A Detailed Guide to the Latest Growing Environment Requirements for Lilies
Lily bulbs contain a large amount of starch, are edible, and have high edible value. They are mainly an important medicinal material that can moisten the lungs and clear the heart, and are mainly used to treat symptoms such as mental absent-mindedness and insomnia with frequent dreams. It is said that they also have anti-cancer effects. In recent years, large-scale planting has begun, but friends who lack some experience should pay attention to Baihe's planting conditions, and can read the content of the article.
1. Temperature
Lilies prefer a cool environment and are relatively cold-tolerant. Young buds can germinate at 12 degrees, and by 14 degrees they will quickly emerge from the soil. 13 to 18 degrees is the temperature at which stems and leaves grow fastest. During the flowering period, temperatures above 20 degrees and below 30 degrees are best. After that, the bulb enlargement stage requires a temperature of 12 to 14 degrees.
2. Humidity
Lily bulbs prefer a dry, breathable soil environment. The air environment should not be too humid either. Air humidity can be maintained at around 45%, and underground humidity at around 40%. Too much moisture will cause disease, bulb rot, or inhibit respiration and growth. Generally, it should be kept dry so that breathability is good, the soil is not sticky and heavy, and the bulbs can easily expand. Above-ground humidity only needs to be sufficient, since the plant still needs water to survive.
3. Nutrition
Lilies need a lot of fertilizer. Generally, potassium fertilizer is needed the most, followed by nitrogen fertilizer. When the above-ground plant is all green, photosynthesis needs nitrogen fertilizer to promote leaf growth. However, do not apply nitrogen fertilizer in the later stage. For a period before harvest, the above-ground part may already have withered. In the early stage, apply nitrogen fertilizer, about 200 jin of compound fertilizer per mu, with nitrogen fertilizer making up the largest proportion. Then, during the bulb enlargement stage, apply topdressing once, generally 300 jin of potassium fertilizer per mu or about 400 jin of plant ash per mu. Sometimes attention should be paid to adding some phosphate fertilizer to ensure no nutrient deficiency.
4. Light
10 hours of light per day can be satisfied by most planting areas, but strong light is not good for lilies, as it easily sunburns the leaves and affects nutrition. Moreover, exposing the soil to too much dryness or drought will cause the bulbs to stop expanding and growing, and the plant to lose water, affecting quality. It may even dry the lilies to death, since the underground bulbs are mainly composed of water.
5. Soil
Lilies are especially afraid of water accumulation and flooding, and are particularly prone to root rot, resulting in partial or complete rotting. Therefore, the planting site must be deep, dry, well-drained, gently sloping land. Do not plant in sticky, compacted, low-lying land or paddy fields. It is best to plant on land at the foot of hills that is higher than the irrigation of paddy fields.
The above-ground part of the lily is short and deep green, while the underground bulb fears water and waterlogging. Therefore, the entire growing environment should be set around the growth characteristics and needs of lilies. Then lilies grown under these conditions will have better quality, and growers can also reduce some unnecessary losses.
