红壤区花生连作障碍现象普遍,严重制约着花生持续优质高产和稳产。通过田间小区试验,研究商品抗重茬制剂、发酵菜籽饼、自制生防细菌生物肥及内生真菌生物肥等4种施肥措施对连作花生病害发生、生长发育和产量的影响。研究结果发现4种施肥措施均明显降低了连作地花生根腐病的发病程度,其中发酵菜籽饼和自制生防细菌生物肥处理对连作地花生根腐病的防治效果最好。与常规NPK施肥相比,4种施肥措施均能明显增加连作地花生产量,其中发酵菜籽饼和生防细菌生物肥处理增产效果最好,分别增产23%和35%,具有广阔应用前景。
The continuous cropping obstacle of peanut in red soil area is a common problem, which seriously hampers the continuous high quality and stable yield of peanut. The field plot experiment was conducted to study the effects of four kinds of fertilization measures on the occurrence, growth and yield of peanut continuous crop peanut, including commercial anti-stubble preparation, fermented rapeseed cake, self-made biocontrol bacterial bio-fertilizer and endophytic fungi bio-fertilizer. The results showed that all the four fertilization measures significantly reduced the incidence of peanut root rot even after continuous cropping. The results showed that the best control effect of peanut root rot was by using fermented rapeseed cake and self-made biofertilizer. Compared with the conventional NPK fertilization, the four kinds of fertilization could significantly increase the yield of peanut in continuous cropping. The yield of peanut was increased by 23% and 35% respectively, which had wide application prospect.
