A Detailed Guide to the Latest Fertilization Timing and Methods for Peanuts
Peanuts are very widely used in our country; they are not only a small snack in our daily lives, but also a basic raw material for our country's edible oil. At present, the peanut planting area in our country is very extensive, and topdressing work is indispensable when growing peanuts. So when should peanuts be fertilized? How exactly should they be fertilized? Below, the editor will introduce them to you one by one. Let's take a look!
1. Seedling stage
During the peanut seedling stage, because its root nodules have not yet fully developed, its demand for nutrients is relatively low. As long as sufficient base fertilizer is applied before sowing, it can meet the nutritional needs for growth, and the growth rate will also increase. At this time, appropriately applying compound fertilizer as topdressing is enough to ensure normal peanut growth, but note that too much phosphorus and potassium fertilizer must not be applied, otherwise it will instead have adverse effects on the seedlings. When fertilizing at the seedling stage, if the base fertilizer is insufficient, then it should be applied promptly before the first flowering, mainly nitrogen fertilizer, with broadcasting and trench application as the main fertilization methods.
2. Flowering stage
The nutritional consumption of peanuts during the flowering stage is relatively large, because during this period the growth direction of peanuts gradually shifts to reproductive growth. Their nutritional demand also increases sharply, so topdressing must be done promptly at this stage to ensure sufficient nutrients to promote peanut flowering. At this time, the proportion of peanut nutritional demand is mainly phosphorus and potassium fertilizer. And because peanuts have nitrogen-fixing ability, appropriately supplementing phosphorus and potassium fertilizer is enough; too much nitrogen fertilizer must not be applied, otherwise it can easily cause excessive vegetative growth in peanuts and reduce yield. In addition, if the peanut flowering rate is found to be low, then it may be caused by boron deficiency, so boron fertilizer should also be appropriately applied as topdressing.
3. Pod-setting stage
When peanuts are in the pod-setting stage, it is the period when the nutrients required for their growth are most vigorous, and their demand and consumption are the greatest throughout the entire growth period. Therefore, at this time, a large amount of nutrients should be supplemented to promote pod growth and increase yield. Topdressing at this stage mainly uses potassium fertilizer, supplemented by nitrogen and phosphorus, to improve the disease resistance of peanuts. Attention should also be paid to the application of trace elements to enhance leaf growth, strengthen leaf photosynthesis, and increase the accumulation of photosynthetic substances. This can both ensure pod growth and prevent premature aging.
4. Maturity stage
After peanut pods gradually mature, the demand for nutrients will also slowly decline, so nutrient absorption capacity will also gradually weaken. However, there will still be a certain demand for nitrogen, phosphorus, and potassium elements; during the maturity stage, the demand for nitrogen fertilizer is relatively high, and rational fertilization can improve the peanut's resistance to pests and diseases. This prevents undesirable phenomena such as empty pods and rotten pods. Foliar nitrogen fertilizer can be appropriately sprayed, and its utilization rate can reach about 60%, which is also very effective in promoting pod maturity. However, care must be taken to control the dosage, and fertilization must not be done blindly, otherwise it is easy to produce the opposite effect.
The above is a brief introduction to the fertilization timing and methods for peanuts. The fertilization work for peanuts is very important throughout their entire growth period. If fertilization is improper, the impact on peanuts may be irreparable. That is all for today's introduction. This article is for reference only. Thank you all for reading and supporting.
