Embodiment 1

[0028] The implementation time of this embodiment is October 2017-November 2018, a kind of tropical water lily annual cultivation method suitable for subtropical regions, and its steps are:

[0029] Step 1. Prepare simple childcare facilities

[0030] Such as figure 1 As shown, select the watertight flowerpot 5 with a diameter of 40cm and a height of 45cm, and then fill the watertight flowerpot 5 with the cultivation matrix planting soil. When filling, at first fill the planting soil 3 with a thickness of about 1.5cm at the bottom of the pot. Sprinkle the total nutrient N+P evenly 2 o 5 +K 2 10g of nitrogen, phosphorus and potassium compound fertilizer with O content ≥ 51% and single nutrient content ≥ 17%, and finally fill the planting soil 3 to 2 / 3 of the flower pot, that is, the soil depth is about 30cm. 5:5 mixed to get.

[0031] Step 2. Colonization

[0032]Plant colonization was carried out on October 25, 2017, and strong ground-planted plants were selected in the ...

Embodiment 2

[0045] In November 2018-October 2019, implement the annual cultivation method of tropical water lilies suitable for subtropical regions in this embodiment, prepare simple conservation facilities, and carry out plant colonization on November 13, 2018. The specific operation method is the same as that of Example 1 Steps 1 and 2 are the same, and then enter the overwintering conservation stage. At this stage, the temperature management, ventilation management, and water level management methods are the same as in Example 1. The first and second stages were carried out on December 17, 2018 and February 27, 2019, respectively. Secondary fertilization, the fertilization method is the same as in Example 1, spraying 1500 times liquid of 10% beta-cypermethrin emulsifiable concentrate on December 28, 2018 and February 28, 2019 to prevent and control insect pests.

[0046] Finally, it entered the open-air cultivation display stage. The first flower appeared on April 9, 2019. The water lil...

Embodiment 3

[0048] In November 2018-October 2019, implement the annual cultivation method of tropical water lilies applicable to subtropical regions of this embodiment, and the specific steps are as follows:

[0049] Prepare simple conservation facilities, plant colonization on November 10, 2018, and select healthy tropical water lilies in the water lily display area to transplant to the greenhouse. The specific operation method is the same as in Example 1.

[0050] Then enter the overwintering conservation stage, wherein temperature management, nutrient management, water level management, management of diseases and insect pests are the same as embodiment 1, ventilation management, when the temperature in the simple and convenient conservation facilities is lower than 10 ℃, no ventilation, when the temperature in the simple and simple conservation facilities is 10 When the temperature is -20°C, ventilate for 30 minutes at 12:00 every day. When the temperature in the simple nursery facility...

Abstract

The invention discloses a tropical water lily year-round cultivation method applicable to a subtropical region. According to the method, tropical water lilies are overwintered by a simple conservationand fertilization mode in an auxiliary manner, tropical water lily plants are pretreated, temperature, nutrients, ventilation, water level and the like are managed during overwintering conservation,overwintering obstacles of the tropical water lilies are solved, and subterraneous stem rotting and plant floating of the tropical water lilies are remarkably improved. According to the cultivation method, the tropical water lily plants are cultivated in independent small flowerpots, the flowerpots are placed on the ground far away from water, spaces are remarkably saved, the growth speed of the plants is more easily controlled, growing environment conditions are most economically, effectively, simply and easily controlled, slow growth of the tropical water lilies can be ensured, the tropicalwater lilies cannot enter a dormant period, year-round and multi-year cultivation of the tropical water lilies in the subtropical region is easily achieved, and the method can be applicable to varioustropical water lily varieties and has excellent generalization performance.

Description

technical field [0001] The invention relates to the technical field of ornamental plant cultivation. More specifically, the present invention relates to a method for annual cultivation of tropical water lilies suitable for subtropical regions. Background technique [0002] Water lily is a general designation for plants of the genus Nymphaea in the family Nymphaeaceae, and belongs to perennial aquatic herbaceous plants. Its flowers and leaves are beautiful and highly ornamental, and it is one of the indispensable plant landscaping materials in waterscape gardens. And its flowers are edible and medicinal, and it is also a first-class fresh cut flower material. There are more than 60 original species and more than 1,000 cultivated varieties. In terms of plant taxonomy, Nymphaea is divided into 5 subgenera: Brachyceras, Lotos, Hydrocallis, Anecphya and Anecphya. Temperate subgenus (Nymphaea). According to its ecological type, it can be divided into tropical waterlily and ha...
