摘要
进行了小麦固氮菌拌种撒播、沟播和三行分层施肥条播大田试验,结果表明,固氮菌拌种,667m2增产33.5kg,沟播的平均产量比撒播增产13.2%,三行分层施肥条播比沟播的平均产量增产38.5%,比撒播增产56.8%。
The test on wheat nitrogen fixing bacteria seed sowing, furrow planting and three layered fertilizer drill field experiment were conducted,results show that the seed dressing nitrogen fixing bacteria,667m^2 yield were 33.5kg,average yield of furrow sowing increased 13.2% than sowing,the average yield three layered fertilizer drill increased 38.5% than that of furrow sowing,increase 56. 8% than that of broadcast.
