Huangcheng orange is a kind of citrus. How to cultivate?

1, Transplanting technology First of all, we must choose excellent citrus orchards. Emperor Citrus has relatively large regulations on soil quality, loose soil layer and various organic compounds, which is more suitable for planting. However, it is necessary to choose areas with flat terrain and strong photosynthesis, which is beneficial to irrigation and convenient management. The relative density of emperor citrus planting must be effective, not too lush and loose.

2. Weeds and harmful residual leaves must be removed as soon as possible when planting the Royal Citrus Orchard. These residual leaves and weeds will digest and absorb the nutrients in the soil layer of the plantation, and the insufficient nutrition of Imperial orange seedlings will lead to insufficient nutrition of citrus, which will further limit the yield next year. Therefore, before planting the seedlings of Citrus grandis, the plantation must be cleaned, cleaned and watered to ensure a good atmosphere for planting the seedlings. Ploughing land resources is also good for citrus, which can increase organic compounds in the soil and kill redundant pests.

3. Effective fertilization is indispensable for the growth and development of pomelo seedlings. The three elements of fertilization are base fertilizer, flushing fertilizer and topdressing. In the process of transplanting base fertilizer, a certain amount of organic fertilizer should be applied to the soil layer, and it should be reasonably combined with water to complete fertilizer flushing under the condition of watering the seedlings of Citrus grandis.

Topdressing is the situation when fruit is picked. Because the fruit of Emperor Citrus is in the period of Peng Da, it needs a lot of nutrition. The nutrients in the soil layer are not suitable for the development of citrus, so it is necessary to topdress citrus. Topdressing can make the fruit of "Emperor Citrus" pass through the Peng Da period smoothly, and increase the total output in the following year.

4. Trimming and trimming technology The trimming and trimming of Imperial Citrus is to make the gas in the citrus orchard flow, which can play the role of natural ventilation and heat insulation. This shows the necessity of cutting and pruning imperial oranges. Pruning can also deal with the excess nutrient outflow from the stem of Imperial Citrus, and transport nutrient elements for the excellent fruit trees of Imperial Citrus. In the case of pruning seedlings, we can take the second best according to the development of Huangdi citrus trees, and cut off some diseased leaves and long branches.

5. Ring cutting and flower protection For some over-developed trees and native trees, at the same time of "moderate water treatment" after the autumn shoots mature, ring cutting is carried out from "snowfall" to "winter solstice solar terms", ring cutting is carried out at the main stem or branch of the tree, phloem is cut off without hurting it, or paclobutrazol is sprayed to deepen roots and smelt. To promote flower promotion. Generally, weak trees and big trees are not suitable for girdling, so foliar fertilizer should be sprayed, liquid fertilizer control should be strengthened, and leaves should be left in winter to adjust the flower amount in the next year.
