What are the precautions for fertilizing wheat in winter
Wheat is divided into winter wheat and spring wheat, and now that winter has arrived, it is naturally winter wheat that is planted. When planting winter wheat, fertilization work also needs to be done well. Fertilizing winter wheat is a key measure to ensure that the wheat successfully overwinters, but fertilizing winter wheat is different from spring wheat. There are many areas that require our attention, so today the editor has brought you the precautions for fertilizing wheat in winter. Let's take a look below!
1. Control the amount used
The amount of fertilizer applied in winter is very important. First, we must apply sufficient base fertilizer, and the base fertilizer should be mainly fully decomposed farmyard manure. Then during the planting period, we should apply topdressing in a timely manner according to the soil fertility, the growth of the wheat, and the past yield of the plot. For example, plots with low to medium wheat yields in the past should have the amount of topdressing increased, which is very helpful for wheat growth and can effectively increase wheat yield. Conversely, for fields with higher yields, the amount of fertilizer applied can be appropriately reduced. The amount of fertilizer must not be too much, to prevent fertilizer burn in wheat and affect wheat growth.
2. Comprehensive nutrition
The nutritional needs of wheat growth are relatively comprehensive. When fertilizing, we must adjust the nutrient ratio in the fertilizer well, and must not apply only one kind of fertilizer alone for a long time. Ensure fertilizer diversity. Also, during the vigorous growth period of wheat, the main focus should be on improving the fertilizer conversion rate, understanding the nutrient needs of wheat at each growth stage, and trying to improve fertilizer utilization. During the vigorous period, the frequency of fertilization should be increased to meet the nutrients needed for wheat growth. Enhance the growth capacity of wheat, improve cold resistance, and prevent freezing damage.
3. Dig trenches and apply deeply
Many farmers apply fertilizer, especially urea, to the soil surface when fertilizing. After about 5 days, most of the nitrogen in the urea will volatilize. The utilization rate of urea is also seriously insufficient, which not only increases planting costs but also seriously affects wheat growth. Therefore, when applying urea, we should dig trenches and apply it deeply as much as possible, and the depth of the trench must be no less than 10cm. Only in this way can the volatilization rate of nitrogen be reduced, keep the fertilizer in a moist environment, improve the fertilizer conversion rate, and promote the absorption of soil nutrients.
4. Fertilization position
The fertilization position has a great impact on wheat growth. When fertilizing, we must keep a certain distance from the wheat. Because the fertilizer is rich in nutrients and has a very strong moisture-absorbing capacity, if it is applied too close, it is very easy to burn the wheat plants, causing fertilizer burn, harming wheat growth, and preventing successful overwintering. Therefore, when fertilizing, we must prevent the fertilizer from contacting the wheat roots, and it must not touch new leaves either, to prevent root burn and leaf burn. The method of digging trenches and applying deeply is a very good fertilization method. It can not only improve the fertilizer conversion rate but also prevent the above problems.
The above is a brief introduction to the precautions for fertilizing wheat in winter. In particular, the use of urea requires even more attention. After applying urea, do not water, because watering before the urea has completely decomposed will cause the loss of urea and lead to wasted fertilizer. That is all for today's introduction.
