What are the planting methods of corn? I can't believe this doesn't grow sticks!

Corn is one of the most important foods in the world, about one third of the world's population to it as the main food, it is also an indispensable feed for livestock and fish. So, what are the methods of corn cultivation? Let me introduce you here.

1. What are the cultivation methods of corn?

1, soil: corn soil requirements are not very strict, loose soil, deep soil, rich in organic matter chernozem, chestnut soil and sandy loam, pH value in the range of 6-8 can be planted.

2. Temperature: Corn is a thermophilic crop. Seed germination requires 6-10℃, the optimum temperature for germination is 28-35℃, seedling stage can withstand short-term low temperature of-2--3℃, jointing stage requires 15-27℃, flowering stage requires 25-26℃, filling stage requires 20-24℃; early maturing varieties require accumulated temperature of 2000-2200℃, medium maturing varieties 2300-2600℃, late maturing varieties and 2500 - 2800 (3000) ℃.

3, light: corn is a short-day plant, in short days (8-10 hours) under the conditions of flowering and fruiting, according to research, blue and other short-wave corn development fast, and in the morning or evening with red and other long-wave development fast.

4, water: corn water demand is more, the most suitable precipitation during the growth period is 410-640mm, summer is less than 150mm area is not suitable for planting corn; and excessive precipitation, affecting light, increase disease, lodging and weed damage, but also affect corn yield and quality improvement.

5. Fertilization: apply 2000-3000kg of high-quality manure per mu as base fertilizer before sowing, 4-5kg of sulfuric acid per mu, 15-20kg of calcium superphosphate per mu, 2-3kg of chlorine fertilizer per mu when sowing, topdressing nitrogen fertilizer at jointing, booting, tasseling and flowering and filling stages, and applying nitrogen 10 - 20kg/mu during the whole growth period.

6. Diseases and pests: diseases mainly include leaf spot, head smut, smut, black-streaked dwarf disease, bacterial wilt, etc., pests include armyworm, corn borer, mole cricket, ground tiger, white grubs, etc., and measures such as selecting disease-resistant varieties, strengthening cultivation management, rational rotation and chemical control should be taken in time for prevention and control.

Second, this kind of "corn" does not grow cobs!

This kind of corn without cob is Mexican corn grass, which originated in Mexico and Caribbean Islands and Argentina. China introduced it from Japan in 1979 and is currently planted in Guangdong, Guangxi, Fujian, Zhejiang, Jiangxi, Hunan, Sichuan and other provinces. Its stems and leaves taste sweet, crispy and juicy, palatability is excellent, cattle, sheep, pigs, rabbits, geese and so on are fond of eating, but also the first choice of herbivorous fish pasture, digestion and conversion rate is high, than corn with cob benefits many times higher.

The plants of Mexican corn grass are very similar to corn, but its ramets are much stronger than corn, each plant can be divided into more than 20 plants, and the number of plants can reach 60-70; its regeneration ability is strong, 30 days after sowing enters the rapid growth period, 45 days after sowing begins harvesting, and then every 20 days can be cut again. The whole growth period can be cut 8-10 times. If properly managed, it can produce 10 - 30,000 kg of green forage grass per mu. It has stronger adaptability to harsh environment, heat and drought resistance, salt and alkali tolerance, and can be planted in any area where corn can be planted, and it can be sown all the year round in the south.

The above is the corn planting methods and not long cob Mexican corn grass introduction, I hope useful to everyone.
