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
The invention belongs to field of plant growing technology, particularly the arrowroot cultivation technical field.
Background technology
Calathea roseopicta ((calathea Roseopicta), ginger order Marantaceae Xiao Maranta has another name called the rainbow arrowroot; Leaf is circular, keratin, blade face dirty-green; The irregular pinniform spot of arteries and veins tool light green in the edge, blade back is a purple, Calathea roseopicta mainly obtains high quality seedling with tissue culture method at present.But its plant division survival rate is low is only to be difficult to the problem that overcomes always.
Summary of the invention
The present invention is intended to overcome the deficiency of prior art, and a kind of method for dividing and breeding Calathea veitchiana is provided.
Method for dividing and breeding Calathea veitchiana is characterized in that, selects the plant of blade between 15～18, irrigates basin soil at preceding 1 day water of plant division; During plant division maternal plant is deducted in basin, remove place soil, along the underground rhizome direction of growth plant that grows densely is cut with scraper; With 5～6 leaves is 1 strain, smears wound with tpn 1～1.5g/L aqueous solution then, dip in root-inducing powder 2～2.5g/L aqueous solution again after; Plant in the middle of basin soil, water irrigates whole basin soil, does not apply fertilizer with interior in 1 month; Only water pH value and be 5.5～6.0 water (pH value of water or pure water is that phosphoric acid or potassium hydroxide are regulated), keep humidity more than 90%, illumination 7000～9000lux; 7～8 hours every days of light application time, the plantation back covered in 3 weeks.Also comprise on the basis of the above, keep 25～28 ℃ of temperature daytimes in 3 months in the middle of the plant division process and after the plant division, 22～24 ℃ of nights.
Described water is pure water.
Described covering adopts nonwoven to cover.
Plantation back interior use of 3 week sprayer spray pH value is that the pure water of 7.0 (regulating with phosphoric acid or potassium hydroxide) keeps the moistening of blade face.
Comprise also that on the basis of the above plant division in 3 months, was watered water and fertilizer synchronization weekly 1 time after 1 month, the flower of EC value 0.7ms/cm is No. 3 15-20-25 the more.
Beneficial effect is used the inventive method breeding Calathea roseopicta, Calathea roseopicta plant division survival rate is reached more than 98%, and do not have germ and infect.
Embodiment
Example 1:Select robust growth, no damage by disease and insect, the Calathea roseopicta of plant leaf between 15～18,500 strains altogether irrigate basin soil preceding 1 day of plant division with pure water.During plant division maternal plant being deducted in basin, remove place soil, the plant that grows densely is cut along the underground rhizome direction of growth with scraper, is 1 strain with 5～6 leaves; Be divided into out 1500 strain plant, smear wound with the tpn 1g/L aqueous solution then, dip in root-inducing powder (state's light board) the 2g/L aqueous solution again after; Plant in the middle of 14 ㎝ basin soil, the pouring pure water irrigates whole basin soil, does not apply fertilizer with interior in 1 month; Only watering the pure water pH value is 5.5～6.0, keeps humidity more than 90%, illumination 7000～9000lux; Accept 7～8 hours light application time every day, plantation back covered with nonwoven in 3 weeks, and using sprayer spray pH value during this period is that 7.0 pure water keeps the moistening of blade face.
Keep 25～28 ℃ of temperature daytimes in 3 months in the middle of the plant division process and after the plant division, 22～24 ℃ of nights;
Plant division in 3 months, was watered water and fertilizer synchronization weekly 1 time after 1 month in addition, and the flower of EC value 0.7ms/cm is No. 3 15-20-25 the more.
Under above-mentioned environmental condition, through 3 months maintenance, the plant division survival rate of plant reached 98%, and courses of infection does not take place.
Example 2:Example 2 is with routine 1 other is identical, and difference is for to be respectively tpn 1.5g/L (weight and volume ratio) with two kinds of reagent concentrations, and root-inducing powder 2.5g/L (weight and volume ratio) tests the influence to the survival rate of Calathea roseopicta.
Result of the test shows, when two reagent increase 0.5g/L respectively, keeps the plant division survival rate of plant to reach 98% equally, and courses of infection does not take place.
