Applying Fertilizer to Plant High-yielding Base of Winter Wheat
October 8 was "cold dew," and the weather turned cold from cool to cool. The sowing of winter wheat is an important farming activity in this climate. In order to ensure the safe wintering of winter wheat and the successful return of green crops to lay a foundation for high yields, it is only necessary to seize the basic link of sowing to cultivate a group of wheat seedlings that are neat, robust, and resistant. For this reason, the application of seed fertilizer is a key measure with obvious and feasible results.
The high yield of winter wheat cannot be ignored. The role of seed fertilizer is to provide the necessary nutrients for the wheat seedlings. When the seedlings first came out, the roots developed weakly and the ability to absorb fertilizer and water was poor. However, when the winter wheat was planted in vast northern wheat areas, the soil temperature was already low, and the nutrients released from the soil itself were slow, and it was very likely that there was no supply. The winter wheat seedlings, although few in terms of nutrient requirements, are sensitive and strict and need to provide less nutritious nutrition. Therefore, the role of seed fertilizer is to ensure that the wheat seedlings are strong, they can pass through winter and return to green in time. This is one of the keys to the high yield of winter wheat. At this time, fine application of seed fertilizer can improve the ability of wheat seedlings to resist drought and resist cold and achieve the purpose of cultivating strong seedlings.
Fertilizer applied fertilizer? Fertilizer is the most needed fertilizer. Wheat seedlings are very urgent for phosphate fertilizers, and they are very sensitive to phosphate fertilizers. If phosphorus deficiency or severe phosphorus deficiency occurs at this time, weak seedlings and seedlings will appear to be missing. In the case of drought and cold, there is the problem of frozen dead seedlings; after the seedling period, even if additional phosphate fertilizer is applied later, it will not be able to make up for the loss caused by this time. Therefore, the appropriate nutrient ratio for seed fertilizer is mainly phosphorus, with a small amount of nitrogen. Fertilizer varieties can be compound fertilizer or single fertilizer. For example, diammonium phosphate is commonly used in the northwestern and northern wheat areas, and diammonium phosphate and nitrophosphate can be used in binary compound fertilizers; in the middle and lower reaches of the Yangtze River, the most commonly used fertilizer varieties are low in concentration. Calcium phosphate and ammonium sulfate are suitable. Because the appropriate nutrient ratio of fertilizer is less phosphorus and nitrogen, usually do not use high-nitrogen compound fertilizer as seed fertilizer, so as to avoid the problem of seedling sprouting or burning seedlings.
How much fertilizer application is reasonable? The amount of fertilizer can not be used in large quantities, and it is necessary to grasp the principle of less and more refined, and promote the use of precise quantities. Diammonium phosphate is suitable for 5 kg/mu. Although the amount is small, it can play the role of “a couple of thingsâ€; Superphosphate is suitable for 8 kg/mu; ammonium sulfate should not exceed 5 kg/mu.
Finally, the method of application of fertiliser and the location of fertilization are equally important. Regardless of the method of sowing or livestock sowing, the fertiliser can not be directly contacted with the wheat seed, and the fertiliser should be applied 2-3 cm below the slope of the wheat seed. It is safe to separate wheat from conventional fertilizers.
