1. Good soil structure and drainage are critical to the success of cultivation. The soil needs sufficient moisture, nutrients and oxygen. 2. In the six weeks before planting, soil samples should be collected to obtain information on soil pH, total salt content, and chlorine level, and determine soil fertility. 3. The appropriate pH level is very important for the growth of lily roots and the absorption of mineral nutrients. 4. Lilies are very sensitive to salt. If the soil contains too much salt and chlorine, rinse the soil thoroughly before planting. 5. If fertilization is required, give enough time three weeks before planting. Lilies grow in all soils. However, it is important to ensure that the cultivated soil has a good structure, especially the upper layer, and that good irrigation is maintained throughout the entire growth stage. Soils with strong stickiness are not suitable for cultivation of lilies. It is better to keep the humus in the soil base layer 30 cm thick. It can make the soil moisture contain enough oxygen to increase the ventilation of the upper layer of soil. In addition to water and nutrients, oxygen in the soil is also very important for lily development. The land with insufficient surface ripening was improved by using rice straw, rice bran, pine leaf, and peat moss. The appropriate soil pH is very important for the development of lily roots and the absorption of mineral nutrients. If the pH is too low, excessive mineral nutrients, such as manganese, sulfur, and iron, will be absorbed; however, if the pH is too high, the absorption of phosphorus, manganese, and iron will be insufficient, resulting in deficiency of the disease. For Asian lily and Aquilaria hybrids, the pH of the soil is normal from 6 to 7; for eastern hybrids, the pH of the soil should be between 5.5 and 6.5. To reduce the pH, it is possible to apply it to the topsoil. peat. Application of urea and ammonium N fertilizer can also reduce soil pH. Lilies are shallow-rooted plants, but it requires that the soil must be well-irrigated and at least 40 cm deep. Special attention should be paid to the fact that if the salt content in the soil is too high, it is often necessary to flood the soil between the two crops. Lily is very sensitive to salt, soil salt content is too high to inhibit root absorption of water, which will affect the plant stem length. There are three factors affecting soil salinity: 1. Salinity of fertilized material 2. Salinity of irrigation water 3. Salinity of former crops Six weeks before planting bulbous flowers, soil samples from planting fields are to be extracted. Get information on soil pH, total salt content, total chlorine content, and total mineral nutrients. If the salt or chlorine content is high, it should be flushed with appropriate water, and the soil must be thoroughly rinsed, as this will prevent the degradation of the soil structure. When using fresh organic fertilizer, ensure that the salt is not too high, and be careful not to use inorganic fertilizers in large quantities at the same time.
