What category does corn belong to? What kind of corn does corn belong to?

Corn belongs to the category of food crops, yesPoaceaeof annual herbaceous plants. Also known as bud valleyBud riceSticksMaizeCompared with traditional rice, wheat and other food crops, corn has strong drought tolerance, cold tolerance, barrenness tolerance and excellent environmental adaptability.

Corn is an important crop, in addition to making grain, it is also used to make fodder and ethanol.

etc., widely used. According to the physiological characteristics and external morphological changes, the life cycle of maize can be divided into three different growth stages (seedling stage, ear stage, flowering and grain stage) and 12 growth stages. In terms of picking time, sweet corn is generally sown in spring.

22 days after tasseling, waxy maize.

25 days after tasseling.

Corn species

1. Sweet corn: Sweet corn endosperm contains more sugar and water, and when it is ripe, it is shrunken or shriveled after the water evaporates, and sweet corn not only has high sugar content in the endosperm, but also has different endosperm properties from ordinary corn. According to the genotype and endosperm properties of sweet corn, it can be divided into ordinary sweet corn, fortified sweet corn and super sweet corn.

2. Waxy corn: also known as sticky corn, originated in China, because its endosperm starch is almost entirely composed of amylopectin, it tastes sticky and sweet and delicate, and has a good taste, which is an ideal type of fresh food. The difference between amylopectin and amylose is that the molecular weight of the former is much smaller than that of the latter, and the digestibility of eating is more than 20.

3. High oil corn: refers to the type of corn with an oil content of more than 8 grains, due to corn oil.

It mainly exists in the embryo, and intuitively it seems that high-oil corn has a large embryo.

4. High-starch corn: refers to special corn with a starch content of more than 70. In common corn grains, amylose accounted for about 27 percent of starch content, and amylopectin accounted for about 73. 100% of waxy corn is amylopectin.

Corn belongs to the category of food crops. Compared with traditional rice, wheat and other food crops, corn has strong drought tolerance, cold tolerance, barrenness tolerance and excellent environmental adaptability. Corn has a high nutritional value and is an excellent food crop.

As a high-yield grain crop in China, corn is an important feed for animal husbandry, aquaculture, aquaculture, etc., and is also one of the indispensable raw materials for food, medical and health, light industry, chemical industry, etc. Because maize resources are extremely abundant, cheap and easy to obtain, they also have many biological activities, such as antioxidant, anti-tumor, hypoglycemic, improve immunity and bacteriostatic sterilization, etc., and they have broad development and application prospects.

Cereals. Corn is also known as bread grain.

Bud rice, pearl rice, is a monocotyledonous class Poaceae, Poaceae, maize species, belonging to the class of food crops. Corn is rich in dietary fiber as well as natural vitamin E

Progesterone and other nutrients have a variety of effects such as preventing and treating constipation, protecting, stopping bleeding and stopping diarrhea.

Physical characteristicsThe physical traits of maize were composed of grain color, grain shape, seed coat luster, grain length, grain width, 100-grain weight, grain size, grain uniformity and hardness. The color of corn kernels consists of three parts: seed coat, aleurone layer (rich in protein, also known as protein layer), and endosperm. In most cases, the color of the endosperm of mature corn grains is yellow or white, and the seed coat and aleurone layer are colorless and transparent.

Depending on the color of the corn kernels, there are three types of corn: yellow corn, white corn, and mixed corn. According to the morphology, hardness and different uses of corn, corn is divided into ordinary corn (hard grain type, intermediate type, horse tooth type, hard horse type, horse hard type) and special corn (high lysine corn, high oil corn, sweet corn).

Burst corn, waxy corn. Both.

Corn belongs to the cereal class.

Maize is a cereal food crop. Corn, also known as baogu, bud rice, pearl rice, is a monocotyledonous poaceous order Poaceae, maize species, belongs to the class of food crops.

Corn loves light, is not shade tolerant, and is a short-day plant. Corn is temperature-loving, suitable for growth temperature of 22-30, seed germination temperature of 6-10, jointing temperature of 15-27, flowering temperature of 25-26, grain filling temperature of 20-24.

