Ophiopogon planting time Ophiopogon japonicus growth cycle

Ophiopogon japonicus will bloom some flowers when it is flourishing. Dig it out when receiving the goods, and you will see its most valuable part-the stem. This part is usually used in medicine. So what else do you know about Ophiopogon? Let's have a look!

Planting time of Ophiopogon

The spring seed of Ophiopogon japonicus is suitable for sowing around March to August in the north and from February to September in the south. The climate temperature is different in different places, and the best time to sow Ophiopogon japonicus should be judged according to the actual temperature of its own region. The temperature is too high or too low.

Ophiopogon japonicus growth cycle

The growth cycle of Ophiopogon japonicus is one year. It will be planted in March and April today, and we can start digging at the end of next year.

Planting skills of Ophiopogon japonicus

1. Seedling preparation and treatment. Ophiopogon japonicus is propagated by separate plants. Before and after the Qingming Festival in Sichuan, from the Beginning of Summer to Grain in Beard in Zhejiang Province, when digging Ophiopogon japonicus, the dark green and robust plants were selected, the tuberous roots and fibrous roots were chopped off, divided into individual plants, and the residual whisker roots were cut off. Cut off part of the stem base (with white heart on the cross section of the rhizome, leaves do not spread as the degree), plant immediately. If it cannot be planted in time, it is necessary to "raise seedlings". Soak the stem base of the seedlings in clear water so that they can absorb enough water, then stand on the dug loose soil in the shade, and cover the soil around for preservation. If the temperature is too high, you can water it once a day or every other day. The time of raising seedlings is no more than 7 days.

2. Planting. Sichuan in April and Zhejiang in May, choose sunny or cloudy days. Sichuan is planted with trench strips, with a row spacing of about 15 cm and a depth of about 5 cm. First apply thin pig manure water in the ditch, and then plant seedlings according to the plant spacing of 6-9 cm, 3 plants in each clump, and cover the soil after planting, so that the seedlings stand upright and firm, so that the seedlings are straight and straight. Zhejiang adopts hole planting, hole depth is 3-5 cm, row spacing is 25 cm, plant spacing is 15 cm, and 9-10 seedlings are planted in each hole. Cover without base, compacted.

3. Fertilization. Sichuan is generally topdressing 3 times for 4 times. For the first time in July, 1200 kg of human and animal dung water and 25 kg of rotten vegetable cake were applied per mu. For the second time, 1500-2000 kg of human and animal manure water, 40-50 kg of rotten vegetable cake and 75 kg of ash were applied per mu in the first and middle of August. The third time in the first ten days of November, 1500-2000 kg per mu of human and animal manure water, 25 kg of vegetable cake, 75 kg of fire ash or 20-25 kg of calcium superphosphate, and the fourth time in the late February of the second year after planting, 2000-2500 kg of pig manure water per mu, urea 5 kg, calcium superphosphate 7 kg, potassium chloride 5 kg. Fertilization in Zhejiang is slightly different from that in Sichuan. There is a habit of "early application of root fertilizer and heavy application of spring and autumn fertilizer". When Ophiopogon japonicus was planted for half a month, combined with drought resistance, 700 kg of light human and animal fertilizer and 10 kg of superphosphate were applied per mu to promote early rooting, multiple roots and early tillering. After July, 1200 kg of human and animal feces and urine and 15 kg of superphosphate were applied per mu. Spring and autumn are the periods of root expansion and a large number of tillers, so phosphorus and potassium fertilizer should be applied again. It was applied once in March and September, 50kg of superphosphate or 100kg of cake fertilizer per mu, 1200 kg of human feces and urine, and 150,200kg of plant ash. From then on, fertilize 2-3 times a year.

Harvesting and processing of Ophiopogon japonicus

1. Ophiopogon japonicus was harvested in the first and middle April of the second or third year after planting. Choose a sunny day, plough to a depth of 25cm to make Ophiopogon turned out, or dig up clumps of Ophiopogon with a hoe, shake off the soil, cut off roots and fibrous roots, put them in baskets, and scrub the sand with your feet in running water.

2. Processing method: put the washed Ophiopogon japonicus on the sun field, gently rub it with your hands after the moisture is dry, rub it again and again, repeatedly until the fibrous root is rubbed off. Then dry in the sun and use a sieve to remove impurities. If you encounter cloudy and rainy weather, you can bake it for 20 hours with a gentle fire of 40 ℃ and 50 Mel, take it out and put it for a few days, wait for the internal moisture to seep out, then dry until now, sift out the impurities, and become a commercial Ophiopogon japonicus. Generally, 150 kg of dried Ophiopogon japonicus is produced per 667 square meters, and the high yield can reach 250 kg.

Ophiopogon has been planted for a long time, from spring to summer every year, we can grasp this time period. Ophiopogon can usually be harvested after planting for a year. When harvesting, we should pay attention to the method, remember not to dig casually, and process it in time after harvest, so that its value can be created.
