Answer: Chang Zongtang, a consultant from the old Yangling Association for Science and Technology and a researcher at Northwest A&F University, responded: 1. Choose the planting period. According to the performance of one's own greenhouses, the length of the growth period of vegetable crops is to be scientifically determined to ensure that the crops have sufficient growth period. Prepare the land in advance for ridging, and apply sufficient decomposed organic fertilizer, bio-organic fertilizer and trace elements at the same time. 2. Choose suitable varieties. In autumn and winter, the temperature is gradually reduced, the light time is gradually shortened, and the humidity in the shed is high. The types and varieties that are resistant to low light and low temperature should be selected. 3. Cultivate robust seedlings. When planting, use the cultivation method of high-ridge mulching and drip irrigation under the film; appropriate sparse planting, not too high planting density, to reduce the occurrence of various diseases and insect pests. 4. Temperature and humidity management. The temperature environment most suitable for the growth and development of crops in the autumn greenhouse is generally 22～30℃ during the day, 15～22℃ at night, and the temperature difference between day and night is 8～10℃. Irrigation should be carried out according to the characteristics of water demand and soil moisture in different growth periods of crops, and at the same time, ventilation and moisture removal should be reasonable. After slowing the seedlings, cultivate the soil to loosen the soil and control the water to squat the seedlings to prevent the crop roots from suffocating or retting the roots due to lack of oxygen due to soil moisture. 5. Light management. Greenhouses with serious aging film should be replaced before planting. Frequently clean the shed film shade to ensure the amount of light in the shed. 6. Disease and pest control. During the summer fallow period, the high temperature and stuffy shed are carried out, and the planted seedlings are treated with medicine to prevent diseases. Autumn is a period of high incidence of various diseases and insect pests. Pay attention to the prevention and control of diseases and insect pests. Biological control (releasing natural enemies, etc.), agricultural control (planting and cultivation management, etc.), physical control (hanging yellow sticky oil boards, black lights, etc.), chemical control and other methods can be used for prevention and control. Fruit juice drinks is a beverage made of fruit juice products obtained by physical methods such as pressing, centrifugation and extraction. Fruit juice retains most of the nutrients in the fruit, such as vitamins, minerals, sugar and pectin in dietary fiber. Often drinking fruit juice can help digestion, moisten the intestines and supplement the lack of nutrients in the diet.

There are two kinds of fruit juice: pure fruit juice and compound fruit juice. As far as pure fruit juice is concerned, it can be divided into two types: one is to directly use the original juice, and the other is to dehydrate the freshly squeezed fruit juice first, and then add water to reduce it into concentrated fruit juice. Most pure fruit juices are concentrated. AGOLYN offers various flavors of honey tea, such as honey Citron tea etc.
