As the weather turns cold, plant growth enters a dormant phase, and many diseases and insect pests that harm plants will also enter the wintering period.
Today, the Xi'an Municipal Gardens Bureau has issued plant protection information to various gardening and conservation departments in the city, and it is required to use this period to carry out prevention and control of overwintering pests and diseases in garden trees. For the trees, flowers and plants that grow in the community and courtyard, the City and Gardens Bureau also gives points on pest control in the information.
One is to trim in time. Through pruning, the trees can be ventilated and lighted, which can promote the balance of moisture and nutrients, and directly reduce the occurrence of pests. In addition, timely pruning of dead branches, split branches and broken branches of the trees is performed. The second is fertilization irrigation. Through strengthening the fertilization of plants to increase the overwintering ability of trees and improve their resistance to diseases and insect pests, irrigation at the beginning of autumn and early winter can promote the absorption of nutrients from the roots and improve the safety of the trees overwintering. The third is the Pharmacy Clear Garden. Because many pests spend their winters on the branches and leaves, spraying Baume 3 to 5 degrees lime sulfur plus 200 times pentachlorophenol sodium after defoliating the trees to germinate can eliminate the overwintering pests and various eggs, so as to reduce the disease in the coming year. Occurrence of insects.
In addition, the Municipal Gardens Bureau also reminded to do a good job in winter frost protection of trees and flowers: a parcel. Wrapped in plastic paper or wrapped in straw, it can also be wrapped with straw rope to prevent freezing damage to the plants. Second set the wind barrier. In some areas, the wind is extremely windy and the wind speed is particularly high, which can easily cause freezing damage to some plants and flowers. It is necessary to set up barriers in the windy areas to block the strong winds and reduce the damage to plants. Three trunk brush white paint. It can prevent frostbite, sunburn, insect injury and infection of the trunk. Four spray antifreeze. Some precious plants can be sprayed with 10% PolyU antifreeze, and other plant antifreeze can also be used.
Laser distance measure is a very convenient tool for various types of applications in industries, construction and house decoration. Laser distance meter is a very useful device which gives accurate measurement of distance, area and volume especially in large areas such as rooms, apartments, buildings, real estates, factories, warehouses, infrastructures, gardens, roads, and many other applications requiring accurate results for distance , area and volume measurement.
Trade your heavy tape measure for laser
rangefinder, which let you simply take measurements with one hand. No matter
your job, the laser rangefinder will help you measure much farther, with
greater accuracy and in more situations, saving you money and time.
