六种不同覆膜方式和六个不同品种的对比试验表明： 旱地小麦采用膜侧双行条播增产增收效益最显著， 其地膜用量较全覆膜的节省５０ ％ ， 品种以选用云麦４２ 号和攀９３ － １ 为宜。全覆膜穴播的， 在小麦拔节前， 保湿效果最优， 但不利于吸纳冬春雨雪； 开花至成熟期的土壤含水量明显偏低。其增温效果明显好于其它覆膜方式， 对土壤中钾和磷的吸收利用率最高。６－６７ 公顷膜侧条播旱地小麦， 平均每公顷增产１ １８６－６５ｋｇ， 增产率达５２－３１ ％ 。对解决山区半山区农民的温饱和脱贫致富， 具有十分重要的意义。
Six kinds of different coating methods and six different varieties of comparative tests showed that: Dryland wheat double-sided film double-sided film yield increase and yield the most significant benefit, the film than the whole film to save 50% of the amount of varieties to use Yunmai 42 and Climb 93 - 1 is appropriate. All film-sowed, before the wheat jointing, moisturizing effect is best, but not conducive to absorb the winter and spring rain and snow; flowering to maturity of the soil moisture was significantly lower. Its warming effect is obviously better than other coating ways, and it has the highest absorption and utilization rate of potassium and phosphorus in the soil. 6-67 hectares membrane dryland wheat, an average yield of 1 186-65kg per hectare, yield 52-31%. It is of great significance to solve the problem of becoming rich in food and clothing and getting rid of poverty in the Mid-levels of mountainous areas.
