Cross-filbert cutting and seedling culture method

Abstract

An embodiment of the invention discloses a cross-filbert cutting and seedling culture method which includes the steps: taking a solar greenhouse as a cutting facility; selecting cross-filbert young new tips or sprout tillers as cuttings; inserting the cuttings into a mixed medium of river sand and turfy soil; keeping day illumination intensity to be smaller than 27000lux, air temperature to be 28-38 DEG C and air humidity to be 75%-85%. According to the embodiment, illumination and temperature are suitably controlled, leaf fertilizers are reasonably used, and the rooting rate and the seedlingsurvival rate of the cross-filbert cuttings are increased.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of plant seedling cultivation, and in particular to a method for hybrid hazelnut cutting seedling cultivation. Background technique [0002] Hybrid hazelnut (Corylus heterophylla Fish.×Corylus avellana L.) is an interspecific hybrid cultivar developed by crossing flat hazel (Corylus heterophylla Fish.) as the female parent and European hazel (Corylus avellana L. Pingou hybrid hazel. The hybrid hazelnut has both the strong cold resistance and wide planting area of ​​flat hazelnut and the excellent characteristics of large filbert, high kernel yield and high yield. It is welcomed by the majority of growers, and the planting area has grown rapidly in recent years. [0003] With the rapid development of the hybrid hazelnut planting industry, the market demand for hybrid hazelnut seedlings is also increasing rapidly. At present, the production method of hybrid hazelnut seedlings common...

Problems solved by technology

[0005] In order to solve the problem in the prior art that the rooting rate of hybrid hazelnut cuttings is low and it takes two years to grow seedlings, this invention provides a hybrid hazelnut cutting seedling raising method with a cutting rooting rate of 98% and cuttings that grow seedlings in the same year The specific implementation steps include using a solar greenhouse as a cutting facility, selecting young shoots or sprouts of hybrid hazelnuts as cuttings, and cutting them in a mixed matrix of river sand and peat soil. Within 25 days of cuttings, keep the daytime light intensity less than 27000lux, and the air The temperature is 28°C-38°C, the air humidity is 75%-85%, and the film and sunshade net are removed on the 26th day of cutting, so that the cutting seedlings can complete the late growth in the open air environment;
