Root vegetables include a wide variety of radish, root mustard (turnip), turnip cabbage, turnip, horseradish and carrots. The whole growth process of root vegetables includes two stages of leaf formation and meat root swelling. In the early growth stage, more nitrogen is needed to promote leaf growth. Later, more potassium is needed to promote the transfer of photosynthetic products from the leaves to the storage organs.
The ratio of radish to nitrogen, phosphorus and potassium is 1:0.2:1.8. Radish roots are well developed and need to be applied to basal. Taking winter radish as an example, the general base fertilizer Mushi organic fertilizer 2500-3000 kg, 60-80 kg of biological organic fertilizer, calcium superphosphate 10-15 kg, ploughing into the soil, doping leveling. In the early stage of growth, radish requires more nitrogen fertilizer, which is conducive to promoting vegetative growth. In the middle and later stages, phosphorus and potassium fertilizer should be added to promote the rapid expansion of the fleshy root. Generally medium-sized radish topdressing 3 times or more, mainly in the early stage of vigorous growth on the ground, the first and second topdressing combined with uniform seedlings, when the "break belly" when the third top dressing, Mushi biological organic fertilizer 10 kg, with superphosphate Each 5 kg of calcium and potassium sulfate. When the large radish reaches the "bare shoulder," the mu will be topped with 5-10 kg of potassium sulfate.
Carrots should be selected for deep fertile soil, convenient irrigation and drainage, loose sandy loam soil or loam, and the ratio of nitrogen, phosphorus, and potassium needs to be 1:0.4:2.6. Basal fertilizer is usually 3,000 kg of Mushi organic fertilizer, 80-100 kg of bio-organic fertilizer, 25 kg of superphosphate, 5 kg of potassium sulfate, and 25-30 cm of deep plowing. Top dressing depends on the fertility of the soil and the growth of the field plants. It can be topdressed 1-2 times. The weak growing plots in the leafy growing season can be combined with watering 10 mu of bio-organic fertilizer after harvesting, 20 kg of bio-organic fertilizer topped with mu under root mass expansion and 10 kg of potassium sulfate.
