Method for promoting cutting rooting of improved variety of carya illinoinensis

Abstract

The invention discloses a method for promoting cutting rooting of an improved variety of carya illinoinensis and belongs to the technical field of asexual reproduction and seedling culture of plants.The method comprises steps as follows: selection of a cutting period, shearing and treatment of cuttings, temperature and humidity management of a cutting bed, rooting culture of an aerosol cultivation device and the like. The method is simple, short in cycle and higher in rooting rate, more importantly, the problem of no rooting of cuttings of the variety is broken through, and the method has important application and promotion value in production and cultivation of seedlings of the carya illinoinensis.

Description

technical field [0001] The invention relates to the technical field of asexual propagation and seedling cultivation of forest trees, in particular to a method for promoting the rooting of cuttages of fine hickory varieties with thin shells. Background technique [0002] Shelled Pecans ( Caryaillinoinensis ), the trade name is Pecan, which is a world-renowned nut tree species. It has been introduced into my country for more than 100 years. In the early stage of development, due to reasons such as backward cultivation technology and low market demand, the industrialization development was slow. In recent years, with the increasing market demand and the continuous improvement of cultivation techniques, the pecan industry has developed rapidly. With the continuous increase of the planting area, we are faced with a very serious problem, that is, the quantity of strong seedlings of good varieties is far from meeting the demand of the nursery stock market. The main reason for th...

Problems solved by technology

[0003] The research on the cutting propagation technology of pecan with thin shell mainly includes the "hard branch cutting method of American hickory" invented by Wang Zhengjia and others (patent publication number: CN103181284A) and the "hard branch cutting method of American hickory" invented by Liu Yongzhi and others (Patent publication number: CN103181284A). Although the former has a rooting rate of 80%, it can only be cut in late March every year. The time is short and there are few cutting batches. The latter can be cut from winter to spring, but the rooting rate is only 59.26%. %, and are only related to seedlings, such as figure 2 and image 3 As shown, the seedlings can take root even without the rooting culture of the aerosol device, but the rooting effect is better after the rooting culture of the aerosol device; but the above two methods have no obvious effect on the cutting rooting of the variety seedlings, that is to Seedlings will not take root, such as Figure 4 shown
