How to fertilize the latest sesame to get high yield

Sesame is one of the main oil crops in China, and its application value is very high. Sesame seeds are also used to make various dishes in China, which are welcomed by many people. When planting sesame seeds, the higher the yield, the better. Fertilization is important if you want to increase yields. So how can sesame be fertilized to produce high yields? The following small series will briefly introduce you, let's take a look together!

1. Apply sufficient base fertilizer

When planting sesame seeds, pay attention to applying sufficient base fertilizer at one time. Sufficient base fertilizer can enhance the growth ability of sesame roots. Promote the growth of taproot, increase the number of lateral roots, promote nutrient absorption. Under the condition of sufficient base fertilizer, sesame seedlings can sprout early, expand their leaf area, provide sufficient organic matter for sesame growth, and meet the nutrients required for sesame growth. Usually, about 2500kg of decomposed farm manure should be applied per mu, with appropriate compound fertilizer. The oil content of sesame seeds can be increased by adding proper amount of phosphorus and potassium fertilizer to the base fertilizer.

2. Topdressing seedling fertilizer

Sesame seeds at seedling stage, although the need for fertilizer is not very large. However, if sesame seedlings are thin and grow poorly, it is very important to apply fertilizer reasonably according to the actual situation, and to cultivate strong seedlings and promote flower differentiation. Sesame seedlings fertilizer absorption capacity is relatively poor, so in the time of intertillage weeding, pay attention to the right amount of nitrogen fertilizer. The best time to apply quick-acting fertilizer should be when flower bud differentiation occurs, and about 4kg urea should be applied every time. The fertilizer application method should be strip application and spot application to ensure its fertilizer efficiency.

3. Flower bud fertilizer

At the beginning of sunflower flowering, it is the appropriate time to apply bud fertilizer. At the bud stage, sunflower mainly grows vegetative, reproductive and long. Topdressing fertilizer can ensure flower bud differentiation at the top and provide sufficient nutrition for sesame growth. but also can prevent premature senescence of sesame seeds. When applying bud fertilizer at budding stage, nitrogen fertilizer is usually the main fertilizer, urea or ammonium sulfate can be applied. According to professional data surveys, 1kg of pure nitrogen can increase sesame yield by about 4 kg at this stage.

4. Foliar fertilizer

Sesame foliar fertilizer is also very important. At the time of bud stage and early flowering stage of sesame seeds, borax solution should be used to spray the leaves. Promote pollen germination and pollen tube growth, improve its pollination fertilization rate, thereby increasing the oil content. Then, the second foliar topdressing is carried out at the time of sesame bud stage and initial flowering stage. The fertilizer is mainly potassium dihydrogen phosphate, urea, etc., or topdressing can be carried out in full bloom. can effectively avoid premature senescence of sesame seeds and improve the yield and quality of sesame seeds.

The above is a simple introduction to how sesame can be fertilized to produce high yields. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
