摘　　要：为减轻黑龙江省半干旱区水稻稻瘟病及纹枯病的危害程度,应用农药配施硅肥技术开展综合防控试验。结果显示,在30 kg/hm^(2)纯Si作底肥,分蘖末期喷洒2%春雷霉素水剂1800 mL/hm^(2)和孕穗末期喷洒27%戊唑·噻霉酮水乳剂450mL/hm^(2)的条件下,对稻瘟病和纹枯病的防控效果最好,防效分别为100%和96.59%;水稻产量最高,为9145.50 kg/hm^(2),较对照增加5.03%,病害损失率降低5.03%。In order to relieve the hazard level of rice blast and sheath blight in semi-arid area of Heilongjiang Province,using the technology of silicon fertilizer in combination with pesticides to carry out the diseases control test.The main results indicated as following.Under the conditions of silicon fertilizer 30 kg/ha,2%kasugamycin 1800mL/ha and 27%tebuconazole·benziothiazolinone 450 mL/ha,the diseases control results were obvious and the control effects to rice blast and sheath blight were 100%and 96.59%,respectively.Furthermore,the yield of rice was 9145.50 kg/ha,the production increased 5.03%and the disease loss rate reduced 5.03%than the control.
