| Abstract | From the morphological characteristics of crop growth, the mechanism model of photosynthate distribution based on the dynamic relationship between root, shoot, leaf and grain is proposed in this paper. And the method of the determining model parameters with the field experiment data is proposed. The root-cap growth equilibrium coefficient, the shoot-leaf growth equilibrium coefficient and the grain-shoot growth equilibrium coefficient is obtained by the nonlinear program according to the measured dry matter of the winter wheat root, shoot, leaf and grain in 2008 in the irrigation experiment station of Tianjin Agricultural University and the objective function of the minimum absolute error sum on the simulated and measured dry weight. And they are verified by the winter wheat measured data in 2009. The results show that the root-cap growth equilibrium coefficient is most affected by environmental factors, the second is the shoot-leaf growth equilibrium coefficient, the grain-shoot growth equilibrium coefficient is least affected by environment factors. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