How to grow corn:

1. Planting time.

Corn likes to grow in a warm environment, if you want to plant it, then you first need to choose the right planting time, according to the habits of corn, it is better to plant in April and May in spring, and you can also plant in mid-July, not too early or too late, otherwise the temperature is not suitable to easily lead to poor growth of corn plants.

2. Soil preparation and fertilization.

When planting corn, it is suitable to choose loose, fertile and well-drained plots, before planting, the soil needs to be deeply turned, and an appropriate amount of fertilizer should be applied to the soil as base fertilizer, so that the soil can be more loose and fertile, and corn can grow more vigorously after planting.

3. Sowing and planting.

After digging a trench for the plot, prepare the corn seeds of suitable varieties, and then sow them into the soil according to a certain plant spacing, and cover a thin layer of soil after sowing, and water appropriately, so that the soil is in a slightly moist state, and soon the corn can emerge and grow.

4. Maintenance management.

After the emergence of corn seedlings to do a good job of maintenance management, timely pull out the weak seedlings of the diseased seedlings, too dense seedlings also need time seedlings, in the corn seedling growth period, to regularly loosen the soil and weed, but also need to apply thin fertilizer frequently, to promote the vigorous growth of plants, pay attention to prevent pests and diseases, so as not to attack the plant by the fungus.

Common corn, sweet corn, black corn, waxy corn.

Nutritional value of common corn:

1. Ordinary corn.

Rich in dietary fiber, including cellulose, hemicellulose, pectin and lignin.

2. Sweet corn.

Sweet corn contains fructose, sucrose, glucose, but also contains protein, crude fat and water-soluble protein, which is higher than ordinary corn, and it also contains amino acids, carotene, vitamin C, vitamin E, its nutritional value and health care effect is the highest in the staple food, and also contains anti-aging signs, vitamin E, fatty acids, selenium, magnesium, vitamins and so on.

3. Black corn.

Black sweet corn has great nutritional value, high trace element content, 2-8 times that of other grains, and high lysine content, which is a high-reliance crop. According to expert analysis, it belongs to the variant that changes the amino acid composition pattern of corn endosperm protein, and the lysine content increases significantly, which greatly improves the nutritional quality of its protein.

4. Waxy corn.

Waxy corn has a high starch content, up to 75 percent, and contains a variety of vitamins and proteins, and waxy corn also contains some carotene that is not found in sweet corn. What's more, waxy corn has a much smaller molecular weight than sweet corn, so it is easier to digest.

How to pick fresh corn

1. Look at the corn kernels.

First of all, we will peel off the corn husk to see if the corn kernels are full, if the corn kernels are full and very elastic, bright color, it is very good corn, you can choose home.

2. Smell it.

Learning to smell corn is also an important way to tell if corn is fresh. We can smell the corn closely, fresh corn will have a fragrant smell, if it is not fresh corn will not have any taste, and there may be a taste of spoiled kernels.

Hello, I have seen your question and am sorting out the answer, please wait for a while The varieties of corn seeds include Zhengdan 958, Lianyu No. 1, Xianyu 335, Denghai 605, Jingke 968, Jundan 20, etc. Corn seed is a propagule with a corn plant, composed of seed coat, embryo and endosperm, corn seed needs to be inspected and repaired before storage, and the warehouse is sterilized, during storage, the corn seed needs to be dried, and the temperature of the warehouse needs to be guaranteed will not change significantly.

Zhengdan 958: Zhengdan 958 is a new hybrid corn variety selected and bred by Henan Academy of Agricultural Sciences, which can harvest 75 kg of corn per mu and 150 kg more than the general variety, Zhengdan 958 has uniform ears, fine shaft, deep grains, no bald tips, no empty stalks, and the annual difference is very small, and the stable yield is good. Xianyu 335:

Xianyu 335 is an ordinary corn variety, with yellow grains, semi-hard grains, and 100 grains, suitable for summer sowing and planting in Henan, Hebei, Shandong, Shaanxi, Anhui and Shanxi Yuncheng, and should be used with caution in areas where leaf spot disease and dwarf mosaic disease are recurred. Denghai 605: Denghai 605 seedlings have purple leaf sheaths, green leaves, green leaf margins with purple bands, anthers yellow-green, and light purple glume shells.

