在大田及室内条件下研究了尿素(Urea)、过磷酸钙(Superphosphate)、硫酸钾(Potassium sulphate)、硝酸磷钾复合肥(Phosphorus-potassium nitrate fertilizer)4种肥料、10个配比施用量对小麦禾谷胞囊线虫病的影响。室内盆栽结果表明,尿素375kg/ha处理对线虫的抑制作用最好,过磷酸钙900kg/ha、尿素300kg/ha和尿素225kg/ha次之;硫酸钾270kg/ha、硝酸磷钾复合肥525kg/ha、硝酸磷钾复合肥525kg/ha+硫酸钾120kg/ha3个处理对线虫的抑制作用均为负值。大田试验结果表明尿素300kg/ha、尿素225kg/ha和过磷酸钙900kg/ha3个处理对线虫的抑制作用最好;硫酸钾270kg/ha、硝酸磷钾复合肥525kg/ha、硝酸磷钾复合肥525kg/ha+硫酸钾120kg/ha3个处理对线虫的抑制作用较差。在抑制线虫增殖方面,复合肥525kg/ha+尿素75kg/ha处理效果最好,过磷酸钙900kg/ha、尿素300kg/ha2个处理对线虫增殖也具有一定的抑制作用;硫酸钾270kg/ha、硝酸磷钾复合肥525kg/ha、硝酸磷钾复合肥525kg/ha+硫酸钾120kg/ha3个处理则促进线虫增殖。产量测定结果表明,过磷酸钙900kg/ha、尿素300kg/ha、复合肥+磷肥187.5kg/ha3个处理增产效果均在10%以上;硫酸钾270kg/ha、硝酸磷钾复合肥525kg/ha、硝酸磷钾复合肥525kg/ha+硫酸钾120kg/ha3个处理增产效果均低于5%。
Urea, Potassium sulphite, Phosphorus-potassium nitrate fertilizer were studied under field and indoor conditions. The effects of 10 compounding doses Effect of wheat cereal cyst nematode disease. Indoor potted results showed that the best inhibitory effect of 375kg / ha on nematodes was 900kg / ha of superacid, 300kg / ha of urea and 225kg / ha of urea, 270kg / ha of potassium sulphate, 525kg / ha, NPK fertilizer 525kg / ha + potassium sulfate 120kg / ha3 treatment on the nematode inhibition were negative. The results of field experiments showed that the best inhibitory effect on nematodes was 300kg / ha urea, 225kg / ha urea and 900kg / ha superphosphate; the potassium sulfate 270kg / ha, phosphorus-potassium nitrate compound fertilizer 525kg / ha, 525kg / ha + potassium sulfate 120kg / ha3 treatment on the nematode inhibition is poor. In the aspect of inhibiting the proliferation of nematodes, the treatment effect of compound fertilizer 525kg / ha + urea 75kg / ha was the best, and the treatment of 900kg / ha of SSP and 300kg / ha of urea also inhibited the proliferation of nematodes; potassium sulfate 270kg / ha, Phosphorus and potassium compound fertilizer 525kg / ha, phosphorus and potassium nitrate fertilizer 525kg / ha + potassium sulfate 120kg / ha3 treatment is to promote nematode proliferation. The results showed that the yield increase was over 10% with 900kg / ha of SSP and 300kg / ha of urea, and 187.5kg / ha of compound fertilizer and phosphate fertilizer. The output of potassium sulfate was 270kg / ha, phosphorus and potassium nitrate fertilizer was 525kg / ha, Phosphorus and potassium nitrate fertilizer 525kg / ha + potassium sulfate 120kg / ha3 treatment yield effects are less than 5%.
