"Before the wheat was sown, a lot of corn seedlings grew in the field.
"Wheat is well sown, wheat has just emerged, there are many corn seedlings in the field, no less than wheat seedlings"
"Obviously, the wheat planted, the result is that there are more corn seedlings than wheat seedlings, is this a wheat field or a corn field?"
According to some growers, the above situation has occurred more this year, because when using a crawler harvester to harvest corn, more corn kernels are dropped, resulting in a lot of corn seedlings in the field.
The first case: when the corn is harvested, a lot of corn kernels are dropped in the field, and after the harvest, the local rainfall is more, which delays the sowing time of the wheat, resulting in the wheat not being sown for ten and a half days after the corn harvest, and the corn in the field has begun to sprout seedlings.
The second situation: when sowing wheat, it is necessary to prepare the land, when ploughing and spinning the land, the corn is turned into the soil, when the wheat is sown, the wheat germinates out of the seedlings, the corn also sprouts out of the seedlings, resulting in many corn seedlings after the wheat seedlings.
Will it affect wheat growth?
From the analysis of the growth process, the corn seedlings in the wheat field will affect the growth of wheat to a certain extent.
Wheat from germination to emergence, as well as the growth of seedlings, need to consume water and nutrients in the soil, while corn germination to seedling emergence and seedling growth, also consume water and nutrients. Soil moisture and nutrients are not unlimited, especially for nutrients, mainly rely on the supply of bottom fertilizer, when corn and wheat compete for water and nutrients, it is bound to affect the normal growth of wheat, resulting in wheat can not absorb enough impact, easy to form yellow seedlings or weak seedlings.
Some people say that the impact of corn seedlings is greater than the impact of straw returning to the field, and it depends on which point of view, if only from the perspective of nutrient supply, this statement is also true.
In addition, corn harvest when the grain, is a normal phenomenon, but the fall more than less, in previous years most of the farmers harvested is corn cob, the situation is not too obvious, this year due to rainfall, many farmers use the crawler harvester, harvest is corn kernels, so the corn kernels fell obviously, there are more follow-up corn seedlings. It not only causes a decrease in corn yield, but also affects the growth of wheat under the stubble, so it is still necessary to try to avoid the occurrence of grain loss when corn is harvested.
What should I do with corn seedlings in a wheat field?
From the actual planting process to analyze, most of the farmers will not care about it, wheat is a strong hardy crop, can withstand the winter cold, and corn is a warm crop, not hardy, wait until the winter cooling comes, will gradually wither, wait until the wheat returns to green years, wheat continues to grow, corn is gone. So, leave it alone and let it fend for itself. When the wheat returns to green in the next year, more urea is applied to supplement the nutrients needed for wheat growth.
In addition, for farmers who want to prevent corn seedlings, normal spraying of wheat field herbicides can also have a weeding effect on corn seedlings. Maize belongs to the crops of the grass family, so when wheat is sprayed with grass herbicides, it can not only control weeds in the field, but also remove the corn seedlings.
Wheat field grass herbicides mainly include alkyne ester, flurazosulfuron, alfonamide, azoline grass ester, methyl disulfuron, etc., sprayed these herbicides years ago, the control of grass weeds, the prevention effect on corn seedlings is also good.
In summary, there are many corn seedlings in the wheat field, which is a normal phenomenon in the planting process, because the corn is harvested, the fallen corn kernels are caused, it can be left to fend for itself without deliberate management, and it can also be controlled according to weeds, and the wheat field herbicide can be sprayed normally.
Ask your friends, this year's wheat planting, have you encountered a situation where there are corn seedlings in the wheat field?
