The invention provides a cultivation method for lawns of a sloping field type coastal heavy saline-alkali land. The cultivation method comprises the following steps of laying a salt discharge system, laying an irrigation system, carrying out raw soil preparation, planting festuca arundinacea, planting zoysia matrella, planting perennial ryegrass and carrying out planting post-management. The step of laying the salt discharge system comprises the following steps: digging salt discharge ditches properly along the altitude direction of a sloping field from the top of the sloping field to the base part of the sloping field, wherein the salt discharge ditches are 1m to 1.2m in depth; and laying salt discharge underground pipes in the ditches according to a principle that one pipe is arranged in one ditch. The step of laying the irrigation system comprises the following steps: laying the irrigation system at a position which is 75cm to 80cm in depth below the ground surface, wherein the laying space of irrigation water pipes is 5m; setting up one water spraying pipe every other 5m on each water pipe, wherein each water spraying pipe can extend to be a part which is 15cm to 20cm above the ground surface and a spraying nozzle capable of realizing 360-degree water spraying is mounted at a pipe opening of each water spraying pipe. The cultivation method for the lawns of the saline-alkali land, provided by the invention, has the advantages of rapid lawn formation speed, high lawn survival rate and uneasiness of degradation.

The isolation and function of a plant LpTFL1 from Lolium perenne (perennial ryegrass) are described, along with generation of transgenic Arabidopsis ryegrass, and red fescue plants. Thc gene prevents or represses flowering of transgenic plants. Methods for using the gene to repress or prevent flowering are described.

The invention discloses a method for establishing perennial ryegrass genetic conversion receptor system through embryoid generation approach, which mainly consists of using perennial ryegrass' mature seeds as material, obtaining callus through medium induced culture, carrying out subculture, inducing embryoid and regenerated strains in callus induced medium and regenerated medium, charging 2,4-D,6-BA,NAA and hydrolyse casein CH of a predetermined proportion into the induced callus medium, so as to effectively increase the inductivity of the callus.

The invention is concerned with the application method that uses the straw and the lawn plant to recover the housing refuse with heavy metal, it is: the 10 to 80 of housing refuse compost mix with 1 to 10 of straw to make the lawn plant culture substrate, seeds on the lawn plant culture substrate and give water every day, uses the ICP-AES method to test the heavy metal content after distilling bythe lawn plant from cradle the upside of the lawn plant; the result shows with the paddy straw, the recover actuation of the Cr, Ni and Cd by the secular-grow ryegrass, and the recover actuation of the Cr and Ni by festuca arundinacea are big foreground.

Perennial ryegrass plants with a spreading habit are provided. The perennial ryegrass plants of the present invention display a growth habit with intertwining tillers that form a very dense sward of 10,000 tillers or more per square foot within one growing season. The ryegrass plants of the present invention also display secondary tillers, something not seen in currently available commercial perennial ryegrass varieties. The spreading growth habit of the plants of the present invention makes a very attractive turfgrass when grown for turf and also provides high seed production.
