Description
Technical Field
The invention belongs to the technical field of agricultural crop planting, and particularly relates to a fresh corn planting method suitable for northern areas.
Background
Corn, also known as maize, corn, and the like, belongs to the genus Zea of the family Gramineae, is an important grain crop, feed crop, and light industrial raw material crop, is one of important grain and industrial raw materials required by the world population, and is one of the most widely distributed grain crops in the world. The planting area of the corn is second to the wheat and the rice and is third. China is in the golden corn growing zone, is the second largest corn producing and consuming country next to the United states, and corn is developed into the first largest economic crop in China. The corn is rich in necessary nutrients such as carbohydrates, proteins, vitamins, dietary fibers, minerals and the like, and particularly, the corn contains rich zeaxanthin, linoleic acid and glutathione. Because the zeaxanthin is a component of human retina, the linoleic acid is essential fatty acid required by human body, the glutathione has the effects of improving the immunity of the organism and resisting cancer, the dietary fiber has the functions of delaying the rise of blood sugar, clearing away intestinal rubbish and the like, so that the whole body of the corn is a treasure, and the zeaxanthin has an important function of adjusting the abnormal metabolism of the human body.
The research shows that the corn is a typical temperature-loving crop, the effective accumulated temperature from sowing to seedling emergence is 79.8 ℃, the biological lower limit temperature is 9.3 ℃, and the yield is seriously reduced when the average temperature is lower than 10 ℃, so that the control of the temperature is very critical to the planting of the corn. In northern China, especially in northeast China, due to the fact that wind is plentiful in spring and the temperature change is large, corns often encounter a low-temperature period after the corns are sowed early in the moisture retention period, the germination of seeds is seriously influenced, and the phenomena of seedling shortage and ridge breaking are caused. Statistics show that the annual yield of corn varies greatly in the northeast region, and low temperature variation is the most important factor in addition to production conditions and drought limitations. According to meteorological data, serious low-temperature cold damage occurs at intervals of 3-5 years in northeast regions, so that the yield of the corn is reduced by about 15%, and even if the corn is planted in normal climate, the corn yield is still different from that of other non-northern regions.
More importantly, for northern areas, due to the limitation of regional climate temperature and rainfall, spring corn can be planted only in late april, and harvest time reaches the bottom of august or even september, which seriously affects the planting opportunity of autumn corn (seeding cannot be delayed from 7 middle days, harvesting in middle and late 10 months), so that the planting of northern corn can be finished only one crop per year, and the planting yield of northern corn is seriously affected.
Therefore, how to effectively improve the cold resistance of the corn and adapt to the planting conditions of northern cold climate has important significance for the planting of northern corn.
