| 摘 要： | 以胡萝卜肉质直根产量为主要指标,采用3414配方施肥设计进行试验,确定柴达木地区胡萝卜高产的最佳施肥措施。结果表明:在柴达木地区随着氮肥施肥量的增加,胡萝卜的产量逐渐增加,但当施肥量增加到一定程度时,胡萝卜的产量达到最大,之后随着氮肥的增加开始降低;磷、钾肥也表现出此规律,对胡萝卜产量影响依次为氮磷钾;磷钾配合对胡萝卜产量的作用最大。最佳经济效益时667m2的胡萝卜产量达到5 125.2kg,此时的氮肥、磷肥和钾肥最优组合为尿素55.2kg,过磷酸钙171.7kg,氯化钾16.1kg。

| Abstract: | Taking fleshy taproot yield of carrot as the main index,the best high-yield fertilizer measures in Qaidam area were determined by the methods of 3414 formulated fertilization.The results showed that the carrots yield was increased along with the increased amount of nitrogen fertilizer,but the carrots yield got to the maximum when fertilization increased to a certain extent,and then it began lower along with the increase of nitrogen fertilizer,the same as the phosphatic fertilizer and the potassic fertilizer,the influence order on the carrots yield was nitrogen>phosphonium>potassium;it had the largest effect on carrort yield when we combined phosphonium with potassium.Optimal economic benefits of carrort yield reached 5 125.2 kg/667m2,at that time,the optimal combination of the nitrogen fertilizer,the phosphatic fertilizer and the potassic fertilizer were urea 55.2 kg/667m2,calcium surphsphate 171.7 kg/667m2,potassium chloride 16.1 kg/667m2. |
