The Latest Cultivation Techniques and Methods Tutorial for Galangal

Galangal is a traditional Chinese medicinal herb in China. Galangal has a certain antibacterial effect, can inhibit coagulation, and has an analgesic effect, so it is mainly used for pain relief. Moreover, galangal is also a very good seasoning and is very popular in China. It is mainly distributed in the Guangdong and Guangxi regions, but due to the nutritional value of galangal, a certain planting area has also been established in China. So how should galangal be planted? Below, the editor brings you the cultivation techniques for galangal. Let's take a look together!

1. Land preparation and fertilization

Galangal is not suitable for growing in water-deficient and arid, low-lying, uneven and heavily clayey soil, nor is it suitable for continuous cropping. Therefore, we first need to choose a sufficiently soft, highly permeable and fertile sandy soil for planting. Then in winter and spring, plow the land deeply by about 28 cm, and then apply sufficient base fertilizer. The base fertilizer is mainly decomposed farmyard manure, with the amount controlled at about 3000 kg/mu. Then hoe shallowly to fully mix the fertilizer with the soil. The depth of the base fertilizer should not exceed 20 cm to prevent the fertilizer from losing its effect, and then make beds ready for planting.

2. Timely sowing

The seed collection time for galangal is generally around late autumn each year. Seeds should be plump, free of pests and diseases, and without wounds to ensure seed germination capacity. In addition, galangal seeds do not store well, so it is best to sow them as soon as they are collected. Before sowing, soak the seeds to promote germination and disinfect them. Then prepare a seedling bed. The preparation method is similar to that for the field, with the row spacing controlled at about 10 cm for furrow sowing. Then evenly scatter the seeds into the sowing furrows. After sowing, cover with soil and grass. Under normal management, they will germinate after about 3 weeks, and then transplant at the appropriate time according to the growth of the seedlings.

3. Intertillage and weeding

After the seedlings successfully emerge fully, weeding needs to be carried out about every 3 weeks, because galangal seedlings have limited growth capacity and weak nutrient absorption, so weeds must be prevented from competing for the nutrients needed for galangal growth. When weeding, pay attention to the force used to avoid damaging the seedling roots, affecting root nutrient absorption and hindering the growth of galangal. Then in winter, when the aboveground part of galangal gradually withers, cut off the withered parts about 6 cm above the ground. Then earth up about 4 cm to cover the buds and prevent galangal from being threatened by freezing damage.

4. Water and fertilizer management

Galangal does not have a high demand for water, but watering should still be reasonable according to soil moisture and changes in the rainy season. Pay attention to the amount of watering to prevent excessive water from causing root rot in galangal and triggering diseases such as root rot that affect the growth of galangal. During the growing period, galangal has a relatively large demand for nutrients, so topdressing is needed once after each weeding. Before winter, sufficient overwintering fertilizer should be applied together with the earthing-up work to enhance the plant's cold resistance and prevent freezing damage. Then after the beginning of spring, apply dilute manure water as topdressing to restore the vitality of the seedlings. Finally, before the rows close, mix plant ash with superphosphate and apply it at the base of the plants to promote the expansion of galangal roots. As the growing years of galangal increase, the frequency and amount of topdressing can be gradually reduced.

The above is a brief introduction to galangal cultivation techniques. Among them, it should also be noted that after the seedlings wither in winter, the soil covering the furrows should be made deeper to prevent rhizome rot. Then around April of the following year, clean up once again to prevent rainwater accumulation in the rainy season from affecting the growth of galangal. That is all for today's introduction.
