摘要
研究了稻田秸秆与微生物接种剂的原位混用对小麦产量的影响。在播种前15天，将当地可用的废弃水稻秸秆(切碎至3-5厘米)在冲积沙质壤土中加入或不加入嗜酸性纤维素分解真菌接种物(绿色木霉)，接种量为11.2吨/公顷。分别用游离固氮菌(固氮细菌)和磷酸盐增溶剂(纹状假单胞菌)对种子进行杀菌。在秸秆改良土壤中，单种微生物接种剂与尿素和磷矿肥(N = 60 kg hm - 1)和P2O5 (60 kg hm - 1)配施对小麦产量有显著影响。3种微生物联合接种对小麦产量均有抑制作用。
The effects of microbial inoculation on the yield of wheat when grown in straw-amended soil
A study was conducted to assess the effect of in-situ incorporation of paddy straw along with microbial inoculants on the yield of wheat crops. Locally available, waste, paddy straw (shredded to 3–5 cm) was incorporated with and without a mesophilic cellulolytic fungal inoculum (Trichoderma viride) in alluvial sandy loam soil at 11·2 tonnes ha−1 15 days prior to sowing. Seed bacterization with a free-living nitrogen-fixer (Azotobacter chroococcum) and phosphate solubilizer (Pseudomonas striata) was done in the respective treatments. Application of a single microbial inoculant in combination with two fertilizers, urea and rock phosphate at 60 kg N ha−1 and 60 kg P2O5 ha−1, respectively, produced a significant effect on the yield of wheat grown in straw-amended soil. Combined inoculation with all the three organisms had a repressive effect on the yield of wheat.
