| 摘 要： | 以贵州省地方品种遵椒二号、绥阳朝天椒、独山皱椒二号为试材,研究不同钾肥处理对不同品种辣椒生长和产量的影响,并对其产值及效益进行了比较分析。结果表明,钾肥能显著提高产量,增强植株长势,增加单株结果数、单果重,但对辣椒的生育期影响不大。在施钾为5、10、15、20 kg/667m2范围内,鲜椒产量比不施钾肥的对照提高67.26~194.35 kg/667m2,增幅15.74%~51.79%,纯收入增长173.16~834.66元/667m2,投产比增长0.01~0.85。贵州地区施钾的最佳量为15 kg/667m2。 |

| Abstract: | The local red pepper varieties,Zunjiao 2,Suiyangchaotianjia and Dushanzhoujiao 2,were tested to investigate the effect of different potassium fertilizer amount on its growth,yield output value and benefit.The results showed that the potassium fertilizer could significantly raise the yield,promote plant growth vigour,increase pepper number per plant,single pepper weight,but it had small effect on the growth period,the fresh yield,and the increase range,net income and output/input with applying 5-20 kg/667m2 of potassium fertilizer were 67.26-194.35 kg/667m2,15.74 %-51.79 %,173.16-834.66 yuan/667m2 and 0.01-0.85 higher than CK without applying potassium fertilizer,respectively.The optimum potassium amount was 15 kg/667m2 in Guizhou. |
