Abstract The experiment on nutrient absorption of cucumber in Chinese lean to solar greenhouse was conducted. The results showed that the dry matter and NPK accumulation of cucumber were “S” curve. The largest absorption stage of three essential elements was at full fruit period and over 80% of the total absorption. The 0.2002kg N,0.0921kg P 2O 5 and 0.2322kg K 2O were absorbed in production of 100kg fruit. Their proportion was 1∶0.46∶1.16. The NPK absorption rate was N 2850-4050,P 2O 5 1155-2025,K 2O 2985-47...
