Abstract

The invention provides a spring and autumn replacement method for overseeding lawns in middle and lower reaches of Yangtze River and application of the replacement method. The replacement method comprises the following steps of in spring, (1) trimming cold-season grass in the germination period of warm-season grass replacing watering water for the warm-season grass with a solution obtained by dissolving a plant growth regulator and a water-soluble organic fertilizer in water, infiltrating the solution into a warm-season grass root system through an infiltrating irrigation pipe; spraying a herbicide on the surface of the cold-season grass; performing watering and fertilizing through an infiltrating irrigation pipe; (2) performing normal maintenance after the warm-season grass turns green; in autumn, (1 ') mixing cold-season grass seeds soaked with a cell division agent with a compound microbial agent and an organic fertilizer, and sowing in October; spraying a cell division agent and a trace element fertilizer after the cold-season grass sprouts; performing watering and fertilizing by spraying on the surface of the lawn; (2 ') carrying out normal maintenance after the cold-season grass is formed into the lawn. According to the replacement method, the withering and yellowing time during replacement in spring and autumn can be effectively shortened, and the green period of the lawn is prolonged.

Description

technical field [0001] The invention belongs to the field of vegetation greening, in particular to a spring and autumn replacement method for overseeding lawns in the middle and lower reaches of the Yangtze River and its application, in particular to a spring and autumn replacement method for overseeding lawns in the middle and lower reaches of the Yangtze River with long lawn green periods and applications. Background technique [0002] The lawn overseeding maintenance technology has been widely used at home and abroad. In order to keep the lawn evergreen and not yellow, in the use of the overseeding technology, more researches have been done on the timely and appropriate application of maintenance methods. According to the local climate conditions in the area where the lawn is located, through Choose the right time and good varieties, as well as optimize and compare the maintenance methods such as pruning, fertilization, drilling, weeding, etc., and give the best time and o...
