What is the best way to apply fertilizer during grape growing?
Selection and application of chemical fertilizers.
Nitrogen is the main nutrient that affects the growth and development of grapes, especially in the expansion period, and proper application of nitrogen is of great significance to promote fruit expansion and increase yield. When applying nitrogen, care should be taken to apply inorganic or inorganic nitrogen.
Organic nitrogen (including organic fertilizer) is a natural nitrogen** that can be combined with organic matter and plays an important role in improving and maintaining the ecological environment of farmland. Organic nitrogen is an effective means of strong slow-release and continuous supply of nitrogen, which improves soil fertility and maintains a better soil structure. The results showed that during the fruit development stage, the appropriate application of chemical fertilizer could not only ensure the requirement of fruit nutrition, but also reduce the loss of nitrogen.
Fertilizers, such as urea, are quickly absorbed and utilized by the roots of the grapes and provide nutrients for the normal growth of the grapes. Urea has the characteristics of high nitrogen fertilizer use efficiency, high fertilizer utilization rate, easy storage and easy promotion. The results showed that the application of appropriate fertilizers during the growing season quickly met the nutrient needs of the grapes and allowed them to swell.
At the fruit development stage, in addition to selecting the appropriate nitrogen application rate, nitrogen should also be applied according to the local area. In production practice, it is necessary to scientifically and appropriately adjust the amount of fertilizer according to the actual situation to prevent excessive plant flourishing caused by excessive application, thereby reducing the quality and yield of fruits. In addition, it is necessary to allocate the nitrogen in a reasonable period, generally speaking, during the grape expansion period, the nitrogen is used a little earlier and then gradually reduced in the later stage.
Selection and application of chemical fertilizers.
Phosphorus is the main nutrient that affects the growth and development of grapes and the accumulation of carbohydrates. The results showed that in the late growth stage, the application of appropriate P fertilizer could accelerate the swelling and promote the accumulation of carbohydrates, thereby improving fruit quality and yield.
Therefore, the rational selection of different types of phosphorus is very important for the efficient use of phosphorus. Triammonium phosphate and triammonium phosphate are commonly used fertilizers that are quickly absorbed by the roots of grapes. These two kinds have high phosphorus content and significant fertilizer effect, which can quickly meet the needs of P in the later stage of grape growth. In addition, in order to adapt to the phosphorus needs of grapes, compound fertilizers or organic fertilizers containing P can also be used.
When applying phosphorus, phosphorus should be applied appropriately to avoid a large amount of phosphorus accumulation and a large amount of waste. In the process of fertilization, the amount of phosphorus should be reasonably adjusted in combination with the production conditions and soil phosphorus status to prevent phosphorus deficiency or excess. In addition, the timing of fertilization should also be grasped well, usually early in the ripening period to ensure the growth of the fruit.
b.Potassium is used selectively.
Potassium is a key nutrient that affects the growth and development of grapes and the accumulation of carbohydrates. The results showed that in the late growth stage, the application of appropriate potassium application could make it expand and increase the sugar content, thereby improving the quality and yield.
Choosing the appropriate amount of potassium is a key factor affecting the normal growth and development of grapes. Potassium and potassium are commonly used as chemical sources of potassium, which are rich in potassium and can be quickly absorbed by grape roots. Both of them contained high potassium nutrients, which had significant effects on fruit growth and sugar accumulation. In the later stages of growth, potassium or sulphate can be added to meet the needs of the grapes for potassium.
In addition, potassium should be applied moderately when applying potassium to avoid potassium accumulation and waste of chemical fertilizer. The amount of fertilization should be adapted to the growth and development of grapes and the potassium status of the soil. In addition, since the potassium requirement of the grapes tends to increase during the expansion process, it is necessary to delay the potassium requirement as much as possible when properly dressing them.
Addition and application of trace elements.
In the late stage of growth, in addition to the supplement of nutrients such as N, P, and K, it is necessary to strengthen the supplementation and utilization of nutrients. In the process of growth and development, the supply of trace elements such as zinc, manganese, and iron is needed to enable them to grow and maintain nutritional balance. To provide nutrients to your grapes, you can use a combination of chemical fertilizers or special micronutrient fertilizers. This product is a multi-element integration that can meet the nutritional needs of grapes in an all-round way.
The special trace element fertilizer is even more accurate to the extreme, and can be accurately fertilized according to the needs of different varieties. Through the soil culture test of different varieties, combined with the conditions of the grapes themselves, the appropriate fertilization types and fertilization methods were reasonably selected. In addition, when using trace element fertilizers, they should also be applied appropriately to avoid excessive accumulation of nutrients. Although there are very few micronutrients in the soil, the amount of fertilizer applied should be properly controlled in order to ensure nutrient balance.
The conclusion is that during the fruit development period, the appropriate amount of N, P, K and trace elements should be paid attention to when fertilizing. Nitrogen application can make the fruit swell and increase the yield, p can increase the glucose accumulation, and potassium can increase the sugar content of the fruit. Appropriate addition of trace elements can ensure its growth and development, and make the nutrition balanced. When applying chemical fertilizers, it is necessary to combine the specific local conditions, combined with the specific local conditions, and appropriately adjust them to prevent the excessive application of chemical fertilizers and the waste of chemical fertilizers. It is advisable to conduct a soil test before applying a chemical fertilizer to determine its nutritional status and pH so that the appropriate fertilizer can be selected in a targeted manner. Scientific and rational application of fertilizer is an important way to ensure the growth of grapes and improve yield.
