Dryland Dilute Hole Density Lines Cropping Patterns, And Its Complement Irrigation Technology

Studies on Central Planting in Less Sockets and its Method of Irrigation in Dry and Abstract At present, people pay more attention to the lack of water resources. In agriculture research, it is an important subject that, how to search for a way to use water more effectively, both ensure supplies of water resources for crops and avoid wasting water resources in irrigation. This paper were carried out to study the central planting in less sockets and its irrigation methods. Studies were based on the technology of Carrier Planting in Dry-land. The experiments of Central Planting in less sockets design was one factor, it has three treatments: (l)plant one corn in a socket(CK); (2)plant three corn plants in a socket; (3)plant five corn plants in a socket. The same water was supplied for every socket. The experiment of irrigation was carried in Lab. Subsurface irrigation was used in this experiment. The studies results can be concluded as follows: 1 .Under limited water resources, equal quantity of water was supplied for every socket. The treatment of planting three corn plants in a socket had the highest yield. The yield of planting five corn plants in a socket took second place. And the yield of planting one corn in a socket(CK) was the lowest. 2.Through the experiment in the Lab, we concluded the relationship between the quantity of subsurface irrigation and irrigating time, and the relationship between the spreading distance of irrigating water and irrigating time in different quality and composition of the soil. Based on this mathematics model, people could supply water for the plants more suitably in Dry-land.
