在渭北山区种植冬小麦采用膜侧沟播、覆膜沟穴播、平膜穴播、露地条播的试验表明，４ 种方式的土壤含水量（０～３０ ｃｍ ）大小依次为膜侧沟播、覆膜沟穴播、平膜穴播、露地条播；植株株高、穗长、小穗数由大到小顺序为覆膜沟穴播、平膜穴播、膜侧沟播、露地条播；产量水平高低的次序为覆膜沟穴播、膜侧沟播、平膜穴播、露地条播。地膜小麦不同播种方式在干旱少雨的山区均有良好的增温保墒效应，小麦生育期缩短，增产效果显著
The results showed that the soil water content (0 ~ 30 cm) of four ways was followed by film sowing and film mulching in the order of film sowing, film mulching sowing, film mulching sowing and field sowing in the Weibei mountainous area. The order of planting height, spike length and spikelet number were mulching and sowing, mulching and film mulching, open-sowing and mulching; the order of yield level was Membrane ditch sowing, ditch sowing on film side, flat film sowing and opencasting. The different planting methods of mulching wheat showed good warming and moisturizing effect in the arid and dry mountainous areas, shortened the growth period of wheat and increased the yield significantly
