Sesame is a good oil crop. Sesame oil is fragrant and nutritious, and it also has certain health care functions. Therefore, in recent years, the demand for sesame has increased, and the area for planting sesame has expanded. When planting sesame seeds, there is a problem that must be particularly noticed, that is, it cannot be linked. That is to say, the land of sesame seeds has been planted in the previous year and cannot be planted in the second year. Otherwise, high yields and high benefits will not be achieved. Why can't sesame grow in the same way?

Sesame can not be planted
There are two main reasons: First, the cultivation of sesame seeds will increase the disease. In the process of sesame production, many pathogenic pathogens such as stem blight, bacterial wilt, and blight are all over the winter after sesame harvest. If sesame seeds are planted in the second year, these pathogens will become a source of infection for heavy sesame seeds. If the time is heavy, the more pathogens in the soil will be, and the disease of sesame will become more and more serious. Infected by diseases, sesame plants may develop dysplasia, short stigma and other diseases, and even severe wilting and death may occur. Second, sesame seeds are crops that require more fertilizer, and even planting can lead to nutrient imbalance. According to the test, for every 50 kilograms of sesame produced, it is necessary to absorb 4.50-5 kg ​​of nitrogen, 1.25 kg of phosphorus pentoxide, 5-5.50 kg of potassium oxide, and a ratio of three elements of about 4:1:4.40. It can be seen that sesame requires more nitrogen and potassium, and less phosphorus is needed. If the flail is planted, it will break the balance of soil fertility, resulting in a lack of nitrogen and potassium, and it is difficult to increase the yield of sesame. Therefore, sesame seedling cultivation is unscientific and should be avoided.
