need to use items culture soil (by volume ratio, the ratio of garden soil, moss and old ash is 1:0.5:1, mix well with water, hand into a group, slightly watermark, but not for the degree of drip); Branch shears; grafting knife; plastic film (length 30 cm, width 25 cm); small brown rope and so on.

2, the mother tree choose to choose tree height 160-200 cm (easy to operate), grow robust and dense branches of adult trees.

3, the pressure layer time from the early April to early May the most appropriate. The sap flowed vigorously at this time, and it was easy to peel and it was conducive to wound healing.

4. Batten method First, select a 2-3-year-grown shoot that grows densely at the denser branch of the tree crown, about 0.8-1 cm thick, girdling 10-15 cm from the base of the shoot, width 2-3 cm, and shave. Form a layer to prevent the skin from healing again. The bandaging is carried out step by step, first in the lower part of the wound 8-10 centimeters, the plastic film is tied tight with a string, then rolled up into a cylindrical shape, and then filled with a good culture soil, always fill the upper end of the peeling 6 As far as -8 centimeters, squeeze it out of the membrane by hand, make the soil group into a braided shape, and finally tie it tightly, and bundle it properly in the periphery of the soil mass.

5, under the tree management layer can be rooted after half a month, where the survival of the seedlings can see the root outside the film. From June to September, the trees were transplanted with soil to make water. After paying attention to drought irrigation, and chasing thin organic fertilizers at the same time, it can be planted in late October.
