In order to determine the genetic differences between high molecular weigh glutenin subunits 17+18 and 7+8, HMW-GS 17+18 was introduced into Longmai 20 by 6 consecutive backcrosses with biochemical marker assisted selection. The near isogenic lines of HMW-GS 17+18 and 7+8 were obtained and grown in the experimental field of Crop Breeding Institute of Heilongjiang Academy of Agricultural Sciences in 2006. The field experiments were designed using the method of two line-contrast arrangement with four replicates.

为了解小麦Glu-B1位点HMW-GS 17+18与7+8的遗传差异，利用生化标记和连续6次选择性回交的方法将17+18亚基转移到黑龙江省小麦品种龙麦20中，获得了龙麦20的Glu-B1位点HMW-GS17+18与7+8的近等基因系。2006年将NILs种植在黑龙江省农业科学院育种研究所的试验田，田间设计采用双列对比排列，4次重复。

This model considered many factors affecting the growth of maize, such as irrigation, rainfeed, CO_2 fertilization and predating the planting date by 5 days and 10 days when analyzing the change of yield and period duration. It further indicated how the production of maize was affected by the increase of CO_2 and PAR by using the data collected from the field experiment in Changping Experimental Station of China Agricultural Academy of Sciences.

模拟时分别考虑了灌溉、雨养、CO_2的肥效作用、播种期提前5天和10天条件下玉米的产量和生育期的变化情况，同时利用在中国农业科学院昌平试验站所做的田间试验结果进一步说明CO_2升高以及光强增加对玉米生产的影响情况。

炒一盘香喷喷的回锅肉，凉拌一份从田间摘回的野生侧耳根，煮一盆豌豆尖豆腐汤，呷两口小酒，在有滋有味的菜肴中品出百味人生，人生百味，其怡然自得的滋味让人想起孔子的描述：&饭疏食、饮水，曲肱而枕之，乐亦在其中也！&

Testified by some research results and field experiments, it is shown that the model is reasonable and has some advantages, such as strict physical foundation, simple calculation and solution, higher accuracy. So it can be used to decide the reasonable technical indexes of border irrigation.

结合已有文献资料和田间试验对模型进行检验，表明所提出计算下渗水形状系数的简化公式和经验公式是可靠的，以此建立的水流推进简化模型具有严谨的物理基础，且计算求解方便、精度较高，可用于畦灌合理灌水技术指标的确定。

There was no impact on cotton aphid and ALB by Bt-cotton, but the ingesting sap behavior in pholem and the intrinsic rate of increase of the aphids fed on transgenic Bt CpTI cotton decreased significantly.

同时，田间棉铃虫上灯蛾的FA值与Bt棉的种植年代间存在着显著的负相关，显示出棉铃虫自然种群对Bt棉的适应性随着Bt棉种植时间延长而渐增的趋势。

In order to attain high accuracy of GPS satellite navigation, positioning and low cost in precision agriculture, it is studied a method of GPS Pseudo-range observation and Carrier phase measurement to combine the actual conditions of agriculture. It is presented a method of high accuracy positioning and measure based on GPS OEM board in this paper, and proved the feasibility of key technology with emulations and field tests.

在田间隔离昆虫传染的条件，于小米不同生长期所进行的人工分期接种试验，证明接种期愈早对植株的生长和产量的影响愈大，并发现根系受红叶病毒的影响最为显著。

Total RNA was isolated from phloem of young shoots and retro-transcripted to cDNA by RT-PCR with specific primers, and the amplified cDNA fragments were sequenced for identification of subtypes. An effective RT-PCR technique was established for detecting citrus viroid types, and three types were recognized, i.e.

以田间柑橘枝条韧皮部为试材，提取总RNA，反转录成cDNA，再用不同类型类病毒的特异引物进行PCR扩增，鉴定出各个样品所携带的柑橘类病毒类型；通过测序分析各类型的序列，并与国内外报道的序列进行同源性分析，确定所测样品的亚型。

The methods of field experiment, simulation experiment and analysis were used to study the effects of the different measures (i.e., mulching, fertilization and irrigation) to control the supply of water and nutrients on nutrient uptakes, accumulations and translocation of winter wheat; and their relationship with the accumulations of dry matter and water use efficiency were also analyzed.

因此，本研究以冬小麦为供试作物，采用田间试验、模拟试验和室内分析等相结合的研究方法，探讨了不同水肥调控技术措施对小麦生长发育过程中养分吸收、累积和转移等的效应，及其与干物质累积、水分利用效率等间的关系，并从土壤养分和水分的动态变化、根系生长和生理代谢指标的测定3个方面分析了其机理。

Delineation result based on the improved ant clustering indicated that the study area could be partitioned into two irrigation management zones. Soil field capacity, saturation moisture content and permanent wilting point in Zone I were greater than those in Zone II, which indicated that soil in Zone I had stronger drought resistance than that in Zone II under the same climate conditions. Delineation of irrigation management zones could provide references and data support for site-specified irrigation management.
