Embodiment Construction
[0014] (1) Breeding environment and goals. The breeding environment is carried out in Hebei, Henan, Beijing, Jiangxi, Hunan and Hubei; and it is suitable for our country, especially suitable for planting in the above-mentioned areas, and has strong drought resistance, full corolla, and thick stems and varieties with good disease resistance.
[0015] (2) The selection of the hybrid parent, the parent adopts the wild rock weeping grass grown in the Japanese islands, and the female parent has a full corolla and a strong branch stem from mid-June to mid-October. The wild rock weeping grass grown in the Japanese islands has the advantages of full corolla and strong branches, but it is not resistant to disease and drought. Use the wild chrysanthemum in Ji'an and Jiangyan areas of Jiangxi Province of my country as the male parent with strong drought resistance and adaptability to carry out cross breeding; advantage. Reasonably configure the hybrid combination so that the advantages ...

Abstract
The invention belongs to a breeding method of a drought resistant lippia nodiflora. The breeding environment is selected in the regions of Hebei, Henan, Beijing, Jiangxi, Hunan and Hubei. The fry parent selects the wild lippia nodiflora grown in Japanese Islands with plump corollas and stick and strong stem between the mid June and the mid October as the female parent and the wild lippia nodiflora grown in Ji'an and Jiangyan areas in Jiangxi Province of our country with high drought resistance and adaptability as the male parent and crossbreeding. The lippia nodiflora bred by the method can greatly improve the quality of the lippia nodiflora and has the advantages of high drought resistance, large coverage area and increased soil phosphate fertilizer content by the residual body without virus diseases.
Description
technical field [0001] The invention belongs to a method for cultivating drought-resistant rock weeping grass. Background technique [0002] Phyla nadiflora (L.) Greene, scientific name: Phyla nadiflora (L.) Greene, perennial herbaceous plant, belongs to Verbenaceae, also known as: amaranthus, duck tongue Huang, duck bill Huang, duck tongue grass, Guojianglong, Guojiangteng. Rock weeping grass is widely distributed in warm regions all over the world, and often grows in humid places such as plains, mountains, and river beaches at an altitude of 300 to 2,300 meters. my country's rock weeping grass is distributed in Jiangsu, Jiangxi, Hubei, Hunan, Fujian, Taiwan, Guangdong, Sichuan, Guizhou, Yunnan and Tibet. The whole plant is covered with short hairs, the stems are slender, and the branches are prostrate on the sand or rocks, and the spread can reach 1-2m. Simple leaves, opposite, with short stalks, upper part of leaves with thick serrate margin, base narrowly cuneate, abou...
