辣椒有机生态型无土栽培专用肥最大利润施肥量的研究

Fertilizing Amount of Organic Hydroponics Ecotypes Special-purpose Fertilizer for Maximum Profit in Pepper

在日光温室内,采用蔬菜有机生态型无土栽培模式,研究了辣椒最大利润施肥量。结果表明,随着专用肥施用量的增加,辣椒单果质量、单株果质量、产量在增加,但单位肥料增产效果则递减。经回归统计分析,辣椒最大利润施肥量为0.148kg/m2(折1.48t/hm2),此时理论产量为6.69kg/m2(折66.9t/hm2),统计分析结果与田间试验结果基本吻合。

In the sunlight greenhouse,using vegetable organic ecotype soilless culture mode,Fertilizing amount for maximum profit of pepper was studied.The results showed that with the increase of the special-purpose fat amount of application,the single fruit weight,fruit of single plant weight,yield of hot pepper increased,but the unit fertilizer increases the production decreased progressively.Through return to statistical analysis,hot pepper maximum profit apply fertilizer quantity is 0.148 kg/m2（1.48 t/hm2）,theory output is 6.69 kg/m2（66.9t/hm2）,statistics analysis result and field test are identical basically.
