Recently, people have asked the author a lot of questions about the Qingyuan Garden. Among them, the most frequently asked question is what kind of medicine is better. What about using lime sulfur, and whether tetracycline, triazotin, and other acaricides are available at this time? . First of all, I think that the Qingyuan Garden is an important part of the prevention and control of pests and diseases in orchards. To do a good job in clearing the garden can reduce the number of bacterial sources and pests for wintering, and it will be very good for preventing and controlling pests and diseases. Qingyuan refers to the agricultural operation for the purpose of preventing pests and diseases before the flower bud red period, and mainly includes physical clearing gardens and chemical clearing gardens. The physical clearance includes the removal of dead fruits from the tree and the inclusion of worm-eaten leaf clusters; the combination of pruning removes diseased branches, lightly scrapes the skin, reduces the amount of pathogenic bacteria, removes fallen leaves, and places all kinds of residues on the trees. Buried or brought out of the garden. Care should be taken when cleaning the garden to scratch the skin instead of scraping the bark, otherwise the trunk is susceptible to injury or disease. After removing the dead branches in the clear garden, the wound healing agent should be immediately applied to the wound. We are not the same as the developed countries in the physical clean garden. In Europe, America, Australia and other countries, grass is very common in orchards, so there are few practices to clean the leaves. They often spray 5% urea on the leaves after fruit picking in the previous year. This can promote early leaf shedding and can Accelerates the decomposition of leaves in the soil. In Europe and the United States and other developed countries, there are few rots and ringholes in the apple trees. Therefore, the branches orchards pruned in the orchards are mostly crushed by machines and laid in rows to increase the soil organic matter. In our country, especially in the apple production area of ​​Bohai Bay, the disease of ringworm is very serious. The cut branches must be brought out of the garden, otherwise it will become the source of infection and increase the disease. Chemical clearing gardens refers to the measures to kill germs and pests by spraying chemical agents. Here I would like to tell everyone that it is difficult to achieve the eradication of germs and pests through chemical cleanup. At present, the major diseases of our apple orchards include rot, rotiferous ring rot disease, early defoliation and viral diseases. In the case of rot disease and rotiferous ring rot disease, as long as the tree has already developed, the bacterium is often already in the interior of the trunk, and only the chemical is sprayed once, and the internal bacteria cannot be removed. If we can play some role, it can only be reflected when rainfall occurs after spraying, because only when there is rain, the bacteria can be released from the deep inside to carry out new infections. Some protective bactericidal effect. It is worth noting that this effect is very limited. This is because the temperature in spring is still very low, and it is not a critical period for a large number of infestations of the ringworm pathogen. Moreover, in most of our fruit areas, there is very little rainfall in the spring. If there is no rainfall during the residual period of pesticides, then the pharmaceutical agents in Qingyuan will lose its effect. In the case of rot, germs can infect apple trees in the winter, but the infestation is mainly through saw cuts. Therefore, applying the wound immediately after pruning is the best measure for preserving rot. If you do not apply the medicine to the saw cuts, the germs will invade the inside of the host tissue. Even if chemicals are sprayed on the garden, it will not help. For early defoliation, the leaves have not yet grown on the tree in March. It is not possible to spray anti-early defoliation at this time. As for viral diseases, it is even a problem that cannot be solved by spraying. For pests, most of the pests are dormant in March and it is best not to use pesticides at this stage. The practice of oil emulsions abroad is mainly to prevent scale insects and claw lice, and to suffocate these insect pests through injection emulsions. In our orchard, if there are more scale insects or full claws in the past year, you can spray some oil emulsions, but you must master the amount to avoid damage to the fruit trees. In short, we must hold an objective view of chemical clean gardens. If the fungicide is selected, the best drug at this time is not to see how strong its bactericidal effect, but mainly to see how long its residual effect, Bordeaux fluid is currently known we have a long residual period of potency, can be used as a preparation Select medicine. For several manufacturers and their own preparation of lime sulfur, we have done a test, whether it is good for the control of rot bacteria and ringworm pathogens are not good. We used the lime sulfur mixture to prevent and control the full claw lice eggs. The effect was also general. Therefore, we do not recommend clearing the park with lime sulfur. When visiting fruit growers, some people think that the use of lime sulfur will cause damage to the bark. We have not received direct evidence on this argument. On the other hand, the "Rinograph Terminator No. 1" is a powder product jointly developed by our company and Mumeituli Company for the treatment of T. verrucosa, containing antagonistic microorganisms and carriers. After diluted with water and applied to the branches, a protective layer can be formed to protect the branches from infection by ringworm during the growing season. It is suitable for saplings or trees that have just been planted. It can prevent sunburn in summer. The best month to use this product is in March, mainly because there are no leaves at this time and it is easy for people to brush the branches. Brushing in April-May does not affect the effect, but it is only due to blade obstruction and brushing operation is difficult. This tree is not recommended for trees that have already experienced severe rotundity. Scented tea is also known as fruit grain of tea, is a kind of tea drink, in a variety of flowers and fruit drying, concentrate composition contains a variety of vitamins, fruit acid and minerals, but contains no caffeine and tannic acid, a variety of different flavors of scented tea is slightly different in composition, after brewing can still maintain the original flavor of fruit, rich aroma, add rock sugar drink, It can relieve mood and have the effect of beauty.

Flower and fruit tea, half is used to taste, half is used to appreciate, can not be put in a crock. When making tea, it is best to choose a transparent glass pot. It is also a kind of enjoyment to see the glittering and translucent tea water a little bit by the petals. In the brewing process of flower and fruit tea, the temperature should be slightly higher than that of general tea. Because the general tea has been rolled in the process of processing this process, and the flower and fruit tea in the production is generally dry after drying.
It should be noted that on the premise of brewing the flavor of tea soup, the brewing temperature should not be as high as possible, because some effective active substances in tea, such as polyphenols and flavonoids, will decompose at high temperature, so that the efficacy is damaged. Generally speaking, the higher the brewing temperature, the more bitter taste in the tea, can be appropriate to add a little orange juice, honey and other bitter. Of course, if you like a strong taste, you can also cook it.
Storage: The general storage method is to use a dry container, stored in a cool, dry environment. Drink as soon as possible after opening to ensure freshness. To serve, use a dry spoon. It is recommended to put scented tea into the refrigerator freezer, pay attention to storage should be away from fishy smell, avoid fish, seafood and other food put together.
