Just after Lixia, the temperature difference between day and night in the north was large, and the precipitation was uneven, which had a great impact on agricultural production. As the precipitation begins to increase, on the one hand, the fruit trees can be “drinked†beautifully, however, continuous rainfall will also have a certain impact on cherry, peach and other fruit trees.
The heavy rain caused the cherry to crack the fruit. At present, the open field cherry has entered the final ripening stage, and it is expected to be picked in the next week. However, judging from the recent weather, there is a lot of rain. For the management of cherries in the near future, we must pay attention to the problem of precipitation. At this time, a large amount of precipitation will cause open-field cherry cracking, which has little effect on the cherries in the greenhouse. Only need to control the temperature and humidity in the shed. Prevent breeding of diseases and insects.
Pest control in the peach production area is urgent. It is understood that since this year, the peach aphid has spread in many areas, and even in the northern peach production area, the severely infested areas have caused peach trees to die, and farmers have suffered great losses.
Experts suggest that fruit tree aphids are always based on prevention, and early application is the best policy. It is necessary to spray Baume 5 degree lime sulfur mixture before the flowering period of peach tree; after flowering period, you can use avermectin or imidacloprid for spraying according to the instructions, and add a small amount of washing powder to the liquid to increase the drug Adhesion, leaving the drug on the leaf surface for a long time, prolonging the effect.
