This paper discussed the physics and chemistry of substrates and the effect of different substrates on cucumber growth and development yield and quality by cucumber substrates culture test. The substrates were composed of corn straw, cinder and sterilized chicken excrements with different proportion. The results indicated that:
The unit weight of substrates of treatment 3(corn straw: cinder.sterilized chicken excrements=70:30: 20), 4(corn straw :cinder: sterilized chicken excrements=55:45:20)> 5(...
