摘要
为进一步研究旱地小麦覆膜沟穴播栽培技术在不同生态区域的增产效果，在前两年试验的基础上又进行了多点试验研究及生产示范。结果表明，覆膜沟穴播较覆膜穴播平均增产１６．７８％，较露地条播平均增产４９．９５％，且有明显的集雨保水、抗旱增产的作用。
In order to further testify the yieldincreasing effect of the technique of dryland wheat cultivation of film mulching and hole seeding in furrows in different places, multispot experiment and demonstration were conducted on the basis of previous twoyear test. The results indicate that the yield of wheat by film mulching and hole seeding in furrows is 16.78% higher than that by film mulching and hole seeding in average, while it is 49.95% higher than that by stripe seeding in rows without mulching. So it has remarkable function in water collection, drought resistance and yield increasing.
