Technical key points for preventing waterlogging during the rapid growth period of lilies
Pre-emergence management: From sowing to around emergence, the main tasks are clearing ditches and draining water well, ensuring the lily field is neither too dry nor waterlogged, and that there is no low-temperature freeze damage, so as to ensure normal growth of the bulb roots. Seedling-stage management is generally during late April or early May; when the seedlings are about 10 cm tall, apply generally 25-50 kg of decomposed rapeseed cake fertilizer per mu, or 30 loads of decomposed pig manure and urine (do not apply chemical fertilizers containing fluorine or chlorine, and even more so do not apply pig manure and urine that has not been composted), applied in furrows or holes, 6-7 cm away from the lily seedlings. Applying too close can easily cause "seedling rot," while applying too far away makes the fertilizer prone to loss. At the same time, during the seedling stage, depending on labor availability, carry out timely cultivation 1-2 times; where conditions permit, cultivate after rain (be sure to cultivate shallowly), with a cultivation depth of 4-6 cm, deeper between rows and shallower between plants.
