Detailed Explanation of the Fertilizer Requirement Patterns of Lilies Throughout the Growing Period

Nursery Stock 0 views
Understanding the fertilizer requirement patterns of lilies at each growth stage is very beneficial for rational fertilization and promoting high yields. The patterns of lily demand for the three major nutrients: 1. Nitrogen fertilizer: The nitrogen absorption rate of lilies varies at different growth stages. At emergence, the nitrogen absorption rate is 3.5537 probit units, and the cumulative nitrogen absorption percentage is 7.4%, equivalent to 0.201 kg of nitrogen absorbed per mu. This indicates that during the seedling stage, in addition to receiving nutrients from the mother bulb, the plant also needs to absorb a certain amount of nitrogen from the soil. 2. Phosphate fertilizer: At emergence, the phosphorus

Understanding the fertilizer requirement patterns of lilies at each growth stage is very beneficial for rational fertilization and promoting high yields. The patterns of lily demand for the three major nutrients:

1. Nitrogen fertilizer: The nitrogen absorption rate of lilies varies at different growth stages. At emergence, the nitrogen absorption rate is 3.5537 probit units, and the cumulative nitrogen absorption percentage is 7.4%, equivalent to 0.201 kg of nitrogen absorbed per mu. This indicates that during the seedling stage, in addition to receiving nutrients from the mother bulb, the plant also needs to absorb a certain amount of nitrogen from the soil.

2. Phosphate fertilizer: At emergence, the phosphorus absorption rate is 2.4686 probit units, and the cumulative phosphorus absorption percentage is 6.3%, equivalent to 0.039 kg of phosphorus absorbed per mu.

3. Potassium fertilizer: At emergence, the potassium absorption rate is 3.5114 probit units, and the cumulative potassium absorption percentage is 6.99%, equivalent to 0.198 kg of potassium absorbed per mu.

According to the fertilizer absorption patterns of lilies, nitrogen fertilizer should be applied early and heavily; phosphate fertilizer is best used as a base fertilizer; potassium fertilizer should be applied early. The suitable application ratio of the three is 1:0.6:1.
