Roots and stems section-cutting seedling-growing method for paris yunnanensis franch

Abstract

The present invention provides a method for root fragment seedling cultivation of the Yunnan Manyleaf Paris Rhizome, which is to adopt the rhizome of the Yunnan Manyleaf Paris Rhizome to be fragmented in the period from March to April or in the period from September to October. The fragmented rhizome is immersed in a 2 to 10 mg/ L Cytokinin 6-BA for 12 to 36 hours. The rhizome is laid indoor with one layer of soil. The thickness of the soil is 3 to 5 cm and the total stack height is 10 to 50 cm; the moisture content of the soil is kept at 50 percent to 70 percent; after the rhizome is sprouted to be one to three, the seedling is moved to a green house and is put on a seedling bed with a row distance of 2 to 5 to 2 to 5 cm in a high density; two years later, after the ramet of the seedling, the seedling can be moved to be cultivated in the farmland. Adopting the present invention, the loss rate of the root fragment material is reduced from 40 percent of the conventional farmland direct-planting fragment to 10 percent or less; the fragmented multi-sprout breeding rate is increased by 2 to 4 times; the general sprouting rate is increased by 3 to 5 times; 40 to 60 percent of the breeding material, the land and the management cost are saved with the present invention of integrated seedling culture and transplanted in the farmland compared to the traditional way of direct planting. The operability of the technology is strong and is easy for industrialization; the investment is less; the cost is low; the efficiency is high and the present invention has important realistic significance for effectively resolving the shortage of the seedling of Yunnan Manyleaf Paris Rhizome.

Description

technical field [0001] The invention relates to a method for raising seedlings by cutting rhizomes of Chonglou yunnanensis. Background technique [0002] Polyphylla yunnanensis (Paris polyphylla var.yunnanensis (Fr.) Hand.-Muzz), is a perennial herb of the genus Polyphylla var.yunnanensis (Fr.) in the family Liliaceae. API. Since the history, people's use of chrysanthemum has always been maintained by natural wild resources. Due to long-term excessive plundering and excavation, wild chrysanthemum has been destroyed by human beings and is now on the verge of exhaustion. In recent years, there has been a certain artificial planting area of ​​Chonglou yunnanensis, but at present, the planting materials of Chonglou yunnanensis are mainly planted directly with wild germplasm or cut into sections of rhizomes for direct planting in field. Planting the field directly with cut rhizomes can save labor and is easy to operate. It is currently the planting method adopted by many heavy ...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the three main problems existing in the current artificial planting of Chonglou yunnanensis, and provides a technique for asexual reproduction and seedling cultivation of Rhizome of Yunnan Chonglou by cutting into sections. After the rhizome is cut into sections, it adopts chemical reagent treatment and centralized seedling cultivation in facilities, and strictly controls the humidity conditions. , reduce the loss rate of cut rhizome material from 40% to less than 10%, increase the multi-bud reproduction rate of cut sections by 2-4 times, and increase the total emergence rate by 3-5 times compared with conventional fields, and transplant after centralized seedling cultivation Field can save 40-60% of propagating material, land and management costs compared with the traditional method of direct planting
