Problems solved by technology

It is difficult to obtain seeds of Snakeberry Potentilla, and root propagation is the most widely used propagation method in production at present, but the disadvantage is that the propagation coefficient is low, which limits the propagation speed and increases the propagation cost

Embodiment 1

[0016] (1) Determine the planting period: the stolon on the mother plant of Snakeberry Potentilla grows to more than 30 centimeters, and when there are 4 stem nodes on the stem, the planting work begins;

[0017] (2) select stolon: select the stolon that grows vigorously, have 4 and more than 4 stem nodes, two stolons on every strain do not cut off, keep two stolons to be connected by mother plant root system;

[0018] (3) Soil preparation: fine-tune and rake the soil to remove weeds;

[0019] (4) Ditching and irrigation: open a 5 cm deep ditch, the distance between the ditch and the ditch is 30 cm, and then irrigate in the ditch;

[0020] (5) Cutting and embedding strips: After the water in the ditch has penetrated clean, place the selected stolons horizontally in the ditch, cover with 1-2 cm thick fine soil, and expose the leaves on each stem node to the outside of the soil;

[0021] (6) Covering and shading: After the cutting and embedding work is completed, cover it with ...

Abstract

The invention relates to a method for planting green lawn for landscaping, slope protection of roads and courtyard landscape, in particular to a method for planting green lawn by using stolons of Potentilla centigrana Maxim. In the plantation period, the stolons with at least four stalk nodes are selected, and every two stolons on each plant are not cut and are connected through a mother plant root system. The method comprises the following steps of: preparing soil; ditching and watering; completely permeating water in the ditch, horizontally putting the selected stolons into the ditch, covering fine soil with the thickness of 1 to 2 cm, and making leaves on each stalk node exposed out of the soil; finishing the work of cuttage and stem burying, covering by using a shading net; performing field management, removing the shading net after new roots and leaves are grown; and forming the newly planted lawn within 40 to 50 days. The reproduction coefficient of the Potentilla centigrana Maxim is improved by 16 times compared with that of the traditional method, seedlings are greatly saved, the shortage of the seedlings is relieved and the reproduction cost is reduced.

Description

technical field [0001] The invention relates to a method for building a green lawn for landscaping, road slope protection and courtyard landscape, in particular to a method for building a green lawn with stolons of Potentilla chinensis. technical background [0002] Potentilla centigrana Maxim. is a perennial herb belonging to Potentilla centigrana Maxim. It is tolerant to shade and waterlogging, and has strong adaptability. It grows in forests, meadows, roadside wetlands, etc. In Liaoning, it is mainly produced in Xifeng, Qingyuan, Kaiyuan and Benxi counties. Widely distributed in Northeast, North and Southwest China. The roots of Snakeberry Potentilla are fibrous; the stems are thin and weak, often rooting at the nodes, 30-70 cm long; palmate three compound leaves, the stipules are large, ovate, the leaflets are thin, and the edges are serrated; the flowers are solitary in the leaf axils, 0.8 cm in diameter, 5 petals, yellow, flowering period from June to July. Snakebe...
