The whole city began to prevent insects and reminded the public not to eat the elm tree money again

The garden department is engaged in insecticidal operations.

As the temperature in the ice city warms up and the green shade grows thicker, a string of tender green and attractive elm tree money hangs on the branches, becoming a landscape of the city, and some citizens regard it as a plate of Chinese food, folding branches and making elm purse buns. Garden experts remind that this move has many hazards and must not be blindly picked.

Wrap buns with elm money? Don't eat!

Yesterday, in the Nine Stations Park in Harbin City, two elderly people carried a pocket and one took a cane to cooperate in collecting elm tree money. One person used a crutch to hook the full branches of the elm tree money on the higher place and dragged it down, and the other took the branch and swept it with his hand, and even the elm money with the leaves went into the pocket, leaving only a bare branch. In less than 20 minutes, a non-woven bag was bulging. "I guess I can pack a bun!" After exchanging a few words, the two walked out of the park.

An aunt who practiced in the morning told reporters that in the past week, there were people who came to collect elm tree money from time to time on the riverside, and the park management staff would stop it when they saw it, but most of the persuasion was ineffective, and if they did not let it be here, they would change places, after all, there were elm trees everywhere in the street.

Can the elm money of the green tree be eaten? How does the act of picking up elms affect trees? Wang Yinghong, director of the Harbin Garden Animal and Plant Quarantine Station, said that the act of greening the elm tree Qian'er first is an uncivilized behavior, which not only destroys the urban environment, but also seriously affects the growth of trees. The most critical thing is that green trees will spray drugs in order to prevent insects, although insecticides have tended to be less toxic in recent years, but eating them will still cause harm to the body. Moreover, the green trees in the city have been exposed to car exhaust for a long time, and heavy metals exceed the standard, which is not suitable for consumption.

The whole city kills elm purple leaf beetles, sky curtain caterpillars, and peach tumor aphids

The temperature is rising, and it is precisely because of the prosperity of various garden plants that diseases and insect pests of garden plants have also begun to occur. According to the climatic characteristics and the occurrence of diseases and insect pests, the Harbin Garden Animal and Plant Quarantine Station carried out unified pest control in all districts of the city yesterday on the basis of the universal spraying of stone sulfur compounds and the physical control of lychee purple leaf beetles.

At about 6 o'clock yesterday, the garden department of Nangang District of Harbin City dispatched 6 operating vehicles to prevent insects and kill the green trees on Hasi Yichun Road. The Municipal Garden Office and the Municipal Garden Animal and Plant Quarantine Station carried out the whole process of tracking services, technical guidance and supervision and inspection of the unified defense work.

Yuan Fenglian, director of the Nangang District Landscaping Management and Protection Center, told reporters that from April to October every year, the city's garden department will organize 6 large-scale anti-insect killings in the city, which belongs to the second batch of large-scale operations, and in addition to the unified action, the districts will also carry out insecticidal operations in batches according to the actual situation. In addition, every rain will wash away the insect-proof drugs on the green trees, if not sprinkled in time, until the pests multiply widely, the plants will be greatly damaged.

The staff said that the elm purple leaf beetle is the earliest pest recovered every year, and the main object of control this time is the elm purple leaf beetle, the elm green hair firefly leaf beetle, the canopy caterpillar that harms plum, apricot tree, mountain pear and other fruit trees, and the peach tumor aphid that harms the elm leaf plum. At the same time, for new trees and weak trees, rooting agents, flush fertilization, and slow-release fertilizer of seedlings are used for rejuvenation.

In order not to affect the normal life of the citizens, the garden staff in all districts of Harbin City chose to start operations in the early morning, and dispatched spraying equipment such as water wheels, aerial work vehicles and small spraying vehicles.
