Problems solved by technology

[0004] The main way of reproduction is asexual reproduction. Its growth characteristics are similar to sugarcane, but the seed joints are smaller than sugarcane, and it is easy to lose water and dry. When planting, it requires far more water than sugarcane, and its natural survival rate is extremely low on dry ground.
At the same time, the current cultivars are poor in cold resistance. The continuous low temperature of about 0°C can freeze the plants and some roots of the emperor bamboo grass to death. The non-test tube rapid seedling breeding experiment carried out by seedlings can make the seedlings of Emperor Bamboo Grass grow rapidly throughout the year, which has great practical significance
According to the literature search, there is no research report on the non-test tube seedling cultivation technology of Huangzhu grass at home and abroad.

Abstract

The invention relates to a method for quick breeding and seedling growing of pennisetum hydridum. The method includes the following steps of establishing a seedling growing bed, selecting materials for being tested, carrying out seed stem cuttage, growing seedlings and leaving a garden. In the seed stem cuttage step, the lower cutting opening of a cuttage cutting wood stem segment is dipped into plant growth regulators and inserted into the seedling growing bed or a cuttage basin filled with matrixes, and the plant growth regulators are one kind of cytokinin, seaweed essence and rooting powder; the matrixes are sand or peat. According to the method for quick breeding and seedling growing of the pennisetum hydridum, seedling growth can be promoted without the limit of seasonality and can be bred all the year around, the qualified seedling percentage for quick breeding and seedling growing of the pennisetum hydridum is generally between 95% and 100%, moving and plantation survival rates are high, the method has a direct significance in solving the problems that the production is influenced due to the low survival rate of the directly planted pennisetum hydridum and seedlings are insufficient after overwintering, and important reference value is provided for preservation and breeding expanding for the pennisetum hydridum of grass-type good seedlings.

Description

technical field [0001] The invention belongs to the technical field of non-test tube rapid propagation of plants, and in particular relates to a method for rapid propagation and seedling cultivation of Phyllostachys japonica. Background technique [0002] Plant non-test tube rapid propagation technology uses micro-domain environmental control technology outside the test tube bottle to create the most suitable environment for plant reproduction, such as temperature, light, water, air, nutrition, hormones, etc., to maximize the physiological potential of plants and make plants The germination and rooting gene is expressed as soon as possible, so as to realize the rapid rooting and seedling growth of plants, and a new type of rapid plant propagation technology that can form a large number of commercial seedlings with cultivation value through multi-generational cycles in the form of seedling propagation. It is not a tissue culture technology, but in essence it combines the prin...
