摘要：

The effects of different concentrations of nitrate-nitrogen, potassium, calcium and nutrient solution temperatures on the growth and yield of strawberry cv. Red-gauntlet in a nutrient film hydroponic system (NFT) were assessed over a 106 day period. Plants grown in nutrient solutions containing high (14.9 N: 8.5 K: 4.2 Ca mM) and low (7.1 N: 4.6 K: 2.3 Ca mM) concentrations of these elements showed similar growth and yield. Nutrient uptake was not affected by either solution or the 5degreesC difference in solution temperature. Berry production was dependant on plant size and truss number. Calcium deficiency in young leaves was associated with high solution temperatures and not the level of Ca in the nutrient solution.
