How to make high yield sesame

1. Select high-yielding varieties

"Zhongzhi No.7", "Chuangzhi No.1", "6304-1-5", "24103", "Xiongzhi No.1", "Capsule No.2" and other new varieties can produce more than 100 kg per mu. .

2. Timely sowing and reasonable density

Local table 5 centimeters deep ground temperature above 18 °C to sowing, to wait for the rain after the clear sowing. The sowing rate per acre is about 500 grams, and the depth is about 3 centimeters. After emergence, weeds should be shallow, deep, and shallow for three times. When the seedlings appear two or three pairs of true leaves, they will be seedlings, generally no less than 10,000 plants per acre.

3. Apply base fertilizer and scientific fertilizer

The sesame seeds should be scientifically fertilized, and the farmyard manure should be used as the basic fertilizer, which can be supplemented with calcium phosphate, urea, and potash fertilizers. Special attention must be paid to the flowering period, and the fertilizer must be applied in a timely manner. This is the key period for absorbing nutrients, generally 10-15 percent of the nitrogen fertilizer per acre. Kilograms; spraying potassium dihydrogen phosphate and boron fertilizer at full flowering stage to ensure full grain filling.

4. Strengthen field management

Sesame is particularly sensitive to water stains. If it is at full flowering stage, the leaves will be wilted after 3-4 days of watering, and the roots will turn black. Therefore, it must be drained and stained in time to preserve production. When the sesame blossoms, the stem is removed 3.3 to 6.6 cm on a sunny day, which is beneficial to saving nutrients and increasing yield. When the sesame seeds are 1-2 on the true leaves, they are sprayed with insecticides to prevent insect pests, and the buds are sprayed with 800-fold thiophanate-methyl or carbendazim to prevent diseases such as sesame blues and bacterial leaf spots. After the final flower, it gradually matures. When the pods turn yellow, nine mature can be harvested.

    Visual Testing is the most commonly used test method in industry. Because most test methods require that the operator look at the surface of the part being inspected, visual inspection is inherent in most of the other test methods. As the name implies, VT involves the visual observation of the surface of a test object to evaluate the presence of surface discontinuities. VT inspections may be by Direct Viewing, using line-of sight vision, or may be enhanced with the use of optical instruments such as magnifying glasses, mirrors, boroscopes, charge-coupled devices (CCDs) and computer-assisted viewing systems (Remote Viewing). Corrosion, misalignment of parts, physical damage and cracks are just some of the discontinuities that may be detected by visual examinations.
