The yield of lily is not stable, and some plows have been “disastered†as soon as they die. There is almost no yield. When lilies are planted for high yields, they must focus on "four reforms."
1. Use inferior stems as good quality stems. Lily should be selected for the species of Longya Lily and other fine varieties. The typical characteristics of the Dragon's-tooth lily are: the squash hugs tightly, the scales under the hypertrophy, the upper sharp curve, shaped like a dragon melon, color like ivory. The stems on the ground are large and thin with no buds and no balls. Lily needs to be purchased from different places. This is an important measure for rejuvenation. But pay attention to buying seeds from high altitudes and cool climates. For example, when purchasing plants from low elevations in the hilly area, due to the high temperatures during the growing season of the lily, the stems usually carry more virus. After the seedlings are sown, the virus disease occurs seriously, the leaves shrink or the mosaic leaves appear, and the dead seedlings are early. , low yield and poor quality. The use of less toxic or non-toxic stems is the key to high-yield cultivation of lilies. At the same time pay attention to the use of thick and fat, no pests, no "bottom out" phenomenon of stems. Use scales to breed bulbs or directly use bulbs in the cue ball as seeds.
2. Change sowing too early for timely sowing. In recent years, some hills have sown lily in July and are prone to drought, which often causes bad seeds. The high temperatures in July and early August are not conducive to the release of the dormancy period of lily species. After sowing, they often do not grow roots and are prone to oxidative browning and rotten species. Soil drought causes dehydration of the stem scales. It is advisable to plant the lily from late August to early September. Within this range, early sowing should be conducted where the temperature is low, and vice versa. Lily stems that have been excavated or restocked prematurely can be stored in a cool place on the inside with sand and stratification, and sown at the time to prevent early sowing. After sowing, in case of drought, the soil can be moistened, immediately covered with straw and other crop stalks, generally cooling 2 ~ 3 °C, and reduce the evaporation of soil moisture, winter can also play a role in insulation. Coverage thickness 7 ~ 10cm, such as soil drought after sowing, the use of furrow irrigation methods to keep the soil moist.
3. Change the width of the planting cultivation to narrow planting. The peasants' response to Lily’s most difficult “waiting†is because Lily’s virus diseases, such as leaf blight, blight, diseases, and root rot, are also prone to serious disease. Simply rely on chemical control, the effect is not ideal, agricultural control is the key. These diseases have a lot to do with humidity. From April to June, it was a period of rainy weather. Most of the hills were poorly drained, soil moisture and inter-plant humidity were relatively large, so the occurrence was more serious. Practice has shown that changing the cultivation of broadleaf hoe is a key measure to control the fungal diseases described above as narrow-narrow planting and replanting as rotation. Generally according to the width of about 1.5m tiller, open good sulcus, gutter and main ditch. The sulcus width is 25cm and the depth is more than 20cm; the width of the sulcus is 30cm, and the depth is more than 25cm; the width of the main sulcus is 40cm, and the depth is more than 30cm, so that there is no water accumulation in the ditch after rain.
4. Improve disease prevention methods. Some puppies do not use medicine until the disease occurs. It is often too late. Diseases are more important than prevention, and they should be prevented and controlled. In addition to the above methods, it is also necessary to control nitrogenous fertilizers, increase phosphorus and potassium fertilizers, and use drugs at the initial stage of disease occurrence. For virus diseases, it is necessary to prevent and control good maggots, and use bacteriocin or virus A for 3 to 4 times in the early stage of disease; for damping-off, leaf blight, and epidemic diseases, 1:2:200 can be used in the absence of disease. The Bordeaux mixture was applied once every 7-10 days.
