彭阳县冬小麦全膜覆盖微垄穴播技术效益研究

Experimental Research on the Benefit of Winter Wheat All Membrane Mulching Micro-ridge Hole Seeding Technology in Pengyang County

对彭阳县冬小麦进行全膜覆盖微垄穴播技术研究,结果表明:冬小麦全膜覆盖微垄穴播技术较露地条播(CK)生育期0~25 cm土壤平均地温提高0.47~3.40℃,开花期和成熟期0~100 cm土壤含水量提高1.97%~3.03%,返青期和抽穗期土壤储水量增加37.0~44.8 mm,水分生产率提高0.40 kg/mm;株高、穗长、穗粒数、穗粒重和千粒重分别比CK增加34.0 cm、1.4cm、7.8粒、0.58 g、8.5 g;缩短生育期3 d,增产2 953.9 kg/hm^2,增幅82.75%;纯收入增加9 764.52元/hm^2,产投比2.01。

Winter wheat all membrane mulching micro-ridge hole seeding technique was studied in this paper. Results showed that soil average temperature was 0.47 ℃ to 3.40 ℃ higher than that of CK at 0 to 25 cm during the growth period, soil water content was 1.97% to 3.03% higher at 0 to 100 cm during the blossom and mature period, soil reserve was 37.0 to 44.8 mm during green period and heading period and water production rate was 0.40 kg/mm. Plant height, panicle length, panicle number, panicle weight and a thousand panicle weight were increased by 34.0 cm, 1.4 cm, 7.8 grains, 0.58 g and 8.5 g respectively. Growth period decreased by 3 days and output increased by 2 953.9 kg/hm^2. Net income increased by 9 764.52 yuan/hm^2, and output versus input rate was 2.01.
