Bagging period kiwifruit bagging should be carried out about 30 days after flowering. Early-maturing varieties of Hongyang will begin from June 7 to around 20; Late-maturing varieties Hayward, Jinxiang, Xu Xiang, etc. from June 20 From July to July 10, use 10-15 days to finish. The bagging is too early to easily injure the fruit peel and is not conducive to the development of young fruit; when the bagging is too late, the fruit surface is rough and the bagging effect is affected, and the lignification of the fruit handle is not easy to operate. Bagging should be done in the morning after the dew is dry, or after the liquid medicine is dry. The sunny days are generally 9:00-11:30 in the morning and 4:00-6:30 in the afternoon, and should not be bagged immediately after the rain. 3. Bagging method The bag should be placed in a wet place the night before, so that the bag can be softened to facilitate the tight bag opening. The specific operation steps are as follows: 1 Hold the paper bag with your left hand, and open the bag mouth with your right hand so that the bag body will bulge and make the vent hole for the two corners of the bag open; 2 bag mouth upwards, and 2-3cm below the bag mouth under both hands, Put the young fruit into the bag so that the handle sticks to the base of the bag opening; 3 fold the left and right sides of the bag laterally to the middle and fold the bag mouth into a “V†shape Mouth, complete bagging. Set the time to pay attention to the strength should be appropriate, the direction must always be upward, to avoid the zhasuo wrapped around the handle, to tie the bag mouth. The purpose of this operation is to put the young fruit in the center of the bag body and hang it in the bag to prevent the bag body from rubbing the fruit surface and prevent the rainwater from leaking, the invasion of pathogens and the falling of the fruit bag by the wind. Second, after bagging orchard management 1, often check the bag. Regularly check the growth of bagged fruit, investigate the fruit growth and pests and diseases, and take corresponding measures in time to find that the broken bag is replaced in time. 2, timely irrigation. The weather is prolonged and the temperature inside the fruit bag is too high, and it is prone to fruit sunburn. It should be balanced and timely watered. Pay attention to drainage during the rainy season to prevent rooting. 3, suitable fertilization. In the middle and early June, top-dressing “Strong Fruit Fertilizer†was applied with 1-1.5kg of N, P and K compound fertilizers. In the middle and late July, the fruit coloring stage was followed by appropriate application of P and K fertilizers, and the Shi Tianbang Vegan Kiwi Organic Compound Fertilizer was 1.5kg, or Potassium sulfate compound fertilizer 1kg. In combination with spraying, leaves such as CA2000 Ca-Ba, Qirui amino acid chelating fertilizer, potassium dihydrogen phosphate, and biogas slurry were sprayed every 15 to 20 days. 4, timely implementation of pest control. After bagging, it is mainly to protect the leaves and reduce the number of spraying. From July to September, the main prevention and control pests such as red spider, scale insect, and brown spot disease were selected. The fungicides and insecticides used were selected from the group consisting of the extermination of bacteria, agricultural resistance 120, spray g, broom net, and green kungfu. From the middle of September, it began to control ulcer disease. The medicine used was 10% quick 500 times fluid, Bo doctor 1200 times, etc. The fruit was sprayed 15 days before fruit picking, and once after fruit picking and winter shearing ended. 5, remove the fruit bag 7 days before harvest, improve fruit surface coloration. In the event of rainy weather, it is possible to postpone bag removal and postpone harvesting so as to avoid contamination of the fruit surface caused by rain.
