The planting method of Nanfeng tangerine is as follows: 1. Selection of seedlings: adopt mother plants with excellent characteristics such as long-term drought without cracking fruit and rain soaking for bud grafting. Secondly, rootstocks should have obvious thick taproots and developed fibrous roots. The main stem of one-year-old grafted seedlings is 0.27-0.4 m high and 0.2-0.3 mm thick, with 2-3 branches, and each main branch has 2-3 branches and seedlings with other requirements and specifications. 2. Young tree management: The newly planted citrus reticulata can be fertilized frequently every 15-20 days from "fright" to "severe summer". After planting, 0.05 kg of acid fertilizer for raising seedlings, 0. 1 kg of compound fertilizer with 45% content and 0.05 kg of urea can be mixed before Qingming. Fertilization every year in the future can refer to the fertilization method of the first year, and cooperate with fertilization. 3. Adult fruiting tree: If it doesn't bear fruit in that year, as long as there are green branches and leaves, fertilization is generally not applied. However, if a large number of flowers begin to bloom in the next spring and no new branches are put out after the spring shoots, fertilization should be applied every 20-30 days from flowering to "big summer", and it can be suspended for one month until new branches can be put out. If there are no sporadic new buds after fertilization last month, it can be slightly increased. 4. Fertilization: After the orange tree enters the initial fruit stage, fertilization should be carried out according to the amount of flowers and fruits. If there are many trees with flowers and fruits, if the fertilizer is insufficient in spring, you can start to replenish fertilizer. 5. Irrigation in dry season: The first irrigation after a long drought must not be filled at one time, but only once every 4-5 days. After irrigation for 2-3 times, increase the amount of water with the number of pumping times to prevent sudden flooding from causing the death of underground roots and a large number of cracks on the aboveground parts. 6. Pest control: First, add enough and prepare each drug; Second, you need to start spraying when it doesn't rain on cloudy days or make up spraying after rain. Never wait for sunny days before spraying. In short, drugs with good control effect should be used as little as possible for all kinds of pests and diseases, so as to reduce production costs and prolong the service life of special drugs.
