The Law of Fertilizer requirement in Lily's Life

Last Updated: 2024/11/05, Understanding the law of fertilizer requirement of lily at each growth stage is very beneficial to rational fertilization and promoting high yield. The demand law of lily for three elements: 1. Nitrogen fertilizer: the nitrogen absorption rate of lily was different at different growth stages. The rate of nitrogen absorption at seedling emergence is 3.5537 probability units, and the cumulative percentage of nitrogen absorption is 7.4%, which is equivalent to absorbing nitrogen 0.201KG per mu. It shows that in addition to receiving nutrients from the mother at the seedling stage, it is also necessary to absorb a certain amount of nitrogen from the soil. two。 Phosphate fertilizer: phosphorus at seedling emergence

Understanding the fertilizer requirement law of lily at each growth stage is beneficial to rational fertilization and high yield. The law of lily's demand for three elements:

1. Nitrogen fertilizer: Lily different growth stages of nitrogen absorption rate is different. The rate of nitrogen uptake at emergence was 3.5537 probability units, the percentage of nitrogen uptake accumulation was 7.4%, equivalent to 0.201KG nitrogen uptake per mu. It indicated that the seedling stage not only received nutrition from mother, but also absorbed a certain amount of nitrogen from soil.

2. Phosphorus fertilizer: phosphorus uptake rate at seedling stage is 2.4686 probability units, phosphorus uptake accumulation percentage is 6.3%, equivalent to phosphorus absorption of 0.039KG per mu.

3. Potassium fertilizer: the rate of potassium absorption at seedling emergence is 3.5114 probability units, and the cumulative percentage of potassium absorption is 6.99%, which is equivalent to 0.198KG potassium absorption per mu.

According to the law of lily fertilizer absorption, nitrogen fertilizer should be applied early and heavily; phosphorus fertilizer should be applied as base fertilizer; potassium fertilizer should be applied early. The ratio of the three is 1: 0.6: 1.
