钙、硼肥及植物生长调节剂对芹菜黑心病的田间防效

芹菜黑心病是一种生理性病害,防治难度较大。本试验选用4种钙肥、1种硼肥、6种植物生长调节剂对芹菜黑心病进行田间防效试验。结果表明:叶面喷施4种钙肥对芹菜黑心病均有一定的防治效果,其中0.5%氯化钙的防效最好,两年防效均在90%以上;硼肥对芹菜黑心病的防治效果较低,仅为23.08%;6种植物生长调节剂中,6%阿泰灵对芹菜黑心病的防治效果最好,防效可达90.62%。

Effect of Calcium Boron Fertilizer and Plant Growth Regulator on Controlling Celery Black Heart

Celery black heart disease is a kind of physiological disease．Its prevention and treatment is more difficult．This study selected 4 kinds of calcium fertilizer，one boron fertilizer and 6 kinds of plant growth regulators to conduct field experiment on controlling celery black heart disease．The results showed that foliage spray 4 kinds of calcium fertilizer had certain control effect on celery black heart disease．Among them，0.5% calcium chloride had the best control effect．The control effect was over 90% in 2 years．The effect of boron fertilizer on controlling celery black heart disease was very limited，only 23.08%．Among 6 kinds of plant growth regulators，the control effects of 6% Artailing was better（90.62%）．
