Embodiment Construction

[0023] A kind of planting method that improves blue hydrangea commodity rate, adopts following steps to carry out:

[0024] ①The method of hydrangea seedling cultivation is as follows: take natural peat, fermented agricultural solid waste (crop stalk) and add puffed minerals to mix and prepare the matrix according to the mass ratio of 25%-25%-50%, and dip it in the water-soluble rooting agent in the facility shed Seedlings raised by cuttings.

[0025] ②Adopt steel-frame greenhouse facilities, and are equipped with shading and integrated water and fertilizer facilities.

[0026] ③Rhizosphere soil improvement:

[0027] 1) Increase the application of organic fertilizer, and apply 0.12-0.25 kg of organic fertilizer that meets the quality requirements of NY 525-2012 organic fertilizer for each pond.

[0028] 2) Adjust the pH value of the rhizosphere soil, adjust it when the soil pH value is not in the range of 4.5-5.5, for the soil with a pH value higher than 5.5, use an acidic s...

Abstract

The invention relates to a planting technology of blue hydrangea, and especially relates to a planting method for improving commodity rate of blue hydrangea. The planting method can solve the problemof low commodity rate of blue hydrangea. The planting method is carried out by (1) hydrangea germinating method; (2) use of a steel frame greenhouse facility matched with shade and integration of water and fertilizer; (3) root soil improvement; (4) planting: the planting method is single-ridge and single-line planting, single-ridge and double-line planting, and others; 800-1000 plants are plantedper mu; reservoir is excavated and plants are transplanted; (5) fertilization; (6) irrigation: the sandy loam adopts trickle irrigation and soil with heavy stickiness adopts micro-jet according to thesoil condition; (7) light temperature control in the facility; (8) trimming; (9) prevention and treatment of plant diseases and insect pests; (10) flower picking. The hydrangea color is pure and bright blue; thus the blue hydrangea with good quality and high commodity rate can be acquired.

Description

technical field [0001] The invention relates to the planting technology of blue hydrangea, in particular to a planting method for improving the commercial rate of blue hydrangea. Background technique [0002] Hydrangeas are native to the provinces south of the Yangtze River Basin in my country, and are mostly used as potted plants in the north. They are subtropical tree species. In Yunnan, Guangdong and other places, they are mostly evergreen shrubs, while in slightly colder regions, they are mostly deciduous and dormant. Hydrangeas mostly grow in valleys and forests and stream slopes. They like warm and humid climate conditions, like half shade, and have poor cold resistance. Intolerant to drought, avoid direct sunlight. [0003] The fertilizers currently on the market can only ensure that the hydrangeas turn blue, but the purity of the blue color is not enough and it is white. Commercialized hydrangeas are fresh cut flowers, mainly used in weddings, festive occasions an...
