采用大棚栽培方式,研究了自制包膜控释复合肥对大棚辣椒产量、品质及植株生长的影响。结果表明,与单施普通复合肥相比,施用等量包膜控释复合肥的辣椒增产效应最大、增产率达157.28%,施用70%包膜控释复合肥、70%包膜控释复合肥+30%普通复合肥、50%包膜控释复合肥+50%普通复合肥也分别增产34.27%、150.45%和67.43%,且施用包膜控释复合肥或与普通复合肥混配施用的辣椒Vc、可溶性糖含量及植株生长状态亦明显高于或优于100%施用普通复合肥,说明包膜控释复合肥对辣椒的增产以及改善营养品质和植株生长效果显著。
Based on a growing study in plastic shield trellises, the effect of controlled-release compound fertilizers manufactured by our lab on the yield and quality of pepper were investigated. The results showed that the fertilizers can markedly improve the yield and the quality of pepper. On condition of the same amount of fertilizer, the yield of pepper with coated fertilizer treatment was 157.28% higher than thatwith non-coated fertilizer treatment. The yield of pepper with 70% fertilizer and blend treatments increased 34.27%, 150.45% ,67.43% higher than those with non-coated fertilizer treatment, respectively. The contents of Vc, Soluble sugar, the plant height and fresh biomass weights of pepper applied with coated fertilizer treatments were also improved.
