1 裂根造成萝卜裂根的原因,主要由于选择土壤不适和整地不细,其次是植株生长过程中土壤水分不均匀。如在萝卜生长前期,高温干旱而又供水不足,其肉质根的周皮组织便易老化,如到生长中后期温度适宜,水分充足时,则木质部薄壁细胞再度膨大,而周皮层细胞已不能相应的生长,这就不可避免地要出现裂根现象。或者在肉质根肥大过程中,水分供应不均匀,或雨水失调,先干后湿也会引起肉质根内部细胞膨大的速度超过外层细胞而产生破裂的现象,所以萝卜采种田不要选择粘土地,在萝卜生长前期如遇到干旱要及时送水、到母根迅
1 split root causes radish split root causes, mainly due to the choice of soil discomfort and site preparation is not fine, followed by the growth of plants in the process of uneven soil moisture. As in the early stage of radish growth, high temperature and drought and inadequate water supply, the fleshy roots of the peritoneal tissue is easy to aging, such as the late growth of moderate temperature, adequate water, the xylem parenchyma cells once again dilate, and the peripheral cortex cells can not The corresponding growth, which is inevitable to crack the root phenomenon. Or in the fleshy root hypertrophy process, the uneven supply of water, or rain disorders, the first dry wet will cause fleshy root cells within the expansion rate of more than the occurrence of outer cells and the phenomenon of rupture, so radish farming not to choose clay, Early in the growth of radish in case of drought to timely delivery of water to the mother root Xun
