中文摘要:
      摘 要:为筛选出适宜盐碱地燕麦生长、增产增效的改良措施,试验设8个处理分别为对照(A)、腐熟秸秆还田(AF)、750 kg/hm2菌肥(B)、腐熟秸秆还田 750 kg/hm2菌肥(BF)、1500 kg/hm2菌肥(C)、腐熟秸秆还田 1500 kg/hm2菌肥(CF)、2250 kg/hm2菌肥(D)、腐熟秸秆还田 2250 kg/hm2菌肥(DF),并对盐碱地燕麦形态指标、光合特性及产量进行研究。结果表明:腐熟秸秆还田和菌肥均有利于燕麦在盐碱地生长,各时期CF处理燕麦株高、根长、根系活力、Gs、Tr、Pn、Ci和SPAD等指标较其他处理表现最好;其中CF处理的籽粒产量、鲜草产量和干草产量最高,分别达3530 kg/hm2、30910 kg/hm2和6521 kg/hm2,较其他处理分别高出31.23%~129.22%、10.47%~102.69% 和8.73%~109.10%。若不使用腐熟秸秆的情况下,菌肥最佳施入量为750 kg/hm2,综合评价,1500 kg/hm2菌肥结合腐熟秸秆还田是该地区盐碱地改良的最佳措施。
英文摘要:
      To select the appropriate improvement measure for the growth of oats and the increase of yield and efficiency on saline-alkali land, the authors studied the morphology, photosynthetic characteristics and yield of oats in saline alkali soil, which were affected by eight treatments, including traditional management (A), straw decayed returned (AF), 750 kg/hm2 bacterial manure (B), straw decayed returned and 750 kg/hm2 bacterial manure (BF), 1500 kg/hm2 bacterial manure (C), straw decayed returned and 1500 kg/hm2 bacterial manure (CF), 2250 kg/hm2 bacterial manure (D) and straw decayed returned and 2250 kg/hm2 bacterial manure (DF). The results showed that the bacterial manure and straw decayed returned were all beneficial to the growth of oat in saline alkali land. Treatment CF was the best one, which had the highest plant height, root length, root vigor,Gs ,Tr ,Pn ,Ci andSPAD compared with those of others. What is more, treatment CF had the highest grain yield, fresh yield and hay yield, which was 3530, 30910 and 6521 kg/hm2, respectively, and 31.23%-129.22%, 10.47%-102.69% and 8.73%-109.10% higher than those of other treatments. The best application amount of bacterial manure was 750 kg/hm2 without rotten straw. To sum up, straw decayed returned and 1500 kg/hm2 bacterial manure is the best way to improve saline-alkali land.
