| Abstract: In order to solve the cultivation problem of soil in greenhouse, the agricultural organic material substrate was used to compare the application effects of the total nutrition substrate on cucumber in greenhouse. In this experiment, ‘Jinzao No.1’ cucumber was took as the test material, and the fermented decomposed cow dung, corn stover, slag and rice husk were used as the basic raw materials, and urea and potassium sulfate were added according to certain proportion for forming fi ve different formulas, studying the effects of different proportions substrate on cucumber plant growth, fruit yield and quality and screening out the cultivation substrate formula that was suitable for cucumber growth. The soil was took as the control. The results showed that under the formula S1T4 (V(masterbatch)∶V(sputum)=2∶1, m(potassium)∶m(sulphate)=0∶0) and S1T5 (V(masterbatch)∶V(sputum)=2∶1，m(potassium)∶m(sulphate)= 1.9∶0.55), the cucumber grew well with high yield and quality and the substrates had good physical and chemical properties. The two substrate formulas could simultaneously achieve only watering and no top dressing in the whole production season, which were suitable formula for cucumber substrate cultivation. The all test indexes of the S1T3 (V(masterbatch)∶V(sputum)=3∶1，m(potassium)∶m(sulphate)=2∶0.27) were lower than the control. Therefore, the S1T3 formula was not suitable for the cucumber cultivation substrate. |
