Abstract

The invention discloses a sabina chinensis cutting and seedling raising method used in a low-temperature environment. The method includes the following steps that firstly, one-year-old branches on two-year-old saplings are selected as cuttings which are 8-10 cm long; secondly, the cuttings are placed in a closed container with the pressure of 0.4-0.6 bar and then taken out after 30-40 min; thirdly, a nutrient solution is evenly sprayed on the cuttings obtained after pressure treatment; fourthly, the cuttings obtained after nutrient solution spraying are subjected to ultrasonic treatment for 15-20 min, wherein the ultrasonic frequency is 30-35 KHz; fifthly, the processed cuttings are vertically inserted into a seedbed, and then a seedling raising accelerant is evenly scattered on the seedbed, wherein 60-80 g of seedling raising accelerant is scattered on each square meter of seedbed. By means of the method, the sabina chinensis cuttings can have a high survival rate in the low-temperature environment, the rooting speed of the cuttings is high, and the requirement for large-scale seedling raising of sabina chinensis in January can be met.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a method for growing seedlings of Shu juniper by cuttings in a low-temperature environment. Background technique [0002] Shu juniper, evergreen tree or small tree, bark brownish-gray, cracked, loosely arranged branches, scale leaves alternately opposite on small branches, fragrant, tough and dense, close to branchlets, occasionally three leaves whorled, apex sharp Or obtuse, slightly inwardly curved, without wax powder, with glands, oval glands, located at the base of the back of leaves, dioecious, rare monoecious. Strong corrosion resistance. Cones ovoid or nearly spherical, purple-black or blue-black when ripe, covered with white powder, 1 seed, ovoid, with resin grooves, blunt ridges on both sides or upper part. The flowering period is April, and the cones mature in October of that year. Practice has proved that the survival rate of cutting seedlings of Shu...
