Field experiment study into influence of spring drought on maize yield

This paper studies the influence of spring drought on maize yield based on the combination tests of soil water stress test and field test of seeding trials.Results show that during the corn planting and emerging periods,the relationship between soil water content and corn yield follows a quadratic function.Spring water stress of soil on maize yield is very obvious.In field water capacity,soil humidity declied by 1 percentage points each,maize yield will be reduced by about 7%;soil effective water reduction for every 10 mm,per unit area yield will drop about 14%.The article also identified maize drought index of soil moisture.The influence of soil moisture decrease on the corn yield was quantitatively studied.The indicator and mode of soil moisture influence on maise yield can be used for developing the assessment and prediction of maize spring drought,and can also be used to determine drought-resistant irrigation content.
