Embodiment

[0019] The project chooses Kangjia Village, Yuanma Town, Yuanmou County, Chuxiong Prefecture, Yunnan Province as the base. The base has a dry subtropical climate, with an altitude of about 1100 meters, an annual average temperature of 21.9°C, an extreme maximum temperature of 42.0°C, and an extreme minimum temperature of -0.8 ℃, the annual sunshine is 2220.3-3435.8 hours, the annual accumulated temperature is 7996.1 ℃, the annual average rainfall is 611.1 mm, the rainy season is generally in July-August, the water is relatively scarce, and the temperature difference between day and night is large. The soil is acidic sandy loam, and the soil is divided into 3-4 layers.

[0020] The source of local cutting materials has been investigated. Wild jatropha grows very widely, and the source of cutting materials is relatively easy. The growing place is generally on a slope with a slope greater than 60 degrees. According to the results of field experiments, we summarize the cutting pro...

Abstract

The invention belongs to plant breeding field. The Jatropha curcas breeding cutting technique is to employ hard branch for cuttage and keep seed bed to be wet but not dry. The temperature for cuttage is 25-30 Deg. C, the relative humidity is controlled between 80-90%, and the effective water capacity in soil is 5-10%. The invention overcomes the current technique shortcomings and produces mass and high-quality Jatropha curcas seedling, which can meet large-scale production demand and makes it possible for high added value Jatropha curcas industrial development.
