What are the precautions for planting sesame in summer?
What problems should be noted when planting sesame in summer? Please give an introduction because during the summer sesame sowing period, temperatures are high and the weather is changeable. If drought occurs, the seedlings are easily "scorched to death," causing gaps in the stand; if heavy rain occurs, they are easily "smothered to death," also causing gaps in the stand. Therefore, mechanized sowing is recommended, sowing 0.7 kg per 667 sq m, using 2...

What technical points should be paid attention to for high-yield sesame cultivation?
What should be paid attention to for high-yield sesame cultivation? Please introduce that for high-yield sesame cultivation, the following stages must be handled well: the intertillage and weeding stage. After thinning sesame seedlings, shallow hoeing should be done to loosen the soil and remove weeds. When the seedlings are 5 cm tall, carry out the second intertillage. After that, carry out 1-2 more intertillages according to soil conditions and seedling growth, so as to achieve loose soil and good aeration...

How to fertilize sesame for high yields? Detailed fertilization methods
How to fertilize sesame for high yields? Please provide guidance on the nutrient requirements of high-yielding sesame. Sesame is a fertilizer-loving crop; for every 100 kg of seed produced, it needs to absorb 8-9 kg of pure nitrogen, 3 kg of phosphorus pentoxide, and 7 kg of potassium oxide. At present, sesame yields are generally 40-60 kg per mu, while high-yielding fields generally reach 75-95 kg...

How to fertilize sesame for good results when planting it?
How should sesame be fertilized when planting? Please give guidance. For fertilizing sesame, you can refer to the following methods: Apply seedling fertilizer early. Because sesame seeds are relatively small, and because too much nitrogen fertilizer is often applied as a base fertilizer, the seedlings are prone to excessive vegetative growth and become leggy seedlings. Therefore, for sesame, in combination with early thinning and early final thinning of seedlings, apply a quick-acting fertilizer once early according to seedling condition. Applying seedling fertilizer well is an important measure for sesame to start growing early and grow vigorously. For seedling-stage fertilizer, diluted decomposed human manure or urea is preferable. Generally, after final thinning, apply 2-3 kg of urea per mu as a topdressing. When drought is severe, first relieve the drought and then apply the topdressing, or dilute it with thin human manure and pour it on. For those with weaker seedling vigor, the "special meal" method should also be used to apply a seedling-promoting fertilizer. When applying seedling fertilizer to sesame, also according to the characteristic that sesame has a relatively shallow root system, apply it as shallowly as possible or concentrate it near the roots.

How should micronutrient fertilizers be applied during sesame cultivation?
How should micronutrient fertilizers be applied when growing sesame? Please give guidance. The main trace elements needed during the growth and development of sesame include boron, zinc, manganese, iron and other elements, but the absorption amount differs at different growth stages. During the seedling stage, the absorption rate is slow and the accumulated amount is small; from the flowering stage to the topping stage, the absorption rate is fast and the accumulated amount is large; from topping to mat...
