Maize is the most important crop for food and widely used for industrial materials,leading to its increasing demand all over the world.Precision planting is the effective method to increase maize yield.To meet the agronomic requirement of precision planting,different kinds of precision maize planters were developed.However,because of the difference of geographical environment,cropping system,farm scale and economic status among different countries,types of maize planters are various and the technologies involved are at different levels.This paper summarizes the precision maize planters currently available in the world and classifies them into four types:precision planters for tilled-land,minimum/no tilled-land,hilly&small land,and cold&arid land.Detailed characteristics have been provided for some typical precision planters and comparisons were made as to their suitability under particular working conditions.High-efficiency and high-accuracy are the main features of precision planters for tilled-land,while the ability to clean residue from seed rows and prevent planters to be blocked are the important function of precision planters for minimum/no tilled-land.To fit for hilly&small land,planters should be light-weighted and small-sized,and to warm up soil and keep moisture,planters for cold&arid land should be equipped with plastic-film mulching mechanism.Finally,developing trend of precision planting technology was analyzed and suggestions,including policy support and technical improvement,were made for developing countries to make suitable precision maize planters according to the local geographical conditions and cropping systems. 展开更多

Visualizing social networks,especially an overview emphasizing their structure,i.e.,communities and their interconnections,is known to be a challenging problem.In this paper,we present a set of design rationales to build such overview visualizations of social networks and our solution called Jasper.We evaluate its performances against two of the most wide-spread visualization techniques(matrix and node-link diagram)in a human–computer controlled experiment based on community-related tasks.While none of the techniques emerge as the overwhelming winner,Jasper appears to be one of the best methods for each task;a fact sustained by the marks given by the users.Overall,Jasper can be seen as an all-encompassing solution for quickly producing legible and compact overviews of large social networks on a single modern computer. 展开更多
