摘要:

为探究菜用大豆浙鲜9号的氮(N)、磷(P2O5)、钾(K2O)最佳施用量,本研究开展了单因素肥效试验。结果表明,当施N量为300 kg·hm-2时,豆荚产量和总产量最高,为12 400和20 950 kg·hm-2;施N量为150~375 kg·hm-2时,豆荚产量随着施N量的增加而增加;当施P2O5量为0时,豆荚产量最高,为12 367 kg·hm-2,但当施P2O5量为0~112.5 kg·hm-2时,豆荚产量随着施P2O5量的增加而降低;当施K2O量为75 kg·hm-2时,豆荚产量最高,为12 500 kg·hm-2,当施K2O量为75~375 kg·hm-2时,豆荚产量随施K2O量的增加而减少。以豆荚产量为主要考量指标,本研究认为N 300 kg·hm-2+P2O5 0 kg·hm-2+K2O 75 kg·hm-2为菜用大豆浙鲜9号的最佳施肥量。

Abstract:

In order to determine the optimal application amount of N,P2O5,and K2O for Glycine max (Linn.) Merr. Zhexian 9,a single factor fertilizer efficiency experiment was conducted. The results showed that when the N application amount was 300 kg·hm-2,the pod yield and total yield were the highest,at 12 400 and 20 950 kg·hm-2,respectively. When the N application amount was 150-375 kg·hm-2,the pod yield showed an increasing trend with the increase of N application amount. When the application amount of P2O5 was 0,the maximum yield of pods was 12 367 kg·hm-2. However,when the application amount of P2O5 was 0-112.5 kg·hm-2,pod yield decreased with increasing P2O5 application amount. When the application amount of K2O was 75 kg·hm-2,the maximum yield of pods was 12 500 kg·hm-2. When the application amount of K2O was 75-375 kg·hm-2,the pod yield showed a decreasing trend with increasing K2O application amount. Considering pod yield as the primary indicator,this study indicates that the optimal fertilizer application amount for Glycine max (Linn.) Merr. Zhexian 9 are N 300 kg·hm-2+P2O5 0 kg·hm-2+K2O 75 kg·hm-2.
