| 中文摘要: |
| 以“白燕一号”燕麦品种为试材,采取小区对比与多点调查的方法,研究了播期、播量、施肥以及耕层土壤盐碱含量对燕麦生育及产量的影响。结果表明:(1)随着播期的推迟,各处理燕麦从播种到出苗的天数以及生育期天数逐渐缩短,处理B3单产260.4 kg/667m2,比B1、B2、B4、B5处理分别增产了15.5%、6.9%、4.6%、10.0%。(2)播量以处理C3的8.0 kg/667m2为宜,其单产372.0 kg/667m2,比C1、C2、C4、C5处理分别增产了9.3%、5.0%、5.4%、16.4%。(3)在施肥量相同的前提下,氮磷全部作基肥,可获得产量250 kg/667m2;若以氮肥的40%作蘖肥施入可使燕麦略有增产;增施抗盐碱剂5.0~10.0 kg/667m2,可使燕麦增产12.5%~17.1%。(4)燕麦遭受盐碱危害,因生长发育受到抑制而减产,其株高、千粒重明显降低,单位面积收获穗数、铃数、粒数明显减少。 |

| With oat variety Baiyan -1 as material ，using plot contrast test and multi district investigation method,
studies were conducted on the effect of the sowing time，sowing rate, fertilizer and soil salt content on growth and yield of oat. The results showed that:(1) With the delayed sowing date，the number of days from sowing to emergence and the days of growth period reduced gradually in each treatment，the yield in treatment B3 got 260. 4 kg/667m2，increased by 15.5%，6.9%，4.6% and 10.0% compared with those in treatments B1, B2, B4 and B5. (2) The seeding rate of 8.0 kg/ 667m2 in the treatment C3 was appropriate， in which the yield got 372. 0 kg/667m2，increased by 9. 3%, 5.0%，5.4% and 16.4% compared with those in treatments C1, C2, C4 and C5. (3) On the premise that the total fertilization amount remained unchanged, the yield got 250 kg/ 667m2 if both nitrogen and phosphorus were used as base-ferilizer, while the yield increased slightly if 40% nitrogen was applied for tillering; Adding 5. 0~10.0 kg/ 667m2saline alkali resistant agent increased the oat yield by 12.5%~17.1%. (4) As oat suffered saline alkaline harm，the yield reduced because the growth and development were inhibited, the plant height and 1000-grain weight decreased sig-nificantly，and panicles harvested per unit area，boll number and grain number decreased significantly. |
