Sweet potato leaves grow crazy, but there is no sweet potato in the soil. Where are the sweet potato chips?
Generally speaking, sweet potatoes will not gradually expand their roots until the Beginning of Autumn. It is quite normal to say that sweet potatoes grow vines without red potato lumps at present. Generally speaking, sweet potatoes are conducive to root mass expansion when the light time is about 13 hours. At this time, it is also basically entering the the Beginning of Autumn season.
Some netizens also mentioned a variety of Taiwan sweet potato, which belongs to the type of ivy that does not grow, but the planting area of this kind of sweet potato in our country is still very small. Let's focus on the relationship between fertilization and long pieces. This is also a big problem in the current growth.
Generally speaking, an ivy is a long leaf. Yesterday, I also gave a general answer to the fertilizer corresponding to the root, stem, leaf and fruit. " Nitrogen promotes leaves, phosphorus promotes flowers, and potassium promotes fruit ", basically.
The ivy that appears in the growth of sweet potatoes is the phenomenon of excessive growth of leaves. In view of this situation, all we need to do is to control the amount of nitrogen fertilizer. To promote the expansion of potato nuggets, you need to supplement potash fertilizer! We all know that sweet potato is the part of starch accumulation, in which potassium is the key factor to promote starch synthesis.
If the proportion of nitrogen fertilizer and potash fertilizer in the field is not appropriate when entering the Beginning of Autumn, it will inevitably lead to long vines without expanding potato lumps. Adjusting the fertilizer ratio is a good way, such as plant ash in rural homes, as well as potash are optional objects, such as potassium dihydrogen phosphate can also choose foliar spraying, and the effect is quick.
In fact, the best choice is to spread organic fertilizer, but now the popularity of chemical fertilizer leads to farmers often ignore or even do not pay attention to it. The effect of organic fertilizer is comprehensive and more lasting, which can greatly improve the quality of sweet potato. In addition, if the sweet potato is strong and prosperous, it can also be inhibited by growth regulators, such as paclobutrazol.
