Fungicides control brown spot After fruit bagging, it entered the high temperature and rainy season, and apple brown spot disease entered a period of high incidence. The prevention and treatment of brown spot in apple should be strengthened to prevent early defoliation. Organic fungicides can be used interchangeably with Bordeaux mixture. Generally, at least two times of Bordeaux mixture should be sprayed. Organic fungicides can be used: 4000% of tebuconazole 43%, 2000 times of 10% difenoconazole, 800 times 80% of mancozeb. Investigate pest control in time After the bagging, there are mainly red spiders, white spiders, aphids, leaf leaf moths, and fruit borers. Special attention should be paid to the control of red and white spiders. In hot weather, red and white spiders have shorter breeding cycles and increased egg production. If the control effect is not good in the early stages, it will easily break out in the later period. Red and white spiders will lose their photosynthetic capacity and cause premature defoliation. Therefore, attention should be paid to the investigation of insect pests in time. . The agent can be used with 1.8% avermectin 4,000 times, 15% lingzhi 1500 times, and 25% triazotin 2,000 times. Pay attention to control the new shoot The new shooter Wangchang not only competes for nutrients with the fruit, but also tends to cause canopy closure, affecting ventilation and light transmission, reducing fruit quality, and affecting flower bud differentiation. Weeding upright long branches and dense shoots on the back and picking up new shoots at the same time, the number of picking up must not exceed 20% of the middle shoots, in order to prevent stripping, and there is more than 40cm of space on the back. Stopping the new shoots and carrying out twisting tips to promote flowering. Phosphorus and Potassium Fertilizers by Time Top dressing is an effective measure to promote fruit enlargement. Mid-maturing varieties in mid-July, late-maturing varieties in late August, the main phosphorus and potassium fertilizers, trace elements and fertilizers. Potassium fertilizers mainly include potassium dihydrogen phosphate and potassium sulfate. Phosphorus and Potassium fertilizers are generally applied by spraying water or foliar spraying. The amount used is, for example, the full fruit period. Potassium dihydrogen phosphate or potassium sulfate 0.5 kg/plant is applied, and the concentration of potassium dihydrogen phosphate is 0.2%. . Drought irrigation row flexible management Under drought conditions, soil moisture decreases, roots do not grow normally and nutrients are absorbed, and fruit swelling is inhibited, and bitter pit disease and other deficiency traits can be induced. In the rainy season, in the case of locust damage, it will affect the normal development of the root system. It will also cause root anoxia and death. It will also affect the absorption of nutrients, fruit enlargement, and induction of deficiency syndrome. Watering the bagged apples 2-3 days before picking up the bag can prevent the fruit from burning day by day, change the microclimate conditions of the orchard, increase the temperature difference between day and night, and create night dew, which is conducive to fruit coloring. Therefore, the orchards need to use water-saving and water-saving measures such as micro-spraying, straw mulching, etc. to ensure that the drought can be poured and discharged.

Firstly, fresh and mature fruits with good quality were selected in the pre-treatment area of the food lyophilizer, and the leaves were removed to remove impurities. Then, preliminary cleaning and simultaneous sterilization of fruit surface were carried out. After sterilization, the fruits were cleaned and drained again. After the drain, the fruit is sliced and treated by blanching process. After the color preservation, the fruit is treated by pulping, and then pasteurized. The pretreatment process is finished before lyophilization.
The processing core of freeze-drying powder is the equipment area of food freeze-drying machine. After pre-treatment, the fruit enters the equipment of food freeze-drying machine and crystallizes into a solid state at low temperature, and then sublimates and dries in a vacuum environment to obtain freeze-drying products with little water content. Freeze-dried products out of the warehouse into the food freeze-dried post-processing area, ultrafine grinding, and then according to the need to do weighing packaging, after testing the finished products packed into storage.
Apple sets up bag management
After bagging apples, management still cannot be ignored. The focus of orchard management should be to protect the leaves, promote fruit enlargement, control the growth of new shoots, adjust the orchard's ventilation and ventilation, and regulate soil moisture management in orchards.
