Most lawns have returned to green, and excessive trampling of lawns should be prevented. 2. A large number of broad-leaved weeds can be controlled with 2.4-D butanone and other herbicides. Herbicides should be used strictly in accordance with the instructions, and repeated once every 10 days or so. 3. The pruning can be done properly in the late period, leaving a height of about 5 cm. 4. The area where insects are infested can be controlled by carbofuran or chrysanthemum lipids. May 1. When the lawn enters a vigorous growth period, the grass should be cut every 10 days or so. The height of the remaining ridge can be controlled to about 3-5 cm depending on the characteristics of different breeds. 2. Timely irrigation, and appropriate application of diammonium phosphate to promote turf growth. 3. In the later days, it is possible to prevent diseases that may occur in lawns. Carbendazim and triadimefon are sprayed every 10 days or so to prevent the occurrence of rust and spring dead spot disease. June 1. The lawn is gradually undergoing summer maintenance management. The lawn should be regularly trimmed to keep the blade sharp. Trim height should be higher, usually about 6 cm. 2. After each pruning, pesticides should be sprayed in time to prevent infection. The main pesticides are carbendazim, mancozeb, thiophanate-methyl and others. 3. Potassium fertilizer should be the main fertilizer, avoid the use of nitrogen fertilizer, fertilization amount of 15 grams / square meter as the standard. 4. Watering should avoid the high temperature time, try to water in the morning, taboo surface water. July-August From 1.7 to August, the weather in North China is hot and rainy, which is the season of cold-season turf disease. The maintenance and management work is mainly to control diseases.

Most of them are based on manual removal. 3. The occurrence of turfgrass disease is mostly caused by high temperature and high humidity. Therefore, the main watering should be selected in the morning, and control the amount of watering, which is expressed in wetness of 15-20 cm. 4. When pruning the lawn, avoid cutting too much. You should follow the "cut 1/3" principle. Cut 1/3 of the grass height each time. When the disease occurs, mowing the lawn should disinfect the blade of the mower. Prevent the spread of diseases.

The main drugs used are carbofuran, carbaryl, and enemies. 2. The turfgrass disease basically no longer spreads, and the dead spots should be promptly removed. For the bald spots that appear in the lawn, replanting work can be performed. 3. Phosphorus fertilizer is mainly applied to the lawn, and a small amount of potash fertilizer can be applied to enhance its resistance to disease and promote the development of turfgrass root system. 4. This month is the best time for the establishment of a cool season turf. The turf roll production and greening projects should be carried out mainly this month. October 1.
