Now that we have reached the sowing season of winter wheat, everyone is also preparing for the winter wheat planting. Winter wheat is relatively cold-resistant, but it also needs sufficient nutrients to improve the growth ability of winter wheat to ensure that wheat can successfully winter. However, many people do not strictly control the nutrient ratio of fertilizers, resulting in failure of wheat planting and extremely low yields. Today, Xiaobian brought you the characteristics of wheat renewal. Let’s take a look at it!
1, fertilizer characteristics
The fertilizer requirement of winter wheat is relatively large, and the demand for NPK fertilizer has different requirements. And the degree of demand for winter wheat varies greatly with the variety and growth stage of the winter wheat, and the proportion of nitrogen, phosphorus and potassium applied depends on the planting area, climate environment and planting method. However, there is still a general rule to follow. The demand for nitrogen, potassium and phosphorus in winter wheat is about 3:3:1 throughout the growing season.
2. Nitrogen fertilizer demand
The demand for nitrogen fertilizer in winter wheat is relatively large in the growing season, and the application of nitrogen fertilizer is controlled according to the growth schedule of winter wheat. When winter wheat is in the tillering stage, the demand for nitrogen fertilizer accounts for 1/5. Because when winter wheat is in the seedling stage, it is in winter, and the winter temperature is low, which is very unfavorable for the growth of seedlings. At this time, sufficient nitrogen fertilizer is needed to enhance the cold resistance of the seedlings and increase the growth rate.
Then, when the winter wheat grows to the jointing stage, when the winter growth ability is the strongest, the demand for nitrogen fertilizer will also rise. The whole growth period of winter wheat is the time of the greatest demand for nitrogen fertilizer. However, the nitrogen fertilizer should not be too much, otherwise it will lead to over-growth of tillers, which will lead to a prolonged phenomenon, resulting in a large population of winter wheat plants with poor quality.
3, phosphate fertilizer demand
When winter wheat grows to the flowering stage, the demand for phosphate fertilizer is the largest, and the demand for phosphate fertilizer during the flowering period reaches 7/10 of the total growth period of phosphate fertilizer. During this period, sufficient phosphorus should be ensured, which is conducive to the differentiation of winter wheat spikes and promote photosynthesis of wheat and increase the accumulation of carbohydrates in wheat.
Secondly, it is more important that when winter wheat returns to the green stage, although the demand is far less than the flowering stage, the phosphorus in the green stage has a great influence on the growth of winter wheat. It can promote the differentiation of winter wheat, improve the rooting ability of roots, and increase the number of tillers and new leaves. It can protect the winter wheat from good winter, so we must increase the proportion of phosphate fertilizer when applying the base fertilizer.
4, potash demand
The demand for potassium fertilizer in the early growth stage of winter wheat is not too high. When the maximum amount of potassium is needed, it is when the winter wheat grows to the booting stage. The amount of potassium required during this period can reach 3/5 of the total amount, which is also the best period for potassium conversion. At this stage, sufficient potassium fertilizer is provided to make the winter wheat grow robustly, improve the nutrient absorption and transportation of the plant, and speed up the grain filling. When winter wheat reaches the flowering stage, the proportion of potassium fertilizer can be slowly reduced, because potassium is too potassium to appear. Not only waste of fertilizer, but also reduce the amount of potassium fertilizer in the plant.
The above is a brief introduction to the characteristics of winter wheat needs fertilizer. Many friends only pay attention to the application of potassium fertilizer when planting winter wheat. Phosphorus and potassium are often neglected. The application of nitrogen fertilizer for winter will not only lead to insufficient nutrition of winter wheat, but also prone to various problems, which will have a greater impact on the growth of winter wheat.
