| 摘 要： | 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%。

| Abstract: | The effects of 4 fertilizers namely Urea,Superphosphate,Potassium sulphate(PS)and Phosphorus-potassium nitrate fertilizer(PPNF)at 10 dosages on cereal cyst nematode(CCN)of wheat were tested in the plots and pots.In pots,the control effect of Urea 375 kg/ha was the best and the effects of Urea 300 kg/ha,Urea 225 kg/ha and Superphosphate 900 kg/ha were lower than the former but higher than other treatments;The effects of PS 270 kg/ha,PPNF 525 kg/ha and PPNF 525 kg/ha+Potassium sulphate 120 kg/ha treatments were all negative.In plots,the control effects of Urea 300,225 kg/ha and Superphosphate 900 kg/ha treatments were better than other treatments.The effects of PS 270 kg/ha,PPNF 525 kg/ha and PPNF 525 kg/ha+PS 120 kg/ha treatments were poor.In suppressing the reproduction of CCN,PPNF 525 kg/ha+ Urea75 kg/ha was the best in all treatments and the Superphosphate 900 kg/ha and Urea 300 kg/ha treatments also suppress the reproduction of CCN,whereas PS 270 kg/ha,PPNF 525 kg/ha and PPNF 525 kg/ha+PS 120 kg/ha promoted the reproduction of CCN.The yield-increasing effects of Superphosphate 900 kg/ha,Urea 300 kg/ha and PPNF 525 kg/ha+ Superphosphate 187.5 kg/ha treatments were all above 10%,but that of PS 270 kg/ha,PPNF 525 kg/ha and PPNF 525 kg/ha+PS 120 kg/ha treatments were all below 5%. |
