Northern region lawn 9-10 months maintenance monthly calendar

With the arrival of autumn, the temperature gradually decreases. At this time, the cold-season lawn in the northern region will begin to enter the second growing season of the year, while the growth of the warm-season lawn will be nearing the end. The significance of lawn maintenance in this period is of great significance, and the quality of lawn maintenance in autumn not only directly affects the green period, quality and wintering ability of the lawn, but also affects the speed of greening in the second year of the lawn. Therefore, it is particularly important to do a good job in the daily maintenance of the lawn in autumn.

September

The average monthly temperature is 20.5 °C, the ground temperature is 22 °C (the temperature continues to drop, the lawn disease is reduced, it is in the recovery period, this month is the best growing season for cold season lawn grass, the management work is mainly to control pests, proper pruning, and fertilizer application).

1. The temperature gradually drops, and the pests on the lawn ground (twill nocturnal moth, slugs, slugs, etc.) begin to be active, and should be found in time and prevented in time. It can be used to control various aboveground pests with "Rick 1000 times + 3000 times lek, 400 times jin meiwei + 3000 times lek"; use "Dangong + make it / ground killing" to control underground pests (such as grubs, slugs, etc.), which can achieve the purpose of both killing insects and replenishing fertilizer.

2. The lawn disease has been significantly reduced in September, and the focus of work at this time is to promote the recovery of the lawn and continue to control the lawn disease. Every 7-10 days or after the rain can be controlled by green killing 500 times liquid, and the concentration of the disease spots is appropriately increased, and the focus is on spraying. At the same time, to do a good job in the prevention and control of powdery mildew and rust, it can be controlled by "Jingmu 1500-2000 times or Jingcui 1500-2000 times + 20% Guoguang triazolidone 1000 times". Dead spots should be removed in time, and replanting can be carried out for larger bald spots that appear in the lawn.

3. Recovery of diseased grass: Grass with weak growth after the onset of the disease can be used "garden power 1000 times + root pan 2500 times + Yuyang compound nitrophenol sodium 3000 times" with "Yuyang fertilizer 30g /㎡use, has a good effect on the recovery of lawn, continuous use of 2-3 times the best effect.

4. Watering: Water thoroughly to promote the rapid recovery of the lawn.

5． Pruning: Timely pruning, pruned grass clippings should be removed in time, while stubble returned to the previous normal growth height.

6． Fertilization: Cold season lawn is in the second growth period of the year at this time, fertilization with fast-acting high nitrogen compound fertilizer (such as Guoguang Yuyang fertilizer) with high potassium fertilizer (such as plain green) spraying, to meet the needs of lawn growth, while enhancing lawn stress resistance, promote the development of lawn grass root system, but also combined with punching weed and other operations.

October

The average monthly temperature is 15.5 °C, and the ground temperature is 16 °C (the temperature reaches the ideal temperature for cold season lawn growth, and the lawn is more ornamental).

1． The regular pruning work is basically completed at the beginning of this month, and the height of the lawn stubble should be appropriately increased to facilitate the normal overwintering of the lawn grass.

2． Lawn repairs and new lawns should be completed at the beginning of the month.

3． The number of watering can be appropriately reduced.

4． Increase the application of potassium fertilizer, promote lawn growth and leaf ripening, prolong the growth period, you can use "root hope 1500 times + flower thinking 600 times + green 600 times".

5. In areas with early winter, about 10 days before the yellowing period of the lawn, you can also cooperate with the application of "Yuyang" compound fertilizer 30g/m2 (watering immediately after fertilization), and spray "Lai lu shi dissolved fertilizer" 500 times + "Shi Qi" 5000 times, which can extend the green period of the lawn and postpone the yellowing.

The application effect of the products in this paper is affected by various factors such as lawn varieties, plant growth, climatic conditions and maintenance levels, and needs to be combined with reality and scientific use.
