Peach bagging technology
First, bagging and picking bag 1, the choice of paper bag type Peach bagging paper bag selection should be based on the tree growth situation, production goals, economical ability and reasonable choice. Tests have proved that special bags for peaches such as Jiatian bags and Kaixiang bags are effective. 2. During the bagging period, the fruit should be bagged within 30 days after flowering; the bagging time should be from 9:00 to 11:00 and 2:00 to 6:00 in sunny days. 3, bagging operation technology before bagging the whole bag of fruit bags placed in a damp place, so that return damp, flexible; selected young fruit, carefully remove the petal and other debris attached to the young fruit, left hand hold the paper bag , The right hand open the bag mouth, or open the mouth with a mouth, so that the bag body bulge, so that the bottom of the bag at the bottom of the two vent holes to open the mouth, hand bag mouth 2-3 cm, bag mouth up or down Put the fruit in, insert the fruit, put the fruit handle on the open base of the bag (do not put the leaves and branches into the bag), and then fold the bag mouth at the incision from the two sides of the bag mouth in order of "folding fan". The tying wire binds the bag opening to the fold, tears it from the connection point above the line opening, turns the tying wire 90, and tightens the bag mouth by rotating it along the bag mouth for 1 week so that the young fruit is in the center of the bag body and is vacant in the bag. To prevent the bag body from rubbing the fruit surface, do not wrap the tie wire around the handle. When the bag is being bagged, the direction of force must always be upward so as not to pull off the young fruit. The force should be light, try not to touch the young fruit, and the bag mouth should be tightly tightened so as to prevent the insect from crawling into the bag to harm the fruit and prevent the paper bag from being blown off by the wind. In addition, the bare fruit on the upper part of the crown and on the back of the backbone should be used in order to avoid the occurrence of sunburn. The bagging sequence is first up, then down, first in and then out. The average number of bags per 667m2 is about 6500. 4. The period of picking the bag and the method of picking the bag vary greatly depending on the type of bag and variety. The time of picking the bag of peaches is not applicable. 7-7 days before the entire bag. The best time to remove bags during the day is from 9 to 11 o'clock in the morning and from about 3 to 5 o'clock in the afternoon. In addition to the paper bags on the south side of the morning, we must avoid the strongest time of daylight at noon so as to avoid sunburn. Picking time is too early or too late to reach the expected effect of bagging, premature picking, dark fruit surface, poor smoothness; too late to remove the bag, the fruit surface color is light, storage fading. When the double bag is removed, the outer bag is torn along the bag tangent line, and the inner bag is removed after 5-7 days. In addition to the single bag, the bottom of the bag is opened for ventilation or the paper bag is torn to a long strip and removed after a few days. Second, the consequences of bagging Park Management 1, Fei Shui Management Bagging Taoyuan strengthen fertilizer and water management and blade protection, in order to maintain a robust tree vigor, to meet the fruit growth needs. Due to the decrease in calcium content in bagged fruits and the vulnerability to bitter pit disease, a 300-500-fold calcium amino acid or amino acid compound fertilizer was sprayed once a month in July-September. In the late June, 40 days and 20 days before harvesting, 50010-6 rare earths were sprayed once, or photosynthetic micronutrients, Nongjiawang and other micronutrients were sprayed in June, July and one month before harvest to increase Bagging fruit soluble solids content. During the period of fruit enlargement and before bag extraction, water should be poured one time to meet the water requirement of bagging fruit and prevent sunburn. 2. Pest control In addition to normal pest control throughout the year in the orchard, the fungicide and insecticide should be sprayed on the whole garden 1-2 days before bagging to effectively control rot disease, cotton bollworm and fleas. The harm. Pharmaceutics include spray 600 times, 70% thiophanate-methyl 800 times, Polaroid 1500 times, cotton God No. 1, hyperosmotic extermination net. Do not use organic phosphorus and Bordeaux mixture to prevent fruit rust. During the fruit bag growth period, a fungicide with leaf protection and fruit protection should be sprayed as usual to prevent bacteria from entering the bag with rain. After the bag is sprayed with 1 spray (600 times), thiophanate (25%, 800 times), etc., to absorb fungicides and control the rotten fruit disease caused by the latent bacteria in the fruit, and spray it 1-2 times at the same time. The effect of color-enhancing drugs, such as 300 times the potassium dihydrogen phosphate, 800 times the Shikang Lu, Nongjia Wang, etc., in order to enhance disease prevention. After harvesting, the used paper bags will be burned in a timely manner to eliminate the source of the diseases and insects that lie on the bags, so as to reduce the harm of the following year. 3, bagging fruit harvesting In order to improve the fruit quality of bagging fruit, and more high-quality production of high-quality fruit, according to the fruit coloring situation appropriate, batch harvest. In the appropriate harvest period, the later the harvest, the better the coloring, the better the quality. Because the bagged fruit skin is thinner and tenderer, touch, pressure, thorns and scratches are minimized during harvesting and handling.
