Problems solved by technology

[0003] The technical task to be solved by the present invention is to provide a new method for the problem that the branches are easy to rot during the cutting process, the required length of the cutting branches is large, and there are certain requirements for the soil quality of the cutting seedbed, and the watering after cutting is difficult to control. The method of raising seedlings by cuttings

Embodiment

[0017] The location is Shuangjiang County, Yunnan Province, where the annual average temperature is 19.5°C, the highest temperature over the years is 38.1°C, and the lowest temperature over the years is -2.1°C. The average rainfall over the years is 1015.2 mm, the average evaporation over the years is 2308.1 mm, and the average relative humidity over the years is 76%. The main climate features are: distinct dry and wet seasons, obvious three-dimensional climate, no severe cold in winter, no severe heat in summer, drought and semi-arid in winter and spring. The cuttings were collected in late February 2007. The cuttings from Lincang, Baoshan and Dali were collected as test objects, with one seedbed in each region. The cutting site is provided by the local county forestry bureau, based on the open-air nursery of the county forestry bureau, at an altitude of 1100 meters.

Abstract

The invention relates to the technical field of plant clonal propagation, in particular to a method for raising seedlings by cutting of Jatropha curcas Linn, which comprises the steps of strips picking, seedbed preparation, lopping, cuttage, management after cuttage and management before afforestation, and is characterized in that the upper layer of the seedbed is a coarse river sand layer, and the lower layer thereof is a soil layer. When in cuttage, the part of the branch buried in the ground is cut into the river sand matrix of the upper layer, but is not suitable for rising over the river sand to penetrate into the soil layer. As the entire strip is in the coarse river sand, the good permeability of the strip is guaranteed, simultaneously the strip rotting probability caused by waterlogging is also greatly reduced, after taking root, the strip penetrates into the soil so as to absorb the soil nutrient well, thus ensuring the quality of nursery stock root system; simultaneously the rootage powder processing is not needed in strip cutting, and only the immersion and disinfection by using carbendazim is needed, thus reducing the cost and being a set of method which has simple operation and comparatively extensive management.

Description

technical field [0001] The invention relates to the technical field of plant clone propagation, in particular to a method for raising seedlings by cuttings of tung tree. Background technique [0002] Jatropha curcas L., also known as Jatropha curcas L., is a deciduous shrub or small tree of the family Euphobiaceae (Eu-phobiaceae), genus Jatropha, with a height of 2-5m; the root system is very developed, Old stem grayish brown, branchlets grayish green to light green; single leaves alternate, ovoid, nearly equal in length and width, 3-5-lobed or not split, petiole up to 15 cm; flowers unisexual, monoecious, arranged in axillary Or terminal cymes; seeds oval, 18-20mm long, 11mm in diameter. Glycotonia is widely distributed in tropical and subtropical regions, and has applications in industry, agriculture, environmental protection and ecological construction. It is currently being vigorously developed as a bioenergy tree species. The outstanding problem in the current constru...
