Embodiment 1

[0023] Example 1 The method of cultivating pineapple with colorful leaves by supplementing light with ultraviolet lamps

[0024] 1) Preparation of seedlings: select seedlings with strong growth, wide and short leaves, and 6-month-old seedlings for use;

[0025] 2) Preparation of cultivation facilities: The cultivation facilities are plastic greenhouses, equipped with external sunshade and wet curtain fan cooling system, the sunshade rate of the sunshade net is 70%, and an ultraviolet supplementary light is installed 50cm above the plants, one 30W per square meter lights;

[0026] 3) Fertilizer preparation: preparation containing N:P 2 o 5 :K 2 O is the fertilizer of 5:10:20, spare;

[0027] Application: plant the seedlings of step 1) in the facility of step 2), and apply the fertilizer of step 3). Apply fertilizer every 2 weeks from June to July, dilute 1000 times with water and water the leaves. The lighting time is from 6:00 to 18:00 every day. See the effect figure...

Embodiment 2

[0028] Example 2 Cultivation of Coleus pineapple 1 by supplementing light with purple light lamp

[0029] In this example, step 2) the shading rate of the cultivation facility is 50%, and a purple light is used to supplement the light; step 3) the preparation containing N:P 2 o 5 :K 2 O is the fertilizer at 0:10:25; Step 4) The light supplement time is from 9 am to 5 pm every day. Fertilizer was applied every 2 weeks from June to October; all the other steps were the same as in Example 1. See the effect figure 1 . This example makes the leaves of Coleus pineapple show bright colors, the markings are clearer and brighter, and the ornamental value is better.

Embodiment 3

[0030] Example 3 Cultivation of Coleus pineapple with supplementary light in a simple greenhouse

[0031] In this example, step 2) chooses a mountainous area with a relatively cool summer, and the cultivation facility is a simple data greenhouse, and the film is directly covered with a sunshade net. N:P 2 o 5 :K 2 O is the fertilizer of 5:10:20; step 4) The light supplement time is from 18:00 to 6:00 the next day. All the other steps are the same as in Example 1.

Abstract

The invention discloses a method for controlled cultivating of neoregelia carolinae. The method comprises the following steps of: (1) preparation of seedlings; (2) preparation of cultivation facilities: arranging an external sunshade and a wet-curtain fan cooling system for a plastic greenhouse, or adopting a simple plastic greenhouse in a mountainous area, and covering the exterior of a plastic thin film directly with a sunshade net, wherein the sunshade rate of the sunshade net is 30-70%; and installing light supplementing lamps at a position 30-80cm above plants, wherein the power of the installed lamps per square meter is 20-30 W, and types of the lamps are selected from black light bulbs, ultraviolet lamps and red, blue and full-spectrum Led light-supplementing lamps; (3) preparationof fertilizer: wherein the fertilizer contains, by mass, 0-5% of N, 5-10% of P2O5 and 15-30% of K2O; and (4) application: keeping the light supplementing lamps on for 8-12 hours regularly every day from June to October, and applying the fertilizer once every 1-4 weeks. Through the method, the length of newly grown leaves of the neoregelia carolinae can be shortened effectively, the plant shape canbe improved, the leaves of the neoregelia carolinae can exhibit bright color, and stripes of the leaves are clearer and brighter, so that the ornamental value is better.
