Embodiment 1

[0037] A kind of cultivation method of promoting water lily to bloom in winter, comprising the following steps:

[0038] Step 1. Preparation before planting

[0039] In mid-September, use a non-porous nutrient bowl with a height of 50 cm and a diameter of 40 cm, and apply decomposed bean cake fertilizer or rapeseed cake as the base fertilizer; fill in the treated pond mud, and the thickness of the pond mud is controlled at 40 cm;

[0040] The pond mud treatment method is as follows: first expose the pond mud to the sun for 2 days to reduce the water content to 10%, then sprinkle water to make the water content of the pond mud 40%, and then spray 50% or 75% chlorothalonil wettable powder 800 times liquid, Or 80% mancozeb wettable powder 1000 times liquid;

[0041] Step 2. Selection, processing and planting of seed plants

[0042] Select virus-free, non-damaged tubers with strong terminal buds as seed plants, clean them, and spray 50% carbendazim wettable powder 800 times or 7...

Abstract

The present invention discloses a cultivation method for facilitating winter blooming of water lilies. The cultivation method comprises: (1) applying a base fertilizer into a nutrition bowl in middle and late September and filling the nutrition bowl with pond mud; (2) selecting tubers without viruses and damage and with terminal buds as seed plants; washing the seed plants and then carrying out disinfection treatment on the seed plants; (3) burying the disinfected seed plants into the central position of the nutrition bowl and enabling the terminal buds to be exposed out of the pond mud by 1-2cm; after transplanting the seed plants, immersing the seed plants into a water tank, and injecting water to flood the nutrition bowl by 0-5cm; (4) controlling a water-flooding depth: controlling the water-flooding depth to be 50-65cm at a seedling period, and controlling the water-flooding depth to be 95-115cm at a flower bud period; (5) at the flower bud period, keeping an indoor temperature to be 20-35 DEG C and keeping a water temperature to be 18-25 DEG C; at a blooming period, keeping the indoor temperature to be 20-30 DEG C, keeping the water temperature to be 15-25 DEG C, and controlling the indoor illumination intensity to be 1000-2500lux; and controlling the oxygen content of a water body to be 15-20mg / L. With the adoption of the cultivation method, the blooming quantity can be increased, the flowering phase of the water lilies is prolonged, the economic value of the water lilies is improved and market requirements are met.

Description

technical field [0001] The invention relates to a plant cultivation method, in particular to a cultivation method for promoting winter flowering of water lilies. Background technique [0002] Water lilies, Nymphaeaceae Nymphaea, are distributed in subtropical and temperate regions, and can be divided into cold-resistant water lilies and tropical water lilies according to their biological characteristics. Water lily is a perennial floating-leaf aquatic plant. Its flower diameter is large and its color is rich, so it is deeply loved by people. Under the natural phenological environment, most tropical water lilies and all hardy water lilies bloom during the day (7:00-15:00), while some tropical water lilies bloom at night (21:00 to 12:00 the next day). The flowering period of water lilies is mainly concentrated from May to September, and enters a dormant period after November, and the winter landscape cannot be displayed. At present, there is no effective cultivation method f...
