生物型化肥增效抗盐碱剂在燕麦上的应用

Application of Biological Fertilizer and Synergism Fertilizer-Salt Resistant Agent in Avena sativa L

[目的]为了改善土壤理化性状,增加燕麦产量,降低化肥对环境污染。[方法]以"白燕一号"燕麦品种为试材,采取小区对比方法,研究了化肥增效抗盐碱剂对燕麦生育及产量的影响。[结果]施入抗盐碱剂37.5、75.0、112.5、150.0 kg/hm2处理单产分别为4 222.5、4 356.0、4 465.5、4 536.0 kg/hm2,比对照分别增加了4.0%、7.3%、10.0%、11.7%。在成熟期,这4个处理耕层土壤含盐量分别为0.145 9%、0.144 6%、0.137 6%、0.098 2%,分别比对照降低了0.020、0.021、0.028、0.068个百分点;pH分别为8.27、8.25、8.15、8.12,分别比对照降低了0.20、0.22、0.32、0.35。[结论]抗盐碱剂可降低耕层土壤盐碱危害,增加燕麦产量。

[ Objective ] The research aimed to improve the soil physical and chemical properties, increase the yield of Avena sativa L, and reduce the environmental pollution of chemical fertilizer. [ Method] Baiyan 1 was taken as the material. Plot comparison method was adopted to study the effects of salt resistant agent on the growth and the yield of Arena sativa L. [ Result ] The yields of the treatment of 37.5, 75.0, 112.5 and 150.0 kg/hm2 salt resistant agent were 4 222.5,4 356.0, 4 465.5 and 4 536.0 kg/hm2 respectively, and increased 4.0% ,7.3% , 10.0% and 11.7% compared with CK. In the maturation period, the salt contents in plough layer of the four treatments were 0. 145 9% , 0. 144 6% ,0. 137 6% and 0. 098 2% respectively, and reduced 0.020% ,0.021% ,0.028% and 0. 068% compared with CK. pH was 8.27, 8.25,8.15 and 8.12 respectively, and reduced 0. 20,0. 22,0. 32,0. 35 compared with CK. [ Conclusion] Salt resistant agent could reduce the damage of salt and alkali in the plough layer and increase the yield of Avena sativa L.
