Abstract:
To study effect of water and fertilizer coupling on musk melon in solar greenhouse,with 3 factors and 5 levels quadratic regression orthogonal rotational combination design，irrigation，application amount of nitrogen and potassium application rate and muskmelon in solar greenhouse photosynthetic rate and yield correlation were studied，and a mathematical model was established.The results showed that the photosynthetic rate，yield and irrigation amount，nitrogen application rate and amount of potassium fertilizer were positively correlated.The effect of 3 factors on photosynthetic rate and yield was：X1>X2>X3.When the irrigation amount，the amount of N and K were 2 250 m3/hm2，450 kg/hm2 and 600 kg/hm2，the photosynthesis rate was 12.24 μmol?m-2?s-1，the yield of the melon was up to 70 272.58 t/hm2.The effect of irrigation，nitrogen fertilizer and potassium application on the photosynthetic rate and yield of melon leaves were consistent，and the two had a significant positive correlation.The mathematical model could be used to guide the production of melon in greenhouse.
