Problems solved by technology

[0003] The propagation method of Bauhinia canadenica is mainly grafting, and Bauhinia, giant bauhinia or canadenalis can be used as rootstock, but the survival rate of grafting is low, and the cutting technology is not yet mature, so a kind of technology is provided with perfect technology and high survival rate. The cutting method is necessary to solve the field of propagation of the purple leaf Bauhinia canadensis

Embodiment 1

[0012] Mix peat: frog stone: perlite in a ratio of 1:1:1 as the cutting substrate, put it into a 72-mesh plug tray for use; use 500mg of indole acetic acid, vitamin B 1 4mg, 40g of sucrose, 1ml of chlorothalonil and 1kg of water are prepared as a rooting agent for later use; in the morning when the weather is clear in summer, the semi-lignified branches of the year on the upper part of the canopy of the purple leaf Canadian Bauhinia tree without disease are selected as cuttings, and the prepared rooting agent After soaking in the medium for 5 minutes, insert it into the prepared substrate; after inserting, water it thoroughly, and put it under the intermittent spray of full sun. After 15 days, callus tissue will appear at the bottom of the cuttings, and it will start to take root in about 30 days. After 55 days, it can be transplanted and survived. The rate is 96.53%.

Embodiment 2

[0014] Mix peat: frog stone: perlite in a ratio of 1:1:1 as the cutting substrate, put it into a 72-mesh plug tray for use; use 600mg of indole acetic acid, vitamin B 1 6mg, 60g of sucrose, 1.5ml of chlorothalonil and 1kg of water are prepared as a rooting agent for later use; in the morning when the weather is fine in summer, the semi-lignified branches of the year on the upper part of the canopy of the purple leaf Canadian Bauhinia tree without disease are selected as cuttings, and the prepared rooting agent is used as cuttings. After soaking in the agent for 5 minutes, insert it into the prepared substrate; after inserting, pour water thoroughly, put it under the intermittent spray of full sun, and calluses will appear at the bottom of the cuttings in about 17 days, rooting will begin in about 30 days, and it can be transplanted in about 55 days. Planted, the survival rate was 98%.

Abstract

The invention discloses a twig cutting method of Cercis Canadensis Forest Pansy. The method comprises the following steps of mixing turf, silica and perlite in a proportion of 1 to 1 to 1 to use as a cutting matrix; using 500 to 600mg of heteroauxin, 14 to 16mg of vitamin B, 40 to 60g of sugarcane and 1 to 1.5ml of chlorothalonil, and adding 1kg of water to prepare into a rooting agent; cutting in summer, selecting an annual semi-ligneous branch at the upper part of a disease-free crown as a cutting slip, soaking in the prepared rooting agent for five minutes, and inserting into the prepared matrix; and after inserting, thoroughly watering, intermittently spraying under the full-sun condition, curing tissues growing at the bottom of the cutting slip within about 15 to 18 days, rooting within about 30 days, and transplanting within about 55 days. The survival rate is 95% to 98%.

Description

technical field [0001] The invention belongs to the greening and afforestation technology, in particular to a twig cutting method of the asexually propagated purple-leaved Bauhinia canadensis. Background technique [0002] Bauhinia Bauhinia is a deciduous tree species of the genus Bauhinia in the Fabaceae family. It is a variety of Bauhinia canada. It is a small tree with a clear trunk, a tree height of 6-9 meters, and a crown width of 8-11 meters. The leaves are bright in spring, summer and autumn. Purplish red, tender shoots are always magnificent red. Leaf blade heart-shaped, base cuneate. Flowers first and then leaves, monoecious, crimson flowers in spring, very bright, flowering period from March to May. Purple-leaved Bauhinia canada has strong adaptability, likes a sunny environment, and is resistant to heat, cold, and drought. Suitable for planting in high dry, sunny places. It can withstand low temperatures of -23°C and is suitable for planting in most parts of t...
