The application of the base fertilizer should be deep-plowed before planting and the base fertilizer should be applied. There are two methods of application: application and ditch application. Where solid fertilizer is applied, it should be mixed with fine soil and mixed. The base fertilizer has a great influence on the shape of fleshy roots. When the amount of chemical fertilizer is large and the organic fertilizer is small, the proportion of deformed roots is obviously increased. Increasing the application of decomposed organic fertilizer as base fertilizer can reduce the formation of deformed fleshy roots.
The application of micro-fertilizer carrots absorbs more calcium, but excessive calcium content will reduce the content of carrot sugar and carotene. If the calcium content is too small, it may cause hollow disease. Carrots do not absorb much magnesium. The more magnesium, the more sugar and carotene, the better the quality. The calcium, magnesium and phosphorus fertilizers can be sprayed once at the seedling stage and the leaf growth stage, and the new high-fat film powder is sprayed to increase the utilization rate of the active ingredients of the fertilizer.
Reasonable topdressing of carrots in addition to the application of base fertilizer, but also topdressing. In the later stage of growth, excessive water and fertilizer should be avoided, otherwise it will easily cause cracking and is not conducive to storage. Topdressing can be carried in with water, and it can also be applied to human excrement and water. At the same time, spraying the fruit and strengthening the body, the nutrient transport conduit of the underground fruit is thickened, the fruit fruit is expanded and the fruit is strong, and the fruit is strong, high quality and high yield.
