摘要: 针对内蒙古阴山北麓旱作区作物水分利用率低和土壤保水能力差等问题,探求旱作区有机培肥改土管理措施,对马铃薯土壤蓄水和作物耗水形成优化方案。通过两年田间随机区组试验,设置传统施肥(CK)、化肥减量配施羊粪(NPK+SD)、化肥减量配施生物炭(NPK+B)、化肥减量配施微生物菌肥(NPK+MF)共4个处理,分析化肥减量配施有机肥对促进马铃薯生长发育、优化生育阶段耗水比例、提升水分利用效率的影响。结果表明:(1) NPK+MF处理下干物质积累量在淀粉积累期达到最大,较CK显著提升41.58%;NPK+MF处理下,增加了0~60 cm土层的土壤含水率,提高了土壤贮水量,同时增大了马铃薯生育期耗水量6.56%;播种-苗期阶段NPK+MF处理下平均耗水量、耗水模系数和耗水强度分别较CK显著降低14.61%、21.84%和14.60%;在块茎形成-膨大阶段耗水达到最大,该阶段NPK+MF处理下平均耗水量、耗水模系数和耗水强度比CK显著提高9.17%、3.34%和9.17%。(2) 相比于CK,NPK+MF处理下平均单薯重、单株结薯重和商品薯率分别显著增加了15.42%、25.57%和29.67%。NPK+MF处理下与CK相比产量、水分利用效率和经济效益分别显著提高了25.52%、17.81%和30.59%;较NPK+SD处理下分别显著提高13.26%、8.72%和14.41%,较NPK+B处理下分别显著提高了12.26%、8.42%和7.52%。可见,在内蒙古阴山北麓旱作区马铃薯生产中,化肥减量配施微生物菌肥措施不仅能调节马铃薯生育阶段耗水比例,一定程度上缓解马铃薯植株后期对水分的需求,还可以增加单位耗水下的产量。

Abstract:

Aiming at the problems of low water use efficiency of crops and poor water retention capacity of soil in dry farming area in the northern foot of Yinshan Mountain, the optimization scheme of soil water storage and crop water consumption of potato by organic fertilization and soil improvement management measures in dry farming area was explored. Through two years of field randomized block experiment, four treatments were setup: traditional fertilization (CK), chemical fertilizer reduction combined with sheep manure (NPK+SD), chemical fertilizer reduction combined with biochar (NPK+B), and chemical fertilizer reduction combined with microbial fertilizer (NPK+MF). The effects of chemical fertilizer reduction combined with organic fertilizer on promoting potato growth and development, optimizing water consumption ratio at growth stage and improving water use efficiency were analyzed. The results showed that the dry matter accumulation of NPK+MF treatment reached the maximum at the starch accumulation stage, which was significantly increased by 41.58% compared with CK. The NPK+MF treatment increased the soil moisture content of 0-60 cm, increased the soil water storage, and increased the water consumption of potato growth period by 6.56%. The water consumption of potato stage reached the maximum at the tuber formation-expansion stage. The average water consumption, water consumption modulus and water consumption intensity of NPK+MF treatment were significantly lower than those of CK by14.61%, 21.84% and 14.60%, respectively.The average water consumption, water consumption modulus coefficient and water consumption intensity of NPK+MF treatment were significantly increased by 9.17%, 3.34% and 9.17% compared with CK in the tuber formation-expansion stage. Compared with CK, the average single potato weight, single plant tuber weight and commodity potato rate of NPK+MF treatment were significantly increased by 15.42%, 25.57% and 29.67%, respectively. Compared with CK, the yield, water use efficiency and economic benefit of NPK+MF treatment were significantly increased by 25.52%, 17.81% and 30.59%, respectively. Compared with NPK+SD treatment, the yield, water use efficiency and economic benefit of NPK+MF treatment were significantly increased by 13.26%, 8.72% and 14.41%, respectively. Compared with NPK+B treatment, they were significantly increased by 12.26%, 8.42% and 7.52%, respectively. In conclusion, in potato production at the northern foot of the Yinshan Mountain region of Inner Mongolia, the strategy of reducing chemical fertilizer application combined with microbial fertilizer not only regulates the water consumption ratio across potato growth stages, partially alleviating the water demand pressure during the late growth period, but also enhances yield per unit of water consumption. This approach represents an effective soil fertility management solution for the region.
