Owing to the rise of the standards of living in our country, the qua-lity of wheat, which is one of the main food crops, has been increasingly important.In order to clarify the effect of nitrogen (N) and phosphorus(p)fertilization on grain yield, grain protein content and protein yield inwinter wheat,a field experiment with a strip plot design was conductedin Shenze Country,Hebei Province, during the 1985-1986 winter wheatgrowing season. Five N levels (0,4,8,12,16kg/mu), and four P levels (0,4, 8, 12kg/mn)...

Owing to the rise of the standards of living in our country, the qua-lity of wheat, which is one of the main food crops, has been increasingly important.In order to clarify the effect of nitrogen (N) and phosphorus(p)fertilization on grain yield, grain protein content and protein yield inwinter wheat,a field experiment with a strip plot design was conductedin Shenze Country,Hebei Province, during the 1985-1986 winter wheatgrowing season. Five N levels (0,4,8,12,16kg/mu), and four P levels (0,4, 8, 12kg/mn) were involved in the experiment, amounting to a total oftwenty treatments. The main results are summarized as follows.1) The effect of N fertilizer on grain protein content (%) was verysignificant statistically. The more N fertilizer was supplied, the higherthe grain protein content was. The effect of P and N×P interactions ongrain protein content were not significant.2) The effects of both N and P on grain yield and protein yield werevery significant. Also, the more N and P fertilizers were supplied, thehigher the grain yield and protein yield were.3) The N×P interaction on grain yield and protein yield were signifi-cant. Among 20 treatments (N×P combinations), the highest protein yieldwas given by the treatment N11×P8, them N12×P12 secondly;but thehighest grain yield was given by N12×P12, and N16×P8 secondly.Thelowest four grain yields and protein yields were obtained for the fourtreatment with no N supplying(No).4) Under N deficiency condition, P fertilizer had little effect on grainyield and protein yield. Under P deficiency condition, however, N fertili-zer can increase grain yield and protein yield, although not very signifi-cantly.5) Protein yield was closely related to both grain yield and grain pro-tein content, but the relation to grain yield was much closer(r=0.9805)than that to grain protein content (r=0.7667). This means that, it ismuch easier to increase protein yield by increasing grain yield than byincreasing grain protein content. Also the grain yield was closely relatedto grain protein content, which suggests that it is possible to realize thepurpose of combining the high grain yield and high grain protein contentin winter wheat, by means of suitable quantities and ratios of N and Pfertilization.

本文运用条区设计设置的试验结果,分析了氮磷化肥对籽粒产量、蛋白质含量和蛋白质产量的主效和互作。氮对三个指标的影响都极显著;磷对籽粒产量和蛋白质产量影响极显著,而对蛋白质含量无显著影响;氮磷对蛋白质含量的影响无显著交互作用,而对籽粒和蛋白质产量的影响都有显著互作效应。对籽粒产量和蛋白质产量进行综合分析,最优氮磷组合为N_(12)∶P_(12)或N_(16)_∶P_8(公斤/亩),就此还分析了氮、磷取不同水平时氮磷的最优组合问题。籽粒产量、蛋白质含量和蛋白质产量间两两呈极显著正相关;但蛋白质产量与籽粒产量的相关系数高于蛋白质产量与蛋白质含量的相关系数。说明通过提高籽粒产量比通过提高蛋白质含量来提高蛋白质产量较为容易。但也存在通过栽培措施使籽粒产量和蛋白质含量同时提高的可能性。

This paper examined the influence of data imbalance on the analysis results for random block design,split-plot design and strip-plot design using the Monte Carlo simulation.The simulation results showed that the imbalance of data due to missing observations led to lower precision and lower exactness of variance component estimation,to underestimation of the error of fixed effects as well as to higher type Ⅰ error rate for fixed effect test.With more missing observations these influences would...

This paper examined the influence of data imbalance on the analysis results for random block design,split-plot design and strip-plot design using the Monte Carlo simulation.The simulation results showed that the imbalance of data due to missing observations led to lower precision and lower exactness of variance component estimation,to underestimation of the error of fixed effects as well as to higher type Ⅰ error rate for fixed effect test.With more missing observations these influences would be heavier.The imbalance of data influenced the analysis results in split-plot design and strip-plot design much heavier than in random block design.

 利用蒙特卡罗(MonteCarlo)模拟考察了随机区组设计、裂区设计和条区设计因数据缺失形成的数据非平衡性对试验分析结果的影响。结果表明,数据非平衡性可导致方差组分估计的精准度降低、固定效应误差的偏低估计以及固定效应测验一类统计错误率的增大。缺失数据越多,这一现象表现越明显。数据缺失对随机区组设计分析精准度的影响小,而对裂区和条区设计分析精准度的影响大。

The newly-built embankments along the Liuxi River, Guangzhou were completely barren and, therefore, needed to be protected with appropriate eco-engineering measures. The riparian buffer strips of the river were destroyed, as a result it completely bare or covered by weeds. Therefore, it was in need of ecological modification with suitable herbaceous species. In order to effectively harness the riparian buffer strips of the river to form a new ecological landscape, a field experiment to screen appropriate species was carried out on a section of riverbank and two blocks of riparian buffer strips with different properties. Among the tried 5 herbaceous species on the riverbank, Eremochloa ophiuroides performed the best on the whole, followed by Paspalum notatum, Stenotaphrum helferi and Stenotaphrum secundatum, and Arachis pintoi the poorest. Later, the growth of all the 5 species, however, became poorer and poorer due to the excessively high temperature, less rainfall, and infertile and solid soil during the period July and August. On the rocky riparian buffer strips plot I, the tufty species, Paspalum giganteum, Eragrostis curvula, and Vetiveria zizanioides assumed better performance, but the prostrate A. pintoi, S. helferi, and P. notatum assumed poorer performance due to shorter roots and therefore prone to be washed away by flood. Regarding those plant species grown on the terrene riparian buffer strips plot II, they all grew good due to better soil fertility, and less submergence and flood. All in all, E. curvula, and P. giganteum had the best comprehensive performance on the riparian buffer strips, and V. zizanioides was also worth planting if considering it from the angle of submergence tolerance.

广州流溪河新筑的河堤完全祼露,河流两边的河岸缓冲带受到人类活动的破坏而成为裸露的砂石地或杂草丛生,二者都需要进行生态整治。为了对河流两岸进行生态改造,形成一种护坡效果好、景观效果佳的新流域景观,作者在一段河堤与两块不同性质的河岸缓冲带上进行了适宜草种的筛选试验。在河堤被测试的5个草种中,假俭草的综合表现最好,其次是百喜草,再次是钝叶草与森特钝叶草,野花生的表现最差。在砂石基质的河岸缓冲带样地I,丛生性的大雀稗、弯叶画眉草和香根草表现较好,而匍匐性的野花生、钝叶草和百喜草表现较差,这主要是后三者因根系浅,易遭洪水冲击。至于种植在土质的河岸缓冲带样地II上的草种,由于土质状况好,淹水时间短,普遍表现良好。总的来看,弯叶画眉草、大雀稗在河岸缓冲带上的综合表现最好,但如果从耐淹角度来考虑,香根草也应是一个较理想的草种。
