Effect analysis on water control irrigation technology of rice in Heilongjiang reclamation area;

This paper introduced the technology of rice control irrigation and analysed water saving and increasing production mechanism.

Based on the situation that our nation is seriously lack of water, and for the object of saving water, water saving irrigation system is being more and more used, and irrigation control technology is developing rapidly.

Considering the current status of irrigation and drainage systems in China,the W.

Elementary reflection is that the effect of the well water irrigation and reclaimed water irrigation to the heavy metals accumulation in plant is lest.

Based on the experiment studies,the study on water and solute transport in sandy soil under reclaimed water irrigation was made,The result can give some reference for the effect on soil solute transport and soil environment under micro-contaminated water irrigation.
