标题(英语)

Method for forcing germination epicormic branch cuttage of Catalpa bungei root segment


摘要(英语)

The invention discloses a method for Catalpa bungei root segment germination accelerating shoot cutting, which is characterized in that, in the November of each year, root segment from Catalpa bungei is dug out; the coarseness of the root segment ranges from 0.5cm to 3.0cm; the clipping length ranges from 5cm to 20cm; from the middle and last ten days of January to the beginning of February, the root segment is put in the germination accelerating trench of a greenhouse for accelerating germination; when the bud seedling tillering from the Catalpa bungei root segment has three to five true leaves and achieves semi lignification, cutting treatment is performed. The method has the advantages that, shoot cutting are formed by the root segment with bud, so the survival rate is relatively high; the average survival rate is 93.2%; the shoot cutting are treated by fast dipping in the solution having the concentration of the mixture of ethyl acetic acid and acetic acid mixed according to the ratio of 1:2 for 500mg/L, and the rooting rate and the root number of the cuttings are greatly improved; the shoot cutting performed in the greenhouse with spraying condition has better effect; the mixture of cattle manure and saw dust mixed according to the proportion of 1:1 can be used as substrate; the cutting seedlings can be cut and transplanted in the same year; the average seedling height can achieve 170cm; the average ground diameter is 2.8cm; the rate of emergence and survival rate are high; the rapid propagation requirements to breed seedlings and produce strong seedlings in the same year are satisfied.
