不同类型播种机对大豆农艺性状和产量的影响

Effects of Different Seeders on Agronomic Traits and Yield of Soybean

以齐黄34大豆品种为材料,研究三种播种机(派克、马特马克和嘉祥大豆播种机)在相同行株距播种条件下收获期大豆的单株荚数、单株粒数、百粒重及产量。结果表明:用派克播种机播种,大豆密度最高,虽单株荚数和粒数下降,但因播种均匀度较好,产量最高;马特马克播种机播种,密度最低,但单株荚数和粒数最多,播种均匀度也较好,产量次之;嘉祥大豆播种机播种,密度较高,但均匀度较差,产量最低。

The soybean variety Qihuang 34 was used as the material.The pod number per plant, seed number per plant, 100-seed weight and the yield of soybean harvested by three kinds of sowing machines (APEAK, MaterMacc and Jiaxiang soybean seeders) at the same row spacing and plant spacing were investigated during the harvest period. The results showed that the density of soybean was the highest when planted with the APEAK seeder, although the number of pods and seeds per plant decreased, and the yield was the highest due to better uniformity of sowing. MaterMacc seeder had the lowest density but the most number of pods and seeds per plant,and the better uniformity,so the yield was the second. Although the density of sowing was higher using Jiaxiang soybean seeder, the uniformity was poor,so the yield was the lowest.
