摘  要:
以海滨锦葵为材料,在沿海滩涂上研究了不同施氮水平(0、75、1502、25 kg/hm2)与施磷水平(0、30、60、90 kg/hm2)对海滨锦葵生长及品质的影响。结果表明:施用氮磷肥对海滨锦葵生长、籽粒产量及品质影响显著。N2(75 kg/hm2)-N4(225 kg/hm2)、P2(30 kg/hm2)-P4(90 kg/hm2)水平的氮磷肥可促进海滨锦葵生长,株高最大增幅为48.6%;在150 kg/hm2(N3)的施氮量3、0 kg/hm2(P2)的施磷量下,海滨锦葵籽粒产量最高,达到148 kg/hm2,比不施肥处理(N1P1)增加了53.6%,蛋白含量达到28.2%,比不施肥处理(N1P1)增加了25.5%。影响海滨锦葵籽粒产量及品质的主要因素是氮肥,磷肥次之。150 kg/hm2的施氮量3、0 kg/hm2的施磷量最有利于海滨锦葵籽粒产量的增加和品质的积累。

摘  要:
A field experiment was carried out to study the effects of nitrogen fertilizer(0,75,150,225 kg/ha) and phosphatic fertilizer(0,30,60,90 kg/ha) on the growth and quality of Kosteletzkya virginica L..The results showed that the effects of N and P fertilizers on the growth,grain yield and quality of Kosteletzkya virginica L.were marked and could promote the growth,the maximum plant height could be increased to 48.6%.The grain yield was the highest and reached 148 kg/ha,increased by 53.6%;the protein content reached 28.2%,increased by 25.5% compared with N1P1 treatment of 150 kg/ha nitrogen fertilizer,30 kg/ha P fertilizer.Through the analysis of alternant effects,the factors for the grain yield and quality of Kosteletzkya virginica L.was N fertilizer,then followed by P.The best combination was N3P2,150 kg/ha Nfertilizer,30 kg/ha P fertilizer.
