施用多功能生态肥对番茄生长和经济效益的影响

为了解决敦煌市蔬菜品质差、产量低而不稳的疑难问题,为温室蔬菜安全生产提供技术支撑,进行了多功能生态肥对番茄生长和效益的研究。结果表明:多功能生态肥原料间的主次效应(R)是:B(番茄专用肥,R=26.92)>A(有机生态肥,R=24.29)>C(土壤消毒杀菌剂,R=12.55);最佳配方组合是:m(有机生态肥)∶m(番茄专用肥)∶m(土壤消毒杀菌剂)=0.8186∶0.1774∶0.0040。施用多功能生态肥与施用传统化肥比较,番茄早疫病发病率和可滴定酸分别降低66.67%和28.00%;株高、生长速度、茎粗、地上部分鲜质量和地上部分干质量分别增加4.45%、3.81%、7.61%、8.40%和6.67%;单果质量、单株果质量、产量、可溶性糖和VC含量分别增加6.23%、9.26%、8.82%、27.46%和23.65%;施肥利润和肥料投资效率分别增加1.84×10^4元/hm^2和1.23元/元。在甘肃省敦煌市肃州镇的温室土壤上施用多功能生态肥,改善了番茄品质,提高了番茄的经济效益。

Effects of Multi-functional Ecological Fertilizer on Tomato Growth and Economic Benefit

Abstract: In order to solve the problem of poor quality, low and instable yield of vegetables in Dunhuang city, and provide technical support for the safe production of greenhouse vegetables, the effects of multi-functional ecological fertilizer on tomato growth and benefit were studied. The results showed that the primary and secondary effect (R ) of the multi-functional ecological fertilizer was: B (tomato special fertilizer, R=26.92) > A (organic ecological fertilizer, R=24.29) > C (soil disinfectant, R=12.55). The best combination was m (organic ecological fertilizer) : m (tomato fertilizer) : m (soil disinfectant) = 0.818 6 : 0.177 4 : 0.004 0. The incidence of tomato early blight and titratable acid content decreased by 66.67% and 28.00% compared with conventional fertilizer. Plant height, growth rate, stem diameter, fresh weight and dry weight of aboveground increased by 4.45%, 3.81%, 7.61%, 8.40% and 6.67%, respectively. Single fruit weight, fruit weight per plant, yield, soluble sugar and VC content increased by 6.23%, 9.26%, 8.82%, 27.46% and 23.65%, respectively. Fertilization profit and fertilizer investment efficiency increased by 1.84×104 yuan/hm2 and 1.23 yuan/yuan, respectively. The application of multi-functional ecological fertilizer on greenhouse soil in Suzhou town of Dunhuang improved the quality and economic benefit of tomatoes.
