How to apply fertilizer to high yield sesame seeds

Sesame is one of the main oil crops in China, and its application value is very high. And sesame is also used to make all kinds of dishes in our country, which is welcomed by many people. When planting sesame seeds, the higher the yield, the better. If you want to increase production, then fertilization is very important. So how to fertilize sesame seeds in order to achieve high yield? The following editor will give you a brief introduction, let's have a look!

1. Apply sufficient base fertilizer

When planting sesame, we should pay attention to apply sufficient base fertilizer at one time, which can enhance the growth ability of sesame root. Promote the growth of taproot, increase the number of lateral roots and promote nutrient absorption. Under the condition of sufficient base fertilizer, sesame seedlings can start early, expand their leaf area, provide sufficient organic matter for sesame growth and meet the nutrients needed for sesame growth. Usually, about 2500kg mature farm manure should be applied per mu, combined with appropriate amount of compound fertilizer. Among them, an appropriate amount of phosphorus and potassium fertilizer should be added to the base fertilizer to improve the oil content of sesame.

2. Topdressing seedling fertilizer

Sesame in the seedling stage, although the demand for fertilizer is not very great. However, if the sesame seedlings are thin and the growth is poor, then it is very important to fertilize reasonably according to the actual situation, in order to cultivate strong seedlings and promote flower and leaf differentiation. The fertilizer absorption capacity of sesame seedlings is relatively poor, so attention should be paid to the application of appropriate amount of nitrogen fertilizer when weeding in the middle tillage. To promote sesame seedlings to develop early, the best time to apply available fertilizer should be at the time of flower bud differentiation, urea about 4kg should be applied every time. Strip application and point application are the main fertilization methods to ensure its fertilizer effect.

3. Flower bud fertilizer

At the first flowering stage of sunflower, it is a suitable time to apply bud fertilizer. In the flower bud stage, the sunflower is mainly vegetative growth, reproductive growth and growth. Topdressing flower bud fertilizer can ensure the differentiation of flower buds at the top and provide sufficient growth nutrition for sesame. But also can prevent the phenomenon of premature senility of sesame. When topdressing flower bud fertilizer at budding stage, nitrogen fertilizer is usually the main fertilizer, and urea or ammonium sulfate can be applied. According to the investigation of professional data, the pure nitrogen of 1kg can increase the yield of sesame by about 4kg during this period.

4. Foliar fertilizer

The foliar fertilizer of sesame is also very important. In the sesame bud stage and early flowering stage, use borax solution to spray the page. Promote the germination of pollen and the growth of pollen tube, improve the pollination and fertilization rate, so as to increase the oil content. Then the second foliar topdressing was carried out at the sesame bud stage and early flowering stage. Fertilizers are mainly potassium dihydrogen phosphate and urea, or topdressing can be carried out at full bloom. It can effectively avoid premature senescence of sesame and improve the yield and quality of sesame.

The above is a brief introduction of how to fertilize sesame seeds to achieve high yield. That's all for today's introduction. This article is for reference only. I hope it can help you all.
