Effect of tillage and crop on arbuscular mycorrhiza colonization of winter wheat and triticale under Mediterranean conditions

Large‐scale inoculation with arbuscular mycorrhizal fungi (AMF) is generally impractical in most regions and we have little understanding of the factors that determine inoculation success. Nevertheless, the ability to take full advantage of indigenous AMF for sustainable production needs to be developed within cropping systems. We used part of a long‐term field experiment to understand the influence of tillage and the preceding crop on AMF colonization over the growing season. Arbuscular mycorrhiza colonization rate was more affected by treatment (tillage or the combination of crop and preceding crop) than by the total number of AMF spores in the soil. Conventional tillage (CT) had a statistically significant negative effect (P ≤ 0.05) on spore numbers isolated from the soil, but only in the first year of study. However, the AMF colonization rate was significantly reduced by CT, and the roots of wheat, Triticum aestivum, L, cv. Coa after sunflower, Helianthus annuus L., were less well colonized than were those of triticale, X Triticosecale Wittmack, cv. Alter after wheat, but the affect of tillage was more pronounced than was the effect of crop combination. Under no‐till there was a significant increase in AMF colonization rate throughout the sampling period in both wheat and triticale, indicating that the extraradical mycelium previously produced acted as a source of inoculum. In general, triticale showed greater AMF colonization than wheat, despite the preceding crop being less mycotrophic. Under these experimental conditions, typical of Mediterranean agricultural systems, AMF colonization responded more strongly to tillage practices than to the combination of crop and preceding crop.

施钾对青引1号燕麦草产量及根系的影响

在缺钾地区，开展了不同施钾对青引1号燕麦（Avena sativa cv. Qingyin No.1）干物质产量和根系的影响，找出最佳施钾量，为青海省燕麦种子生产提供依据。结果表明，在施N 54.75 kg/hm2和施P2O5 51.75 kg/hm2的基础上，施K2O 40 kg/hm2，青引1号燕麦开花期收获时可获得最高的干物质产量和蛋白产量，分别为29575.0和2099.8 kg/hm2，二者均符合Y=a+bK+cK2函数变化。施K2O 40 kg/hm2，青引1号燕麦株高、总分蘖数、根长和根数最大，分别为184.5 cm、3.22个/株、15.90 cm和26.17 条/株； 施K2O 20 kg/hm2时，植株茎粗和根量达最大，分别为0.585 cm和0.540 g/株。各产量性状、地下生物量以及饲草和蛋白产量间均存在显著或极显著正相关关系。