The plant type is compact, the plant height is 259 cm, the ear height is 99 cm, and the number of adult leaves is 19 20.

Sweet corn, waxy corn, high-oil corn, colored corn, and popping corn. Among them, popping corn is mainly used to make popcorn corn, and sweet corn can also be divided into ordinary sweet corn, fortified sweet corn and super sweet corn, which can be cooked and eaten, raw or canned and other non-staple foods. White corn, yellow corn and black corn are boiled, the color is bright, crystal clear, and the taste is relatively sweet.

1.Sweet corn.

Sweet corn is one of the corns, which contains more water-soluble polysaccharides and vitamins in the body, which is easy to be digested by the human body. When planting sweet corn, it is necessary to choose the right soil, and it is best to use sandy loam soil with rich trace element content and good drainage to plant sweet corn so that the plant can grow better.

2. Black corn.

Black corn is also a type of corn, which is rich in lysine, which can regulate the metabolism of human fat. When maintaining black corn, you can water mineral-rich river and lake water for the plants to keep the soil in a moist state, and you need to pay attention to the amount of watering when watering, so as to avoid water accumulation on the plants.

3. Waxy corn.

Corn also includes waxy corn, which is soft and waxy in taste and rich in manganese and zinc. It is best to use fertilizer based on nitrogen fertilizer during the growth period of the plant, and use fertilizer based on phosphorus and potassium fertilizer during the flowering and fruiting period of corn.

4. High-oil corn.

Corn also includes high-oil corn, which has a high oil content and can be used as a raw material for corn oil, or can be eaten after cooking, and can provide all-day sunshine for plants when maintaining high-oil corn, so that plants can photosynthesize normally and store enough nutrients for flower bud differentiation.

Maize is a genus of grasses, maize, and maize species. According to the botanical characteristics and biological characteristics of maize, there were 9 kinds of corn according to the external morphology and internal structure of grains, including hard grain type, horse tooth type, intermediate type, waxy type, burst type, sweet type, powdery type, sweet powder type and barn type.

1. Sweet corn. Generally, it is divided into ordinary sweet corn, fortified sweet corn and super sweet corn. Sweet corn has strict requirements for production technology and harvest date, and the life span of sweet corn is relatively short, and China's current sweet corn can basically meet the market demand.

2. Waxy corn. Its production technology is much simpler than that of sweet corn, there are almost no special requirements compared with ordinary corn, the harvest period is more flexible, the shelf life is relatively long, and there is no need for special storage and processing conditions. In addition to fresh food, waxy corn is also an important raw material for starch processing industry.

China's waxy corn breeding and production are developing very fast.

3. High-oil corn. The oil content is high, especially the content of unsaturated fatty acids such as linoleic acid and oleic acid reaches 80%, which has the effect of reducing cholesterol in serum and softening blood vessels.

4. High-quality protein corn. The yield is not lower than that of ordinary corn, and the whole grain lysine content is 80-100% higher than that of ordinary corn, and in some areas of China, a combination of high yield and high quality has been achieved.

5. Purple corn. It is a very rare corn variety, which is called "black pearl" because of the shape of the grains like pearls. Although the quality of purple corn is excellent and specific, the cob is small, the grain is few, and the yield per mu is only about 50 kg.

1.Today I will introduce you to the simplest variety classification of corn, this classification method is divided according to the color of corn kernels, the first variety is yellow corn, that is, the kind of corn that we often see in our lives, the color of corn kernels is yellow, and it is more delicious to eat.

2.The second kind of corn refers to the corn with white corn kernels, we call this type of corn white corn, many people may feel scared when they see white corn, but we will inevitably see a white corn in a lot of yellow corn in the planting process, and as long as the other color content of white corn does not exceed 2%, it can be eaten normally.

3.With white corn, there is black corn, black corn is a special type of corn, the color of black rice is black, because it contains relatively high melanin, everyone can help the hair become more black after eating some black corn, and more bright.

4.The fourth kind of corn is called waxy corn, this kind of corn is often called sticky bud rice in life, and usually, waxy corn is the most popular diet for everyone, because it tastes sticky and sweet.

5.The last type of corn is miscellaneous corn, and by miscellaneous corn we mean corn with mixed colors.
