Influence of Different Proportion of Base Materials’ and Nutrient Solution on Melon’s Growth

In order to screen out suitable matrix and nutrition solution formelon cultivation,the effect of different proportion of base materials(with ceramsite,sand and perlite)and different proportion of nutrient solution(with high potassium,standard potassium and low potassium)on melon’s growth in soilless cultivation was studied.The result showed that on base materials,when the ratio of ceramsite,perlite and sand was 2∶1∶1,the melon’s height turned to be higher than the others;and when the ratio was 1∶1∶2,the melon’s total chlorophyll content was the highest;furthermore,on nutrient solution,the melon’s plant height,dry weight and chlorophyll content in leaves turned out a positive growth.However,it was not scientific to believe that the more potassium element,the better for melon’s growth,for the excessive potassium element would restrict the absorption of nitrogen.Therefore,compared with the other two nutrient solutions,the standard one was more available for melon’s growth.
