本试验对重盐碱地 (土壤含盐量 0 96 %～ 1 2 5 % )的抗盐小麦进行覆膜试验 ,结果表明 ,重盐碱地覆膜提高了土壤温度 ,防止土壤水分蒸发 ,更重要的是抑制土壤返盐 ,改善土壤物理性状 ,有效地促进小麦生长发育 ,促进各器官建成 ,提高 6 6 6 7m2 穗数、穗粒数、千粒重 ,防止早衰 ,极大地提高重盐碱地小麦产量。
In this study, salt-tolerant wheat in saline-alkali land (soil salinity 0 96% ~ 125%) was mulched with plastic film. The results showed that plastic film with heavy saline-alkali soil increased soil temperature and prevented soil water evaporation, and more importantly, Soil salt return, soil physical properties improved, effectively promote the growth and development of wheat, and promote the completion of various organs, increase 6 6 6 7m2 spikes, grains per spike, 1000 grain weight, prevent premature aging, and greatly improve the yield of heavy saline alkaline wheat.
