Abstract: |
The effect of using and combing different chemical control agents on soil moisture and growth, yield and quality of maize was investigated.The results showed that application of 75 kg/hm2 water retaining agent, spraying antitranspirant (Fulvic acid, FA) and broadcasting soil conditioner significantly enhanced the stability of soil water content and the growth and quality parameters of maize.Compared with maize in control treatment, seed yield, crude protein, leaf area in jointing stage and total dry matter of maize were increased by 17.62%, 9.94%, 41.95% and 37.38%, respectively. |
