First, summer pruning of apple trees is different from winter, but the purpose is the same, all for the high yield, stable production and longevity of apple trees. The difference is the phenological period is different, one is dormancy trim, one is growing season trim. Therefore, some specific technologies are different. The specific techniques of summer pruning are as follows: 1. Thinning: Many branches of new shoots are sprouted on branches from one to two years through techniques such as sprouting and branching. These new shoots differ according to their location, and the length and growth of the new shoots are different. New shoots sprouting at the upper back may be more prosperous and are generally difficult to retain. In particular, too many buds, too strong backs, and peripheral branches use this technique. 2. Short cuts: For a few sites where there are not many sprouts, where the space is relatively large, short-cut culture sticks can be used. Specific operations: Select the new shoots of the year, leave about 5 large leaves for short cuts, and promote secondary sprouting. . The weaker secondary tree has weakened secondary buds and may have flower buds. Magnolia still has to be twice shorter, but the second sprout can only slow down the trend and the probability of flowering is very small. 3. Twisting tip: The site of the new shoot is not suitable, and it can be used to change the direction of the growth of the stick branch by twisting the tip to achieve a reasonable use of space. Specific approach: When the new shoots are semi-woody, the new shoots will be twisted and rotated at a 5 to 6 cm base at a new angle to a certain point so as to be fixed in a larger space. 4. Branch opening angle: refers to the larger perennial branches cultured in the stem or main branch, because the angle is too small, the direction is not right, and artificial measures to change the angle and direction of growth. Spring, summer, autumn and winter can be applied in all seasons, but the toughness of the branches in the growing season is relatively strong, and the branch opening angle is better. 5. Circumcision: The principle of circumcision and circumcision is the same, except that the degree of wounding is different. The circumcision is more easily healed and the wound recovers faster. The girdling damages the tree body and severely damages the nutrient distribution in the upper and lower parts of the tree, resulting in massive root deaths and weakening the tree vigor. Whether it is circumcision or circumcision, remember not to perform it on the trunk and permanent branches, but on some temporary branches and auxiliary branches. Second, the prevention and treatment of leaf diseases in recent years caused a large area of ​​deciduous fruit trees is not insect pests, but disease. Diseases that damage fruit trees include: brown spot, round spot, grey spot and leaf spot. Among them, brown spot and leaf spot disease are the main diseases. Over the years, people have established a set of regular methods for the prevention and treatment of leaf diseases, which have played a positive and effective role. However, with the change of climate, the increase of orchard area, the increase in the number of bags, and the period of bagging are getting longer and longer. The reason is that the interval between the last drug before bagging and the first pass after bagging is too long. The validity period of the previous drug is generally no more than 10 days, and if it is more than 10 days when bagging, neither the protective agent nor the therapeutic agent will work. The germs have invaded the foliage, and it is a mistake to spray the Bordeaux mixture on the trees in the traditional way. To update ideas and change strategies. 10 days after the bagging period, the bactericidal and more effective tebuconazole were used to kill the bacteria in the garden, and the protective Bordeaux mixture was sprayed again during the effective period. Change the previous "protection, treatment, protection, and treatment" to "treatment, protection, treatment, and protection." Do not use carbendazim, thiophanate-methyl or thiophanate-methyl if late leaf spotting occurs. Should use imported "proton and homemade iprodione." Since carbendazim is almost ineffective against leaf spot, thiophanate-methyl and thiophanate-methyl must be converted into carbendazim in plants to function as a bactericidal agent. Third, the cooling watering this formulation is due to Apple's environmental conditions have changed after bagging. On sunny days, the temperature outside the bag is generally around 30°C. The bag temperature is as high as 56 °C ~ 58 °C, easy to cause sunburn damage. Therefore, watering the bagged consequential garden can effectively change the microclimate of the orchard, and it can reduce the temperature and prevent sunburn. Of course, when the orchards are dry and water shortage, the role of watering is far more than these. Fourth, flood prevention and drainage This is relative to the previous topic. The northern, northern, northern and central regions of China are the main flood seasons. In recent years, sudden death of fruit trees due to high rainfall has often occurred. Rain started on August 8th, 2010, and it stopped until September 10. It dropped 23 days in one month. As a result, the fall of fruit trees in autumn is widespread. In the spring of 2011, many fruit trees were rotted and dead. This was all the trouble caused by the rain.
Fruit and vegetable powder also means fruit and vegetable juice powder. The making method is about first crush the fruit and vegetable to juice, then vacuum concentrate it, and then use high temperature to spray it to powder. Do not add any flavors and artificial colors. To a great extend retain the nutrition, color and flavor of plants and fruits.
Products are widely used in food, beverage, cosmetics, medicine, health food and other fields.
