A Detailed Guide to the Latest Cultivation Methods for Millettia speciosa

Millettia speciosa is a traditional Chinese medicinal herb with powerful medicinal effects. Due to relatively large market demand, but wild resources are on the verge of exhaustion, artificial cultivation has risen and expanded rapidly within a few years. Many people have achieved prosperity by cultivating it, so more and more people are attracted to it. So how should Millettia speciosa be cultivated? Let's learn about it together.

1. Site selection and land preparation

Millettia speciosa is a deep-rooted plant with strict soil requirements. It is suitable for sandy loam soil with deep soil layers, loose texture and good drainage, so when deciding to plant it, you should observe whether the local soil conditions are suitable for the growth of Millettia speciosa. After selecting the plot, when deep plowing it, apply more than 5000 kg of decomposed farmyard manure and 50 kg of ammonium bicarbonate per mu, then harrow finely and level it, and then open furrows and form ridges. The ridges are required to be 40--50 cm wide and about 25 cm high. To prevent the ridges from collapsing on rainy days, use tools to pat both sides firm.

2. Sowing

The seed propagation method is used for cultivating Millettia speciosa. Collect the pods when they mature, take out the seeds after drying, and select plump, mature, undamaged and disease-free seeds for sowing. Before sowing, soak the seeds in warm water at 40-50 degrees for several hours, then place them in an environment at 40 degrees and 85% humidity for germination. When the seeds sprout, they can be sown. When sowing, seeds can be mixed with chemicals for sterilization to reduce the threat of disease. Open furrows on top of the ridges and sow, with a plant spacing of 3-5 cm. After sowing, cover with 3 cm of soil, using about 200 grams of seed per mu.

3. Seedling stage management

When the seedlings grow to 1-2 true leaves and when they grow to 2-3 true leaves, thinning should be carried out once each time to increase ventilation and light transmission for the seedlings so that they can emerge uniformly. After that comes final thinning. During final thinning, the seedling spacing should be controlled at 7-10 cm, and weak seedlings, diseased and dead seedlings, as well as overly vigorous seedlings should be removed, leaving seedlings of uniform size for final thinning, which makes management easier. The final thinning spacing determines the time to market. If you want to market earlier, the spacing can be left larger, while if you want to market later, the spacing can be denser.

4. Field management

Millettia speciosa grows slowly. During the seedling stage there are many weeds, which affect its absorption of nutrients and make growth even slower, so intertillage and weeding should be carried out reasonably according to field conditions and seedling growth. In addition, topdressing should be done 3 times during the growing period. The first time is when the plants grow to more than 30 cm, applying 10 kg of urea per mu; the second time is during the peak growing season, applying 8 kg of urea per mu, which can be combined with watering so that the fertilizer can be absorbed as quickly as possible; the third time is when the fleshy roots expand, when phosphorus and potassium fertilizers should be applied to increase yield, applying 10 kg of diammonium phosphate and 5 kg of potassium sulfate per mu.
