Other claims from this paper (15)
- Observation The maximum value of the alkaline hydrolysable N/available P ratio was 7.95 times its minimum value across orchards.
- Observation The maximum value of the alkaline hydrolysable N/available K ratio was 7.60 times its minimum value across orchards.
- Observation The maximum value of the alkaline hydrolysable N/available Zn ratio was 10.58 times its minimum value across orchards.
- Observation The maximum value of the available K/Zn ratio was 18.76 times its minimum value across orchards.
- Observation The maximum value of the available Ca/Zn ratio was 13.47 times its minimum value across orchards.
- Association Alkaline hydrolysable N/available P and available P/Ca were positively correlated with fruit mass.
- Association Alkaline hydrolysable N/available Ca was negatively correlated with fruit mass.
- Association Alkaline hydrolysable N/available Ca and alkaline hydrolysable N/available K were negatively correlated with firmness.
- Association Alkaline hydrolysable N/available Fe had the greatest effect on fruit soluble solids content and was negatively correlated with it.
- Recommendation The optimum soil nutrient element ratios for good apple quality are proposed as alkaline hydrolysable N/available P 1.9 and the other listed ratios.
- Observation Under the optimum soil nutrient ratio proposal, fruit mass of 442.06 g is theoretically achievable.
- Observation Under the optimum soil nutrient ratio proposal, fruit firmness of 13.87 kg/cm 2 is theoretically achievable.
- Observation Under the optimum soil nutrient ratio proposal, fruit soluble solids of 29.37% is theoretically achievable.
- Observation Under the optimum soil nutrient ratio proposal, titratable acid of 0.51% is theoretically achievable.
- Recommendation Reducing soil alkaline hydrolysable N, increasing available K and stable available Fe is the key to improving fruit soluble solids content.
