example 1

[0010] Example 1: Select 500 beautiful arrowroot plants that grow robustly, have no pests and diseases, and have between 15 and 18 leaves, and pour the pot soil with pure water one day before dividing the plants. When dividing the plants, the mother plant is taken out of the pot, the permanent soil is removed, and the densely grown plants are divided with a sharp knife along the growth direction of the underground rhizome. 1 plant with 5 to 6 leaves is divided into 1500 plants in total, and then Smear the wound with 1g / L aqueous solution of chlorothalonil, then dip it in 2g / L aqueous solution of rooting powder (Guoguang brand), plant in the 14cm pot soil, pour pure water to irrigate the whole pot soil, do not fertilize within 1 month, only water The PH value of pure water is 5.5-6.0, keep the humidity above 90%, and the light is 7000-9000lux, accept 7-8 hours of light time every day, cover it with non-woven fabric within 3 weeks after planting, and spray the PH value with a spr...

Abstract

The invention belongs to the technical field of plant cultivation. A method for dividing and cultivating Calathea veitchiana comprises the following steps: selecting a plant of which the number of the blades is between 15 and 18, and completely watering pot soil with water one day before dividing; falling the stock plant out of a pot in dividing, removing original soil, dividing the thick growing plant by a knife along the growing direction of underground rhizomes; taking 5 to 6 pieces of blades as an individual plant, applying 1-1.5g / L of chlorothalonil aqueous solution to the wound; dipping the plant in 2-2.5g / L of rooting powder aqueous solution; planting the plant in the pot soil, completely watering the whole pot soil with water; not applying fertilizer in one month, watering the plant by water with pH value of between 5.5 and 6.0, maintaining the humidity to be over 90 percent, and illumination of between 7,000 and 9,000lux; and illuminating the plant for 7 to 8 hours per day, and covering in three weeks after planting.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to the technical field of arrowroot cultivation. Background technique [0002] Beautiful arrowroot (calathea Roseopicta), also known as rainbow arrowroot, has round, leathery leaves, dark green leaves, light green irregular pinnate spots along the midrib, and leaf backs. Purple, beautiful arrowroot is currently mainly used to obtain high-quality seedlings through tissue culture. But the low survival rate of its ramets has always been an insurmountable problem. Contents of the invention [0003] The invention aims to overcome the deficiencies of the prior art, and provides a method for branch propagation of the beautiful arrowroot. [0004] The branch propagation method of beautiful arrowroot is characterized in that the plants with 15-18 leaves are selected, and the pot soil is thoroughly poured with water 1 day before the branch; Divide the densely growing plant with...
