| 摘 要： | 本文针对四川丘陵旱区小麦受水分影响，产量不稳不高的问题，通过不同耕作方式，初步研究了花后小麦干物质积累及相关生理指标。明确了2m带距问作是丘陵旱区小麦的高产栽培模式，其中，间作高于净作，平作高于垄作；分蘖成穗率和最大灌浆速度是丘陵区高产的关键因子。 |

| Abstract: | Yield of wheat was not steady and high in hill drylands in the central areas of Sichuan due to water deficit. The dry matter accumulation and physiological index of dry land wheat after blooming was studied through different farming methods. The results showed the planting method of 2 m stripe width was the highest yield model of wheat in hill dry-lands, the yield of interplanting was higher than that of all-planting,and the wheat yield of planar method was higher than that of ridgy method . In order to achieve high-yield of wheat, the increase of dry matter accumulation and filling rate of wheat after blooming were key factors. |
| Keywords: | farming methods wheat drought dry matter accumulation physiological index |
