The Law of Fertilizer requirement in Lily's Life
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.

Lily blight
Blight is an important disease of lily, which is widely distributed, mostly occurs in the south, and occasionally occurs in the protected areas in the north. Usually 5% 10% of diseased plants affect the production of lilies to a certain extent, which can reach more than 30% when heavy, resulting in plant death and significantly affecting the yield and quality of lilies. Symptoms: the disease can affect all parts of the lily. The stem infected with disease, initially showed water-immersed light brown to green-brown rot, and gradually expanded up and down, causing the plant to die or fold. The leaves were infected with disease, and the small spots were immersed in water, and then developed into gray-green to dark green spots.

Control of lily leaf blight
Symptoms: round or oval disease spots appear on the leaves, varying in size and more than 2mm in length. Light yellow to light brown. In some varieties, the spot is light brown, surrounded by a clear reddish-purple edge, and in wet conditions, the spot is quickly covered with gray mold. When the disease spot is dry, it becomes thin, fragile, transparent and generally grayish white. When serious, the whole leaf withered and died. When the stem is infected, it is rotten and broken from the infection place, and the bud turns brown and rotten. When the flowers are speckled brown and wet, they quickly turn into a sticky mass and are covered with gray.
