How to manage black sesame in summer

How should black sesame be managed in summer? Please give guidance to the summer management methods of black sesame can refer to the following: first, determine the seedlings, check the seedlings to fill the gap. Because the sesame seeds are small and the number of seedlings is large, after emergence, the seedlings should be sparse when the first pair of true leaves grow, the seedlings should be fixed when growing to 2-3 pairs of true leaves, and the black sesame seeds are generally kept about 8000 seedlings per mu; if the soil moisture during sowing is poor and the seedlings are short of ridges, thinning or budding can be used to ensure that the whole seedlings are strong. Second, ploughing and weeding, cultivating soil and protecting the side. As the saying goes, "dry hoe millet wet hoe flowers, not dry wet hoe Zhi", after the seedlings should be shallow hoe loose soil to weed, when the seedling height is five centimeters, the second intermediate ploughing, and then ploughing 1-2 times; pay attention to hoeing can not hurt roots, seedlings grow to about 33 cm, should support soil bacon, anti-wind lodging. The third is topdressing fertilizer and topping moisture at flowering stage. Sesame needs more fertilizer at flowering stage, so it should be fertilized with 10-12.5 kg urea per mu at early flowering stage, 120-150 grams of potassium dihydrogen phosphate or active humic acid and foliar fertilizer mixed with water at full flowering stage for extra-root topdressing; in the capping period, the top of the plant should be removed by hand on a sunny day, and the appropriate coring length should be 2 cm; fourth, chemical control to promote yield. After the full flowering stage, 40-50 grams of paclobutrazol mixed with water 25-30 kg uniform foliar spray, less spraying of poor growth, proper amount of spraying and early spraying of good growth can increase production by 8-10%.
