How to Fertilize Newly Planted Citrus Seedlings
The topic brought by the editor is related to how to fertilize newly planted citrus seedlings and detailed techniques for fertilizing and caring for citrus seedlings in flower cultivation. The specific content is as follows:
Citrus is a general term for oranges, mandarins, oranges, pomelos, trifoliate oranges, and kumquats. China has abundant citrus production, with a variety of high-quality varieties, and many people cultivate citrus. In the process of growing citrus, if you want the plants to have lush green leaves and sweet fruits, fertilization is essential. However, fertilization should not be done blindly and should be based on the plant's growth condition. When citrus is newly planted and at the seedling stage, the demand for fertilizer and the method of fertilization differ from other periods. Let's understand the fertilization methods for newly planted citrus.
I. Types of Fertilization
Fertilizing citrus seedlings during the seedling stage helps promote rapid growth of branches and develop sturdy stems and frameworks, which aids in the rapid expansion of the canopy and lays the foundation for abundant fruiting later on. Therefore, fertilization should focus on nitrogenous fertilizers to promote branch growth, supplemented by a small amount of monopotassium phosphate.
II. Timing of Fertilization
Fertilizing citrus seedlings should focus on promoting shoot growth. Fertilization can be carried out from May to June and July to August to promote summer and autumn shoots.
III. Frequency of Fertilization
Since newly planted citrus is still at the seedling stage, with a small and shallow root system and weak fertilizer absorption capacity, fertilization should be done in small amounts and frequently, applying thin fertilizers to avoid plant damage from excessive fertilizer concentration. The annual fertilization amount can be referenced as 0.18 to 0.3 kg of nitrogen fertilizer and 0.4 to 0.65 kg of urea per seedling, increasing annually with the growth of the seedlings.
IV. Method of Fertilization
Since the root system of citrus seedlings is shallow, fertilization should not be applied above the roots to avoid damaging the root structure and causing plant fertilizer injury. Fertilizer can be applied by digging trenches near the root zone. In winter and summer, leguminous green manure can be planted under citrus plants to improve soil fertility and reduce weed growth.
