Study on the Application of Water-retaining Agent in Sugarcane Field Cultivation
The super absorbent polymer could improve the physical and chemical properties of the soil and make it have good biological properties,so as to meet the requirements of water,oxygen,heat,nutrients and other conditions at different growth stages of sugarcane,and could well coordinate these growth conditions.The test had carried out in Huahai,and divided it into 75 kg/hm2,105 kg/hm2 different application rates and treatment with and without film covering.The results showed that the yield of sugarcane per hectare could be increased by applying super absorbent polymer under the same condition of film covering cultivation.Compared with the control treatment,the yield of sugarcane was increased 4.70%,6.17%and 14.08%by applying super absorbent polymer at the level of 75,105 kg/hm2 without covering film,and 105 kg/hm2 with covering film respectively.According to comprehensive analysis,the highest yield was obtained by applying super absorbent polymer at 105 kg/hm2 and covering film cultivation.
