With the rapidly developing of Internet of Things (IoT), the volume ofdata generated by IoT systems is increasing quickly. To release the pressure ofdata management and storage, more and more enterprises and individuals preferto integrate cloud service with IoT systems, in which the IoT data can be outsourced to cloud server. Since cloud service provider (CSP) is not fully trusted,a variety of methods have been proposed to deal with the problem of data integritychecking. In traditional data integrity audition schemes, the task of data auditing isusually performed by Third Party Auditor (TPA) which is assumed to be ***, in real-life TPA is not trusted as people thought. Therefore, theseschemes suffer from the underlying problem of single-point failure. Moreover,most of the traditional schemes are designed by RSA or bilinear map techniqueswhich consume heavy computation and communication cost. To overcome theseshortcomings, we propose a novel data integrity checking scheme for cloud-IoTdata based on blockchain technique and homomorphic hash. In our scheme, thetags of all data blocks are computed by a homomorphic hash function and storedin blockchain. Moreover, each step within the process of data integrity checking issigned by the performer, and the signatures are stored in blockchain through smartcontracts. As a result, each behavior for data integrity checking in our scheme canbe traced and audited which improves the security of the scheme greatly. Furthermore, batch-audition for multiple data challenges is also supported in our *** formalize the system model of our scheme and give the concrete *** performance analyses demonstrate that our proposed scheme is efficientand practical without the trust-assumption of TPA.

为探究有机无机肥配施对精量穴直播水稻产量及氮素利用的影响,2018—2020年,选用鸡粪型有机肥进行不同比例有机肥替代化肥田间小区试验。试验采用两因素裂区设计,主区为3个杂交水稻品种,分别是宜香优1108、F优498、德优4727;副区为不同比例有机肥替代化肥,在总施氮量150 kg·hm-2水平下,设置100%化学N肥(M1)、75%化学N肥+25%有机肥(M2)、50%化学N肥+50%有机肥(M3)、25%化学N肥+75%有机肥(M4)和100%有机肥(M5)共5个处理,以不施N肥为对照(CK)。结果表明,随着有机肥比例的增加,3个品种的每穗粒数和产量均先增加后降低。对于宜香优1108,M2处理的每穗粒数最多、产量最高,2018、2019和2020年分别较M1处理增产2.92%、5.53%和8.07%。对于F优498和德优4727,M3处理的每穗粒数最多、产量最高,3年分别较M1处理平均增产9.13%、7.33%、7.21%和2.7%、6.03%、8.69%。施肥处理中均以M5处理的产量最低。对于氮素转运率,M2和M3处理水稻的氮素转运率增加,其中,宜香优1108在M2和M3处理下氮素转运率3年平均较M1处理提高9.40%和11.41%,F优498提高9.63%和19.18%,德优4727提高9.40%和18.03%。随着有机肥比例的增加,氮素表观利用率降低,氮素收获指数、氮素农学利用率和氮肥偏生产力均先增加后减少。宜香优1108在M2和M3处理下氮素收获指数3年平均较M1处理提高5.05%和5.54%,F优498提高4.53%和8.80%,德优4727提高4.88%和8.98%。由此表明,在精量穴直播下,有机肥与无机肥的合理配施能更好地调控水稻对养分的吸收利用,从而提高产量;宜香优1108采用25%有机肥替代化学氮肥时产量最佳,而F优498和德优4727采用50%有机肥替代化学氮肥增产效果更好。
