How to grow Fritillaria? What do you need to pay attention to when planting Anhui Fritillaria?

Planting medicinal plants is similar to planting crops. The general steps of planting crops, such as soil preparation, sowing, planting, topdressing and pest control, are also the basic steps of planting traditional Chinese medicine. Fritillaria as a unique valuable medicinal materials in Anhui Province, its planting method is basically the same as Fritillaria, then, Fritillaria is how to plant it? What do you need to pay attention to?

Fritillaria anwanensis is suitable for the humid environment in the south of yangtze river. During the whole growth period, it needs less water for cultivation before the year, and more water before seedling fall after emergence in the next year. The soil with sufficient light and high sediment concentration is very suitable for its growth. Clay soil drainage is not smooth, water content is too large, easy to cause underground stem rot; and sand content is too large soil, poor water retention, it affects yield.

1. Soil preparation and bedding. Spread chicken manure or pig manure evenly on the selected fields, and apply 50 kg of calcium superphosphate, 10 kg of potassium chloride, 5 kg of 10% carbendazim powder and 1 kg of trichlorfon powder (mixed with fine sand) every 667 square meters (1 mu). After ploughing, expose to the sun, and then break the soil into tortoise-back shape according to the width of 1.3 meters, and open drainage ditches around it to facilitate drainage.

2. Sowing. From late August to early September, transverse furrows are opened on the ridge surface of intensive cultivation according to the row spacing of 10-14 cm, and the depth of the furrows is 3-4 cm. Then, the seed stems of Fritillaria tenuifolia are placed into the furrows every 4-8 cm (plant spacing) like garlic seeds. When planting, single petals and cut petals are adopted according to the size of the seed stems. The long petals can be crossed, and the round shells can be directly divided into petals. Then cover the soil flush with the surface of the ridge, spray butachlor and then apply a little leveling pressure. Cover the ditch with shellfish seeds to keep moisture and prevent rain erosion.

3. Intercropping. The growth period of Fritillaria tenuifolia is short, but it lasts relatively long in the field. Therefore, shallow root crops such as radish, potherb mustard and cabbage can be interplanted after shellfish is planted into soil. These crops have a short growing season and can be harvested around late December. At this time, Wan Bei has not yet emerged or just emerged, and Wan Bei can also absorb some fertilizer when fertilizing. After harvesting interplanting crops, winter fertilizer is specially applied to Wanbei.

4. Manage topdressing. In spring, manual weeding, ditch cleaning and draining, flower picking and topping should be carried out. In summer, in case of drought, timely irrigation, shallow irrigation on sloping fields, running irrigation in fields, sprinkler irrigation is better, after rain, especially after heavy rain, ditch drainage should be timely cleared.

After Wan Bei emerges, topdressing is applied once a month, 750 kg of thin human urine and feces or 5 kg of urine in rainy days are applied every 667 square meters.

5, pest control

(1) The insect: This insect damages the bulb and causes the plant to wilt and die. Poisoning was carried out by treating the soil with 5% chlorine powder or watering the roots of shellfish seedlings with 1:30 leaf smoke solution (adding 500 trichlorfon).

(2) Gray mold: spray 65% zinc wettable powder 400 times solution before the onset in late March, or use rot frost extinction (Tianjin production, new generation pesticide) according to the amount of water, spray once every 10 days, a total of 3-4 times.

(3) Black spot disease: This disease is easy to occur in many rains, and the control method is the same as gray mold.

6. Harvesting and processing

When the shell leaves are withered in the middle and late May, carefully dig out the underground bulbs in sunny days, remove the fibrous roots, soil, stems and leaves, wash and dry them, fumigate them with sulfur for 10 hours, and then sample and inspect them. Cut the bulbs into two pieces with a knife and apply iodine on the cut surface. If the cross section turns white, it has been fumigated thoroughly; if the cross section is blue, it has not been fumigated thoroughly, and fumigated again. After fumigation, drying or drying, screening impurities, sealing packaging, can be sold.
