Tilia miqueiana green branch cuttage method with nutrition pot substrates

Abstract

The invention discloses a tilia miqueiana green branch cuttage method with nutrition pot substrates. The tilia miqueiana green branch cuttage method with nutrition pot substrates comprises the steps of placing nutrition pots loaded with mixed substrates of turf and garden soil in the volume ratio being (2:1) to (3:1) on a cuttage bed, and building a film covering arched shed and a shading shed frame; in the middle ten days of April to the last ten days of June, collecting annual tender twigs as cuttings, under moisture keeping and fresh keeping condition, performing cutting to obtain half-lignified cutting slips of which the length is 10-12cm, reserving one leaf at each top end, and performing cutting off treatment on basal parts; and performing macerating treatment on the cutting slips inrooting liquid, inserting the cutting slips after the macerating treatment in the mixed substrates of the nutrition pots, sequentially spraying mist for replenishing water, spraying sterilizing pesticides, and performing covering with films and shading nets. Through the adoption of the cuttage method provided by the invention, the highest cuttage rooting rate of tilia miqueiana green branches canreach 90%, and root systems of cuttage plantlets are developed; later-stage seedling hardening and transplanting links are simplified, operations are convenient, root systems are not damaged, and transplanting survival and seedling growth are facilitated; and the cuttage bed is arranged without limit by land parcel conditions, the production cost is low, and quick reproduction and production application of tilia miqueiana nursery stocks are facilitated.

Description

technical field [0001] The invention relates to the technical field of seedling propagation of woody plants, in particular to a Nanjing linden nutrient bowl substrate cutting method. Background technique [0002] Nanjing Tilia ( Tilia Miqueiana ) belongs to Tiliaceae, Tilia is a tall deciduous tree, which is a unique species in my country. Nanjing Tilia can be used as timber tree species, medicinal plants, honey plants, and urban and rural greening tree species. However, due to the difficulty in propagating this tree species, it is greatly restricted in garden application, so it has not been effectively promoted so far. [0003] Cutting propagation can produce seedlings in the same year, which is one of the effective ways for rapid propagation of garden seedlings. Some progress has been made in the application research of Nanjing bass seedling rapid propagation. The highest rooting survival rate of green branch cuttings can reach 80% to 90%. However, they are all carried o...

Problems solved by technology

[0004] Generally speaking, Nanjing linden cuttings are propagated and raised under the existing high-standard facilities. After the cuttings take root, it is necessary to move the cutting pool out of the outdoor hardening and adjust the environmental conditions of temperature control, shading, and ventilation; In the field, it is necessary to take out the cutting seedlings, which will easily damage the root system, easily affect the survival rate of transplantation, prolong the slow seedling period, or need to increase the maintenance facilities and costs for moisturizing and shading. The existence of these problems will affect the green branches of Nanjing Linden Popularization and application of cutting seedling raising technology
