The author lives in the countryside and has planted sweet potatoes for more than 20 years. For the sweet potato to turn over the vines, my experience is: whether sweet potatoes are grown or not depends on the growth. First, the soil with high fertility must turn over. For soil blocks with high fertility, sweet potato vines thrive due to adequate nutrients. Especially in rainy years, a large number of nutrients are caused by the growth of the vine through the lumbar roots. At this time, if you do not pass the vine, reduce the supply of nutrients, and suppress the growth of sweet potato vines, the yield of sweet potatoes is absolutely low. In the words of some farmers, there are only vines and no potatoes. Second, the poor soil can not turn over. The newly-opened clods, especially the loess in the mountainous areas, cannot be turned over. Because sweet potato vines grown on this soil are mostly slow growing, there is almost no lumbar root. Turning the vines at this time will affect the photosynthesis of sweet potatoes, which will cause new branches, consume large amounts of nutrients, and affect the expansion of the tubers, which will reduce the output of sweet potatoes. Third, lumbar root can not increase the yield of sweet potato. The author has done experiments to allow the growth of sweet potatoes, that is, to make the whole sweet potato vine without soil and crawl on the bamboo arch. As a result, the output of sweet potatoes is increased by about 30% compared with that without arches. This shows that the lumbar root does not improve the yield of sweet potatoes. Fourth, the nature of fertilizers affect the growth of sweet potatoes. Sweet potatoes of the same variety will have different yields if the nature of the fertilizer is different. Sweet potatoes are potash-retaining chlorine plants. The soil contains more potassium. The sweet potato's tubers swell quickly and their yield increases. If you just use nitrogen fertilizer blindly, sweet potato vines will grow wild. At this point, no matter if you are turning a rattle or not, you can't increase the yield of sweet potatoes. Fifth, we must use the "marginal" role as much as possible. Planted sweet potatoes should not be "plate planting", that is, the clods into a very wide one-sided. Sweet potatoes grown in this way not only reduce the photosynthesis of the leaves, but also increase the humidity of the soil (sweet potato avoids water). In this case, whether you turn the basket or not, you can't increase sweet potato yield. Therefore, when planting sweet potatoes, it is advisable that the soil blocks should be sorted into 50 cm one-box compartments, and each side should be planted with a single pot of sweet potatoes. The margins of the soil trenches should be fully utilized to improve the photosynthesis of sweet potato vines and promote the expansion of the potato vines.

A standardized herbal extract is an herb extract that has one or more components present in a specific, guaranteed amount, usually expressed as a percentage. The intention behind the standardization of herbs is to guarantee that the consumer is getting a product in which the chemistry is consistent from batch to batch. This practice has developed out of the drug model of herbal medicine, in which modern scientists have attempted to identify the components of a plant that have definite pharmacological activity in the body. Unfortunately, while scientists can isolate many constituents from an herb and discover how particular chemicals may act in the body, they inadvertently remove or overlook components that may contribute to the activity of the whole herb. Consequently, standardization may concentrate one constituent at the expense of other potentially important ones, while changing the natural balance of the herb`s components.
