Abstract
Recently,the number of underground pests increases rapidly,which seriously affects the yields of underground-fruit crops. This experiment studied the effects of application of compound fertilizer with different pesticides added on the yields and infestation rates of sweet potato and peanut. Results indicated that the treatment of mixing 45 kg/ha of Nongboshi particle pesticide and fertilizer(600 kg/ha) increased yield of sweet potato by 5. 71% and decreased infestation rate by 27. 06 percentage points. For peanut,mixing 45 kg/ha of Nongboshi particle pesticide and fertilizer increased its yield by 6. 02% and decreased infestation rate by 1. 02 percentage points. Application of pesticide-added compound fertilizer could reduce the harm of pests to underground-fruit crops, but had little effect on efficiency of the fertilizer. For sweet potato, the insecticidal effect of 22. 5 kg/ha of Nongboshi particle pesticide with fertilizer applied immediately after mixing (infestation rate 50. 84%)was nearly the same as the treatment of 45 kg/ha of Nongboshi particle pesticide with fertilizer applied 3 weeks after mixing (infestation rate 50. 46%) ,but was better than the treatment of applying 22. 5 kg/ha of Nongboshi particle pesticide mixed with fertilizer after laid for 3 weeks, which indicated that the insecticidal effect of pesticide-added compound fertilizer was affected by laying.关键词
