花溪辣椒测土配方施肥试验

对花溪湖潮乡辣椒氮磷钾配方施肥研究结果表明,氮中量、磷钾高量或低量的配方处理对辣椒生育期无明显影响,低量氮磷钾配方和习惯施肥辣椒有早衰现象,不施肥处理的辣椒早衰更明显。经济性状以中氮低磷高钾效果最好,其果长达到11.95 cm,果粗1.2 cm,干重为64.2 g/10个;产量以高量氮磷钾最高,为188.9 kg/667m2,中氮低磷高钾次之,为183.7kg/667m2,两者差异不明显。中氮低磷高钾的配方既可使辣椒增产,经济效益最高,又能提高辣椒肥料利用率,值得推广应用。

Effects of 5 Different Formulation Application Methods on Economical Characters and Yield of Pepper(Huaxi Local Variety)

The experiment was conducted to investigate effects of five different formulation application methods on economical characters yield of pepper(Huaxi local variety).The results showed that the pepper length,diameter and dry weight of the treatment with applying 40 kg/667m2 of urea,30 kg/667m2 of calcium super-phosphate and 30 kg/667m2 of potassium chloride were 11.95 cm,1.2cm and 64.2 g/10 peppers respectively and yields of the treatments with applying 55 kg/667m2 of urea,50 kg/667m2 of calcium super-phosphate and 30 kg/667m2 of potassium chloride,and 40 kg/667m2 of urea,30 kg/667m2 of calcium super-phosphate and 30 kg/667m2 of potassium chloride were 188.9 kg/667m2 and 183.7 kg/667m2 separately.Therefore,the formulation application technique of 40 kg/667m2 of urea,30 kg/667m2 of calcium super-phosphate and 30 kg/667m2 of potassium chloride can be popularized in production of pepper(Huaxi local variety).
