摘　　要：河套灌区番茄脐腐病发生较重,主要原因是番茄开花坐果后不再灌水,不能满足番茄正常生长的水分需求;施肥以化肥为主,重施氮肥,少施磷钾肥,不施钙肥,导致植株缺钙;河套灌区土壤盐渍化较高,生产中存在连茬、耕作管理粗放等。防治番茄脐腐病应从水分均衡供应、垄沟种植、增施有机肥、减施化肥和叶面补钙等方面着手。The main reason of navel rot of tomato serious occurrence in Hetao irrigation district were：no irrigation after flowering and fruit setting that could not meet the water demand for tomato normal growth;fertilization with chemical fertilizer-based,heavy application nitrogenous fertilizers,less application phosphate fertilizers and potassium fertilizers,and without application calcium fertilizers,that resulting in tomato calcium deficiency.Besides these,there were higher soil salinization,continuous cropping,and tillage management extensive.Control navel rot of tomato should proceed from balanced supply of water,furrow planting,application of organic fertilizer,reducing fertilizer and foliar calcium and other aspects.
