In mid-June, 5438+10, the scale insects began to move, but at this time, they moved slowly, so we can take the method of scraping off the larvae on the trunk. Controlling pests in winter often gets twice the result with half the effort.

February: The temperature is higher than last month, and the trees are still dormant.

1, maintenance is basically the same as 1.

2. Pruning: Continue to prune dead branches and diseased branches of large and small trees. Prune all kinds of trees before the end of the month.

March: The temperature keeps rising. After the middle period, trees began to germinate, and some trees bloomed in the later period.

1, spring irrigation: due to the drought and windy in spring, the evaporation is large. In order to prevent the spring drought, the green land should be watered in time.

2. Fertilization: After the soil is thawed, apply base fertilizer to the plants and irrigate them.

3. Prevention and control of pests and diseases: This month is a critical moment to prevent and control pests and diseases. Some seedlings have black spot disease, and so does Euonymus japonicus. The method of digging pupae can continue to be used to control moths.

April: The temperature continues to rise, and trees sprout, bloom or spread their leaves into a vigorous growth period.

1, shrubs that died in winter should be pulled out and replanted in time, and new trees should be fully watered.

2. Irrigation: Continue to water the green land in time.

3. Fertilization: combined with lawn and shrub irrigation, topdressing with quick-acting nitrogen fertilizer, or foliar spraying as required. 4. Pruning: You can prune the evergreen hedge by cutting off dead branches in winter and spring.

May: The temperature rises sharply and trees grow rapidly.

1. Watering: During the tree exhibition in Ye Sheng, the water demand is very large, so water should be done in time.

2. Trim: Trim the residual flowers. Trees on the roadside were pruned for the first time.

The first generation of stickleback moth has hatched, but it has not reached the degree of harm, so the reserve should take corresponding measures according to the actual situation. Sooty blotch caused by scale insects and aphids. It has also entered the peak period (for crape myrtle, pittosporum, oleander, etc. ). In the middle and late May, spray turpentine mixed solution with the time of 10-20 and 50% dithionite emulsion with the time of 1500-2000 to prevent diseases and kill insects (other available pesticides, pesticides, pesticides, pesticides,

June: The temperature is high.

1, watering: plants need a lot of water, so they should be watered in time, instead of "eating with the weather".

July: The temperature is the highest, and there is strong wind and heavy rain after the middle.

1, transplant evergreen trees: in rainy season, there is enough water, but pay attention to the weather changes, and water them in time in case of high temperature.

4. Pest control: continue to control longicorn beetles and borers. We can use 50% cartap 1: 50 times solution to prevent and control the longicorn beetle (or guoshubao or Yuan Ke No.3), and then seal the hole, which can also achieve good results.

August: It's still rainy season.

1. Drainage: After heavy rain, low-lying accumulated water should be drained in time.

2. Fertilization: For some trees with weak growth and insufficient branches, some phosphorus and potassium fertilizers should be applied as topdressing.

3. Pest control: perforation is the peak, and 500% carbendazim 1000 times solution is used to control infection. Long-horned beetles began to turn to the roots for harm, so attention should be paid to catching the root beetles. Do a good job in the prevention and control of other pests and diseases.

65438+1October: The temperature drops, and1October enters the early winter, and the trees begin to shed their leaves and gradually enter the dormant period.
