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。

In engineering application, we think that the rock laboratory experiments may simulate and reshow rock bursts considering the conditions of coupled static-dynamic loads and rock burst and their comparison. Energy demand of rock burst occurring is revealed through analyzing energy transition of rock failure process under coupled static-dynamic loads. At the same time, the rule of energy utilization under coupled static-dynamic loads is discovered; the measures for rock cracking by utilizing high stress condition in deep rock mass and energy utilization improving are found.
