The high yield of lily needs three changes

First, switch to inferior seed stems for high-quality seed stems to select superior varieties such as Longya Lily. Lily needs to buy seeds from other places, which is an important measure for lily rejuvenation. The selection of seed-stem with little or no poison is the key to high-yield cultivation of lily. At the same time, we should pay attention to the selection of stout and plump seed stems. Seed ball propagated by scales or seed ball directly from mother ball.

Second, change sowing too early for timely sowing, sowing too early is prone to drought, often causing rotten seeds, and the temperature in early August is high, which is not conducive to the release of dormant period of lily seed stems. After sowing, roots often do not grow, browning and rotten seeds are easy to occur. Lily should be sown from late August to early September. Lily seed stems dug back or bought back too early can be stored indoors in a cool place with sand stratification to prevent premature seeding. In case of drought after sowing, it can be covered with straw and other crop straws when the soil is wet, which can reduce the temperature by 2℃~3℃, reduce soil moisture evaporation, and also play a role in heat preservation in winter. If the soil is dry after sowing, furrow irrigation is used to keep the soil moist.

3. Change wide bed culture to narrow bed culture Lily is easy to infect virus disease, leaf blight, blight, root rot and other diseases are also serious. The occurrence of these diseases has a lot to do with humidity. The practice proved that changing wide bed cultivation to narrow bed cultivation and continuous cultivation as rotation were the key measures to control fungal diseases. According to the width of about 1.5 meters to do the ridge, open the ridge ditch, the ditch and the main ditch. Furrows 25 cm wide and 20 cm deep; surrounding furrows 30 cm wide and 25 cm deep; main furrows 40 cm wide and 30 cm deep, so that there is no accumulated water in the furrows after rain.
