The effects of different chemical fertilizer combinations (N, P and K) oncrop yield, N uptake and nitrate distribution and accumulation to a depth of 100 cm were studied ina cinnamon fluvo-aquic soil profile (Beijing) with a continuous winter wheat-summer maize croppingsystem for nine years. The experiment consisted of 7 treatments: no fertilizer control (CK); Nalone, N in combination with K (NK), P (NP), and P and K (NPK and N1PK); and P and K in combinationwithout N (PK). The rate of N was 150 kg ha^(-1) for the N treatments except Treatment N1PK withhigher N rate (195 kg ha^(-1)), and the rates of P (P_2O_5) and K (K2O) were 75 and 37.5 kg ha^(-1),respectively. The applications of N combined with P and K (NK, NP and NPK) resulted in higher cropyields than a single application of N. The yields followed the order: NPK > NP > N1PK > PK > NK > N> CK for winter wheat, and NPK > N1PK > NP > NK > N > PK > CK for summer maize. Supplement of N withP or K, or both P and K resulted in a higher average N uptake of the two crops, which was in adecreasing order NPK > NP > N1PK > NK > N > PK > CK. The combinations also increased apparent Nrecovery more than N alone and CK. The nitrate content in the profile was thus reduced more in thecombination treatments. The nitrate accumulation in the soil profiles followed the order: N > NK >N1PK > NPK > NP > CK > PK. Higher N uptake by the adequately fertilized crops (Treatment NPK)reduced nitrate accumulation in the profile and thus reduced nitrate leaching. The optimum N:P:Kratio was thus of paramount importance in increasing yields and N uptake of crops and reducingnitrate leaching losses.

Splenic hamartoma is a benign malformation composed of an anomalous mixture of normal splenic elements.1 Approximately half of the patients with the tumor are asymptomatic and diagnosed accidentally by autopsy or splenectomy. The tumor-related renal hematological and dermatological abnormalities can be treated by removal of the tumor. Splenic hamartoma which is related to renal diseases including extramembranous glomerulonephritis, membranoproliferative glomerulonephritis and renal adenocarcinoma has been reported previously.

在测定土壤养分中,可见-近红外光谱技术具有很大的应用空间。该研究探讨了基于可见-近红外光谱(250~950nm)离线、快速测定土壤总氮(TN)、总磷(TP)、总钾(TK)、总碳(TC)等土壤养分的方法及应用。采集青岛三个不同地区土壤样品(异质性较高的山地土壤与河畔土壤)各60份,总计180份,并测定其TN,TP,TK,TC含量及其可见-近红外反射光谱,利用Kennard-Stone法按2∶1比例划分校正集和检验集,采用遗传算法分别提取TN,TP,TK,TC特征波长,以偏最小二乘法建立定量分析模型。TN,TP,TK,TC含量所建光谱模型的相关系数分别为0.970,0.964,0.680和0.967,检验集的相关系数分别为0.980,0.937,0.717和0.972,检验集的RPD值分别为4.570,2.424,1.411和4.135。结果表明,该方法能够对土壤TN,TP,TC含量进行精确预测,对土壤TK含量进行粗略预测。该研究主要依靠可见光波段,较好的预测了异质性较高的土壤的氮磷钾等养分含量,有望降低未来土壤养分速测的成本。此外,该研究还提供了青岛土壤养分的光谱库,为我国土壤大数据库的建立提供技术支撑。

[目的]林木树冠结构与密集度具有一定关联性。密度效应一直是森林经营关注的问题,本研究通过探究蒙古栎次生林林分密度与树冠结构、密集度的关系,以期深入掌握蒙古栎次生林结构特征,为蒙古栎林可持续经营提供充分的科学依据。[方法]于2020年8月在小陇山蒙古栎次生混交林中选取立地条件均一、不同密度的典型样地进行调查,采用最小显著性差异法、Pearson相关系数和最优结构方程模型,分析不同密度下树冠结构与密集度的关系。[结果]不同密度蒙古栎林中树冠体积的变异最强,其次为冠长与树冠面积,冠幅、冠长率和冠形率的变异最弱,树冠结构特征的变化趋势随林分密度的改变呈单峰型分布。随着林分密度递减,冠幅、树冠面积、树冠体积分别与胸径的相关性趋势近似于“L”型,而冠长和胸径的相关性趋势与林分密度的变化保持了一致,林分密度对冠长率、冠形率与胸径相关性的影响不大。蒙古栎林密集度处于中等密集至很密集状态,但不同密度林分内林木树冠的挤压与重叠程度有差异,其中优势树种蒙古栎、白桦、华山松和椴树起了决定性作用。蒙古栎林中林分密度对树冠结构与密集度关系的影响包含两种路径:林木竞争—树冠结构共同介导的间接影响;林木竞争—胸径—树冠结构共同介导的间接影响。[结论]不同密度蒙古栎林树冠结构有差异,树冠结构特征与林木胸径有关,林分密度影响了蒙古栎林树冠结构与密集度的关系。要实现蒙古栎林的可持续经营,不仅要考虑林木胸径大小,更要关注林木树冠结构特征,通过调整林分密度可优化树冠结构,改善林冠层挤压状况,以促进森林更新与增加物种多样性。
