Non-viviparous tropical water lily living plant division propagation method

Abstract

The invention provides a non-viviparous tropical water lily living plant division propagation method which comprises the following steps: equally dividing the whole screened non-viviparous tropical water lily into 2-4 blocks from roots from August to September every year, and ensuring that each division at least comprises more than one healthy leaf bud point and a plurality of mature leaves; thenplanting the divisions after plant division in a submerged potted planting mode, planting one division in each pot, keeping leaf bud points flush with a planting soil surface, keeping a water level higher than the leaf bud points at 5-10cm in an early stage, and gradually increasing the water level by 15-40cm in a later stage. The non-viviparous tropical water lily plants subjected to living plantdivision rapidly recover growth and can normally grow and bloom after 1-2 months, and the plants subjected to plant division retain the flower color and characters of the original plants and have high economic value and ornamental value; and the segmented non-viviparous tropical water lily can be subjected to division propagation again under the permission of environmental conditions, so that thepropagation rate is further increased, and the seedling propagation cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of seedling breeding in ornamental horticulture, and relates to a living ramet propagation method of non-viviparous tropical water lilies. Background technique [0002] Water lily is the general name of plants of the genus Nymphaea L. in the family Nymphaeaceae. It is a perennial aquatic herbaceous flower. According to ecological characteristics, it can be divided into cold-resistant water lilies and tropical water lilies. Tropical water lily flowers are tall and straight, high above the water surface, and have a strong and fragrant aroma. They are excellent fresh-cut flower materials. The flowers can be made into tea, and the petioles and flower stalks are edible. [0003] Tropical water lilies are significantly better than cold-resistant water lilies in terms of flower color, leaf color, flowering performance and use, but the price of their seedlings is generally high, often hundreds of yuan or even thousa...

AI Technical Summary

Problems solved by technology

The most suitable growth temperature for non-viviparous tropical water lilies is 30°C to 35°C, so the biggest disadvantage of breeding by forming dormant bulbs is that the temperature and low-temperature treatment time required for each variety of non-viviparous tropical water lilies to form dormant bulbs vary. Not the same, difficult to control, high or low temperature can easily lead to necrosis of dormant bulbs, the success rate is low, and some non-viviparous tropical water lilies are directly frozen to death at low temperatures and do not form dormant bulbs
