大田旱作条件下，研究了氮磷配肥对胡麻产量、品质和农艺性状的影响。结果表明，氮磷配施均能增加胡麻产量，当氮肥用量一定（N 30～60 kg?hm －2）时，增施磷肥（P2O522．5～90 kg?hm －2）能使胡麻籽粒产量较对照增加50．00％～84．23％；当磷肥用量一定（P2O530～120 kg?hm －2）时，增施氮肥同样促进胡麻产量，但低磷高氮肥和高磷高氮肥反而不利于胡麻产量的增加；氮肥效果比磷肥明显，其中以 N2 P3处理（N 60 kg?hm －2，P2O567．5 kg?hm －2）产量最大，达到1719．44 kg?hm －2。增施氮肥能够增加胡麻的株高、工艺长度、千粒重、分茎数、主茎分枝数和单株有效果枝数，高磷肥反而不利于胡麻农艺性状的改善。氮磷配施使胡麻棕榈酸含量较对照增加0～5．62％，油酸的含量较对照增加 0 ～ 4．06％，施用氮肥可增加胡麻的亚油酸和亚麻酸含量，而高磷肥反而降低了亚油酸和亚麻酸含量。

In dry conditions ,influences of nitrogen and phosphorus fertilizers on yield ,quality and agronomic traits of benne were investigated .The results showed that nitrogen and phosphorus fertilizers could increase the yield of benne when proper amounts of nitrogen fertilizer (N 30 ~ 60 kg?hm - 2 ) and phosphate fertilizer (P2O5 22 .5 ~ 90 kg?hm - 2 ) were applied ,increasing benne seed yields by 50 .00% ~ 84 .23% .When certain amount of phosphate (P2O5 30 ~ 120 kg?hm - 2 ) was used ,elevated amount of nitrogen also promoted benne yield ,whereas low phosphorus and high nitrogen or high phosphorus and high nitrogen fertilizers displayed adverse effects on benne yield .N fertilizer played a more pre-dominant role in affecting yield than phosphorus fertilizer .In particular ,the N2P3 treatment (N 60 kg?hm - 2 ,P2O567 .5 kg?hm - 2 ) achieved the highest yield ,a maximum of 1 719 .44 kg?hm - 2 .Nitrogen fertilization could increase plant height ,length of benne processing ,1 000 grain weight ,stem number ,number of branches per plant and effective branch number .However ,high phosphorus did not help the improvement of agronomic traits of benne .The effects of combined application of nitrogen and phosphorus fertilizers on the contents of palmitic acid and oleic acid were positive ,resulting in an increase of 0 ~ 5 .62% and 0 ~ 4 .06% ,respectively .Nitrogen fertilizer could increase the content of noleic acid and linolenic acid ,but high phosphorus application exhibited opposite effects .
