When to plant sesame seeds?

The suitable sowing date of summer sesame is from late May to early June. The suitable sowing date of autumn sesame is early and middle July, and it can be later than late July under the condition of good heat. Sowing is a traditional sowing method in Jianghuai area, which is suitable for grabbing soil moisture and sowing. When sowing, seeds are spread evenly, covered with shallow soil and emerge quickly, but it is not conducive to field management.

Sesame seeds are small, and too much nitrogen fertilizer is often applied at the bottom, which makes the seedlings grow vigorously and form tall seedlings. Therefore, it is an important measure for sesame to grow early and grow healthily by combining early plant spacing with early planting and applying seedling fertilizer mainly with quick-acting fertilizer once early.

Sesame is often mixed with dwarf crops because of its erect stems and small shade area. For example, it is mixed or intercropped with sweet potatoes, peanuts, soybeans and other crops. Generally, a row of sesame seeds should be intercropped in the ditch between 65438 and 0-2 rows of sweet potatoes or every 2-4 rows of peanuts. Sesame is more drought-tolerant, while beans are more moisture-tolerant. Mixed cropping of sesame and beans is beneficial to prevent drought and flood disasters.

Both summer sesame seeds and autumn sesame seeds are sown in the season with high temperature and large evaporation. Precise soil preparation and water conservation are the keys to the whole seedling.

In the case of high soil moisture, the ground can be raked vertically and horizontally after ploughing, and raked horizontally after sowing to cover the seeds; In the case of low soil moisture, sow immediately after harrowing, harrow and cover seeds, and inhibit soil moisture retention. Sesame is afraid of waterlogging, and its growing period is in a rainstorm period. Therefore, when planting a single sesame, it is necessary to make a border ditch-about 2-3 meters wide, and level the border ditch, waist ditch and surrounding ditch to facilitate timely irrigation and drainage.
