Study On The Quality Standard And Production Techlogical Schedul In Propogation The Cuttings On Photinia Frasery By Cuttings On Trival In Hefei

Photinia frasery is a genus Photinia cultivars bred, named for its bright red leaves. Red Robin currently on the market there, red lips, Rubens, fire red and other varieties, were from New Zealand, the United States, Japan, the Netherlands and other countries introduced. Characterized by leaves of long duration, germination and strong, very resistant trim, suitable for red hedges. One Red Robin compact plant type, reproductive ability, rapid growth, and so dominant in many species show has become a 'redPhotinia mainstream varieties. However, the lack of uniform standards, propagation technique is not standardized, resulting in seedling market Photinia Chupu seedling quality varies greatly. In this study, Hefei, Anhui, seedlings should flower Association, Resources in Anhui garden nursery base in the company cutting propagation of Red Robin (Photinia frasery) were used to systematically study the Photinia Seedling production technology standardization, detailed When recording the production process, for improving survival and quality Plug cuttings technical processing point of doing a comparison test. And by the cuttings, based on established Photinia Plug cuttings quality standards and production technology company rules. The main findings are as follows:1. Scion Resources Landscape Garden Photinia mother plants on the scion, carbendazim 1000 times with sterilized after cutting cutting media test results, the use of perlite + peat + vermiculite used with good effect. The results showed that treatment in the trial to perlite + peat + vermiculite (1:1:1) formulas better substrate.2. Cuttings for rooting powder on the concentration of species with the choice of test results, the IBA in the rooting rate of up to 76.0%, with the concentration, the first root is significantly increased, then decreased. With the trial of the 11 kinds of rooting powder to IBA in the concentration of 200 mg ? L-1 soaked 10min for the best rooting treatment, can get a higher rooting rate and root number.3. Research on the choice of cutting test, obtained using a half lignification Current year branches as cuttings of Photinia cuttings and root survival rate more favorable quality.4. Placed on the cuttings were drawn in the bottom of the hollow plug placed on a shelf, because the effect of air repair root, root quality will be better. In addition to the for light mesh bag seedling test, found that light mesh bag seedling root system quality is better than Seedling.5. Plug in the cuttings carried out in fertilizer experiments, found that application of slow-release fertilizer APEX root cuttings quality and shoot dry weight than the control group had a distinct advantage. Foliar fertilizer in the experiment, fertilization group than the control group had a significant advantage. 6. Good growth after the transplanting of rooted by hardening into peat: vermiculite: perlite = 3:1:1 in the matrix, the survival rate of 95%.7. Seedling survival of the cuttings with different concentrations of NAA. The observation compared with the control group (without NAA) of the root system to be more lateral roots. The test, NAA concentration is 30mg ? L-1 the best effect.8. Detailed record of production and test data, a comprehensive analysis concluded Resources Landscape Company, Zhejiang, China Zhejiang Yongyue U.S. gardening and the company's production experience, to develop a landscape company, China Resources Photinia Seedling quality standards and production of technical specification.
