Industrialized water culture method for metasequoia cuttings

Abstract

The invention belongs to the technical field of plant cultivation, and relates to an industrialized water culture method for metasequoia cuttings. The method comprises the steps of 1, selection and treatment of the cuttings; 2, preparation of a nutrient solution; 3, construction of an industrialized plant water culture system; 4, seedling management. Specifically, the method comprises the steps that the cuttings each of which is about 10 cm long and contains 2-3 buds are cut from metasequoia seed trees which grow well for 2-10 years; one-third parts of the cuttings are soaked in a 10 g / L rooting powder solution for 24 h and then placed in clear water for soaking for two weeks, and the cuttings root under dark conditions; two weeks later, the cuttings are fixed by planting cotton and planting baskets and placed on a perforated foam plate, the foam plate is placed on a water culture box with the nutrient solution, it is ensured that the one-third parts of the cuttings are fully soaked in the nutrient solution, appropriate illumination is supplied, and the growth temperature of metasequoia and the oxygen supplying time of the water culture are controlled; the nutrient solution is changed every week, and the growth condition of the cuttings is monitored in real time; after two months, the survival rate and rooting quantity of metasequoia are measured. It is discovered from results that metasequoia after the water culture by means of the method grows well, the survival rate and the rooting rate are both relatively high, the survival rate after the metasequoia cuttings are transplanted is high, and the trees are beautiful in shape.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to an industrial hydroponic method for metasequoia cuttings. Background technique [0002] Metasequoia glyptostroboides is a large deciduous tree belonging to the family Firaceae. It is native to my country. It is a famous living fossil plant and is a first-class national key protected plant. Metasequoia is light-loving, more cold-resistant, not shade-tolerant, and can withstand high temperatures of 40°C and severe cold of -30°C. It can grow in deep, fertile, moist acidic soils, and in light saline alkaline soils. It grows well in low humidity soil with high soil moisture content. Metasequoia grows fast, with beautiful tree appearance, green feathers and leaves in spring, and colorful fallen flowers in autumn. It is a famous ornamental tree species in gardens. It is used for solitary planting, row planting or group planting in parks, courtyards, lawns, and green spaces. It ...

Problems solved by technology

Nowadays, the cultivation of metasequoia at home and abroad mostly uses different components and different proportions of organic and inorganic substances as substrates for cutting propagation, mainly including hard branch cuttings, tender branch cuttings, one-season cuttings, multi-season cuttings, etc., but cutting propagation of metasequoia cuttings low survival rate
