- 摘要:
- 以“粉的帅2号”番茄品种为试材,以秸秆沼渣和珍珠岩为复合基质,本着材料易得的原则,研究了不同的营养液配方(以北方常用营养液配方为对照)对番茄穴盘育苗的影响,旨在筛选用于秸秆沼渣基质的简易育苗营养液配方。结果表明:在播种后13~28 d,处理T2(即尿素152.3 mg/L,磷酸二氢钾508.76 mg/L,硫酸钾291.67 mg/L,硝酸钙707.00 mg/L),在株高、单株叶面积、地上部鲜重、地下部鲜重上均表现为与CK差异不显著,在播种后33 d,处理T2的株高、茎粗、叶面积、地上部、地下部鲜重均略高于CK,地上部和地下部干重均与CK差异不大;营养液配方T2与对照配方育苗效果相近,不含有硝酸钾、硝酸铵和磷酸,配方简单,原料易得,配置方便,适合在生产中推广应用。
- Abstract:
- Taking‘Fendeshuai No.2’tamato variety as materials,straw biogas and perlite were used as composite matrix,different nutrient solution formulations was designed by the principle of material readily available,to screen for easy plug seedling nutrient solution formula,and tomato plug seedlings trial with northern nutrient solution was used as a control formula.The results showed that,after sowing 13-28 days,treatment T2(152.3 mg/L urea,508.76 mg/L monopotassium phosphate,291.67 mg/L potassium sulphate,707.00 mg/L calcium nitrate)in plant height,leaf area,shoot fresh weight,root fresh weight all showed no significant difference with CK,after sowing 33 days,treatment T2 in plant height,stem diameter,leaf area,shoot and root fresh weight were slightly higher than CK,shoot and root dry weight showed little difference with CK.Nutrient solution formula T2 had the similar effect on plug seedling production with CK,and didn’t contain potassium nitrate,ammonium nitrate and phosphoric acid,it was easy to configure with raw materials and suitable for promotion in production applications.
