The production of sweet corn
The production of Sweet Corn ear has strong seasonality, is not resistant to storage, and has a short shelf life, and it is difficult to meet the regular needs of the people. For the preservation and preservation of sweet corn ear, the following aspects should be paid attention to through production practice and scientific research.
1. Harvesting sweet corn of different varieties timely, different climatic conditions and different cultivation techniques, sweet corn ear harvest time is not the same. After taste evaluation and sugar content measurement, generally 18-24 days after the filaments were extracted. Experience has shown that sweet corn ear harvesting is premature, yield is low, sugar content is insufficient, and the aroma is not strong. When harvested too late, most of the sugar in the sweet corn ear is converted into starch, the grain is aged, the epidermis is hardened, and the flavor is not good. Generally, when the Sweet Corn Kernels are full and full, and the skin is broken by hand, the outflow of the white milk is adequate and the harvesting is appropriate.
2. Harvest time and technology The morning and evening are the better times for harvesting sweet corn ear, take the outside temperature lower, so that the heat in the field will be reduced to facilitate faster pre-cooling. At noon high temperatures, should not be harvested.
When harvesting sweet corn ear, it should be removed from the plant together with the loquat leaf. Because there was a significant difference in the rate of decline in the amount of sugar in the loquat leaves and the loquat leaves after harvest. After the ear of the temporal lobe was left for 1 hour, the sugar content began to decrease, and the rate of decline decreased after 4 hours. On the other hand, the sugar content in the leaves of the loquat leaves was relatively stable, with little change at 4 hours after harvest. In the process of picking, the pressure and damage of sweet Corn Kernels in the loquat leaves are prevented. After harvesting sweet corn ears, they should not be piled up under high temperatures for a long time to avoid the sun and rain. They should be shipped back to cold storage and precooled.
