Cutting medium, rooting complex agent and cuttage quick rooting method for American red maple

Abstract

The invention relates to a cutting medium, a rooting complex agent and a cottage quick rooting method for American maple. The medium is composed of fine sand, perlite and coarse sand and has a three-layer structure. The coarse sand forms the lower layer which is 1 to 4 cm thick. The perlite forms the middle layer which is 12 to 25 cm thick. The fine sand forms the upper layer which is 1.5 to 3 cm thick. The particle size of the fine sand is 0.5 to 2 mm. The particle size of coarse sand is 3 to 7 cm. The rooting complex agent for American maple is prepared by adopting water or ethyl alcohol of which the volume fraction is 50 % to 95% as a solvent. 5 to 25 g Grow More fertilizer or monopotassium phosphate, 1 to 4 g vitamin C, 1 to 5 g vitamin B and 0.5 to 2.5 g indolebutyric acid are added into each 1000 g solvent and are blended uniformly.

Description

technical field [0001] The invention belongs to the technical field of plant planting, and in particular relates to an American red maple cutting substrate, a rooting compound and a method for fast rooting American red maple cuttings. Background technique [0002] American red maple is the general name of red maple in North America. Its botanical name is Acer safflower, Aceraceae, Acer, a deciduous tree, native to the United States and Canada, and was introduced into China around 2000. It is often called the United States. red maple. With the improvement of people's living standards and the improvement of people's appreciation of the surrounding environment, American red maple is widely used in parks, residential areas, and streets for planting. It can be used for landscaping and street trees, and is deeply loved by people. One of the ideal color-leaved tree species.

AI Technical Summary

Problems solved by technology

[0003] At present, most of the American red maple is cultivated in the market by asexual propagation of cutting seedlings. The main problems in the large-scale production method of cutting and breeding American red maple in the greenhouse are as follows: 1. The cost of cutting substrate in the cutting and seedling raising facilities of American red maple currently exceeds the total The cost accounts for the highest proportion: Most of the cutting substrates contain more than four ingredients, and the substrates generally contain expensive raw materials such as vermiculite and / or peat soil, among which the cost of vermiculite is 3-4 times that of perlite, peat The cost of soil is about 10 times that of perlite

2. American red maple belongs to the type that is difficult to root, and the rooting is slow. Most of the existing technologies have the highest rooting rate in 22-30 days, and there is the problem of high cost of cutting substrate in the first point.
