摘要
研究不同施氮量对莴苣产量和经济效益的影响,结果表明:在本试验条件下,每667m^2施N 20kg效果最优,莴苣产量为3079.21kg,净收益1540.87元,产投比为17.7。
Effect of different amount of nitrogen application on the yield and economic benefit of lettuce were studied.The results showed that under the experimental conditions,20 kg/667 m 2(300 kg/hm 2)N application had the best effect,the yield of lettuce was 3079.21 kg and the net income was 1540.87 RMB Yuan,and the ratio of output to input was 17.7.
