However, since castor is a monoecious plant with different flowers and cross-pollination crops, sometimes male sterile castor plants (castor bean female single plant) can be found, that is, there are only female flowers on the plant inflorescence, and there are no male flowers. Therefore, conventional methods cannot be used. Seed propagation, so that castor has been greatly restricted in the utilization of heterogeneous

Abstract
The invention discloses a cutting propagation method of ricinus communis, which belongs to the technical field of crop propagation. The method comprises the following steps of: cutting ricinus communis branches of 1-2 years old, retaining one leaf with the leaf area being 20%-25% of the original leaf area on each branch, dipping the cut branches with rooting powder and then inserting into a seedling bed, keeping the air humidity to be 100% in a cutting seedling greenhouse during the period from cutting to rooting. The method provided by the invention overcomes difficulties of the ricinus communis such as large areas, fast moisture evaporation, hollow stems, high lignification extent and difficult rooting; the inarched ricinus communis branches are capable of successfully rooting within a short time of 40 days more or less; the rooting rate is 53%-86.7%, and speediness, orderliness, strong growth vigour and good growth can realized in rootage; the propagation time is short, the operation is concise and easy to master. The invention provides a novel method for protecting the ricinus communis resource, which is capable of keeping excellent individual plants of the ricinus communis and shortening the propagation time. The application of the method provided by the invention in the propagation of female individual plants of the ricinus communis is particularly significant in heterosis utilization.
Description
technical field [0001] The invention relates to the technical field of crop breeding, in particular to a cutting propagation method of castor. Background technique [0002] castor ( Ricinus communis ) belongs to the genus Castor in the family Euphorbiaceae, a dicotyledonous plant, and is an annual or perennial herb. Castor is a special oil source crop for industrial use and has high economic value. The main component of castor oil is tri-12-hydroxy-9-octadecenoic acid glyceride, which is the natural oil with the highest hydroxyl value. Features, can be used as high-grade lubricating oil in aviation, automobile, machinery and other industries; at the same time, castor oil can be made into more than 300 kinds of products, including: dehydrating agent, detergent, emulsifier, surfactant, stabilizer, lubricant , plasticizers, polymer materials and spices, etc., are widely used in national defense, machinery, chemical industry, medicine, textile, printing and dyeing, papermaki...
