不同施肥对南板蓝养分含量及产量的影响

通过田间试验和室内分析,研究了不同施肥对南板蓝养分含量及产量的影响。结果表明,氮肥、磷肥对南板蓝的氮、磷、钾素的含量及氮、磷、钾素总量和产量均有显著影响,钾肥仅对南板蓝的钾素含量及氮、钾素总量和产量有显著影响,有机肥仅对南板蓝的氮、磷素含量及氮素总量和产量有显著影响。通过多重比较确定了氮、磷、钾及有机肥的合理施肥量分别是48g/株的尿素、14~21g/株的普钙、3g/株的硫酸钾及80g/株的有机肥。

Effect of different fertilizations on the nutrition contents and the outputs for Baphicanthus Cusia Bremek

Using the field experiment and chemical analysis, this essay studied the effect of different fertilization lever on the nutrition contents and the outputs for Baphicanthus Cusia Bremek. The results showed that nitrogen and phosphate fertilization effect the nutrition contents of N,K,P and total amounts of N,K,P as well as outputs obviously. Potassium fertilization effect the nutrition contents of N and total amounts of N,K as well as outputs obviously. Organic fertilization effect the nutrition content of N,P and total amounts of N as well as outputs obviously. The suitable fertilization of CO(NH_2)_2 was shown to be about 48 g per den, Ca(H_2PO_4)_2 14 g~21 g per den , K2SO_4 3 g per den and organic fertilization 80 g per den.
