Method for cultivating zelkova schneideriana seedlings through cuttage

Abstract

The invention discloses a method for cultivating zelkova schneideriana seedlings through cuttage, and relates to the technical field of zelkova schneideriana seedling cultivating and planting management. The method is characterized by comprising the following steps that during the cuttage period, cutting slips are selected, wherein branch sections located on the lower middle portions of branches growing for one to two years are selected as the cutting slips, and the thicknesses of the branch sections rang from 0.7 cm to 1 cm, and according to the cut length, the branches which respectively have three or more knots are selected; the mixture of yellow subsoil and sand serves as a cuttage medium, wherein the yellow subsoil is red earth where limestone grows, the pH value of the yellow subsoil ranges from four to six, and the mixture is smashed and screened; cuttage is carried out, and the cutting slings are watered thoroughly, wherein the bundled cutting slips are immersed through ABT 6 rooting powder with the immersed depth of 2 cm for five hours, the concentration of the ABT 6 rooting powder ranges from 200 mg / L to 300 mg / L, the cutting slings are inserted into a nutrition bag after being immersed, the inserting depth is one third of the length of the cutting slings; management is carried out, wherein the cuttage seedlings with the same specification are cultivated, the inserted seedlings are watered one time every other month and are regularly sprayed by carbendazim solutions with the concentration of 0.125 percent . By means of the method, the seedling cultivating period is short, the rooting rate is high, root systems are developed well, the survival rate is high, managing is convenient, lands are saved, and increase of the economic benefits of zelkova schneideriana seedling is facilitated.

Description

technical field [0001] The invention relates to the technical field of planting and management of beech seedlings, and relates to a method for growing beech seedlings by cutting. Background technique [0002] Beech is a precious hard broad-leaved timber tree species in my country and an important export timber. Excellent material, strong wind resistance, smoke and dust resistance and air purification, resistance to drought and barrenness and short-term flooding (1 to 2 months), natural renewal is relatively easy. The resources of beech trees are few, the trees are old and strong, and the years are sparse, so it is difficult to collect seeds; the germination rate of seeds is about 20% to 40%. For this reason, zelkova in the prior art carries out sand bed cutting seedling cultivation, and the seedling cultivation period is long, and rooting rate is low, and root system is underdeveloped, and survival rate is low, and management is inconvenient, and takes larger land.
