1. The original moisture of corn is large and the maturity is uneven. This will lead to corn fever.

2. The embryo of corn contains a lot of fat and is prone to rancidity.

3. The embryo of maize is rich in nutrients and has a large amount of microorganisms attached.

4. The embryo of corn is the first place damaged by insects and molds. After the embryo absorbs moisture, molds multiply in large quantities and begin to mildew at a suitable temperature.

this is the reason why corn has a fever in winter. Pay attention to the management of corn in peacetime, so as to make its corn grow and develop healthily.

Maize belongs to panicum miliaceum of Gramineae. Alias: corn, bonzi, baogu, baomi, baosu, Hosta, corn, pearl rice, Bao Lu and Da Lu Su, which are called pearl grains in northeast Liaoning dialect, coix seed in Chaozhou dialect, millet in Cantonese and fanmai in Minnan dialect.

Growing environment:

1. Temperature

Corn is a thermophilic crop, and higher temperature is required in the whole growth period. The biological effective temperature of maize is 1℃. Seed germination requires 6-1℃, below 1℃ germination is slow, 16-21℃ germination is vigorous, and the optimum temperature for germination is 28-35℃, and germination is stopped above 4℃.

2. Illumination

Corn is a short-day plant, which can blossom and bear fruit under short-day (8-1 hours) conditions.

3. Moisture

Corn has a tall plant and a large leaf area, so it needs more water. The optimum precipitation during maize growth is 41-64 mm.

4. Soil

Corn is not very strict with soil. Corn can be planted in chernozem, chestnut soil and sandy loam with loose soil, deep soil and rich organic matter, and the PH value is in the range of 6-8.

5. Nutrients

N, P, K, S, Ca and Mg are in great demand, while Fe, Mn, Zn, Cu, Ba and Cl2 are in less demand.
