There are also many people in the village who plant themWinter wheat。In the past, I have assisted my parents in planting winter wheat, and I have a certain grasp of this situation, so here are some of the farmers' opinions, and if there is anything inappropriate, I sincerely invite you to highlight it. Here, it is important to understand why wheat has clumping and cracks in the soil.
In fact, there are many factors that lead to soil cracks, and there are three specific points in summary: the first is that the water storage of the deep soil during the sowing period is insufficient, which will cause the soil seedling condition to be relatively poor, and it will drizzle from time to time.
Or after watering, the soil will collapse and cause cracks.
If the temperature does not rain for a long time, or if you do not hoe immediately after watering, the soil moisture on the surface of the wheat field will be lost, and soil clumps and cracks will occur. Soil clumps and cracks are usually worse when there is a prolonged drought. The third reason is that part of the land for comprehensive use of straw is not of high quality, and it is not timely to suppress it after the wheat is planted, which will also lead to soil cracks.
One of the common problems of soil in China today is soil agglomeration and cracking, which is caused by the use of organic fertilizers and chemical fertilizers, and the application of fertilizers reduces the soil organic matter, destroys the original soil colloid, and loses the soil permeability.
The application of chemical fertilizers kills the microflora in the soil and makes the soil lose its original vitality, and the soil is healthy and healthy by 3 million grams of microflora. comprehensive utilization of straw to improve the organic matter and air permeability of the soil; The application of organic fertilizer can improve the soil organic matter of the soil, and the application of organic fertilizer is more scientific and reasonable than the comprehensive utilization of straw; The flushing application of microbial agent is flushed together with irrigation, and biological bacterial fertilizer clay soil resources and saline-alkali soil are often used to pour seedling water. Because of the short tillage period of clay soil resources, the soil moisture loss is slow, and the water moisture at the bottom may be harmful to the appropriate time for sowing.
Saline-alkali soil can be pressed with salt and seedlings according to the way of watering the face water.
Because the probability of precipitation around the time of wheat sowing is higher, farmers have been sowing more and more wheat in recent years, which can save some capital investment, but when the soil water holding capacity is less than 60%, it is necessary to water the seedlings. Note: Wheat fields that are watered with face water or seedling water are prone to agglomeration and cracks.
Compared with the wheat field sown with sufficient moisture, the single tree has fewer headings, narrow leaves and thin stems, so when the seedlings are suitable after watering, they should be removed once. For wheat fields with moderate material (soil, light loam and sandy soil), the water that can produce seedlings should be minimized to water the face or seedlings.

Increase land fertilizer. This condition of the soil is most likely a sign of lack of fertility, so it is necessary to fertilize as soon as possible.
-
The soil can be caulked and fertilized with more water to deal with the cracks.
-
At this time, the soil must be loosened in time, and all the compacted parts must be raked, and then the ground must be re-leveled.
Relevant experts pointed out that due to the characteristics of the solid wood floor itself, once the installation and use are improper, even fully qualified products will have quality problems, so the maintenance of the floor is very important. >>>More
In fact, different scientists have their own explanations for the formation of this mysterious crop circle: meteorologists believe that it may be caused by cyclones or lightning, and geographers say that it is caused by some kind of magnetic field under the stratum. Some people think that this is a prank by some people, but all of these explanations are not entirely convincing. >>>More
Hello, glad to answer for you.
The principles and methods of dealing with concrete shrinkage cracks are roughly as follows: >>>More
Firstly, the shape and direction of the crack and whether there is a development trend are observed, the causes of the crack are analyzed, and the nature of the crack is determined. Determine whether the crack has an impact on the safety of the house structure, and if it does not affect the safety, it can be treated simply. Otherwise, professional and technical personnel should take appropriate technical means to reinforce the treatment. >>>More
