How to manage peanuts during the flowering and podding stage? Latest technical key points

Peanut is a grain crop that many people enjoy eating very much, and it is also a relatively important oil crop in our country. It has a very large planting area in our country. When planting peanuts, we should pay attention to carrying out management work well according to the growth stages of peanuts. This is especially important during the flowering and podding stage of peanuts. So how should peanuts be managed during the flowering and podding stage? Let us take a look together below!

1. Drought resistance and seedling protection

Although peanuts have relatively strong drought tolerance, if the soil moisture is insufficient during the critical period when water is needed, then the growth of peanuts will be inhibited, affecting their flowering and podding. When the soil is too dry, the flowering rate of peanuts will drop significantly, and in severe cases flowering will stop. Moreover, the pegs in the soil cannot expand normally, affecting fruit development. Therefore, if the soil moisture content is insufficient, then watering must be done in time, mainly by sprinkler irrigation. This can save water and also ensure that water can smoothly infiltrate into the soil.

2. Foliar topdressing

After peanut seeds are sown, the nutrients originally stored will be completely consumed about one week after emergence. At this time, the seedling roots do not have sufficient nutrients to supply the growth and development of the peanut. It will also affect the reproduction of rhizobia in the roots. In addition, the peanut plants are at this time in a critical period of branching and leaf growth and flower bud differentiation, which likewise requires a large amount of nutrients. Therefore, after peanuts enter the flowering stage, the demand for fertilizer will further increase, and attention should be paid to supplementing nutrition, mainly through foliar topdressing, with fertilizers such as potassium dihydrogen phosphate as the main type.

3. Intertillage and weeding

After peanuts enter the flowering stage, we should also pay attention to carrying out intertillage and weeding work well. The main purpose of intertillage is to improve soil permeability, loosen the soil, promote the growth of peanut roots and nutrient absorption, and provide protection for peanut flowering and podding. It is also very beneficial for peanut peg penetration into the soil and can increase the podding range and yield of peanuts. During intertillage, we should also do a good job of weeding to avoid excessive weeds in the field causing the loss of too many unnecessary nutrients and reducing the peanut flowering and podding rate.

4. Pest and disease control

During the flowering and podding stage of peanuts, pest and disease control work is also very important. Pests and diseases can have a great impact on peanut flowering and podding. Among them, common pests and diseases during the peanut flowering and podding stage include leaf spot disease, stem rot, cotton bollworm, and others. The main targets of damage from these pests and diseases are mostly peanut stems, leaves, and fruits. Therefore, everyone must pay close attention. Different pests and diseases should be controlled with different pesticides. For example, leaf spot disease is generally treated with carbendazim or mancozeb, while stem rot is mainly treated with root-benefiting agents or copper acetate.

The above is a brief introduction to how peanuts should be managed during the flowering and podding stage. That is all for today's introduction. This article is for reference only. We hope it can help everyone!
