Study On Softwood Cutting Techniques Of Hybrid Hazels?Corylus Heterophylla Fisch. ×Corylus Avellana L.?

Corylus heterophylla Fisch.×Corylus avellana L. was hybridization and breeding from Corylus heterophylla Fisch and Corylus avellana L good varieties(or lines), because of its has high fruit large, kernel, cold-resistant, suitable range, etc, In the north slope of tianshan mountain as ecological economic tree species have wide development space. At present in the production of flat the hybrid hazel twig cuttings seedling is often adopted,although the rooting rate of more than 80%,but exist some problems such as bud fall off in rooting period,the root of poor quality,The lack of new shoots of cuttings,difficult to meet ping the hybrid hazel large area to promote demand for nursery stock. Therefore, this research choose 2010 year varieties in xinjiang autonomous region authorized, form the most good three flat the hybrid varieties of hazel(New hazel one, New hazel two, New hazel three) as research object, In order to solve the cutting seedlings rooting buds falls off, the root of poor quality and lack of new shoots as the starting point, by controlled trials testing, matrix, foliar fertilizer formulation, kind and concentration of exogenous hormones, cuttings specifications on the hybrid hazel cutting seedling root traits and the influence of the new shoots growth traits, In order to smooth the hybrid hazel seedling for the efficient production of empirical basis and technical solutions, On the large extension of hybrid hazel has important practical significance. The main research results are as follows: The length of cuttings and hormone treatment time is flat the hybrid hazel cuttings rooting rate and germination rate of the two biggest factors. Cutting length is 10 cm, hormone treatment time choosing 10 s bud rate and rooting rate of cuttings can reach maximum.Spraying on the leaf fertilizer 2 g/L of urea + 0.375 g/L amino acids to guarantee the quality of the flat the hybrid hazel cuttings root cases, the cuttings leaf SPAD value, growing of new shoots and buds germination promoting the most obvious. Spraying 2 g/L of urea + 1.5 g/L of potassium dihydrogen phosphate fertilizer processing rooting effect is poorer, not recommended.IAA and GA3 on the formation of the hybrid hazel cuttings root and bud germination has a promoting effect, the formation of ABA on cuttings root and bud germination inhibition. New hazel one and New hazel three are at 2000 mg/L IBA + NAA treatment effect is best, rooting rate reached 84.76% and 69.52% respectively, the germination rate was 45.71% and 40.00%, respectively, new hazel two with IBA + NAA 1500 mg/L effect is best, rooting rate and germination rate of 44.76% and 23.81%Comprehensive effect of various factors on the flat the hybrid hazel cutting, the influence of xinjiang flat the hybrid hazel twig cutting seedlings recommended technical measures as: choose peat soil matrix, 10 cm in length, cutting the foliar fertilizer formula 2 g/L of urea + 0.375 g/L amino acids, exogenous hormones to choose 2000 mg/L IBA + NAA, the processing time for 10 s...
