Key points of peanut cultivation technology

Peanut is an important agricultural crop that is highly favored for its rich nutritional value and wide range of uses. In order to ensure the healthy growth and high yield of peanuts, the correct planting method is crucial. Here are the key points of peanut cultivation technology.

1. Choose good varieties

When choosing varieties, factors such as local climate conditions, soil conditions, planting habits and market demand should be considered comprehensively. Choose varieties with strong disease resistance, good adaptability, high yield and excellent quality: such as Luhua series varieties and Yuhua series varieties.

2. Plot selection

Peanuts have shallow roots and prefer to grow in loose, fertile, well-drained soil. Therefore, when choosing a plot of land, you should choose sandy land with deep soil, fertile soil and good drainage for planting. At the same time, avoid planting peanuts in saline-alkali land , low-lying land, and areas with serious pests and diseases.

3. Sowing time

The sowing time has a great influence on the peanut yield. Generally speaking, spring peanuts are best sown in late April to early May, and summer peanuts are best sown in early to mid-June. Under suitable environmental conditions, the earlier the sowing, the higher the yield.

4. Sowing method

There are two methods for sowing peanuts, one of which is row sowing. One method is to spread the seeds evenly in the ditch according to a certain row spacing and plant spacing, and then cover them with soil to press them down; the other method is hole sowing, which is to dig holes according to a certain row spacing and plant spacing, put the seeds in the holes, and then cover them with soil to press them down. When choosing a sowing method, it should be decided based on the characteristics of the plot and the characteristics of the variety.

5. Fertilization management

Fertilization is a prerequisite for high peanut yields. Before sowing, apply sufficient base fertilizer, generally 40 to 50 kg of 51% balanced fertilizer per mu. When peanuts enter the early flowering stage, topdressing should be carried out, generally 10 to 15 kg of high-phosphorus and high-potassium compound fertilizer per mu. When applying fertilizer, avoid excessive fertilization and excessive nitrogen fertilizer application, so as to prevent the plants from growing too tall, lodging in the middle and late stages of growth, and serious diseases and insect pests.

6. Prevent and control pests and diseases

Peanuts have many diseases and pests, and the focus should be on preventing root rot, white rot, leaf spot, web spot, aphids and white grubs . When preventing and controlling diseases and insect pests, we must adhere to the principle of "prevention first, integrated control" and adopt a combination of physical control, biological control and chemical control.

7. Harvest in time

When the leaves of the plant turn yellow, the pods become full and the shells become hard, they can be harvested. When harvesting, avoid damaging the pods and plants to avoid affecting yield and quality. After harvest, the peanuts need to be dried and shelled before being sold and stored.

To sum up, the key points of peanut cultivation technology include the selection of good varieties, plot selection, sowing time, sowing methods, etc. Through scientific cultivation and management measures, high-quality and high-yield peanuts can be achieved.
