) :22-23 .30-3% and 28.0%. The study also found that in semi arid areas by the fall or the top [21 Shang Wu Xun, Yang Qi Feng, Liu was.

Agricultural Research, 2007 (25) (Supplement) :194-196 * to achieve high yield and high yield, is the area of maize increased by leaps and bounds to achieve the best yield [31 Yang, Qi Feng, Xin Sun and more, Xiong Chunrong, so the whole film corn Double furrow sowing cultivation technology fJ] - China's way. Agricultural extension, 2007,23 (8) :20-21 * [4] Liu before, Yang Qi Feng, Duan limitless full, and so on. Gansu development of the whole film double furrow sowing dry technology 4 Summary Covering Film yield increased 4.1 full-film double furrow sowing technology is extremely significantly higher than the half-film double furrow sowing technology, semi-membrane double furrow sowing was significantly higher than semimembranosus Tile Dibble; time increase range of different film coating treatment was the highest in autumn, followed by the top film Ling, the minimum film before sowing. Multiple comparisons revealed that the whole film in autumn double ridge furrow treatment yields the highest spring, top the whole film Ling double ridge furrow treatment, followed by spring and autumn, spring, full-film double ridge and furrow roof Ling entire membrane and double ridge Spring Sowing significantly higher than the double-furrow before sowing broadcast the whole film, all three yield was significantly higher than that covered different periods of double-furrow sowing half of film production in each treatment; half of the film on the double furrow sowing treatment was significantly higher than that of semi-production film Tile each treatment, the difference was significant, but the increase rate was lower than that of the whole film double furrow sowing treatment; control (ck) Bunch semimembranosus tile lowest yield. 4.2 Area of different dry film double furrow sowing the whole technology showed significant yield increase: ARID AREAS> Semi> in semi arid areas, show that the more drought, more intense corn to water-dependent , reflecting on the water the more sensitive. All three fall dryland spring furrow membrane double ridge sowing of corn than the control tile first half of film Bunch (below) increase rate was 48.1%, 39.6% and 34.3%, all the top film double Ling Ridge Spring Sowing of maize yield than the control rate was 40.6%, 35.0% and 31.7%,tory burch outlet, the whole film double furrow before sowing maize sowing rates were higher than CK 35. O%, 30.3% and 28.0%. 4.3 The whole film in different dryland maize double furrow sowing increased yield is evident in the semi-humid arid> Semi> ARID AREAS. All three major modes fall dry area [J].
