JB-2型精量点播耧播种配合培土铲中耕对旱坪地保水固土及玉米产量的影响
Effect of sowing seeds with precision sowing drill (JB-2) combining intertilling with a ridged sweep on water & soil conservation and corn yield of dry land
摘要
Abstract
[Objective]The paper explored the effect of sowing seeds with precision sowing drill (JB-2) combining interfiling with a ridged sweep on water & soil conservation and corn yield of dry land,so as to provide basis for mechanical planting of other crops.[Methods]In this research,corn seeds were sowed with precision sowing drill (JB-2) while intertillage with a ridged sweep was carried out at the same time.Then length and weight of corn root and stalk,corn yield and dry yield were determined respectively,and the results were compared with traditional tillage.[Results]Field test showed that compared with traditional tillage,the combination of precision sowing drill (JB-2) and ridged sweep resulted in increases of average length of aerial roots per plant (342.94 cm more than the CK),dry weight of roots per plant (13.21 g,i.e.33.50％ more than the CK),yield of per plant (0.244kg,i.e.7.31％ more than the CK),yield of hm2 ' land (444.15kg,i.e.13.26％ more than the CK) and total biological dry weight per hm2 ' land (631.5kg,i.e.8.59％).[Conclusion]S owing seeds with precision sowing drill (JB-2) combining intertilling with a ridged sweep could obviously raise the height of ridges,increase soil moisture,promote root development,enhance soil fixation ability of the plant and improve the yield of land per hm2.关键词
