Study on the Application Effect of Drought-Resistant and Water-Retaining Agent on Maize in Western Liaoning Province
Drought and low rainfall,poor soil water retention capacity and low water use efficiency have been the key factors restricting the yield increase of maize in western Liaoning.The effects of mixed application of drought-resistant water-retaining agent and fertilizer and conventional fertilization on maize growth character and yield were studied by comparative experiment.The test results showed that the growth characteristics of maize with drought-resistant water-retaining agent was better than that with conventional fertilization,with plant height increased by 6.0~16.4 cm,stem diameter increased by 0.28~1.30 cm,grain number per spike increased by 42~54,grain mass per 100 increased by 1.05~1.70 g,and yield increased by 87.80~121.55 kg/667 m2,and yield increased from 10.20%to 17.29%.
