What are the precautions for fertilizing wheat in winter?
Wheat is divided into winter wheat and spring wheat, and now that winter has arrived, what is planted is naturally winter wheat. When planting winter wheat, it is also necessary to do a good job of fertilizing. Fertilizing winter wheat is a key measure to ensure that the wheat successfully overwinters, but fertilizing winter wheat is different from fertilizing spring wheat. There are many aspects 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. We must first apply sufficient base fertilizer, which is mainly fully decomposed farmyard manure. Then during the planting period, we should topdress in a timely manner according to the soil fertility, the growth of the wheat and the past yield of the plot. For example, for plots with low to medium past wheat yields, the amount of topdressing should be increased, which is of great help to the growth of wheat and can effectively increase wheat yield. Conversely, for fields with higher yields, the amount of fertilizer can be appropriately reduced. The amount of fertilizer must not be too much, to prevent fertilizer damage to the wheat and affect wheat growth.
2. Comprehensive nutrition
The nutritional needs of wheat growth are relatively comprehensive. When fertilizing, we should adjust the nutrient ratio in the fertilizer well and must not apply a single type of fertilizer for a long time. Ensure the diversity of fertilizers. And 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 the utilization rate of fertilizer. 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. Deep application in furrows
Many farmers apply fertilizer, especially urea, to the soil surface when fertilizing. In this way, 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 the growth of wheat. Therefore, when applying urea, we should try to open furrows and apply it deeply, and the depth of the furrow must be no less than 10cm. Only in this way can the volatilization rate of nitrogen be reduced, the fertilizer be kept in a moist environment, the fertilizer conversion rate be improved, and the absorption of soil nutrients be promoted.
4. Fertilization position
The fertilization position has a great impact on the growth of wheat. When fertilizing, we should 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 can easily burn the wheat plants, cause fertilizer damage, harm wheat growth, and prevent successful overwintering. Therefore, when fertilizing, we must prevent the fertilizer from contacting the wheat roots, and it must not touch the new leaves either, to prevent root burn and leaf burn. The method of deep application in furrows 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. Do not water when applying urea, because watering before the urea has completely decomposed will cause the loss of urea and lead to fertilizer waste. That is all for today's introduction.
