Latest Cultivation Techniques and Methods Tutorial for Jiaogulan

Jiaogulan (Gynostemma pentaphyllum) is a herbaceous climbing plant of the Cucurbitaceae family, and it is widely cultivated in southern China. It is also very popular because Jiaogulan has effects such as reducing inflammation and detoxifying, relieving cough, and contains various vitamins. Moreover, Jiaogulan is also a very famous tea; Jiaogulan tea has the effect of lowering blood lipids and preventing and treating various cardiovascular diseases. So how should Jiaogulan be cultivated? Below, the editor brings you the cultivation techniques for Jiaogulan. Let's take a look together!

1. Land preparation and fertilization

Jiaogulan is a plant that likes warmth and dislikes water. It has strong adaptability and is relatively simple to grow, so it can grow on various soils. However, try as much as possible to choose shady soil with good drainage and irrigation and fertile texture. After choosing the land, plow deeply and harrow finely, loosen the soil, and make field beds to facilitate later management and harvesting. Then apply sufficient base fertilizer and disinfect the soil. The base fertilizer is mainly farmyard manure, then combined with an appropriate amount of lime. Pay attention to the fertilizer amount; farmyard manure is about 650kg/mu, and lime is about 25kg, ensuring that Jiaogulan has enough nutrients for growth.

2. Sowing and raising seedlings

After preparing the land, use fresh seeds to start sowing and raising seedlings. Pay attention to the appearance of the seeds. Jiaogulan seeds that are grayish-dark with spots indicate that the seeds are relatively mature and have strong germination ability; pick out the light-colored immature seeds. The germination rate of fresh seeds is very high, so when selecting seeds, we must pay attention to the freshness of the seeds. Seeds stored for 6 months basically cannot germinate. The sowing time is in spring and autumn each year; the temperatures in these two seasons are relatively warm, suitable for seed germination and seedling emergence. After sowing, pay attention to covering with fine soil to keep warm. Under normal management, seedlings can emerge in 8-12 days, and after the seedlings grow for about one and a half months, they can be transplanted and planted.

3. Water and fertilizer management

Although Jiaogulan's water demand is not large, the soil must still be kept moist. However, pay attention to the water amount, and absolutely no waterlogging should occur. If there is rainy weather, drain water in time, and spray pesticides in the field for pest and disease control. 5-7 days after successful planting, topdressing should begin, and later topdress in a timely manner according to the plant's growth condition. Jiaogulan's demand for nutrients is relatively large, so during the growth process we must ensure timely topdressing to prevent growth obstruction caused by malnutrition. But also pay attention to the fertilizer amount; excessive amounts may cause root burn in the plants.

4. Timely harvesting

Jiaogulan's harvest time is somewhat different from other crops. The best harvest time for Jiaogulan is before flowering and fruiting, when the plant is about 1-8 m. This is because before flowering, the nutrient content in the plant is the highest, and at this time the plant's color, aroma, taste, and quality are at their peak. However, it can only be harvested at this time. If harvested too early, Jiaogulan's quality is poor and its commercial value is low. But if harvested too late, the plant gradually ages and its value is even lower. When harvesting, pay attention to keeping the roots, because Jiaogulan is a regenerating plant; after keeping the roots, it can regenerate from the old stubble.

The above is a brief introduction to Jiaogulan cultivation techniques. Jiaogulan's market is very large, but this is mainly because Jiaogulan has high nutritional value and obvious effects. If you want to grow high-yield Jiaogulan, you must cultivate it step by step down-to-earth, with patience and careful management, in order to increase yield and ensure quality.
