What to do about wheat seedling death in winter and spring? The latest solutions are here
Wheat is one of the main food crops in our country, and it is widely planted mainly in the northern regions of our country. Wheat cultivation is generally dominated by spring wheat and winter wheat, and when planting wheat, many problems can arise, affecting wheat yield and quality. Among them, seedling death in winter and spring is one of these problems, so what should be done about wheat seedling death in winter and spring? The main approach is still prevention. Below, the editor will briefly introduce it to everyone. Let's take a look together!
1. Timely winter irrigation
When planting winter wheat, winter irrigation should be carried out at the right time. Timely winter irrigation can not only control soil temperature and help form a high-quality soil environment. It can also regulate nutrients in the plow layer, increase the heat capacity of the soil, promote wheat rooting and more tillering, and improve the rate of strong seedlings. It can also avoid seedling death from freeze damage, achieve the goal of preserving seedlings through the winter, and reduce late spring cold spells. At the same time, this is also a key measure to prevent wheat seedling death in winter and spring.
In addition, reasonable winter irrigation can also settle the soil and eliminate overwintering pests lurking in the soil. During winter irrigation, if it is combined with fertilization work, it can also create a good growing environment for wheat greening in the second year and for the roots. It speeds up wheat growth, achieves the goal of improving wheat quality, and increases yield. Moreover, if winter irrigation is carried out on saline-alkali land, it can also improve the soil environment. There have also been professional data surveys showing that plots with reasonable winter irrigation have a noticeably higher yield than plots without winter irrigation.
2. Timely compaction
Compacting the soil is also a main measure to avoid wheat seedling death in winter and spring. Carrying out timely compaction in winter can break up large soil clods and lumps in the soil. It fills the gaps in the soil and compresses the soil. This increases the contact area between wheat roots and soil, promotes tight integration, and enhances the growth and development capacity of wheat roots. At the same time, reasonable compaction can also improve the soil's moisture retention capacity, ensure normal wheat growth in winter and spring, and reduce seedling death.
3. Reasonable covering
Doing a good job of covering in winter can deepen the depth at which the wheat tillering nodes enter the soil, protect the leaves near the ground surface of the plant, prevent excessively rapid water evaporation, and improve water regulation, thereby achieving the effect of heat preservation and freeze protection. Generally, keeping the soil covering depth at about two cm can achieve a good effect of freeze protection and seedling preservation. For wheat fields with soil covering, the ridges should also be cleared in time in spring. When the temperature reaches about 5 degrees, the covering soil should be cleared out of the field. If the wheat variety has poor cold resistance and was not sown deeply, then soil should be covered earlier. Reasonable soil covering can effectively increase temperature and preserve moisture, avoid wheat freeze damage, and reduce death from freezing.
The above is a brief introduction to what to do about wheat seedling death in winter and spring. That is all for today's introduction. This article is for reference only, and I hope it can be helpful to everyone!
