硼肥对旱地胡麻生长及产量的影响

Effect of Boric Fertilizer on the Growth and Yield of Flax in Arid Land

以胡麻为试材,探讨宁夏固原地区微量元素硼不同施用量(1.0、1.5、2.0kg/667m2)对旱地胡麻生长和产量的影响,开展不同用量硼肥对胡麻生长量、农艺性状和种子产量的单因素完全随机区组试验。结果表明:增加硼肥用量可以提高胡麻植株的鲜重、干重及农艺性状指标,但除对有效结果数有明显作用外对其它参数影响均不显著。随施硼量的增加,胡麻种子产量增加明显降低,每667m2施硼肥1.0kg处理产量最高,每667m2施硼肥1.5kg和2.0kg较每667m2施硼肥1.0kg减产10.06%和13.61%。综合分析认为,在基施磷酸二铵的基础上,每667m2施硼肥1.0kg可获得较好的胡麻产量。

Taking flax as test material,the boric fertilizer was applied to arid flax by arranged in a completely randomized factorial design with three levels（1.0kg/667m^2,1.5kg/667m^2 and 2.0kg/667m^2）,the growth amount,agronomic characters and seed yield of flax in areas of Guyuan city,Ningxia province were studied.The results showed that,with the increasing of boric fertilizer dosage could raise fresh weight,dry weight and agronomic characters of flax,it has marked effect on effective number of fruits except other growth and agronomic characters index.With increasing of boric fertilizer dosage,flax seed yield decreased effectively,flax treated with boric 1.0kg/667m^2 had maximum yield,the treatment with boric 1.5kg/667m^2 and 2.0kg/667m^2 had a production cuts which was 10.06% and 13.61% compared with boric1.0kg/667m^2.Comprehensive analysis showed that flax added with boron fertilizer at 1.0kg/667m^2 under normal application of other elements fertilizers such as P produced could get higher yield.
