Wogan's favorite plot should be a place with loose soil, abundant fertility, convenient irrigation and drainage, and small leeward-to-sunny slope ratio. Before planting Wogan, you can dig deep with a high-powered tractor and dig deep in the whole garden. When plowing, you should choose to do it when the soil moisture is not very high. The direction can be determined by a straight line at the same height or by a vertical road. The depth of the plow is 60 cm to 70 cm, then rake it once or twice until the ground is flat, and then dig the drainage ditch according to your own terrain. The ditch is 60 cm deep and then raked flat. You can also dig a pit with a length of one meter, a width of one meter and a depth of 0.6 meter, put 50 kg of decomposed organic fertilizer and 1 kg of calcium phosphate into into the pit, mix them with soil, and then put them back into the pit. The height of the pit is higher than the ground.
2. Planting of Wogan seedlings.
Before planting Wogan, you should choose seedlings with good plant type and complete root system, and pay special attention not to carry some seedlings with diseases such as Huanglongbing, Canker and Decline. When planting Wogan, the spacing between each seedling can be 2 meters to 3 meters, and the spacing between each row can be 3 meters to 4 meters. You can plant about 56 plants to 1 10 per mu of land, or you can choose flexibly according to your own environment and needs. Vogan is usually planted in the south from February to May every year, during which the temperature begins to rise and the rainfall is more. When planting, you can choose to start on rainy days, or you can start planting on rainy days in September-11month. Greenhouse planting or greenhouse planting can be planted all year round. Before planting Wogan, soak the whole sapling in 0. 1% potassium permanganate solution for about two minutes, then take it out and dry it for about three minutes, and then rinse it with clear water. The purpose of this is to kill the bacteria on the sketch surface, and then soak the roots of citrus seedlings in the mixed solution of sterilization, insecticidal and nutrient solution for about 8 hours. The seedlings taken out can be planted after being stained with the yellow mud from the solution.
3. Fertilizer and water management
Generally, it can be concluded that nitrogen fertilizer should be used in spring, potassium fertilizer in summer and compound fertilizer in autumn. When the fruit expands, it should be watered thoroughly with bran water, and then topdressing after receiving the goods to supplement nutrients and help the tree to resume growth. Every year, 50 kilograms of fermented organic fertilizer should be used for each Wogan tree, and then peanut bran and calcium superphosphate should be used for topdressing. From September to 65438+February, the fruit of Wogan will swell. If the climate is dry, we should irrigate Vogan. It should be implemented on the principle of applying less chemical fertilizer each time and applying more times. The fruit will ripen from June to March in 65438, and the water should be controlled to make the fruit sweeter.
4, plastic pruning
In spring, some spring shoots should be kept in time, summer shoots should be cut off, autumn shoots should be placed in a unified way, and long winter shoots should be strictly controlled. That is to say, when the spring night grows to about 5 cm, two or three buds grow well in different directions on each branch. The purpose of doing this is to remove too dense places, cut short branches and remove some dry and diseased branches. When the branches grow too vigorously and leave 6 to 7 leaves, the core should be removed to avoid excessive growth. All summer buds should be cut off, autumn buds should be put together in August-September, and all scattered buds should be smoothed. If some fruit trees look weak, you can leave some autumn shoots and cut off the rest and winter shoots according to the growth situation. In winter, the purpose of pruning is ventilation and light transmission, as well as the distribution of branches. Try to make the crown as compact as possible, cut off all the diseased branches, and then gather them together to burn or bury them. Wogan can be harvested in about 65438+ 10, and the maturity will be high by mid-February. So it can be served in two important festivals, the Spring Festival and the Lantern Festival. It is best to harvest before March, if it is too late, it will affect the flowering quality of the next season. Usually clean Vogan can be stored at room temperature for more than one month. If it is not clean, the fruit surface will be destroyed by green mold and Penicillium. This will affect the appearance of the fruit and the sales progress.
