4种玉米单粒播种机播种效果的研究

Research on Sowing Effect of 4 Maize Simple Grain Sowers

通过大田试验,研究4种玉米单粒播种机的播种效果。使用2种指夹式玉米单粒播种机和2种勺轮式玉米单粒播种机播种玉米,考察播种质量、玉米生物学性状及产量。结果表明:河北农哈哈机械集团有限公司的2BYJF-3指夹式玉米播种机所播种玉米的出苗率最高,均匀度和整齐度最好,且重播、漏播率小于其他3种玉米单粒播种机;4种玉米单粒播种机对玉米的生物学表现性状影响不大,2BYJF-3指夹式玉米播种机所播种玉米的田间效果最好。

By field experiment,sowing effect of4maize simple grain sowers was studied.Using2kinds of finger-clip-pattern sowers and2kinds of spoon wheel type maize simple grain sowers to sow maize,the sowing quality,biological character and yield of maize was investigated.The results showed that:2BYJF-3finger-clip-pattern sower,which belongs to Hebei Nonghaha Machinery Group Co.,Ltd,has the highest maize emergence rate and the best uniformity and evenness,and the rate of reseeding and miss-seeding are all less than the other3maize simple grain sowers;The influence of4maize simple grain sowers on maize biological character is little,and maize sowed by2BYJE-3finger-clip-pattern is highly-effective in field.
