1 fine tuning. The sulcus width is 33cm, the height is 20cm, and the width is 1 to 1.2m. The width is suitable for management.
2 timely sowing. Digging shallow ditch in the surface, the ditch (also line spacing) 33 cm, when sowing, because of the small seeds of sesame seeds, the density is difficult to control, can be mixed with a small amount of dry fine soil, and then sown.
3 Chemical Weeding After 3 days of sowing, 60% Kou Naisi EC is used in 60 mus, 50 kg of water is diluted and evenly sprayed on the surface of the lotus root, which can reduce the growth of weeds.
4 seedlings. After more than 10 days, grow 2 to 3 cotyledons after the emergence of seedlings, 5 to 6 days and then again, so that the spacing between the 22 to 24 cm, acres planting 8000 to 10000 strains. Suitable plant spacing favors its branching.
5 Scientific fertilization. One should apply basal fertilizer, applying 1500kg of fertilizer per acre. After growing 3 to 4 true leaves, applying 1 to 2 times of human excreta, flowering and podling period is the most vigorous growth period of sesame, and it is also the period of peak fertilizer demand, applying ammonium sulfate 10~15kg per mu and using 0.4% of the Potassium dihydrogen phosphate and 0.2% borax mixed solution were sprayed on the foliage, sprayed once every 5 to 7 days, and sprayed twice.
6 Prevention and control of pests The main diseases of sesame are blight, anthracnose, etc.; insect pests include aphids and green-blind stink bugs. Sesamia blight mainly damages seedlings and young roots. Sesame anthracnose can occur from emergence to maturity, and can be sprayed with 50% carbendazim WP 500 times. This year, locusts and green-blind stink bugs are heavier. They are sprayed with 40% acetophos EC 1,000 to 2,000 times. They are penetrated up and down. When the pests begin in early June, they are sprayed 2-3 times every 7 to 10 days. .
7 Timely topping
After the full fruit period, when the top leaf segments of the main stem are clustered and almost stop growing, the top buds are picked on a clear sunny morning.
8 timely harvest. The yellow sesame seeds are ripe and the black seeds can be harvested.
