How to cultivate black sesame with high yield?

How to cultivate black sesame with high yield? Please guide black sesame cultivation methods can refer to the following planting methods: first, soil preparation and fertilization to select high-lying, well-drained fields, intensive cultivation, combined with soil preparation, apply sufficient basic fertilizer: 10 kg of urea and 50 kg of phosphorus and potassium fertilizer per 667 square meters. Flatten and rake it to pieces and wait for sowing. Second, sowing black sesame has spring sowing and summer sowing. Spring sowing before and after Grain Rain, summer sowing before and after Grain in Beard, mainly wheat stubble and rape stubble. When sowing, sow the black sesame seeds evenly on the finished border. The sowing rate is 1 kilogram per mu. Third, after the field management of black sesame seedlings, attention should be paid to ploughing and weeding. The "double-stem cultivation method" is mainly used in seedling stage management. That is, when the third pair of true leaves of sesame seedlings are semi-unfolded, the tip is removed, and the first (or second) axillary buds germinate and grow to form double stems. The following points should be mastered when using this method. 1. Seed dressing with medicine, crop rotation and early sowing. Before sowing, use 50% carbendazim wettable powder or 40% carbendazim gel suspension 8 grams, add 0.5 kg of water into a paste, mix well with 0.5 kg seeds to be sown. Black sesame seeds avoid continuous cropping and advocate the system of two heads for four years. Try to grab the stubble and sow early. two。 Sowing early at the right time to master the density. The sowing date of summer sesame is no later than June 15, generally the earlier the better. The planting density is generally 667 square meters, 8000 trees, and 10000 plants. 3. Strictly control the time and method of topping, summer sesame leaves retain 2 pairs of real leaves topping, and retain the leaf above 2 Mel 3 cm stem nodes. In the same field, the standard of keeping true leaves is the same, and the top is finished at one time. 4. Pay attention to topdressing seedling fertilizer: after topping sesame, in order to prevent the phenomenon of de-fertilization of new branches, an appropriate amount of quick-acting fertilizer can be applied: when the new branches grow the second and third pairs of true leaves, 100 times of liquid metoprolol or paclobutrazol should be sprayed to prevent later inversion and increase the number of effective capsules. 5. Prevent stains, resist drought, manage early in the morning and prevent grass famine. When planting, first open a good border ditch and perimeter ditch, generally border surface width 2Mel 2.5 meters, border ditch depth 0.3 meters. The depth of the trench is 0.4 mi 0.5 m. The seedlings were fixed when there were 3 pairs of true leaves, the row spacing was 36 cm × 12 ~ 15 cm, and the weeding was done once. When the seedling height is 33 cm, topdressing is used to cultivate the soil. 6. Scientific fertilization and prevention of diseases and insect pests, summer sesame growth time is short, need more fertilizer and concentrated, should apply more base fertilizer. About 10 kg of urea, 30 kg of phosphate fertilizer and 10 kg of potash fertilizer are applied every 667 square meters. During the growing period, 5kg of urea can be applied every 667 square meters to the fields where the seedlings are thin and weak. The jointing stage can be used to prevent horn blight and leaf blight. 1000 times of hydantoin can be used to spray leaves twice. If aphids occur, you can use 2000ml 3000 omethoate EC spray. Fourth, harvesting and processing black sesame seeds are generally harvested after the aboveground stems and leaves are mature after autumn, and the black sesame seeds are cut off and bundled into small bundles. After drying, the black sesame seeds are threshed and dried to clean the impurities, which are sold as commodities.
