Latest Planting Time and Key Management Techniques for Spring Sesame
Sesame is a major oilseed crop in China, and there is a huge demand for sesame oil in China. Moreover, sesame has very high nutritional value; it can not only be used for pressing oil, but also for making various dishes and pastries. It is welcomed by many people. When planting sesame, spring sesame is generally the main type. So when should spring sesame be planted? And how should it be managed? Below, let's take a look together with the editor at the planting time and management of spring sesame!
1. Land preparation and fertilization
Before sowing sesame, we must first pay attention to doing a good job of land preparation, breaking the soil up finely and leveling it, then raising ridges and making beds. Keep the ridge height at about 10cm, and control the plant and row spacing at about 10*40cm. In addition, the planting plot must have good drainage and irrigation; when there is too much water, it can drain promptly, and when there is drought, it can also replenish water promptly. Then apply sufficient base fertilizer to provide ample nutrition for the growth of spring sesame. During land preparation, apply various fertilizers such as farmyard manure, superphosphate, and urea together. Alternatively, farmyard manure can be replaced with compound fertilizer.
2. Planting time
The sowing time of spring sesame is very critical. Generally, it can be planted only after the temperature gradually rises. Usually, May each year is the best sowing time for spring sesame. The sowing methods for sesame include drilling and broadcasting. After sowing, the soil covering should not be too deep, so as to keep the emergence time of sesame uniform. After sowing the sesame seeds, do a good job of weed control, preferably mainly by manual weeding. Also do a good job of pressing to preserve soil moisture, ensuring the seedling emergence rate after sowing spring sesame, and then do a good job of management after the seedlings emerge.
3. Thinning and replanting
During the seedling stage of sesame, we need to do a good job of management. Generally, when sesame seedlings grow about 2 true leaves, begin the first thinning. Then when 4-6 true leaves have grown, thin again. Thinning should mainly remove the weak and keep the strong, providing sufficient growth space for strong seedlings. Finally, we should also check the growth of the seedlings. When missing seedlings are found, promptly replant with strong seedlings of the same growth. Transplant at the appropriate time when there are about 7 true leaves. After transplanting the seedlings, water them well to settle the roots.
4. Topping and disease prevention
Generally, around the Mid-Autumn Festival, we should do a good job of topping, pinching off about 1.5 cm from the top of the sesame plant. This inhibits the growth advantage of the top and avoids consuming too much nutrition. It can also concentrate nutrition in the seeds, increase the thousand-grain weight and yield of sesame, and enhance quality. Then we should also do a good job of preventing and controlling common sesame diseases and pests such as fusarium wilt, phytophthora blight, and cutworms. When abnormalities are found, check promptly, identify the specific cause, and then take corresponding measures to ensure the normal growth of sesame.
The above is a brief introduction to the planting time and management of spring sesame. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
