Cultivation techniques of Fructus psoraleae

Psoralea corylifolia, also known as Fructus psoraleae, broken old paper, etc., is an annual herb of Leguminosae. Psoralea corylifolia must be very familiar to many people, among which psoralen tincture is made from psoralen. Fructus psoraleae is a kind of traditional Chinese medicine, which is used as a fruit, which has the effects of tonifying kidney and strengthening yang, tonifying spleen and stomach. So how to plant psoralen? The following editor brings you the cultivation techniques of Psoralea corylifolia. Let's have a look!

1. Land selection and preparation

Psoralea corylifolia likes to grow in dry, sunny places, so when choosing a planting site, you should make sure that it is planted in places with sufficient light, dry terrain and good drainage and irrigation. After selecting a good site, it is necessary to do a good job in soil preparation and reduce deep ploughing and turning the land at a depth of about 30 centimeters. After leveling and fine ploughing, the soil moisture should be opened up and ready for planting. Pay attention to control the high specification of the length and width of the border, and it is best to make it into the shape of the tortoise back, which is not only conducive to the growth of Psoralea corylifolia, but also conducive to the planting management of psoralen.

2. Soaking seeds to raise seedlings

Before sowing, the seeds should be soaked in gibberellin and other solutions for about 14 hours, which can effectively reduce the phenomenon of psoralen falling flowers and fruits, increase the fruit setting rate and increase the yield. Then soak the seeds in cold water for about 2-3 days to make the seeds fully like water, and then remove them and air-dry them. Then sow seeds before and after Ching Ming Festival, mainly strip sowing, control the row spacing at about 45 cm, and cover about 4 cm of soil after sowing. Then pour enough water and cover the soil with plastic film to improve the moisturizing capacity of the soil. under normal management, seedlings can emerge in about a week.

3. Timely transplanting

The sowing management should be done well after sowing, and the soil should be kept moist before emergence. When the seedlings grow out, the interseedling work should be carried out around May, and the plant spacing should not exceed 2 seedlings per 18 cm. In the middle of the seedling, we should pay attention to the principle of keeping the strong and getting weak, so as to ensure the whole seedling. Just said that after sowing, seedlings will emerge in the next week or so under normal management, and then strengthen seedling management, and transplant will be carried out after about a month. When transplanting, it is necessary to control the row spacing of planting plants to prevent planting from being too dense, and block each other in the middle and later stages, affecting growth.

4. Field management

After transplanting, when the seedlings survive, we should pay attention to the work of weeding in the middle tillage, keep the soil soft enough, the ability of drainage and irrigation is normal and free of weeds. Especially after the heavy rain, otherwise and stagnant water leads to rotting roots of psoralen seedlings, causing diseases and insect pests and so on. However, we should also pay attention to keeping the soil moist, topdressing more than twice in the planting process, and the fertilizer is mainly rotten farm manure to meet the nutrients needed for the growth of psoralen. Finally, it is necessary to do a good job in the prevention and control of diseases and insect pests, avoid unnecessary loss of psoralen, and enhance the growth of psoralen.

The above is a brief introduction to the cultivation technology of Psoralea corylifolia. The growth ability of Psoralea corylifolia is relatively strong, and it is relatively simple to plant, but it needs everyone's planting management work to ensure the growth of Psoralea corylifolia and increase the yield. That's all for today's introduction. This article is for reference only. I hope it can help you all.
