Promote Germination Technology of CunninghamialanceolataTuttingTrchard by Tense Tlanting and Tending TurseryStock

In order to promote the sprout yield of Cunninghamialanceolataclones‘Liu229’andXishan‘9122’in the two clonal panicle garden，theL9 (34) orthogonal test was used to screen out the high yield combinations that could increase the yield of sprout strips from the three factors of bar pressure, planting depth and planting spacing, and the effects of the three factors on the yield of sprout strip were analyzed.. The results showed that the highest yield combination was that the stalk and the ground were 20 ~ 30 degrees, the planting depth was 1 to 2 cm, and the spacing between planting was 30cm×30cm. Under this combination,‘Liu229’can produce more qualified sprouts than‘Xishan 9122’,the effective germination of the Cunninghamialanceolata(length of 6cm and no obvious crown deviation) can reach 45axis per tree or more, the effective sprouting yield per hectare can reach 3.9 million or more, which is suitable for increasing the yield of the sprout of the Cunninghamialanceolata cutting orchard.
