Embodiment Construction

[0012] The method for 'Jinwei' hardwood cuttings of the present invention, its preferred embodiment is: every year in mid-March and early April, before the dormant buds of 'Jinwei' germinate, cut 1 The annual thickness is between 0.2-0.6cm without pests and diseases. Cut the hard branches into 5-10cm long cuttings, cut the upper end of the cuttings flat, the distance from the dormant buds is 0.5-1.0cm, and cut the lower end obliquely, put the cuttings in a bundle of 30-50 branches and soak in water for 12-24 hours. The matrix of cuttings is made by mixing muddy soil and perlite in a ratio of 1:1. Before cutting, pour 800 times liquid of 50% carbendazim wettable powder into the matrix to achieve the effect of disinfection. Then dip the 1.5-3.0cm of the base of the cuttings with 75% alcohol for 10-20s, rinse with clean water for 2-3s, then dip the cuttings in the rooting agent for 30-50s, the concentration of the rooting agent is 800-1000mg·L -1 In IBA, the cuttings are finally...

Abstract

The invention provides a 'propagation method for the hard wood cutting of 'golden common vetch''. The propagation method is characterized by comprising the following steps of: selecting the annual 'golden common vetch' branches free of plant diseases and insect pests and with the coarseness within the range of 0.2-0.6cm in March, shearing into cutting slips with the lengths of 5-10cm, and soaking in water for 12-24 hours; dipping the roots of the cutting slips at 1.5-3.0cm for 10-20s by 75% ethyl alcohol, washing by clean water for 2-3s, inserting into 800-1000mg.L<-1> IBA (iso butyl alcohol) solution for 30-50s, and inserting into a matrix mixed by mire soil and perlite according to the proportion of 1:1, wherein the cottage depth is 1/2 of the length of the cutting slips, and one golden common vetch is inserted into every one hole disc; spraying water after cottage, so that the branches are tightly contacted with the matrix; and entering a seedling exercising period when the rooting percentage of the cutting slips reaches up to 60-70% of a sword, and planting when the seedling exercising time is 10-15d. The survival percentage of the cutting slips of 'golden common vetch' propagated by the method disclosed by the invention can reach to be more than 80% of the sword under the condition of a fog system, and the method is ordered in nursery stock, enough in delayed effect, and extremely good in commodity.

Description

technical field [0001] The present invention relates to a cutting propagation method for seedling cultivation, in particular to a cutting propagation method for 'Jinwei' twigs. Background technique [0002] Lagerstroemia indica L., also known as mantanghong, zinnia, itchy tree, etc., is a plant of the genus Lagerstroemia indica. In the hot summer, just when there is a lack of flowers, its flowers bloom like fire, from summer to autumn, and last for a long time. It is a famous summer flower-viewing small tree in my country and even in the world. It is also known as the four summer names together with lily, pomegranate and lotus.
