Many farmers are aware of the need to apply nitrogen, phosphorus, potassium, and other fertilizers to grow wheat. The higher the production requirement, the greater the amount of nutrients the wheat absorbs. Therefore, scientific fertilization has become the key to increasing yield and income of modern wheat. In order to help farmers grasp the key points of wheat fertilization, many regions currently use soil nutrient speedometers to test the soil. Under the premise of investigating the soil nutrients, combined with the actual need for fertilization of wheat growth and development, we can achieve a multiplier effect. Effect, realize the goal of increasing fertilizer efficiency, increasing production and increasing quality.
In general, wheat has different nutrient uptake and proportion at different growth stages. For example, in the stage of emergence and jointing, the nitrogen absorbed by wheat accounted for about 40% of the total nitrogen. From the jointing stage to the flowering stage of the booting stage, the absorbed nitrogen accounted for about 30%-40% of the total nitrogen, and there was still a small amount of absorption after flowering. The absorption of phosphorus and potassium by wheat accounted for about 30% of the total absorption during the tillering period. The absorption rate increased sharply after jointing; the absorption of phosphorus increased from booting to maturity, accounting for about 40% of the total absorption. Left and right; potassium absorption from jointing to booting, flowering period is the most, accounting for about 60% of the total absorption, to the absorption of potassium when flowering is the largest.
Therefore, in the different stages of wheat growth, in addition to ensuring the nutrient supply of wheat growth and development, we should also pay attention to the balance of soil nutrients. The application of soil nutrient quickness tester to soil nutrient detection can not only help farmers find the profit and loss of soil nutrients in time, but also can guide the scientific and accurate fertilization operations to maintain adequate nitrogen nutrition in the key stages of wheat growth. And a certain amount of phosphorus, potassium fertilizer, promote early seedling emergence, early rooting of wheat seedlings, cultivating strong seedlings, promote the transformation and transportation of photosynthetic products, promote grain filling and increase grain weight. It lays a solid foundation for realizing the high yield of wheat harvest in all regions. Therefore, scientific agricultural instruments, such as soil nutrient measuring instruments, are becoming more and more popular in modern agricultural production activities and have been highly praised by farmers.
