When picking corn, but also according to their own taste to decide to buy which kind of corn, usually, white is glutinous corn, yellow is sweet corn, some colorful is also sweet corn. What are the contraindications of colorful corn? Now follow me to learn about the taboos of corn.

Corn food taboos

1. Eat corn should be the tip of the kernel of corn all eaten. This is mainly because many of the nutrients of corn are concentrated here. In the endosperm of young corn kernels, the content of unsaturated fatty acids reaches 85% and is rich in vitamin E.

2. Moldy corn can not be eaten. Moldy and spoiled corn will produce toxic substances? Aflatoxin. Aflatoxin is produced by a series of mold metabolism carcinogens, mainly damage to human and animal liver tissue, serious cases can lead to liver cancer or even death. In addition, moldy corn will also reduce immunity, so moldy corn should never be eaten.

3. Pay attention to food matching. Corn and conch eaten together, will cause discomfort; and snails eaten together easily poisoned, the ground syrup water can be detoxified.

4. Corn in the digestive process will produce more gas, wait until bedtime, the digestion of the unfinished gas will produce a feeling of bloating, preventing normal sleep, so try to eat less corn for dinner.

Reasons affecting the yield of corn

First, the selection of seeds is not careful. To go to the formal seed management department, choose the good seed suitable for the region to plant, is to realize the premise of high corn yield.

Second, the density is too high. Some farmers in order to achieve the purpose of high yield, blindly increase planting density, resulting in excessive plant density, resulting in poor growth and development of corn monocultures, high rate of empty stalks, spikelet bald tip serious, so that varying degrees of inversion, thus resulting in a reduction in yield. Reasonable dense planting is an important part of realizing high yield of summer corn, according to the characteristics of different varieties, choose different dense planting range. Even the density of the same variety, but also depending on the geophysical, sowing period and flexibility, high soil fertility or late sowing should be dense, lower and middle fertility plots or early sowing should be thin.

Third, fertilization is not scientific. Agricultural production in the prevalence of heavy nitrogen fertilizer, light phosphate fertilizer, ignoring the phenomenon of potash and micronutrient fertilizer, due to the application of nitrogen fertilizer too much, maize tends to poor resistance to reversal of the phenomenon of serious pests and diseases, resulting in varying degrees of yield loss. Phosphorus and potash fertilizer and micronutrient fertilizer should be used as seed fertilizer deep or early in the pre-extraction application, nitrogen fertilizer should be phased in, in the extraction period of the total amount of nitrogen fertilizer 2/3, trumpet period 1/3. In addition, the application of foliar fertilizers during the growth period, you can achieve a significant increase in yield.

Fourth, watering is not timely. Some farmers do not water according to the law of corn watering, often found dry before watering, thus missing a good time to promote plant growth and development. Under the premise of sowing in sufficient moisture, we should pour good water in a timely manner, tasseling and blossoming water and grouting water to meet the water needs of plant growth and development.

Summer planting corn fertilization methods

A good base fertilizer and seed fertilizer summer corn should be applied before sowing a good base fertilizer, mainly organic fertilizer, can also be used to implement the previous crop of wheat straw directly back to the field, but should be equipped with the appropriate amount of nitrogen fertilizer, adjust the carbon and nitrogen ratio to accelerate the decay of the straw. Seed fertilizer is mainly fast-acting nitrogen, phosphorus, potassium fertilizer, such as diammonium phosphate (5-10 kg per 667 square meters), potassium sulfate compound fertilizer (45% of the content of 10-15 kg per 667 square meters) and so on.

Second, proper fertilization is very critical Fertilization in the growth of maize has a pivotal role, fertilizer to fast-acting nitrogen-based, and according to the maize of different reproductive periods with phosphorus, potassium fertilizer. Usually three times fertilizer, that is, seedling fertilizer, nodulation fertilizer, spike fertilizer. Summer corn in the plucking and tassel period of nitrogen, phosphorus, potassium demand are more, so it should be based on the specific situation with phosphorus, potassium fertilizer.

Third, the clever use of foliar fertilizer in the corn nodulation period sprayed 0.2% -0.3% of potassium dihydrogen phosphate 2-3 times, can make the corn yield more than 10%, in the seedling and nodulation period sprayed 0.1% -0.3% of zinc sulfate aqueous solution can prevent the occurrence of corn white seedling leaf disease.
