"The potato planted in the awn weighs ten kilograms, and the potato planted in the summer solstice is bare." How to grow sweet potatoes with the highest yield?

It is best to solve the soil problem before planting sweet potatoes to avoid insect eyes and cracking. Moreover, everyone should choose plots with fertile soil, loose soil, strong air permeability and standard irrigation and drainage pipes to plant sweet potatoes, which is the premise of increasing production. The sweet potato produced by this plot is much smoother, not easy to crack, and has more water and less chemical fiber, which is delicious. The biggest fear of planting sweet potatoes flat is the continuous high temperature weather. Therefore, everyone can't plant them from summer to the future. Even if it can be planted, it looks small and the yield is relatively low.

Because of the lack of water after planting sweet potatoes at high temperature, it is not conducive to slow root growth, poor drought resistance of long roots, and wilting will occur, because the seedlings have poor drought resistance after planting. In addition, in addition to planting sweet potatoes after moderate watering. There is also proper fertilization. Because, after selecting the flat planting method, all nodes will bear potatoes, and the amount of potatoes will increase. If the fertilizer efficiency is insufficient at this time, it will also lead to insufficient nutrition. Of course, the potato pieces grow slowly and the yield is low. Therefore, it is necessary to apply some chemical fertilizers appropriately. Sweet potatoes are uncontrolled, grow brightly, and the seedlings bear small potatoes, with low yield. Therefore, it is necessary to control the vigorous growth of sweet potato when it grows to 60-70 cm.

Because the land is small, we can control prosperity by raising or turning it over. Many large households in Zhanjiang City, Guangdong Province are thousands of acres of land, which is obviously too time-consuming and laborious. Therefore, it is necessary to use some growth control agents to control the growth. For example, uniconazole, chlormequat chloride or methylphenidate are all acceptable. When the sweet potato grows to 80-90 cm, it needs to be controlled again. As long as the sweet potato is applied with sole fertilizer at one time, the yield will be high and the drainage pipe does not need to store water. As long as the sweet potato seedlings planted in spring are not affected by the frost in early spring, the faster they are planted, the greater the yield. Because they are all cold dew, the early production time is long, which can develop strong roots and improve cassava starch. The suitable soil temperature for sweet potato tuber growth is 22-23℃.

Sweet potato with awn seeds developed for more than 60 days through the trend of rhizome development. In other words, through the solar terms of little summer, little summer, little summer and cold dew, the roots basically formed, reaching the peak of leaf and stem growth and development. Through the growth and development of roots and rhizomes of Pengdahe River in big summer, cold dew and beginning of autumn solar terms, the roots entered the period of rapid fruit expansion from winter to Sunday. Imagine planting sweet potatoes again in summer. According to the growth period of sweet potatoes, it will take first frost to enter the period of rapid fruit expansion. In first frost season, it is already the sweet potato picking period in the northern region, and the best quick harvest period has been missed. Sweet potatoes only constitute roots, and the yield is naturally extremely low.
