1. After the lily was planted from September to October, the bulbs overwintered in the soil and emerged before Qingming Festival in the following year.
(1) loosen the soil and conserve soil moisture to control weeds.
(2) fertilize and cultivate the soil before and after January, pay close attention to the sunny day and spread the border surface with about 1000 kg of pig and sheep ash manure per mu. If conditions are possible, 50-75 kg of rotten cake fertilizer can be used.
(3) clearing the ditch and draining the soil caused the lily bulb to rot. In winter, there are more Rain Water, which is easy to cause stagnant water in the field, so it is necessary to clear the ditch with fertilization and soil cultivation. Before emergence of seedlings in February-March, it can go through intermediate ploughing and weeding, a small amount of fertilizer, and then deepen the field ditch system, so that the drainage is smooth, and there is no water in the field after heavy rain. In case of drought before and after winter and spring, irrigation should be carried out in time to prevent the soil from being too dry, causing the seed bulb to dry up and shrink, affecting underground growth. But do not irrigate too much, it is appropriate to moist the soil.

Second, topdressing is generally applied three times. The first time was around January, 2000 kg of decomposed manure, 50 kg of cake manure and 100 kg of plant ash were applied per mu; the second time was carried out when the seedling height was about 10 cm, and 1500 kg of decomposed human and animal manure was applied per mu.

Symptom: Leaves have round yellowish spots, and the edges of the spots are dark brown. The spots on the petals are round and flaxen. It mainly occurs on the outer surface of the upper part of the scale, but also occurs on the inner surface. It produces irregular, light brown spots in the early stage, then light black brown, slightly depressed, and finally almost black in the diseased part. The tissue shrinks and dries, and the diseased spots can be as deep as several layers of scales, but the outermost scales are the most severely damaged.
