Cottage breeding method of sabina przewalskii

Abstract

The invention discloses a cottage breeding method of sabina przewalskii, comprising the following steps: manufacture of a cottage seedling bed: manufacturing a seedling bed on the seedling culturing ground in a greenhouse in the spring of the current year; and covering fine sand and mycorrhiza soil as cottage matrix; strip picking: in the middle of May to June, selecting healthy, strong, pest and disease-and-damage-free sabina przewalskiiseedlings at the age of 3-5 with good growth and development for picking strips; and cutting processing: placing the cutting into clear water for soaking, drying rapidly, respectively placing into ABT1 rooting powder and potassium permanganate solution for respectively soaking for one time and then carrying out cottage; digging holes on the cottage seedling bed and obliquely cutting, and compacting the cutting hole; leading the cutting bed and the cutting to be fully contacted; spraying with carbendazim or Tuzet and copper abietate for once every half a month, thus preventing root rot of sabina przewalskii seedlings. The method of the invention greatly improves propagation coefficient, can shorten seeding culturing period, has high cottage seedling culturing survival rate, and can enable the cultured nursery stock to keep excellent characters of parent trees.

Description

technical field

[0001] The invention relates to a seedling raising technology, in particular to a cutting seedling raising method of difficult-to-root coniferous trees. Background technique

[0002] Qilian juniper (Sabina Przewalsbii Kom) is a unique tree species on the northeast edge of the Qinghai-Tibet Plateau in my country, and it is distributed in Gansu, Qinghai, Sichuan and other provinces (regions) in China. The main distribution area in Gansu is located between 98°-104° east diameter and 33°50′-40°30′ north latitude, including Sunan, Zhangye, Minle, Shandan, Yongchang County, Wuwei, Gulang, Tianzhu In other counties, the sunny slopes, semi-shady slopes, semi-shady slopes, and shady slopes on the northern slope of the Qilian Mountains at an altitude of 2,500 to 3,500 m are mostly preserved as sparse forests or pure forests. It is one of the construction species of Qilian Mountain water conservation forest arbor community, with excellent material, tall tree shape, maj...

[0019] 1. Production of cutting seedbeds: In the spring of the year when the seedlings were raised, a seedbed with a width of 1m and a length determined by the size of the greenhouse was made on the seedling ground in the greenhouse, covered with 8cm thick fine sand + mycorrhizal soil as the cutting substrate for cutting nursery.

[0020] 2. In mid-May, select 3-year-old Qilian juniper seedlings that are robust, free from diseases and insect pests, and have good growth and development, and pick strips. The cuttings are 2-year-old complete side branches with a base diameter of 0.20cm, and cut into 12cm-long cuttings, every 40 The cuttings are bound as a bundle, and the terminal buds are kept intact. The incision is in the shape of a "horseshoe", and the epidermis and xylem are not separated.

[0021] 3. Treatment of cuttings: first soak the bundled cuttings in clean water for 24 hours, then dry the water rapidly, and then place them in ABT1 rooting powder with a concentration o...

[0025] 1. Production of cutting seedbeds: In the spring of the year when the seedlings were raised, a seedbed with a width of 1m and a length determined by the size of the greenhouse was made on the seedling ground in the greenhouse, and the fine sand + mycorrhizal soil covered with 10cm was used as the cutting substrate for preparation. Seedlings raised by cuttings.

[0026] 2. In mid-June, select 5-year-old Qilian juniper seedlings that are robust, free from diseases and insect pests, and have good growth and development, and pick them. The cuttings are required to be 3-year-old complete side branches with a base diameter of 0.30cm, and cut into 15cm-long cuttings. Every 60 The cuttings are bundled into a bundle, and the terminal buds are kept intact. The incision is in the shape of a "horseshoe", and the epidermis and xylem are not separated.
