Water lily flower promoting cultivation method

Abstract

The invention discloses a water lily flower promoting cultivation method. The water lily flower promoting cultivation method comprises the following steps of (1) selecting a low-lying field or a shallow pond which is good in ventilation and illumination and has fertile soil, and carrying out irrigation after fertilizer is applied; (2) carrying out immersion and disinfection processing by using a 0.1% carbendazim solution after seed plants are selected; (3) planting tubers, maintaining the water depth at 20cm-30cm, and planting in a sparse mode; (4) maintaining the water depth at 60cm-70cm when water lilies enter an exuberant growing period, removing weeds in time, and meanwhile spraying a 0.3% copper sulfate solution on the water face; (5) maintaining the water depth at 75cm-80cm in a full-blossom period, and applying monopotassium phosphate paper parcels at the positions 10cm-15cm below rootstocks. By the adoption of the water lily flower promoting cultivation method, the full-blossom period of the flowering phase of the water lilies is made to be obvious, the water lilies are exuberant in growth vigor, the amount of flowering is large, the flowering phase is prolonged, leaves are thick and glossy, the flowers are large in flowering amount and deep in color, the disease resistance of the plants is enhanced, and ornamental effects are improved obviously.

Description

Technical field [0001] The invention relates to a cultivation method of ornamental flowers, in particular to a cultivation method for improving the flowering quality of water lilies, belonging to the technical field of ornamental flower cultivation. Background technique [0002] Water lily, also known as Ziwu lily, is a genus of Nymphaeaceae, which is distributed in subtropical and temperate regions. There are about 50 species in the world and 7 species in my country. According to their biological characteristics, they can be divided into cold-resistant water lilies and tropical water lilies.

Problems solved by technology

[0004] At present, there are problems such as how to improve the cultivation management level, effectively prevent and control diseases and insect pests, increase the number of flowers and prolong the flowering period in the cultivation process of the green plant water lily, but the lack of relevant cultivation technical measures greatly restricts the ornamental value of the water lily. How to increase the flowering number and prolong the flowering period of water lilies by means of cultivation techniques is an important issue facing water lilies as greening materials
