The corn seeds of Zhongbang 1 are better than Zhongbang 6.

Zhongbang No.6 is very famous. In fact, the variety of corn is not the main reason, and the later management work, such as pest control, temperature control and water and fertilizer management, can also produce high yield.

Corn generally refers to the millet of Gramineae and Zea, commonly known as corn. It is panicum miliaceum, with an erect stem and usually no branches. It is a short-day plant with suitable growth temperature of 22-30℃, seed germination temperature of 6- 10℃, jointing temperature of 15-27℃ and flowering temperature of.

There are many varieties of corn, which are generally divided into edible and feed varieties, vegetable varieties (including waxy type, sweet type and corn shoot type) and processed varieties (sweet corn and corn shoot type) according to their uses.

First, planting time

Sweet corn is generally planted later than grape corn. The germination ability of this plant is relatively low, which requires a high ground temperature. Usually, seeds will take root when the temperature is higher than 12 degrees, which is usually about 7- 10 days later than ordinary corn. If you plant it too early, there will be the possibility of rotten seeds.

Second, soil preparation and fertilization

Before planting corn, it must be carefully prepared. Corn seeds are small, and if the soil particles are large, it will affect its development. First, the soil is plowed for about 20-30 cm, and at the same time, sufficient base fertilizer+organic fertilizer+calcium superphosphate+potassium sulfate+zinc sulfate is applied. The trace element fertilizer chelated by bird's nest in the later stage can be directly used as topdressing.

Third, sow.

After corn seeds are sown in the soil, attention should be paid to controlling the density when planting. Generally, early-maturing varieties can be larger, and late-maturing varieties should be thinner. Pay attention to covering with plastic film after sowing, which can also play a role in heat preservation.
