The results show that under crop rotation of wheat and maize in damp soil and brown soil, stalks return to fields integrated with applying potash fertilizer can keep K balance within a cycle and K return rate reaches 109.1%～111.9%, annual wheat stalks return to fields can provide 226.5～261.0 kg/hm2 K, meanwhile the K return rate reaches 95.2%～97.1% for only applying potash fertilizer; under crop rotation of wheat and soy bean in grittiness black earth, only applying potash fertilizer can also keep K balance within a cycle, its K return rate reaches 119.9%, meanwhile the K return rate reaches 142.0% for stalks return to fields integrated with applying potash fertilizer, which result from maize being much more absorption to K than soy bean.

在砂姜黑土区小麦+大豆轮作制度下，即使小麦秸秆不还田，仅施用化学钾肥，亦能维持小麦-大豆轮作周期钾素的平衡。施钾配合秸秆还田处理，钾归还率达142.0%，施钾且秸秆不还田处理钾归还率达119.9%。主要是大豆不象玉米那样带走较多的钾造成的。

High altitude region is more srious than low region. The armyworm imperilment degree varies in different crops. The field planted wheat as forcrop is serious. Also, different levels of cultivation management have evident effects on the imperilment degree of armyworms. For instance, the fields of rough management and bad crop growing suffered more serious imperilment than those of high quality management, intensive cultivation and good crop growing way.

5海拔高低不同，粘虫为害程度有显著差异，表现为高海拔地区较低海拔地区受害重；不同作物对粘虫发生为害程度影响较大，表现为前作为小麦的玉米受害重；耕作管理水平对粘虫发生为害程度有显著影响，表现为管理粗放、长势差的地块受害最重，而管理水平高，精耕细作，长势良好的玉米地受害轻。

Visual Rice Growth Models system represented an effort to design crop modeling software with object-oriented paradigm and to organize classes in system with model-document-view architecture. Firstly, the crop-environment system was abstracted as many subsystems and physiological processes with object-oriented paradigm while many classes were established to simulate the behaviors of these subsystems and physiological processes. In VRGM, the document-view architecture in Visual C++ was extended as model-document-view architecture for agricultural integrated system. In the model-document-view architecture, document gets the final simulation results by manipulating the models classes and acts as a communicating intermediacy between model and view. Views display the simulation results and translate users' operation and data entering to document. The architecture separates the domain models, data management and user interface.
