How to increase the output of sesame

Sesame is a commonly used ingredient in our life, but its use is not only as a food, but also as feed, fertilizer, vegetable oil and so on. The nutritional value of sesame is quite high, the economic value in the market is also very good, and the demand is also relatively large, but very often the output of sesame is not high. Then the editor will introduce to you how to improve the output of sesame.

1. Land preparation and seed selection

Sesame does not require much land for planting, and the land that often grows sesame will become more fertile, but when preparing the soil, we should pay attention to loosening the soil, leveling the land, getting rid of weeds, and then digging ridges and opening drains. This can control the moisture needed during the growth of sesame. When selecting seeds, it is necessary to choose good varieties, that is to say, the seeds with strong ability, strong resistance and high yield should be selected. Good varieties are the most basic requirements for high yield.

2. Sowing method

There are generally two ways of sowing sesame seeds, the first is double-layer sowing, that is, a piece of land is first sown with a layer of seeds and then covered with soil, followed by a second layer of seeds. One advantage of this method is that when the weather is relatively dry, the seeds in the first layer can absorb water from the ground to germinate and grow seedlings, while the seeds in the second layer can fully grow seedlings when it rains. When the seedlings grow to five or six centimeters, they can be transplanted. The second way is to sow seeds directly between heaven and earth according to a certain interval, but then there will be the phenomenon of seedlings, so it is necessary to replenish seedlings in time.

3. Field management

Field management is to carry out fertilization, weeding and some daily trifles, but it is a big deal for sesame, and if it is not properly handled, it will be a serious reduction in yield. The first fertilization is after transplanting or when the seedlings grow to five to ten centimeters, this is for the growth of seedlings, and the second fertilization is when flowering, and the most nutrients are needed at this time, so be sure to replenish the nutrients in the soil in time. At this time, the soil nitrogen fertilizer is combined with spraying phosphorus, potassium and boron outside the root. Potassium dihydrogen phosphate should be applied about a week after flowering. When the main stem grows to a certain height, the terminal bud should be removed, because it needs the most nutrients, so it should be removed in time in order to reduce unnecessary nutrient consumption.

4. Disease prevention

Sesame is prone to leaf blight and small land tiger, so we should carry out timely treatment. Leaf blight will cause the whole plant to wither and die, with serious consequences, and small land tigers love to eat sesame, so in order to ensure production, it is better to get rid of it as soon as possible.

5. Timely harvest

The harvest of sesame is more critical, if the harvest is too late, the capsule of sesame has been cracked, then the sesame will all fall to the ground, when you harvest, there is basically little left, and at the same time, it can not be harvested too early. Sesame is not yet ripe at that time, so the most suitable time for harvest is to wait until most of the two leaves of sesame turn yellow and fall off, and the bottom capsule can be harvested slightly.
