生物基磺酸盐固沙性能及其对种子萌发和出苗的影响
Sand-fixing properties of bio-based sulfonates and the effects on seed germination and emergence
摘要
Abstract
By designing different dosage of bio based sulfonate,the consolidation layer,surface temperature and sur-face soil moisture after spraying were measured,and their effects on plant seed germination and emergence were ob-served.The thickness and hardness of the consolidation layer increased with the increasing of the amount of bio based sul-fonate.The thickness of the consolidation layer was 5.56-15.13 mm,with an average thickness of 10.42 mm.The hardness of the consolidation layer was 0.24-1.69 kg·cm-2,with an average hardness of 0.79 kg·cm-2;The use of bio based sulfonate significantly increased the surface temperature of sandy soil;The soil water holding capacity was bet-ter when the dosage was 50-100 g·m-2.Sulfonate had a certain inhibitory effect on seed germination and emergence,and the emergence rate decreased significantly when the dosage was greater than 100 g·m-2.The suitable dosage of bio based sulfonate in aeolian sandy soil treatment should be 50-100 g·m-2,and its inhibition on seed germination can be reduced by increasing the dilution ratio.关键词
