- 摘要:
- 以“中农21号”黄瓜为试材，研究了设施条件下不同时期基质不同含水量对黄瓜营养生长、产量和光合特性的影响。结果表明：基质含水量在60%～70%时适宜黄瓜的营养生长、产量提高和光合特性的发挥;通过回归方程模拟优化，适宜的基质含水量（绝对含水量）区间是61%～74%，其中，在黄瓜生长的前期、中期基质含水量为68%时，黄瓜产量最高；黄瓜生长的后期基质含水量为69%时，黄瓜产量最高。
- Abstract:
- Taking‘Zhongnong No.21’as material，the influence of different water content of substrate in different period on cucumber growth，yield and photosynthetic characteristics in facilities condition were studied.The results showed that the water content in 60%~70% was suitable to vegetative growth，yield and photosynthetic characteristics.Through the regression equation simulation optimization，suitable substrate water content range were 61%~74%，among them，in the early stage of cucumber growth period，the suitable water content was 68%，under this condition had the highest yield of cucumber；in the late stage，the suitable water content was 69%，and had the highest yield.
