Embodiment Construction
[0029] In order to express the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings.
[0030] see figure 1 , the Mexican cypress cutting propagation method provided by the invention comprises the following steps:
[0031] Step 1, cutting preparation; using the greenhouse as the basic facility, setting up a transplanting bed in the greenhouse, disinfecting the cutting matrix of the transplanting bed before cutting, and stirring the matrix evenly;
[0032] Step 2, select the cuttings; take the vigorous branches of the year in the middle of the canopy from the female parent of the Mexican cypress;
[0033] Step 3, cuttings processing; cut off part of the branches and leaves of the cuttings, and cut a horseshoe-shaped incision at the lower part of the cuttings;
[0034] Step 4, cutting; use a glass rod to guide the hole, and cut the lower part of the cutting upright, and the cutting depth is 1 / 3-1 / 2 o...

The invention discloses a cutting propagation method for portuguess cypress, which comprises the following steps: with a greenhouse as a basic facility, installing a slotting machine in the greenhouse; picking robust annual branches in the middle of tree crowns from a portuguess cypress female parent; shearing a part of branches and leaves of the cuttings, and cutting a U-shaped notch in the lower part of the cuttings; by utilizing a glass rod hole, vertically cutting the lower part of the cuttings, wherein the cutting depth is one third to half of the length of the cuttings; after the cutting is conducted, immediately sufficiently watering, and spraying a disinfectant to the cuttings, for disinfection treatment after the surface of a cutting medium is slightly dried; before the cuttings are rooted, keeping the cuttings and the slotting machine wet, reducing the moisture content of the cutting medium after the cuttings are rooted, and spraying the disinfectant for disinfection treatment at regular intervals; and finally transplanting. According to the cutting propagation method for portuguess cypress, the rooting rate of the cuttings can achieve more than 80%, and the transplanting survival rate can achieve more than 90%; the rooting rate is obviously improved, and the propagation efficiency is increased.
Description
technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a cutting propagation method of cypress cypress. Background technique [0002] Mexican cypress is native to the Central American plateau, starting from Chihuahua Province in northern Mexico in the north, extending southward along the Sierra Madre, passing through Durango, San Luis Potosi, Michocan, Mexico, Puebla, Veracruz and other provinces until Harpas and southern Guatemala and Honduras. The horizontal distribution is 15°-27° north latitude, 88°-105° west longitude, and the vertical distribution is 1300-3300m above sea level. [0003] Although the origin of Mexican cypress is located in the subtropical zone, due to the vertical distribution, the original distribution area belongs to warm temperate zone and cool temperate zone climate. The annual average temperature is 10°C-15°C, the annual precipitation is 1100-2200m, the average temperature of the col...
