Cutting propagation method for jasmine

Abstract

The invention discloses a cutting propagation method for jasmine. The method includes the following steps that 1, a cutting shoot is prepared, a jasmine root system without obvious germ infection or scars is selected as the cutting shoot, the diameter of the jasmine root system is larger than or equal to 2 mm, the cutting shoot is cut into a small segment with the length ranging from 4 cm to 10 cm, the upper end of the cutting shoot is cut into a flat opening, the lower end of the cutting shoot is cut into a 45-60-degree inclined opening, excessive or too long fibrous roots on the root system are sheared off, the length of the left fibrous root is not larger than 1 cm, and meanwhile disinfection is conducted; 2, the cutting shoot is treated; 3, cutting treatment is conducted. According to the cutting propagation method for jasmine, the cutting shoot selected for cutting is an abandoned root system generated by clipping or cutting-off or shaping in the jasmine transplanting, pot replacing and large land seedling updating processes, a new path is provided for jasmine cutting propagation, and maximum utilization of resources is achieved. The requirement of the cutting shoot for the maturity of the jasmine root system is low, root system materials can be available and used for cuttage at any time, and the influences of materials or seasons are low. Operation is convenient, and the cuttage survival rate is high.

Description

technical field [0001] The invention relates to a seedling vegetative propagation method, in particular to a cutting propagation method using the root system of jasmine. Background technique [0002] Jasmine (Jasminum sambac (L.) Ait.) is an evergreen shrub or vine of Oleaceae Jasmine, originally distributed in India, Arabia, and the Persian Gulf, and now in tropical and subtropical areas such as China, India, Iran, Spain, France, and Italy. Widely cultivated. On the one hand, because of the unique aroma and medicinal value of its flowers, jasmine has been regarded as an important raw material for scented tea and essence for many years; It has a very high ornamental value in gardens, and is widely used in flower mirror configuration, flower hedge planting and indoor potting. China is currently the main production area of ​​jasmine in the world, and it is planted in large areas in Guangxi, Yunnan, Fujian, Guangdong and other provinces and regions. Among them, Hengxian Count...

Problems solved by technology

[0003] At present, the demand for jasmine seedlings in the market is increasing day by day. Due to the extremely low seed setting rate of jasmine, the source of its seedlings is mainly asexual reproduction, among which stem cuttings are the main propagation. However, stem cuttings have a higher demand for stem quality. High, semi-lignified branches in the current year are the best. Branches that are too lignified or too tender are not suitable for cuttings. On the one hand, it will affect the survival rate of cuttings, and on the other hand, it will also have a great impact on the survival rate of transplanting and seedling quality.

In addition, because a large number of cutting branches has a great impact on the yield of jasmine flowers, it is not suitable to harvest stems during the flowering period of jasmine and 1-2 months before the buds are born every year. segmental cuttings, so the annual cycle for seedling propagation cannot be achieved
