Areas affected by typhoons should strengthen the control of fertilizer, water, and pests and diseases to promote the restoration of tree vigor. In August, all lychee varieties were used to attack autumn shoots. Cultivation and management were mainly to restore tree vigor and cultivate strong autumn shoots. The main task of the longan is timely harvesting, fertilization to restore vigor, and attacking autumn shoots. Areas affected by flooding or typhoons must do a good job in restoring production. Premature litchi: Fertilizing and attacking the last autumn shoot Precocious varieties such as March Red and White Sugar Poppy will attack the last autumn shoot in late August or early September. According to the growth conditions of various orchard plants, different cultivation management techniques are adopted. 1 Prepare to extract the orchard of the last autumn in late August. Apply a proper amount of compound fertilizer in mid-August. If the tree is weaker, add more nitrogen fertilizer. Prepare the fall orchard in early September to spray 1-2 times of agricultural nucleotides to increase the photosynthetic efficiency of leaves and promote the ripening of branches; apply appropriate amount of compound fertilizer in late August and timely extract new shoots. 2 In the orchard that was withdrawn early in the last autumn shoot, in order to prevent the withdrawal of winter shoots, the application of nitrogen fertilizer may be increased, the length of shoots may be appropriately lengthened, and the ripening of the shoots may be postponed. After the last autumn shoots were taken out in mid-September, the leaves couldn't turn green in early October. When the new shoots were just taken out, they were sprayed once to control the shoots, and the fertilization ditch was used to cut the roots to control the shoots. Medium ripe litchi: Develop every autumn shoot The medium-maturing varieties such as Shuidong, Heiye and Yuzixiao are in the autumn shoot growth stage, and the main work is to attack the fall shoots. According to the growth status of each orchard, each autumn shoot is cultivated. 1 fertilization. The growing orchard is spraying 1-2 times of agricultural nucleotides to improve the quality of the leaves. The new shoots are in an old orchard. For the next shoot, a compound fertilizer plus appropriate amount of nitrogen fertilizer can be applied. In the orchard that germinates, if there is a shortage of fertilizer, it is necessary to use more rainwater in recent days. The soil is moister and appropriate nitrogen fertilizer is applied. 2 thin branches. After the pruned tree, the first time the new shoot is mature or begins to mature, it can remove the dense branches and leave strong branches. 3 spray tips. After trimming, several new shoots can be taken out. After each new shoot, only one shoot can be extracted. If the new shoot branches again, it will affect the roughness of the resulting mother shoots. Late mature litchi: Spray protection for new shoots Late varieties such as glutinous rice bran, cinnamon and Huaizhi are in the autumn shoot growth period. This year, more rain and well-managed orchards can be used to extract new shoots in time, but the quality of new shoots will vary depending on the level of management. 1 fertilization. Newly grown shoots need to be treated with compound or organic fertilizers and nitrogen fertilizers. The orchards that need to continue to fade should be fertilized when the shoots turn green to prepare for the next shoot. 2 Trim. Late fruiting twigs result in finer shoots, so they must not be overly thinned, and insufficient number of shoots will affect yield. Only the vaginal branches, drooping branches, and branches damaged by the pests can be removed. 3 spray protection of new shoots. Longan: Timely fruit picking spray tip Longan fruits must be harvested in time for fruit ripening and increase economic income. More rain this year and another typhoon have a great impact on the production and quality of longan. Early maturing varieties and early maturing areas began to collect fruits in late July. Small areas of orchards should be harvested and new shoots should be started. Large orchard or late-maturing varieties, late mature production areas, the orchard has just entered the big harvest, affected by the bad weather, fruit cracking is more serious. 1 fertilization. Whether or not it has been harvested, fertilization should be timely and new shoots should be released early. In particular, there is more rain in recent days. If there is enough fertilizer, new shoots will be easier to pull out. 2 timely fruit picking. According to the weather forecast, there will be more than one typhoon in the near future. The wind will hit the fruit and the rain will cause cracking, so only selling the fruit as soon as possible can earn income. 3 After harvesting, the orchards to be harvested should be properly pruned and have an effect on the quality of shoots. 4 spray tips. Disaster consequences Park production technology I. Wind damage resumption technology Spray and prevent disease. For trees that are blown or tilted by strong winds, the soil at the base of the root should be dug first and slowly lifted up. Supports should be set up to support the tree body. After the broken roots are trimmed, appropriate amounts of decomposed organic fertilizer and phosphate fertilizer are used to mix topsoil with soil. To speed up the recovery of growth. If you are eager to get up, it is easy to injure the roots so that a lot of fallen leaves or the whole plant die. For injury has caused dead, irreversible branches, can be flattened or cut from the vicinity of the injury site, and then choose to stay in the vicinity of new branches or leggy branches to cultivate, to supplement the loss of some of the canopy vacancies. For trees with less injury, rescue them in time. Lift or lift the split branches to restore their condition and move the weight of the branches to the support or sling. The inclusions should be removed from the cracks in the base of litchi and tightly tied with rope or iron wire so that the cracks are tight and seamless. The outside is tightly wrapped with film to facilitate healing. It is necessary to strengthen the control of fertilizer and water and pests and diseases to promote tree restoration. Second, post-damage rehabilitation technology Releasing accumulated water and correcting fallen fruit trees as soon as possible and setting up pillars to prevent swinging. Remove sand and silt from the tree tray and apply soil to the exposed roots. Carry out the deep turning of the tree plate or the whole garden to spread the soil water, strengthen ventilation and promote the growth of new shoots. Strengthen tree protection and spray pesticides in time. Increase the amount of pruning to keep the balance up and down. As a result, many trees need fruit thinning to reduce the physiological burden on the roots, which is beneficial to the restoration of the plants.
