摘要
研究结果表明,3:2式麦椒间套,在小麦与辣椒共同生长期间,椒田日平均气温增加0.5℃,土壤相对湿度降低16.5％,辣椒采光时间缩短60.6％,黄色诱牌及辣椒上的有翅蚜着落量分别降低87.2％、80.8％。减轻了蚜虫对辣椒的直接为害及传播病毒病。间套田病毒病病株率较对照下降76.5％,病情指数减轻93.1％,每ha收入增加4853.4—11133.0元。缓解了辣椒与粮棉争地的矛盾,为辣椒生产开辟了新途径。
In comparison with pepper monoculture, the mean temperature, soil relative humidity, daylighting time and alighted alatae amount in pepper rows of 3 (rows of wheat): 2(rows of pepper) pattern wheat-pepper interplantation field were 0. 5℃ increased and 16. 5% ,60. 6% and 87. 2% decreased. The damage and virus transmission of aphid to pepper were alleviated. The incidence and index of virus disease were 76. 5% and 93. 1 % reduced, and the income of pepper cultivation was 4853. 4 - 11133. 0 yuan/ ha enhanced. Furthermore, the acreage incompatibility among pepper, cereals and cotton was relieved by this new pepper growing pattern.
