Embodiment 1

[0020] Management method:

[0021] (1) Plant selection and treatment: select a healthy air pineapple plant (velutina), cut off the dead leaves and broken leaves around the plant, and place it in the greenhouse for recovery for 15 days;

[0022] (2) Soaking in solution: put the plant obtained in step (1) into Cu 2+ The concentration is 100mg / L copper sulfate aqueous solution immersion 40min, then take out, cultivate under natural low temperature outdoors;

[0023] (3) Fertilization, water and light management: Spray with fertilizer containing nitrogen, phosphorus and potassium ratio of 17:8:22, fertilizer concentration is 1000ppm, once every 2 weeks; use pH6.0 water for spraying, every Once every 4 days; artificial shading is adopted, and the sunshade net is used in conjunction with it, and the light transmittance is controlled to 40% every day.

Embodiment 2

[0025] Management method:

[0026] (1) Plant selection and treatment: select a healthy air pineapple plant (Striket), cut off the dead leaves and broken leaves around the plant, and place it in the greenhouse to recover for 15 days;

[0027] (2) Soaking in solution: put the plant obtained in step (1) into Cu 2+ The concentration is 150mg / L copper sulfate aqueous solution soaks 20min, then takes out, cultivates under the outdoor natural low temperature state;

[0028] (3) Fertilization, water and light management: Spray with fertilizer containing nitrogen, phosphorus and potassium ratio of 17:8:22, fertilizer concentration is 1000ppm, once every 2 weeks; use pH7.0 water for spraying, every Once every 4 days; artificial shading is used, and the sunshade net is used in conjunction with it, and the light transmittance is controlled at 60% every day.

Embodiment 3

[0030] Management method:

[0031] (1) Plant selection and treatment: select a healthy air pineapple plant (velutina), cut off the dead leaves and broken leaves around the plant, and place it in the greenhouse for recovery for 15 days;

[0032] (2) Soaking in solution: put the plant obtained in step (1) into Cu 2+ The concentration is 125mg / L copper sulfate aqueous solution immersion 30min, then take out, cultivate under natural low temperature state outside;

[0033] (3) Fertilization, water and light management: use fertilizer containing nitrogen, phosphorus and potassium ratio of 17:8:22 for spraying, fertilizer concentration is 1000ppm, once every 2 weeks; use pH6.5 water for spraying, every Once every 4 days; artificial shading is used, and the sunshade net is used in conjunction with it, and the light transmittance is controlled to 50% every day.

Abstract

The invention discloses a management method for improving cold tolerance of tillandsia through copper. The method includes the following steps of plant selection and treatment; 2, solution soaking; 3, fertilization and water and illumination management. Compared with the prior art, by means of the method, the relative electric conductivity of tillandsia leaves can be remarkably reduced, the green holding period of the tillandsia leaves is remarkably prolonged, and the cold tolerance of tillandsia can be effectively improved.

Description

technical field [0001] The invention relates to a management method for improving the cold resistance of air pineapple by utilizing copper element, and belongs to the technical field of plant management. Background technique [0002] Air pineapple (scientific name Tillandsia, English name Air plant) is a perennial herb of Bromeliaceae (Tillandsia), including nearly 550 varieties and 90 varieties, with a wide variety and different shapes. my country has only begun to introduce this plant in recent years. Because of the unique characteristics of the terrier pineapple plant (grows in the air, does not need soil for cultivation, and has the characteristics of absorbing harmful substances such as formaldehyde and heavy metals), it has been loved and concerned by many people once it was introduced. [0003] At present, the research on air pineapple in my country is still in the preliminary stage, the cultivation technology is immature, and the variety is poor in cold resistance, ...
