摘要:

针对新疆南疆地区风沙土土壤贫瘠问题,开展土壤固碳培肥试验。于2022—2024年在和田地区皮山农场开展大棚试验,一年种植春提早和秋延后两茬番茄,设置氮磷钾化肥+鸡粪(NPKJ)、氮磷钾化肥+牛粪(NPKN)、氮磷钾化肥+猪粪(NPKP)、氮磷钾化肥+玉米秸秆堆肥(NPKY)、氮磷钾化肥+沼渣(NPKZ) 和未添加有机物料的对照处理氮磷钾化肥(NPK)共6个处理,研究等碳量投入下不同有机物料对土壤团聚体、有机碳及其活性组分的影响。试验结果表明:各处理土壤以<0.053 mm粒级的微团聚体为主,对>0.25 mm团聚体影响不显著;施入有机物料各处理0~40 cm土层有机碳含量显著高于NPK处理,各处理间无显著性差异;各处理0~40 cm土壤活性有机碳含量显著高于NPK处理,其中NPKJ处理0~20 cm的土壤活性有机碳含量显著高于其他各处理,较NPK提高了110.42%,20~40 cm各处理无显著差异;有机物料投入后显著增加0~40 cm土壤微生物量碳含量,0~20 cm土层NPKJ处理显著高于其他各处理,较NPK提高202.78%,20~40 cm各处理土壤微生物量碳含量无显著差异;鸡粪处理下番茄产量显著高于其他处理,较NPK增产12.45%。综合有机物料对土壤固碳增产效果,鸡粪处理最优。

Abstract:

Aiming to solve the problem of poor sandy soil in southern Xinjiang, soil carbon sequestration and fertilization experiments were carried out. Six groups of control treatments were set up, including NPK fertilizer without organic materials, NPK fertilizer+chicken manure (NPKJ), NPK fertilizer+cow manure (NPKN), NPK fertilizer+pig manure (NPKP), NPK fertilizer+corn straw compost (NPKY) and NPK fertilizer+biogas residue (NPKZ), and the effects of different organic materials with equal carbon content on soil aggregates, organic carbon and their active components were studied. The results for two consecutive years showed that the micro-aggregates with a particle size of <0.053 mm were the main ones in each treatment, and the effect on the aggregates of >0.25 mm were not significant. In 0-40 cm, the organic carbon in treatments with organic materials had no significant differences, but they were significantly higher than that of the NPK treatment. The soil active organic carbon content of each treatment was significantly higher than that of NPK treatment at 0-40 cm, particularly in NPKJ treatment at 0-20 cm, which increased by 110.42% compared to NPK, and there was no significant difference between treatments of 20-40 cm. After the input of organic materials, the soil microbial biomass carbon content at 0-40 cm of each treatment was significantly increased as well, and the NPKJ treatment of 0-20 cm soil layer was much higher than that of other treatments, which was 202.78% higher than that of NPK, and no significant differences were witnessed among treatments at 20-40 cm. The yield of tomato under chicken manure treatment was significantly better than that of other treatments, which was 12.45% higher than that of NPK. Based on the experiments, chicken manure treatment had the best effect on soil carbon sequestration and yield increase.
