不同羊粪使用量对番茄品质及产量的影响

Effect of Different Sheep Manure on the Fruit Quality and Yield of Tomato

以充分腐熟的羊粪及尿素和二铵为试材,以最佳尿素和二铵使用量与不同羊粪使用量作为基肥进行温室番茄栽培比较,以期得出最优羊粪使用量。结果表明:处理A(尿素0.15t/hm2+二铵0.45t/hm2)的番茄株高最高(113cm),茎粗也最粗(1.220 4cm);产量也较高,达到103.96t/hm2;但其可溶性蛋白质含量(1.74mg/g)和可溶性总糖(1.48%)含量最低,且亚硝酸盐含量(1.86mg/kg)最高,分别显著性低于和高于其它各处理番茄的品质。处理D(羊粪75t/hm2)的番茄株高较高(106cm),茎粗也较粗(1.206 8cm),叶长最长(15.9cm),单株果数最多,达到17.71个,果实品质较好,产量也较高,达到(100.18t/hm2)。综合考虑番茄产量、品质、种植成本和经济效益等方面,在夏季温室栽培番茄时,推荐使用羊粪做为基肥,最佳使用量为75t/hm2。

Using sheep manure,urea and diammonium as experimental material.The best dosage of the urea and diammonium compared with the different dosage of sheep manure for tomato basal fertilizer in greenhouse were studied.The results showed that the plant height（113cm）,stem diamete（1.220 4cm）,and nitrite content of the treatment A（Urea 0.15t/hm2＋Diamine 0.45t/hm^2）were the highest,its yield（103.96t/hm^2）was higher than others,its content of soluble protein（1.74 mg/g）,and soluble sugar（1.48%）were the lowest and significantly lower than others.The length of leaf（15.9cm）and fruit numbers（17.71）of the treatment D（Sheep manure 75t/hm^2）were the highest,its plant height（106cm）,stem diamete（1.206 8cm）,yield（100.18t/hm^2）and fruit quality was higher than others.We comprehensively evaluated from fruit quality,yield,planting cost and economic effectiveness of tomato.We suggest that75t/hm2 of sheep manure may be suitable for tomato basal fertilizer in greenhouse.
