To estimate the quantitative genetic parameters of nitrogen use efficiency, twenty maize single-cross hybrids with varying nitrogen use efficiency were tested at two locations in the North China Plain. At both locations, the hybrids were grown under high (HN, 225 kg/hm^2 N) and low N levels. And no N fertilization on the LN field have lasted two years.

By utilizing the micrometeorology data of net radiation, soil heat flux, and CO2 concentration at two heights, temperature, relative humidity, and wind speed measured by the Japanese and Chinese cooperation team at Naiman District of Inner Mongolia, this paper presents a study of the characteristics of CO2 flux and concentration from different ecosystems (namely dune, grassland, light grazing site, medium grazing site, heavy grazing site, maize field and soybean field).

本文利用1993～1994年日本国家农业环境研究所与中国科学院沙漠研究所合作在内蒙古奈曼地区实测的7种不同生态系统（沙丘、轻度放牧草原、中度放牧草原、重度放牧草原、无放牧草原、玉米田和大豆田）的净辐射、土壤热通量、两个高度的CO2浓度、温度、湿度和风速等资料，采用空气动力学方法，计算了CO2通量及其与环境和人为干扰因子的关系，并分析了不同下垫面的光合作用特征。

The difference in mean genetic distance between special and normal maize was at 0.01 significant level.

特用玉米自交系间的遗传距离与普通玉米自交系间的遗传距离差异达到0.01的极显著水平。

Shading experiments were designed according to low light intensity problem caused by intercropping system of peanut with maize or wheat et al. Fenghua1 and Fenghua2 were adopted in the experiment of four light intensity levels (CK in which the plants were grown under natural light, 27% shading, 43% shading and 77% shading), which carried out at three growth stage using black sunshade net. And the three stages were seedling phase, pod-setting phase and pod-maturing phase. The aim of this study was to investigate the effects of low light on the photosynthetic characteristics, luminous energy distribute of PSⅡ, RuBPCase activitiy, plant morphogenesis, dry matter production, pod yield and quality of peanut at different stages, defined the relationship between dry matter accumulation and PAR, relationship of efficiency for solar energy utilization and PAR, and then set up the ...dry matter production and yield formation model on the basis of the experimental data.

针对花生与玉米、小麦等作物间作、套种造成遮光问题，选用大花生品种丰花1号和小花生品种丰花2号做为供试材料，在花生苗期、结荚期和饱果期分别用不同透光率的遮阳网进行遮光处理模拟弱光条件，设置自然光、遮光27%、遮光43%和遮光77%四种光强水平，研究了光强处理对花生光合特性、光系统Ⅱ光能分配、RuBPCase活性、植株形态建成、物质生产和产量以及品质的影响，明确了不同时期干物质积累及光能利用率与光合有效辐射的关系，以此为基础采用2种方法建立了花生干物质生产动态模型和花生产量形成模拟模型，并对各模型的模拟精度进行了比较。
