摘要

根结线虫（Root-knot nematodes， RKN）尽管具有营养价值，但在世界范围内严重降低西瓜产量。研究了岩尘（RD）和禽粪（PM）改良剂单独或联合施用对西瓜果实RKN的抑制和增产效果。采用3个重复的随机完全区组设计进行了2个试验。处理包括分别以0、2.5或5吨/公顷施用RD和PM，以及分别以2.5或5吨/公顷施用RD和PM。接种后60 ~ 66 d，测定根蚀、RKN种群密度和根冠重。结果表明，在第1和第2个试验中，与对照区相比，RD和pm联合处理的西瓜根瘤病分别减少了60 - 85%和67 - 89%。同样，在两个试验中，RKN种群在处理区被抑制了94 - 99%，与对照区不同。西瓜产量显著提高(p <；与对照区相比，RD和PM联合处理地块的产量分别为24.7 ~ 33.7 t/ha和34.6 ~ 46.5 t/ha，第一次和第二次试验分别为13.5 t/ha和20.9 t/ha。综上所述，RD和PM配施能有效降低RKN危害，提高西瓜产量，为西瓜生产提供了可持续策略。

Rock dust and poultry manure amendments suppress root-knot nematodes and enhance fruit yield in watermelon fields

Root-knot nematodes (RKN) severely reduce watermelon yields worldwide, despite its nutraceutical value. This study investigated the effects of rock dust (RD) and poultry manure (PM) amendments, applied singly or in combination, on RKN suppression and watermelon fruit yield enhancement. A two-trial field experiment was conducted utilizing a randomized complete block design with three replicates. The treatments included RD and PM each applied at 0, 2.5, or 5 t/ha and combined applications of RD and PM at 2.5 or 5 t/ha each. At 60–66 days post-inoculation, root galling and RKN population density were assessed alongside root-shoot weight. The results indicated that root galling in watermelons was reduced by 60–85 % and 67–89 % in the combined RD- and PM-treated plots across the 1st and 2nd trials, respectively, in contrast to the control plots. Likewise, the RKN population was suppressed by 94–99 % in treated plots in both trials, differing from the control plots. Notably, watermelon fruit yield was significantly higher (p < 0.05) in combined RD and PM treated plots, ranging from 24.7 to 33.7 t/ha and 34.6–46.5 t/ha in the 1st and 2nd trials, respectively, compared to control plots with 13.5 t/ha in the 1st trial compared to and 20.9 t/ha yield in the 2nd trial. In conclusion, our study indicates that co-application of RD and PM effectively reduced RKN damage and enhanced watermelon fruit yield, providing a sustainable strategy for watermelon production.

期刊介绍： The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
