包膜互混肥对油菜养分吸收和产量的影响

Effects of Coated Mutual Mix Fertilizer on Nutrients Absorption and Yield of Oilseed Rape

为了探明包膜肥对油菜产量和养分吸收的影响,采用田间小区试验,研究包膜互混肥对‘湘杂油1613’氮磷钾养分吸收和籽粒产量的影响。结果表明:施肥量相同的条件下,包膜互混肥能够显著提高油菜籽粒产量,产量达到2646.1kg/hm2,增产幅度为26.9%。包膜互混肥能够有效提高有效角果数和每角果粒数,千粒重也有小幅提高。包膜互混肥处理氮磷钾积累量相对较高,且氮磷钾积累量与产量的相关性达到显著水平。

For the effects of coated mutual mix fertilizer on nutrients absorption and yield of oilseed rape field experiments were conducted to investigate effects of coated mutual mix fertilizer on N, P, K （nitrogen, phosphorus, potassium） uptake and seeds yield of ＇Xiangzayoul613＇. The results showed that, coated mutual mix fertilizer could improve yield of oilseed significantly under the same rate of fertilizer, the yield had reached 2696 kg/hm2, increase rate was 26.9%. Coated mutual mix fertilizer could improve effective pod and seeds per pod significantly also, and 1000-seed weight had a little increase, yet. Coated mutual mix fertilizer treatments had higher N, P, K accumulation amount, tendency of N, P, K accumulation amount was similar with seeds yield, and there was significant relationship between yield and N, P, K accumulation amount.
