摘要:

针对日光温室蔬菜栽培过量施用化肥和西北地区种养废弃物产生量大的问题,以羊粪、尾菜、牛粪、菇渣、玉米秸秆等种养废弃物为原料,设计8个配方进行好氧堆肥,以不施肥(CK1)和当地商品有机肥(CK2)为对照,除CK1外,其余处理按6 000 kg·hm-2的施用量作基肥施入,研究不同堆肥对日光温室西葫芦养分利用和土壤性质的影响。结果表明,与CK2相比,羊粪、尾菜、秸秆按6∶3∶1的质量比混合堆肥的处理(T4),羊粪、尾菜、菇渣、秸秆按6∶2∶1∶1的质量比混合堆肥的处理(T7),其西葫芦干物质积累量分别显著(P<0.05)提高14.69%、9.97%,产量分别显著提高23.12%、18.01%。氮、磷、钾肥利用率以T4处理最高,分别较CK2处理显著提高了8.19、12.24、14.38百分点。T4处理显著提升了果实中的氮、磷、钾含量,T7处理显著提升了根中的氮、磷、钾含量。此外,T4和T7处理的土壤有机质、碱解氮、速效磷、速效钾含量亦较CK2显著增加。综上,T4处理的效果最佳,有利于西葫芦最大限度地吸收利用养分和促进营养物质向果实的分配转移,同时可以有效改善土壤理化性质,从而最终获得高产。

Abstract:

In view of the excessive application of chemical fertilizers in greenhouses vegetables production and the large amount of planting and breeding waste in northwest China, planting and breeding wastes, such as sheep dung, vegetable waste, cow dung, mushroom residue, straw, were used in 8 recipes of aerobic composting. The treatment without fertilization application and the treatment with local commercial organic fertilizer were set as controls, and were denoted as CK1 and CK2, respectively. Except CK1, 6 000 kg·hm-2 composting products were applied in the other treatments, respectively, as the base fertilizer. The effects of treatments on nutrient utilization of zucchini and soil properties were studied. Compared with the CK2 treatment, the dry matter accumulation of zucchini under T4 (co-composting of sheep dung, vegetable waste and straw at a mass ratio of 6∶3∶1) and T7 (co-composting of sheep dung, vegetable waste, mushroom residue and straw at a mass ratio of 6∶2∶1∶1) was significantly (P<0.05) increased by 14.69% and 9.97%, respectively. The yield of zucchini under T4 and T7 was significantly increased by 23.12% and 18.01%, respectively. The nitrogen, phosphorus and potassium fertilizer utilization rates were the highest under the T4 treatment, which were significantly higher than those under CK2 by 8.19, 12.24 and 14.38 percentage points, respectively. The nitrogen, phosphorus and potassium contents in the fruit were significantly increased under T4 treatment than those under CK2, whiles the nitrogen, phosphorus and potassium contents in the root were significantly increased under T7 treatment than those under CK2. Besides, the contents of soil organic matter, alkaline hydrolysis nitrogen, available phosphorus and available potassium were significantly increased under T4 and T7 treatments. It was concluded that T4 treatment showed the best performance, as it was conducive to maximize the nutrient uptake and utilization capacity of zucchini, promote nutrients translocation to the fruit, as well as effectively improve soil physiochemical properties, hence to increase yield.
