Effects of Different Cultivation Technique on Soil Moisture, Unit Capacity Weight and Yield of Soybean
摘要
Abstract
Drought caused by limited and unevenly distributed rainfall has became a severe environmental factor affecting soybean production in Heilongjiang province in recent years. In the current research, different cultivation technique combinations, including "three ridge"(TR,CK) ,film mulching between ridge and furrow deep loose(FMBRFDL) ,solid-seeding flat-planting with deep loosening and chemical control(SSFPDLCC),solid-seeding on big ridge and furrow deep loose(SSBRFDL),solid-seeding on small ridge(SSSR) .solid-seeding flat-planting(SSFP)and "three ridge" with chemical control(TRCC) were performed in 2010 with semi-dwarf cultivar Suinong 22 as material. Soil moisture and bulk density at different growth stage,yield components at harvest,as well as the calculated water use efficiency were determined. At seedling stage,the 0-10 cm soil moisture of FMBRFDL.SSBRFDL.SSFP,SSFPDLCC increased by 10.57% ,3.17% ,4.41% and 2. 62% .respectively;at branching stage,the 0-50 cm soil moisture of FMBRFDL,TRCC,SSBRFDL and SSFP increased by 8. 13% ,3. 06% ,4. 73% and 1.48% .respectively,compared with control. FMBRFDL and SSBRFDL had lower soil bulk density,higher water use efficiency, and significantly increased soybean yield by 0. 83% and 11.96%. Results suggest that the cultivation techniques of SSBRFDL and SSFP have better application prospects in arid and semi-arid area of Heilongjiang province.关键词
