Matters needing attention for fertilization of wheat in winter

Wheat can be divided into winter wheat and spring wheat, and now it is natural to grow winter wheat after entering winter. Fertilization also needs to be done when planting winter wheat, which is the key measure to ensure the success of winter wheat, but the fertilization of winter wheat is different from that of spring wheat. There are a lot of places we need to pay attention to, so the editor today brings you some points for attention on wheat winter fertilization, let's take a look at it!

1. Control the dosage

The amount of fertilization in winter is very important, we should first apply sufficient base fertilizer, the base fertilizer is mainly fully mature farm manure. Then during the planting period, we should apply fertilizer in time according to the soil fertility, wheat growth and previous plot yield. For example, in the past, the plots with medium and low wheat yield should increase the amount of topdressing, which is of great help to the growth of wheat and can effectively improve the yield of wheat. On the contrary, the fields with higher yield can appropriately reduce the amount of fertilizer application, and the amount of fertilizer should not be too much, so as to prevent fertilizer damage to wheat and affect the growth of wheat.

2. Comprehensive nutrition

The nutritional needs of wheat growth are relatively comprehensive, we should adjust the proportion of nutrients in fertilizers when applying fertilizer, and we should not apply a certain kind of fertilizer alone for a long time. Ensure the diversity of fertilizers. And in the peak growth period of wheat, we should mainly improve the fertilizer conversion rate, understand the nutrient requirements of wheat in each growth stage, and improve the utilization rate of fertilizer as much as possible. In the peak period, it is necessary to increase the frequency of fertilization to meet the nutrition needs of wheat growth. Enhance the growth ability of wheat, improve cold resistance, and prevent frost injury.

3. Deep application of trenching

When applying fertilizer, many farmers will apply fertilizer, especially urea, to the surface of the soil, so that part of the nitrogen in urea will be volatilized after about 5 days. The utilization rate of urea is also seriously insufficient, which will not only increase the planting cost, but also seriously affect the growth of wheat. Therefore, when we apply urea, we should try our best to open the ditch and apply it deeply, and the depth of the ditch should be as deep as 10cm. Only in this way can we reduce the volatilization rate of nitrogen, keep the fertilizer in a humid environment, improve the conversion rate of fertilizer, and promote the absorption of nutrients in the soil.

4. Fertilization location

The location of fertilization has a great influence on the growth of wheat, and we should keep a certain distance from wheat when applying fertilizer. Because fertilizer is rich in nutrients, moisture absorption capacity is very strong, if fertilization is too close, it is easy to burn wheat plants, produce fertilizer damage, harm the growth of wheat, can not successfully survive the winter. Therefore, when applying fertilizer, we should prevent fertilizer from touching the roots of wheat and not touching new leaves to prevent burning roots and leaves. The method of deep application of ditch is a very good fertilization method, which can not only improve the fertilizer conversion rate, but also prevent the above problems.

The above is a brief introduction to the matters needing attention in winter fertilization for wheat, especially in the use of urea, we should pay more attention to the fact that it should not be watered before urea is applied, because watering before urea is completely decomposed will cause the loss of urea and lead to waste of fertilizer.
