Problems solved by technology

However, because most lotus species can only be planted in shallow water areas, most of the lotus species sold in the market can withstand water depths of 0.8 to 1 meter, and there are almost no deep-water varieties that can withstand water depths of more than 1.5 meters, because the water is too deep, and the lotus leaves will be submerged , Lost respiratory function, unable to carry out photosynthesis, so drowned, the deepest water level known to grow lotus is a kind of lotus in Puzhehei Scenic Area, Qiubei County, Yunnan Province, which can still grow in 3.2 meters deep water
This restricts the application of lotus in other aspects to a considerable extent, especially in the treatment of deep lakes or canals.

Embodiment 1

[0029] A kind of deep-water lotus breeding method of the present embodiment comprises steps as follows:

[0030] 1) Site selection: choose a place with strong light, good ventilation, sufficient water source, no buildings or trees to shade, and good water quality to build a pond as the experimental site. It is flat and can be built with concrete after using stone as a primer. In addition, each zone has an independent inlet and outlet to control the water level.

[0031] 2) Matrix preparation: prepare the matrix for lotus planting, which includes the following components in parts by weight: 80-100 parts of decomposed pond mud, 40-50 parts of garden soil, 10-50 parts of rapeseed cake 15 parts, 0-5 parts of bean cake fertilizer. After mixing the components evenly, they are divided into large pots with a diameter of 67 cm and a height of 50 cm, which are used as substrates for planting lotus flowers. The lotus vat can be made of ceramic vat produced in Yixing. The new vat shoul...

Embodiment 2

[0047] In this embodiment, the deep-water lotus bred by the method in Embodiment 1 is planted in ponds or lakes with a water depth of 2.5-3.0 to improve water quality and restore the ecological environment.

[0048] The variety numbered 20 selected and bred in Example 1 was bred and planted in a river pond with a water depth of 1.2-3.4m. After one year, the survival rate of the lotus was 80%, which had a good effect on improving the environment and restoring the ecology. The role of the environment, to achieve economic and environmental benefits.

Abstract

The invention discloses a method for selective breeding of deepwater nelumbo nucifera and a method for use of the deepwater nelumbo nucifera in ecological restoration. A deepwater-resistant variety isscreened out through controlling a planting water level of nelumbo nucifera; and the method is simple and reliable, limitations of shallow-water planting of the nelumbo nucifera are broken through, and thus, popularization of the deepwater nelumbo nucifera is facilitated. According to the method, the selective-bred nelumbo nucifera variety is further applied to ecological restoration engineering,and thus, the utilization ratio of deep water can be increased while deep water purification and ecological beautification are facilitated; and income is increased through harvesting lotus roots andlotus seeds, and thus, economic and environmental dual benefits are achieved.

Description

technical field [0001] The invention relates to a deep-water lotus breeding method and its ecological restoration method. [0002] technical background [0003] Lotus (Nelumbo nucifera Gaertn) is a perennial large-scale emergent plant of the genus Lily in the family Nymphaeaceae, also known as lotus or lotus. It is native to my country and is also one of the ten traditional famous flowers in my country. It faces the scorching sun without fear, has high ornamental value and economic value, and is deeply loved by people, so it is also widely used in gardening practice. However, because most lotus species can only be planted in shallow water areas, most of the lotus species sold in the market can withstand water depths of 0.8 to 1 meter, and there are almost no deep-water varieties that can withstand water depths of more than 1.5 meters, because the water is too deep, and the lotus leaves will be submerged , Lost respiratory function, unable to carry out photosynthesis, so drow...
