采用大田小区试验,对比研究了不同用量包膜肥与普通肥对早熟油菜籽粒产量和油分产量的影响。结果表明:包膜肥处理的籽粒产量均高于相同用量的普通肥处理,包膜肥处理中B2(包膜肥用量为1 500 kg/hm~2)产量最高,为2 066.9 kg/hm~2, 普通肥处理中A2(普通肥用量为1 500 kg/hm~2)产量最高,为1 839.4 kg/hm~2, B2较A2处理的产量提高12.37%;油分产量变化规律与籽粒产量一致,处理B2最高,为874.5 kg/hm~2, 比处理A2(油分产量为792.8 kg/hm~2)提高10.30%,且包膜肥对油分产量的提高效率随着包膜肥用量的增加而降低。株高、分枝数、单株有效角果与产量呈极显著或显著正相关,对产量贡献最大;包膜肥处理产量的...

A field experiment was studied with the comparative of coated fertilizer and ordinary fertilizer on grain yield an d oil production of precocious rapeseed in different dosage (D), and the correlation of grain yield and agronomic traits was ana-lyzed. The results showed that the grain yield with the same dosage in coated fertilizer treatments was higher than that in ordina-ry fertilizer treatments. B2 ( D: 1 500 kg/hm2 ) , the yield of which was 2 066. 9 kg/hm2 , had the most productive produc-tion among the coated fertilizer treatments. And the yield of B2 increased by 12. 37% than that of A2 ...
