When will the corn be sown in spring? What is the reason for the poor emergence rate?

Spring is a sowing season. Farmers need to start busy at this time. Many food crops are sown at this time. Corn is the same. It must be sown at the right time. When is the best time? What causes the emergence rate of maize to be poor? Below is the website to inform everyone!

When is spring corn sown? Spring corn in southern China is planted from mid-to-late March to April. Corn planting is a very important thing, if the spring corn planting too early, because the outdoor temperature is too low, above a certain level of harm corn early emergence rate. If spring corn is planted too late, in mid-late April or mid-late April, then the harvested corn will harm the growth and development of corn in the next season. In southern China, corn is planted in two seasons every year, early corn and late corn. As mentioned above, early corn is planted from mid-to-late March to April, and late corn is generally planted from mid-to-late July.

2. What causes the poor emergence rate of corn? 1. Drought is a key factor that endangers the emergence rate of maize planting. Because of the lack of water, many nutrients in the tender leaves of corn grains cannot be dissolved normally, and there is no sufficient balance between supply and demand of nutrients, which is also important to harm the early emergence rate of corn grains. 2. The quality of the corn seed itself is unqualified, such as the application of expired corn seeds, or the corn seeds have already rotted and deteriorated before leaving the bed. 3. The pecking of turtledove and * chicken? For this reason, many friends do not know much about it, but I think it is not easy for friends living in the countryside to become unfamiliar. Living in the countryside for decades, every spring when the family grows corn, the net editor has to deal with turtledoves and chickens. Turtledoves generally go out in broad daylight to peck corn in the field, and chickens generally go out at dusk and morning to peck corn in the field. Because corn seeds are not planted very deep, they can easily dig the kernels out of the soil with their forepaws.

III. What should I do if the emergence rate of corn is poor? 1. The planting rate of corn fields is poor. The area that people must pay attention to most is the balance of water supply and demand. Water injection is not enough * soil drought is too unfavorable for corn germination, water injection is too much * soil is too wet and cold, so that * soil co2 composition is not enough is also unfavorable for corn germination. 2. The balance of supply and demand of liquid fertilizer was also the primary condition to harm the emergence rate of maize seeds. Corn planting early corn seeds also have germination before not too much fertilizer, about half a barrel of organic fertilizer diluted into two cans of water, liquid fertilizer first bed and then under the corn seeds, finally in the corn seeds scattered on a thin layer of uniform fertilizer can be.

From the above we can understand the best sowing time of spring corn every year from mid-to-late March to April, earlier or later than this time range is a certain harm, generally leading to poor corn emergence rate is the above three, the net editor also shared some relative prevention methods for everyone, looking forward to assisting everyone.
