【摘要】 以草莓品种"波特拉"为试材,研究了塑料大棚不同土壤有机质和不同全氮条件下施用不同量有机肥料对草莓品质、草莓根层土壤硝态氮含量变化及对草莓产量的影响。试验结果表明,在中等有机质和中等全氮含量条件下,土壤有机肥用量以不超过6t为宜,土壤有机质和全氮含量丰富土壤条件下,有机肥用量不应超过4t。随着有机肥用量增加草莓根层硝态氮含量随着增加,本项研究表明草莓根层硝态氮含量在60mg/kg左右时,草莓产量较高。更多还原

【Abstract】 The strawberry variety "pautrat" as test materials,studied the plastic greenhouse with different organic matter and soil total nitrogen under the condition of applying different organic fertilizers on fruit quality and change of root layer soil nitrate content in strawberry and effect on yield of strawberry.The experimental results show that the secondary organic matter and total nitrogen in soil conditions.Organic fertilizer with no more than 6t,the soil organic matter and nitrogen rich soil,organic fertilizer dosage should not exceed 4t.with organic fertilizer increased the nitrate content of strawberry root layer increased with the increase of the study showed that strawberry root nitrate content was about 60mg/kg,the yield of strawberry high.更多还原
