Method for propagating Millettia speciosa Champ. seedlings using cottage

Abstract

The invention discloses a method for propagating Millettia Speciosa germchit by cuttage, including first-phase preparation and later management: 1) during the first-phase preparation, Millettia Speciosa tresses are selected and cut into stem segments for spare use; river sand and coco bran are evenly mixed according to certain proportion to obtain a substrate for spare use; 2) during the later management, Millettia Speciosa stem segments are dipped with root stimulate at the base parts and then stuck into the substrate; the stem segments are watered to promote the close contact between the base parts thereof and the substrate; the stuck stem segments are shaded for culture, with the moisture of the substrate and air humidity being guaranteed; after taking root, the stem segments are fertilized with urea solution until the germchit grows up. The invention has the advantages of simple process flow and low manufacturing cost, and, effectively utilizes the scrap Millettia Speciosa tresses; by optimizing the root stimulate and the substrate formula, the invention improves the culture conditions and increases the survival rate of the stuck stem segments. The method has high feasibility, simple operation, low cost input and high survival rate and achieves the dual purpose of recycled utilization of resources and batch production of the germchit.

Description

Technical field [0001] The invention belongs to the field of agricultural biotechnology, and specifically relates to a method for vigorously planting seedlings by using cuttings to propagate cattle. Background technique [0002] Niu Dali belongs to the genus Cistula of Papilionaceae, which was originally published in "The Essentials of Herbal Medicine". Used for lumbar muscle strain, rheumatoid arthritis, lung heat, lung deficiency cough, tuberculosis, chronic bronchitis, chronic hepatitis, spermatorrhea, vaginal discharge, etc. Since the 1970s, it has been used in the production of proprietary Chinese medicines as raw materials for Zhuangyao Jianshen pills and Qiangli fitness capsules. It has been widely used in Guangdong and Guangxi. Since the end of the last century, people in Guangdong, Hong Kong, Macau and other places have generally used cattle to make vigorously. The consumption of Liangtang has far exceeded that of pharmaceutical companies, and it is increasing year by ye...

Problems solved by technology

[0003] The traditional breeding method of Niu Dali is seed propagation. The problems of this method are: (1) seed resources are scarce and batch collection is difficult; (2) seeds have a short lifespan and cannot be stored at low temperature, so they cannot be sown regularly to raise seedlings; (3) seeds germinate The rate is low, only reaching about 45%; (4) The root system of seedlings is dominated by taproots, and the number of tubers formed is small, and the yield is low

The existing problems of cutting propagation are: (1) the survival rate of cutting propagation is low, or even all die; (2) cutting resources are in short supply, and mass propagation is difficult

These branches are generally not used as explants for tissue culture due to the difficulty of sterilization. At the same time, because the cutting technology is immature and not used as cuttings, they are often discarded, resulting in a waste of resources.
