| 1. | Study on the occurrence rules of rice planthoppers in rice field with cultural crab
养蟹稻田稻飞虱发生规律研究 |
| 2. | Occurrence of rice planthoppers in single - cropping of rice fields in northern part of zhejiang province
稻区稻飞虱发生特点与原因探讨 |
| 3. | The occurring stage of rice planthopper in the paddy with or without cultural crab was similar
养蟹田和非养蟹田稻飞虱的发生期基本一致。 |
| 4. | The relationship of the distribution of rice planthopper and the distance of crab breeding line in the paddies with cultural crab was markedly positive
养蟹田稻飞虱的分布与距养殖沟的距离呈显著的正相关。 |
| 5. | The occurrence rules of rice planthopper in rice field with cultural crab was ascertained through systemic investigation and field census
通过系统调查和大田普查相结合的方法，研究明确了养蟹稻田稻飞虱的发生规律。 |
| 6. | Owing to the controlling of crab to the rice planthopper , the number of rice planthopper was obviously less than that of the control paddies without used pestcide , and in general years , the rice planthopper can be controlled by cultural crab and without appling pestcide
由于螃蟹对稻飞虱的控制作用，养蟹稻田稻飞虱的发生量比不施药对照田明显偏低，一般发生年份，不用药防治，即可控制稻飞虱的为害。 |
| 7. | Abstract : the results of field experiment of comparison and demonstration in a large area showed that treating seed with imidacloprid and applying it in the late seedling stage and the early field stage can control small brown - back rice planthopper better , and prevent the epidemic of rice black - streaked dwarf virus disease effectively
文摘:通过田间对比试验和大面积示范应用证明，播种时以吡虫啉拌种，秧田后期、本田前期喷施康福多、扑虱灵，可以较好地控制灰飞虱，从而有效地控制黑条矮缩病的流行。 |
