Researh On Water Consumption For Crop Under Wide Ditch Irrigation

The article bases on the field experiment,and the combination of theoretical research and mathematical analysis of research methods,in-depth study of the winter wheat and summer maize growth period of crop physiological and ecological characteristics,grouting process,crop change rule and crop water requirement rule and the relationship between each other.Under different planting patterns,the stress of water both have the effect on the reproductive process;the change trend of leaf area for winter wheat are similar from 2012 to 2014 year;Under different planting patterns,the grain weight of winter wheat are lengthened with the increase of moisture control limit from 2012 to 2014 year;This suggests that too high moisture treatment had no obvious promoting effect on the grain filling speed,the proper water treatment(L-70)can effectively promote the grain growth,achieve the benefit of water saving and high yield;Under different planting patterns,the output and its components factor of winter wheat and summer maize are lengthened with the increase of irrigation water from2012 to 2014 year;Under different planting patterns,the correlation between panicle traits and yield of winter wheat and summer maize are high from 2012 to 2014 year,make the change of the size of the corresponding correlation coefficient.This shows that different ways of planting will affect the relationship between crop panicle traits and yield.Under different planting patterns,the change trend of water consumption in the reproductive period for winter wheat and summer corn are similar from 2012 to 2014 year.When the same water treatment,compared with the conventional planting,the water consumption in the whole stages in the wide ridge planting are reduced for winter wheat and summer maize.Under different planting patterns,the relationship between the yield and water consumption meet the quadratic parabola form for winter wheat and summer maize from2012 to 2014 year,showing a rapid growth-slow growth-negative growth trend.This suggests that the wide ridge planting have good effect on achieving the goal of water-saving high-yield for winter wheat and summer corn.
