The characteristics and functions of different unit-roots and their effects on the yield components in wheat were studied by means of 15N tracing technique.The root grouping was made by cluster analysis according to the function of different unit roots.The results were as follows:The unit-roots characters (weight, length etc. ) and 15N absorption decreased progressively downward. 15N absorbed by any unit roots could be transported from root to tiller and from tiller to tiller, but the transporting ratio was...

The characteristics and functions of different unit-roots and their effects on the yield components in wheat were studied by means of 15N tracing technique.The root grouping was made by cluster analysis according to the function of different unit roots.The results were as follows:The unit-roots characters (weight, length etc. ) and 15N absorption decreased progressively downward. 15N absorbed by any unit roots could be transported from root to tiller and from tiller to tiller, but the transporting ratio was different.The pattern was as follows: when 15N was offered to total roots of plant or only to primary roots, it was transported to main stem and then decreassingly to tillers from lower unit to upper one, when 15N was offered to n unit-root, it was transported to n unit tillers ( incuding main stem), then to n + 2 or n-2 unit tillers ( same side tillers) , followed by n + 1 or n -1 unit tillers (opposite tillers) , and finally to other unfeed roots.According to the function,the wheat roots could be divided into 3 gr-oups:primary root group,lower secondary root group and upper secondary root group.The ratio of 15N absorption to the total N absorption in each group was 26.7%, 31.4% and 41.9% respectively.The difference among the three groups were that the primary root group functioned throughout whole life of wheat, mainly promoting tillers and increasing root numbers before winter; the lower secondary root group played the major role in strenthening tillers and promoting ear development; the upper secondary root group had the main function in determining the floret number, kernel number and kernel weight.

应用(15)~N示踪技术研究了冬小麦不同单位根的特性、功能及对产量构成因素的影响。不同单位根的根干重、根长度及吸(15)~N量等,由下而上依次减少。各单位根吸收(15)~N后,蘖根之间,蘖蘖之间皆可互相运转,但其运转比例不同,其功能模式是:(15)~N喂全株根或专喂初生根,则先供给主茎,其次是分蘖,而且随蘖位升高而递减;喂n单位根,则先供给n单位本身(包括主茎),其次是n+2或n-2单位的蘖(同侧蘖),然后是n+1或n-1单位的蘖(对侧蘖),最后是未喂(15)~N的根系。依照各单位根的功能,小麦根可分为3组:初生根组、次生根下位组和次生根上位组。各组根吸收肥料氮量占总氮量的百分比分别是26.7%、31.4%和41.9%。各组根的主要功能是:初生根组在小麦一生中都起重要作用,但主要是促进冬前分蘖;次生根下位组对巩固分蘖,促进穗部发育起主要作用;次生根上位组对提高结实率、籽粒灌浆起决定作用。

The development of secondary porosity of sandstones has evidence law at deep burial strata of Shahejie Formation in eastern and western depressions of Liaohe oil field. The eastern depression has three secondary porosity zones in vertical, but western only two. The secondary porosity zone of the second member lower to the third member top of Shahejie Formation, viz the upper secondary porosity, is the result of leached by surface fresh water and integrated process along unconformity interface later period...

The development of secondary porosity of sandstones has evidence law at deep burial strata of Shahejie Formation in eastern and western depressions of Liaohe oil field. The eastern depression has three secondary porosity zones in vertical, but western only two. The secondary porosity zone of the second member lower to the third member top of Shahejie Formation, viz the upper secondary porosity, is the result of leached by surface fresh water and integrated process along unconformity interface later period by inorganic acid in open water circulation. The mechanism of lower two zones of secondary porosity is similar to two secondary porosity in western depression which silicate mineral had been made solution by organic acid in seal water circulation. The geological conditions of these two zones forming are following as: temperature is about 100 to 130 Celsius, pressure coefficient is 1.2 to 1.3 around, the phase and depth are during source rock had made abundant expulsion hydrocarbon.

辽河油田东、西部凹陷深层沙河街组砂岩次生孔隙的发育有着明显的差异,东部凹陷为3 个次生孔隙发育带,而西部为2 个;东部凹陷沙二下部- 沙三段顶部的次生孔隙带,即上部次生孔隙发育带,主要是受地表淡水淋滤和后期沿不整合面的开启性水循环综合作用的结果,而下部两个带与西部凹陷的两个次生孔隙发育带的形成机理类似,为封闭性水循环的有机酸水溶液对硅酸盐矿物的溶解作用所致。其形成的地质条件是温度100~130℃,压力系数1.2~1.3±,烃源岩大量排烃的阶段和深度。

The deflected secondary air system has been widely used in the large capacity utility boilers.In such a system,the lower secondary air is deflected to the waterwall and the upper secondary air and the overfire air are deviated to the opposite direction of the flow rotation direction in the furnace,in order to obtain the effect of slagging perevention and decreasing the twisting residual at the exit of the furnace.In this paper,through the numerical methods,the slagging prevention property of a 600 MW...

The deflected secondary air system has been widely used in the large capacity utility boilers.In such a system,the lower secondary air is deflected to the waterwall and the upper secondary air and the overfire air are deviated to the opposite direction of the flow rotation direction in the furnace,in order to obtain the effect of slagging perevention and decreasing the twisting residual at the exit of the furnace.In this paper,through the numerical methods,the slagging prevention property of a 600 MW utility boiler with a deflected second system is calculated on the basis of the simulation of flow field,temperature field,solid and gas combustion and the deposit growth under slagging conditions.The results illustrate that the numerical methods used in this paper is feasible and it can give reference to the design and operation of a high capacity utility boiler with deflected secondary air system.

偏转二次风系统已广泛应用于大型四角切圆燃烧锅炉 ,用以抑制炉内结渣 ,防止水冷壁高温腐蚀等。为降低炉膛出口扭转残余 ,通常采用下部二次风大角度正切、上部二次风和 OFA风反切的布置方式。本文对某台采用偏转二次风系统的 6 0 0 MW燃煤四角切圆燃烧锅炉的炉内结渣过程进行模拟 ,对炉内气固相流动、温度场、气固相燃烧、固相向水冷壁的输运过程和灰粒在水冷壁上的粘附生长过程进行了数值模拟 ,结果表明 ,偏转二次风系统具有较强的防结渣性能 ,这一点也被锅炉的实际运行所证实
