大棚甜瓜长效缓释专用肥的减肥增收效果

Preliminary report on long term slow-release special fertilizer for muskmelon in greenhouse

为研究大棚甜瓜长效缓释专用肥的施肥方法,设置专用肥作基肥、专用肥作基肥+追肥、传统施肥和淋水对照4个处理,以比较不同处理对大棚甜瓜产量、品质和经济效益的影响。结果表明,专用肥作基肥+追肥处理的甜瓜平均单果质量(2.67 kg)、667 m^2产量(3 035.29 kg)、商品率(91.73%)、667 m^2产值(19 250.71元)和利润(15 486.81元)最高,可溶性固形物含量(15.56%,ω)仅次于传统施肥处理。长效缓释专用肥的应用具有显著的减肥增收效果,符合当前减肥减药及省工简约化栽培的生产发展方向,对降低当前滥施肥料所造成的土壤污染具有重要促进作用,建议进一步加大力度进行试验示范和推广。

In order to study the muskmelon slow-release fertilizer application method, experiments were conducted on four treatments of A（special fertilizer as base-fertilizer）, B（fertilizer basal-dressing ＋ topdressing）, C（traditional fertilization） and D（water） as CK, the effect of different treatments on the yield, quality and economic benefit of greenhouse muskmelon were analyzed.The results showed that the average fruit weight（2.67 kg）, yield（3 035.29 kg per 667 m^2）,commodity rate（91.73%）, output value（19 250.71 yuan per 667 m^2）and profit（15 486.81 yuan per 667 m^2）of melon which treated by B were the highest, and the soluble solids content of which was only next to that of C.The application of slow-release special fertilizer has significant effect on reducing fertilizer amount and increasing income and in line with the current production and development direction of reducing amount of fertilizer and pesticide and labor-saving.It has an important role in reducing soil pollution caused by the abuse of fertilizer, it is suggested that further efforts should be made to carry out the experiments, demonstrations and popularization.
