Effect of Mixed Application of Organic and Inorganic Fertilizers on the Growth and Yield of Cress
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 m2 organic fertilizer+25 kg/667 m2 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/667 m2 organic fertilizer+25 kg/667 m2 inorganic fertilizer)was the highest.In summary,the growth and yield of cress is the best at T2(150 kg/667 m2 organic fertilizer+25 kg/667 m2 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.
