Reasons and solutions for peanut shells
Recently, novice growers and friends have consulted the peanuts that have been painstakingly planted. What are the shells? What caused it? In fact, the main reason for the empty shell of peanuts is due to calcium deficiency, and the reason for calcium deficiency is mainly due to the following:
First, the reason for peanut shell
1. Excessive phosphorus and potassium
If the phosphorus fertilizer is applied too much during the peanut planting process, it will cause the combination of phosphate ions and calcium ions, thus affecting the absorption of calcium. Similarly, excessive application of potassium fertilizer will also affect the absorption of calcium by peanut roots.
2. Soil causes
In general, active calcium in acidic soils is particularly prone to loss, so if it encounters the rainy season, it will directly manifest as calcium deficiency, and calcium fertilizer must be added in time. There is also the accumulation of water in the soil or drought will affect the absorption of calcium in peanut roots. That is to say, the peanuts are planted in the sand or the land with poor water retention capacity, the organic matter content is small, and the empty shell rate is higher.
Second, the solution of peanut shell
1. Water management
Everyone should do a good job of water management and open a drainage ditch. If there is too much rainfall, the accumulated water can be drained in time to avoid the loss of calcium ions in the soil. If the weather is dry, it should be watered in time to promote the absorption of calcium by the roots.
2. Supplement calcium fertilizer
Calcium superphosphate can increase the calcium content in the planted soil. Usually, 30 to 50 kilograms of superphosphate is applied as the base fertilizer in the next mu. If you want to promote the absorption of calcium by the peanut roots, you can add two pounds of borax. . In areas with excessive calcium deficiency, calcium sulfate can also be applied in an appropriate amount during flowering.
3. Fertile soil
Peanuts should be planted in fertile soil to increase the spread of organic and calcium fertilizers, providing soil with various elements and improving soil quality. For some acidic soils, quicklime can be used for neutralization.
The above is the reason and solution for the peanut shell. If you are also experiencing this phenomenon, come see if there are any reasons, if there is no way to share the experience to more people.
