Intermediate propagation method for jatropha curcas

Abstract

The invention relates to an intermediate propagation method for jatropha curcas. The intermediate propagation method for jatropha curcas comprises three steps of seedbed preparation, cutting slip treatment and seedbed management. The traditional seeding culture method is changed by using sand as a seedbed; the temperature of the sand which is tedded is high, so that plant diseases and insect pests are greatly reduced; after the sand is sterilized and fertilized, the vent ability and the high temperature of the seedbed are guaranteed; requirements of high temperature, less plant diseases and insect pests and enough nutrition in the growing process of seedlings of the jatropha curcas are met; the method is simple and is easy to operate and low in cost; and moreover, the period is short, and the yielding capacity is high, so that the intermediate propagation method for jatropha curcas is particularly suitable for factory-like and large-scale production.

Description

technical field [0001] The invention relates to the technical field of plant propagation, in particular to a rapid propagation method of Jatropha jatropha. Background technique [0002] Jatropha is a deciduous shrub or small tree that grows every year. It likes sunshine, but is afraid of cold and waterlogging. The oil content of Jatropha jatropha fruit is between 40-60%, which exceeds that of common oil crops. It also has broad development and application prospects in biomedicine and pesticides, and is a renewable resource with very broad development prospects. Jatropha oil contains saturated fatty acids such as palmitic acid and stearic acid and unsaturated fatty acids such as linoleic acid. The physical and chemical properties of Jatropha oil are very close to petroleum, and it is recognized as the most promising biodiesel energy plant. Therefore, planting jatropha to obtain biodiesel is an important means of developing renewable energy and has great economic and social v...

This patent directly uses the field management method to carry out hardwood cuttings, but the soil in the field cannot provide the best seedling environment, because although the soil can provide a good nutritional environment, the exposed lower cut slope is still very easy to be infected, resulting in Low survival rate and low rooting rate caused by pests and diseases
