有机无机肥混合施用对水芹生长及产量的影响

Effect of Mixed Application of Organic and Inorganic Fertilizers on the Growth and Yield of Cress

为探究有机肥与无机肥的混合施用对水芹的根系生长及产量的影响,以大叶水芹为研究对象,设置了不同的有机肥无机肥混合施用处理。结果表明,有机肥无机肥混合施用有助于促进水芹植株的生长以及光合色素含量、干物率和根系活力的增加,其中均以T2(150 kg/667 m^(2)有机肥+25 kg/667 m^(2)无机肥)最佳;根系形态均为单施无机肥(CK)时更发达;此外,有机肥无机肥混合施用可以促进水芹产量增加。随着有机肥的增多,水芹产量表现为先上升后下降的趋势,其中T2(150 kg/667 m^(2)有机肥+25 kg/667 m^(2)无机肥)的产量最高。综上,T2(150 kg/667 m^(2)有机肥+25 kg/667 m^(2)无机肥)时水芹的生长状况及产量最佳。本试验旨在探究有机无机肥的混合施用比例对水芹的生长及产量的影响。试验结果对于水芹高产栽培的肥料施用及管理具有指导意义。

In order to explore the effect of mixed application of organic and inorganic fertilizers on the root growth and yield of cress,large-leaf cress was taken as the research object,and different treatments of mixed application of organic and inorganic fertilizers were set up.The results showed that the mixed application of organic fertilizer and inorganic fertilizer can promote the growth of cress plants and the increase of photosynthetic pigment content,dry matter rate and root vitality,and T2(150 kg/667 m^(2)organic fertilizer+25 kg/667 m^(2)inorganic fertilizer)is the best;the root morphology is more developed when only inorganic fertilizer(CK)is applied;in addition,the mixed application of organic fertilizer and inorganic fertilizer can promote the increase of cress production.With the increase of organic fertilizer,the yield of cress increased first and then decreased,and the yield of T2(150 kg/667m^(2)organic fertilizer+25 kg/667 m^(2)inorganic fertilizer)was the highest.In summary,the growth and yield of cress is the best at T2(150 kg/667 m^(2)organic fertilizer+25 kg/667 m^(2)inorganic fertilizer).The experiment aims to explore the influence of the mixed application ratio of organic and inorganic fertilizers on the growth and yield of cress.The results of the experiment have guiding significance for the fertilizer application and management of high-yield cultivation of cress.
