Method for improving growth performance of lawn plants by adopting rare earth lanthanum

Abstract

The invention relates to a method for improving growth performance of lawn plants by adopting rare earth lanthanum. The method comprises the following steps of: soaking seeds of lawn plants with lanthanum nitrate water solution at a concentration of 50mg.L<-1>-300mg.L<-1> for 18-24 hours; then sowing the seeds in a culture dish with filter paper spread, and putting the culture dish with the sowed seeds in the sun to germinate the seeds; beginning recording the germination number 2-3 days after sowing the seeds; and after grass seed growth ends, cutting off the plants at ground level with scissors, measuring the fresh weight of the single plant and the total fresh weight, drying the samples in a drying box at 80 DEG C for 8 hours, and measuring each index. Adopted to soak the seeds, the rare earth lanthanum has an influence on germination and initial growth of Lolium perenne L. and Festuca arundinacea.L, has an effect on promoting germination of the two grass seeds, and has an obvious effect on promoting growth of the underground root system parts. Therefore, the research results show that the rooting degrees and green degrees of the grass seeds on the lawns are regulated to achieve the best effects by soaking the seeds with the rare earth element.

Description

technical field [0001] The invention relates to the application of the rare earth lanthanum in the technical field of urban lawn construction, in particular to a method for improving the growth performance of lawn plants by using the rare earth lanthanum, and the application in regulating the degree of rooting and greenness of lawn grass species. Background technique [0002] my country is extremely rich in rare earth resources. In recent years, some relevant research units and colleges in more than 20 domestic provinces and autonomous regions have also conducted research on the application of rare earths. Practice has proved. The use of rare earth elements can achieve the purpose of increasing crop yield by affecting the physiological and metabolic activities of agricultural field crops. [0003] Rare earth elements can promote the growth and development of field crops, increase yield, improve quality, and enhance the resistance to adverse conditions such as acid rain, dr...

Problems solved by technology

Lawn plants have weak root activity in the seedling stage, and the growth of the aboveground parts is slow, and the characteristics of weak early growth of lawn plants often make lawn plants in a disadvantaged position in the competition with weeds in the early stage of growth. Such results can lead to Lawn planting failure; in addition, under the environmental conditions of drought and water shortage, the phenomenon that lawn plants are at a disadvantage in the early stage of growth is particularly prominent in the competition with weeds; this directly affects the survival rate of lawn plants; The biggest difficulty in the application of planting in practice, that is, the problem of lawn planting experiencing technical "bottleneck" constraints
