1、裂根成因:多发生于干湿不均、先旱后涝的栽培地块。应对:萝卜主根生长期间注意浇水要均匀,避免忽干忽湿。2、分叉成因:有多种原因,土壤理化性状差,土层浅,养分向侧根输送增多导致分叉;施用了未充分腐熟的有机肥,造成侧根生长;播种过密,间苗不及时,萝卜根部拥挤,主根弯曲,导致侧根旺长;因除草损伤了主根生长点而导致根部分叉。
1, split root causes: occurred in uneven wet and dry, drought drought after the first cultivation plots. Response: Radish root growth during the attention should be evenly watering, to avoid suddenly dry suddenly wet. 2, the bifurcation causes: There are a variety of reasons, poor physical and chemical properties of soil, shallow soil, nutrients to the lateral root increased delivery lead to bifurcation; application of undercomplete organic fertilizer, resulting in lateral root growth; sowing too close, not in time, Radish roots crowded, the main root bending, leading to lateral root Wang Long; weeding damage root growth and lead to root fork.
