Seed selection Choose healthy plants that grow for 4 to 5 years, strengthen the management of fertilizer and water, and insert some stalks or branches next to the plants as a stand, so that the tendril climbs on it to avoid wind breaks. It blooms and bears fruit in May, and the plants on the ground gradually wither in late May, but the fruit is still immature. It can be taken away with the fruit and stored in a ventilated place. When it matures, pay attention to mold prevention. Dry until the fruit turns from green to yellow. When the cracks are cracked, pick the fruit and rub out the seeds to be planted. Site selection It is cultivated with deep soil layer, loose and fertile soil, well-drained humus or sandy loam. Avoid saline-alkali soil and sticky heavy soil, low-lying waterlogged or dry land is not suitable for planting. It is best to be close to the water source to facilitate irrigation. In spring, after the ground has thawed, the ground must be turned carefully, raked, and prepared. Press 1 to 1.2 meters in width and 50 cm in the working track as a border. The surface soil of 7 to 8 cm deep on the border surface is collected on the working track to make the border into a flat bottom groove, and then compacted with a roller to become a hard bottom. This is convenient for harvesting, preventing omissions, and can play a role in water and fertilizer retention. After the bottom is compacted, a 5-7 cm thick base fertilizer is laid on top. Pig manure is better, as well as horse manure and humus. Each mu can be mixed with 20-25 kg of superphosphate, agricultural fertilizer must be fully decomposed and sieved before applying. Cover the base fertilizer with 2 ~ 3 cm thick soil to plant. Field management Pull out when there is grass, to prevent weeds from competing for water, fertilizer and weeding depth, subject to not injuring the bulbs; weeding 2-3 times during the growing period and withering period; before emergence, use 50% simazine or atrazine per mu Treat soil with 0.15 kg and 200 kg with water. Fertilizing and irrigating and planting fritillary stalks are better than rotten pig manure. Kang cave soil, small ash and other alkaline fertilizers are avoided. Hijab manure is applied twice a year, the first time after the harvest of the large bulbs before freezing, the agricultural fertilizer applied should be finely crushed and spread on the border surface about 3 cm thick. In the first and middle of May, during the peak season of fritillary growth, calcium phosphate and diammonium phosphate can be applied, and then water can be poured, and the soil can be loosened in time, and foliar fertilizer can also be applied. After removing the flower bud fritillary buds, if you do not keep the seeds, you should remove them in time. If you plan to keep the seeds, you can properly thin the buds. Pest Control Rust usually occurs on the back of the leaves and on the stem, and golden spores appear, which turn into yellow powder after maturity and spread by the wind. In severe cases, the plants wilt early. Prevention and control method: strengthen field management; spray 250 times of dichlorfen sodium 2 to 3 times before the onset, every week interval, or use 25% powder rust rather wettable powder 1500 times solution. Bulb rot is prone to occur when the temperature and humidity are too high or the plants are too dense. Bulb damage is also prone to this disease. Prevention methods: prevent excessive soil moisture; before planting, the bulbs are soaked in 20% formalin for 1 hour. The underground pests that harm Fritillaria include grubs, golden needleworms, mole crickets, and other control methods: use fully decomposed manure, and irrigate with 80% of the trichlorfon 800 times during the occurrence period. Harvesting and processing Ping fritillary is harvested 2 to 3 years after planting, from late May to early June (before and after mango species). When the harvest is late, the bulbs are puffed. When harvesting, excavate from one end of the border, use the sieve after harvesting, large processing, small for planting, or directly stay in the border to continue growing for the next year. Generally 500-750 kg of fresh goods can be harvested per mu. The fritillary to be processed is first washed off the soil, and then processed. There are two methods of drying and drying; drying, placing the fritillary on the mat on a sunny day, mixing an appropriate amount of cooked lime, and drying it in about 4 to 5 days. Drying, firstly kang noodles are sprinkled with a layer of cooked lime or small ash, then put the large fritillary on the kang head, the small ones on the kang tip (single swing can not be overlapped), then sprinkle a layer of lime on top, kang temperature is hot It is advisable to gradually increase the Kang temperature, but it should not be higher than 40 ° C. If the temperature is too high or it is placed too densely, "oil particles" are generated. When the fritillary reaches 80% dry, the temperature should be gradually reduced. Toss frequently. It will dry out after 18 ~ 24 hours. Sift out the fritillary and put it in a sack, pull up the four corners and move it in series to remove impurities, and it will be milky white.
