Sesame is known as "the crown of the eight valley" and is an all-powerful crop of oil, spices and medicine. However, to achieve high yields, it is necessary to precisely control the timing of cultivation and key technologies. In the light of the experience of the old farmers in henan and hubei, the author has drawn up a scientific planting programme to help you grow good-quality sesame seeds
I. Optimal planting time (north-south differences to be noted)
1. Young river basin (henan, anhui): seeding at 18°c in mid-may-early june
2. Yangtze river basin (huipe, hunan): in early may and late may, a barrage of rice rain was planted
3. North-east: in mid-june, the selection of pre-cooked varieties was required to prevent frost
4. South china: spring (march) and autumn (august) seasons
Key tips: seeding of premature, perishable species, late exposure to drought and reduced production, it is recommended to measure 5 cm of soil temperature by thermometer。
Ii. A full process of high-yield cultivation (7-step operation)
1. Land selection
Symptoms: rotations with an interval of more than three years
Gradient: slope < 5°, drained block
25 cm deep ploughing: 2000kg manure per acre fertilated manure + 30kg calcium phosphate
Seed treatment
Sunshine: choosing the sun for two days, killing the fungus
Selection: salt water (1. 08 per cent) drifts away from the granules
Clothes: 0. 3 per cent of seeds mixed with more than 50 per cent fungus plant
Scientific seeding
Radio: 40 cm line, = 0. 4-0. 5 kg per acre
Caves: 20 cm range, 4-5 grains per lavender (2 remaining)
Depth: clay 1. 5 cm and sand 3 cm
4. Field management
Interstellar seedling planting: seedlings during three leaves and seedlings during five leaves (12 million acre)
Weeding in chinese: first tilling at 10 cm height, 3 times before the current rhesus
Precision fertilization: urea 5kg + potassium sulphate 8kg
High-strength: 3 cm at the top during the flowering season, more than 15 per cent
5. Pest management
Paradoxin: 30% of frosted rote is ploughed at 800 times the root
Aphids: yellow viscos + 10% aphids 2000 times spray
Inverted: 0. 2 per cent potassium phosphate sprayed during the current period
Iii. Harvesting and storage (critical in determining oil content)
- the next leaf is falling off with the tan
Harvesting techniques: morning dew harvest, laced in 20 cm in diameter
-scattered grafts: 7 days after drying, the seed < 9% > library
In particular, sesame sensitivity to herbicides, caution in the use of ammonium-type agents such as ethylachlor, and the use of black membranes for herb control are recommended.
