Method for using fermentation warming bed to conduct hardwood cutting of carya illinoensis

Abstract

The invention discloses a method for using a fermentation warming bed to conduct hardwood cutting of carya illinoensis. After a carya illinoensis nursery land is subjected to bud grafting in summer, one-year-old seedling stock twig of stumping in a dormant season is adopted as a material, slots are dug in an cutting heat preservation shed, the slots are filled with a mixed material with the ratio of sheep manure containing 'baiyibao' original EM to soybean straw being 2:1, and the distance from the filled material to the bed surface is 5 cm, then the bed is filled with a mixed substrate with ratio of perlite, to turfy soil to loess being 1:1:1 till the substrate and the bed surface are flush. The fermentation bed is capable of effectively generating heat and forming a temperature difference of 13.19 DEG C between the temperature of the position close to cutting base and the cutting bed. One-year-old carya illinoensis seedling twigs of which the 5cm roots are soaked in an NAA 900 ppm solution for 4 hours are capable of effectively taking root on the fermentation bed, the root taking rates are 81.11% separately, and the average value is obviously higher than the result of 10.00% of a control group. The fermentation bed is a good technology which can be adopted to generate the temperature difference and plant cutting, and the technology has the advantages of saving energy and protecting environment, saving labor and saving cost.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and relates to a method for cutting hard branches of hickory with thin shells by using a fermentation intensifying bed. Background technique [0002] Hard branch cutting is a common technique for asexual reproduction of many plants. At present, there are many related research reports on the type and concentration of hormones, age and location of cuttings, cutting facilities and environmental control on the tree species of hickory, such as Chang Jun et al. The emergence rate of cutting seedlings raised by cuttings of hickory nuts is 67.5%; Geng Guomin et al. reported that the rooting rate of the best treatment for hardwood cuttings is only 4%; research by Huang Youjun and others found that IBA is the most effective for rooting hardwood cuttings of hickory hickory . Temperature difference is an important factor affecting the survival of cuttings, which is reflected in the difference betw...
