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

A kind ofly improve the method that the flat Europe of arid biogeographic zone hybrid hazel epicormic branch cuttage is taken root

Technical field

The present invention relates to a kind of method that improves the flat Europe of arid biogeographic zone hybrid hazel epicormic branch cuttage rooting efficiency.

Background technology

Flat Europe hybrid hazel ( corylus heterophylla Fisch.x C.avellana L.) be the flat hazel of China ( corylus heterophylla Fisch.) and filbert ( c. avellana L.) improved seeds that select of interspecific hybridization, the fruit with the cold-resistant strong adaptability of flat hazel and filbert is large, high yield, two-fold advantage that kernel percent is high, and the 2nd year can be solid in field planting, abound with phase per mu yield nut more than 200 kilograms, take in above by 8000 yuan/mu of market prices.

Calendar year 2001, Xinjiang forest-science academy introduces flat Europe hybridization hazel and has carried out demonstration and the popularization of improved seeds screening and high-yield cultivation technique at Xinjiang Production Zones Suitable, 2010 by 4 of high quality tree species validation board of autonomous region authorization kinds, be respectively " new hazel No. 1 " (84-254), " new hazel No. 2 " (82-11), " new hazel No. 3 " (84-310), " new hazel No. 4 " (82-15) and in 20 Yu Ge counties and cities such as mountain region counties and townships such as Ili River Valley, Northern Slope of Tianshan Mountains, Altay Mountains, South Sinkiang Baicheng, Wensus carried out introducing and planting.The advantages such as cold-resistant, solid morning that flat Europe hybrid hazel shows in Xinjiang, yielding ability is strong, management is simple, development potentiality is huge.End 2013 cultivating and growing areas and reached more than 30,000 mu, now become the new highlight seeds of Xinjiang characteristic industry of planting forest or fruit tress sustainable development.

Ping Europe, Xinjiang hybrid hazel improved seeds are promoted in the process that expands cultivated area, supply falls short of demand and situation on the high side breeding nursery stock, although traditional green branch propagation by layering method has been obtained to mature technology, because its numerous seedling cost is high, cultivation period long, technology reproduction coefficient is low, nursery stock regularity is not good enough, cannot meet the demand of current Xinjiang establishing in large scale to high quality seedling.For cultivating as early as possible the quantity of the fast-developing required improved seeds commodity nursery stock in Xinjiang, within 2011, start to carry out the epicormic branch cuttage test of flat Europe hybrid hazel, tentatively succeed, within 2012, having carried out larger area applies, but rooting rate is unsatisfactory, 2013 for the technical problem existing, carry out research of technique, obtain gratifying effect, and sum up the effective way of the flat Europe of the simple and easy plastic tunnel of a set of raising arid biogeographic zone hybrid hazel epicormic branch cuttage breed good strains nursery stock, for Xinjiang fast breeding breeding, to have opened up a reproductive efficiency strong sprout high, the seedling growing process that cost is low.The present invention can be flat Europe, Xinjiang hybrid hazel spread afforestation, Quick for breeding strong sprout.

Summary of the invention

The object of the invention is to, a kind of method that the flat Europe of arid biogeographic zone hybrid hazel epicormic branch cuttage is taken root that improves is provided, the method is the climatic characteristic special according to arid biogeographic zone, adopt simple plastic greenhouse to set up shade net topmost, micro-mist humidifying system is installed in canopy, slotting machine is installed the facilities such as micro-spray device, regulation and control cuttage seeding is at the required light of different times, temp. and humidity environmental condition, to reaching the object that improves rooting efficiency, it is high that the method for the invention is that fast breeding breeding has been opened up a reproductive efficiency strong sprout, the seedling-cultivating method that cost is low, for flat Europe hybrid hazel spread afforestation, Quick is for breeding strong sprout.

A kind of method that the flat Europe of arid biogeographic zone hybrid hazel epicormic branch cuttage is taken root that improves of the present invention, follows these steps to carry out:

The simple and easy plastic tunnel of a, foundation long 70m, wide 9m, the high 3m in top;
