The roots of the roots occur mostly in cultivated lands with uneven dry and wet conditions and drought and drought. Countermeasures: During the growth of radish roots, pay attention to watering evenly to prevent it from drying out. Bifurcation radish lateral root dilatation bifurcation, there are many reasons: (1) poor soil physical and chemical properties, soil shallow, many gravel, hindered the normal growth of the main root, nutrient transfer to the lateral root lead to bifurcation; (2) applied Incomplete organic fertilizer, resulting in lateral root growth; (3) too dense planting, seedlings are not timely, radish roots crowded, the main root bent, leading to prolonged lateral root; (4) due to weeding damage to the main root growth point and cause root fork. Preventive measures: Select the deep, loose fertile loam soil cultivation radish, pay attention to intensive cultivation; basal fertilizer applied high-quality decomposition of soil miscellaneous fertilizer; after seedling emergence and time seedlings, Dingmiao. When the radish is planted in autumn, it is prone to crookedness in the conditions of high temperature and drought, pre-wet and dry conditions, or plots that are planted too early and are harvested too late. Preventive measures: cultivation should choose the soil deep, loose and fertile soil land, and in the radish "break belly" balanced fertilizer after watering, to avoid uneven wet and dry, the main root fully grow and timely harvest. Black heart, black radish black heart, black skin has two main reasons: (1) black rot. The external symptoms of radish fleshy roots were not obvious. After cutting, the internal tissues were dry rot. The pith was mostly black and hollow. (2) Soil compaction, the application of organic fertilizer is not fully decomposed, resulting in lack of oxygen in the radish roots, resulting in black heart, black skin. Preventive measures: (1) appropriate sowing, not continuous cropping, to avoid planting in low-lying land, spray 72% of agricultural streptomycin 3000 times in the early stage of black rot, once in 7 to 10 days, and spray 3 to 4 times; (2) intensive cultivation, avoiding soil compaction, application of high-quality organic fertilizer as a base fertilizer. Spicy radish grows with heat, drought, and lack of fertilizer. The main root grows slowly, is small in size, and has a high content of mustard oil and a strong spicy taste. Preventive measures: Rational fertilization to avoid prolonged drought in the soil. Improper fertilization of bitterness, partial application of nitrogen and phosphorus and potassium fertilizers, radish in the main root of nitrogen containing more alkaline compounds, resulting in high content of bitter gourd and bitter. Preventive measures: With N, P, and K fertilisers, no nitrogen fertilizer is applied.
