Method for improving shoot cutting rooting rate of Corylus heterophylla Fisch. and C. avellana L. in arid region

Abstract

The invention relates to a method for improving the shoot cutting rooting rate of Corylus heterophylla Fisch. and C. avellana L. in an arid region. According to the method, based on the special climatic features of the arid region, a shading net is erected on the upper portion of the outside of a simple greenhouse, facilities such as a micro-fog humidification system and a cutting bed installation micro-spraying device are installed in the greenhouse, the environmental conditions of light, temperature and humidity needed by the shoot cutting seedlings of the Corylus heterophylla Fisch. and C. avellana L. are regulated and controlled, and therefore the purpose of increasing the rooting rate can be achieved. By means of the method, the shoot cutting effect of the Corylus heterophylla Fisch. and C. avellana L. planted under environmental conditions of the arid region is greatly improved, the rooting rate is improved to 76.35% in the year of 2013 from 25.73% in the year of 2012, seedling growing cost is reduced by 50% or so, the major breakthrough of rapidly propagating the improved variety of seedlings of the Corylus heterophylla Fisch. and C. avellana L. in the arid region is achieved, a seedling growing method high in propagating efficiency and low in cost is provided for rapidly propagating improved variety of sound seedlings, and the improved variety of sound seedlings are rapidly provided for large-scale promotion and forestation of the Corylus heterophylla Fisch. and C. avellana L.

Description

technical field [0001] The invention relates to a method for improving the rooting effect of Pingou hybrid hazel twig cuttings in arid areas. Background technique [0002] Pingou hybrid hazel ( Corylus heterophylla Fisch. x C. avellana L. ) for my country's flat hazel ( Corylus heterophylla Fisch. ) and filbert ( C. avellana L. ) is an excellent variety bred by distant hybridization between species. It has the dual advantages of strong cold resistance and adaptability of flat hazelnut and large fruit, high yield and high kernel yield of European hazelnut. It can bear fruit in the second year after planting. The yield of nuts per mu is more than 200 kg, and the income is more than 8,000 yuan per mu according to the market price. [0003] In 2001, the Xinjiang Academy of Forestry introduced the Pingou hybrid hazel to carry out the selection of fine varieties and the demonstration and promotion of high-yield cultivation techniques in suitable areas in Xinjiang. In 2010, ...

Problems solved by technology

[0004] In the process of promoting and expanding the planting area of ​​fine varieties of Pingou hybrid hazel in Xinjiang, the supply of fine seedlings is in short supply and the price is high. Long, low technical reproduction coefficient, poor uniformity of seedlings, unable to meet the current demand for high-quality seedlings in large-scale planting in Xinjiang

In order to cultivate as soon as possible the number of fine varieties of commercial seedlings needed for the rapid development of Xinjiang, the twig cutting experiment of Pingou hybrid hazel was carried out in 2011, and it was initially successful. In 2012, a large area of ​​promotion and application was carried out, but the rooting rate was not high. Renyi, in 2013, aimed at the existing technical problems, carried out technical research and achieved satisfactory results, and summed up a set of effective ways to improve the seedlings of fine varieties of Pingou hybrid hazel twigs in simple plastic greenhouses in arid areas. Rapid breeding of strong seedlings of fine varieties in Xinjiang has opened up a seedling raising technology with high reproductive efficiency and low cost
