The cherry tomato falls off the vine skillfully

The key points of early management are to control watering before falling the vine in order to reduce the water content in the stem and enhance its toughness. The falling vine should be carried out in the afternoon of sunny and warm weather, when the water content of the stem is low, the tissue is soft, it is easy to operate, and the injury of the stem is avoided and reduced. When falling off the vine, the old yellow leaves and diseased leaves in the lower part of the stem should be removed and taken to the outside of the shed to be buried or burned. All the fruits in this part should also be harvested to avoid the disease of leaves and fruits on the wet ground and form the disease center. Hang the vine when the first inflorescence opens. After the fruit of the first ear was harvested, the first ear of the second ear expanded rapidly and the third ear sat down for the first time. After that, the vine will fall once after each ear is harvested. Take the method of crossing and falling the vine before the plant, that is, remove the plant from the rope, knock off the lower old leaves, gently twist the plant to the same nearby plant and then re-hang the vine. The fallen vine should be in the same direction in an orderly manner and gradually coiled around both sides of the ridge. When winding the stem vine, it is necessary to bend the stem vine with the natural curvature of the stem vine, do not bend or bend in the opposite direction, to avoid twisting or breaking the stem vine. Each fall of the vine to maintain a leaf stem vine from the ridge surface of about 15 cm, each plant to maintain more than 20 functional leaves, should pay attention to the top of the front plant stem, can not exceed the back row, so as to avoid shading. Ensure that the leaf distribution is uniform, always in the best position of three-dimensional lighting and the best state of leaf area, and the leaf area coefficient is kept at 3mur4. The vine fell for 6 times during the whole growth period. Management after falling vine 1, temperature pruning and falling vine after a few days, it is necessary to appropriately increase the temperature in the shed to promote the wound healing of injured vines. The temperature should be kept at 20 ℃ 25 ℃ in the daytime and 15 ℃ at night. 2. In order to prevent the pathogen from invading from the stem vine and leaf wound, according to the common diseases of cherry tomato, Sukeling, Botrytis cinerea, chlorothalonil and mancozeb were sprayed after pruning and falling vine to control leaf mold, gray mold and early and late blight. When spraying, Shiyu 101 foliar fertilizer can be added to the pesticide, which can not only prevent disease, but also increase production. 3. Although falling vine under fertilizer and water management can reduce the fruiting position of the plant, it can not shorten the actual distance between the fruiting position and the root system. In addition, the growing nutrient body, such as insufficient supply of fertilizer and water, will cause problems such as worse and worse fruit quality and smaller and smaller fruit. therefore, sufficient fertilizer and water should be supplied to meet the needs of plant growth. Topdressing with potassium sulfate and other potash fertilizer, each time topdressing 15ml 20kg per mu, while watering. 4. Fork, pick old leaves and dry single branches, and remove other side branches in time. After picking the fruit of each ear, all the leaves below the ear are removed. The leaves above the ear can not be removed to ensure the good development of the upper fruit. Forking and picking old leaves should be carried out on a sunny day to make the wound healer. When forking, the forked hand only touches the razor, not the whole dry, to avoid the spread of tobacco mosaic virus. Picking leaves should be removed as far as possible near the branches, pay attention to do not leave petioles, so as not to produce gray mold.
