How should peanuts be planted to achieve high yields?
Prepare a plot of sandy soil with sufficient fertility, and deep plow it and apply plenty of base fertilizer. Then select plump, healthy seeds, dig holes at a row spacing of 40*20cm, plant three or four seeds in each hole, finally cover with soil, scatter a thin layer of fertilizer, and cover with plastic film. After seedlings emerge, thin and fill in the seedlings promptly, and carry out basic management work such as fertilizer and water management and pest and disease control, and you can achieve a high yield.
High-yield peanut planting and management techniques:
1. Intertillage and earthing up
During the planting process, we should carry out appropriate intertillage and earthing up of the soil according to the looseness of the soil and the growth rate of the plants. Intertillage can make the soil looser, improve soil permeability, strengthen root respiration, make nutrient absorption more comprehensive, and promote peanut growth. Proper earthing up can effectively keep warmth and retain water, prevent waterlogging, and because peanut fruits grow underground, it can also promote pod development and ensure yield. The height of earthing up should not be too high, otherwise it will delay fruit ripening time.
2. Applying foliar fertilizer
Foliar fertilizer is very important for peanuts. Foliar fertilizer can not only provide water for leaf growth, but also promote leaf growth speed, strengthen photosynthesis, and increase nutrient accumulation in the plant. However, foliar fertilizer should not be applied blindly. Improper use may make the leaves too large, affect the plant's light exposure, and instead have a certain impact on plant growth. The most suitable time to apply foliar fertilizer is during the peanut pod-setting stage. This stage is when the peanut root capacity is weakest, so we should apply some foliar fertilizer to supplement the plant's nutrients.
3. Water management
Peanut water demand has certain stages. Before the flowering and pegging stage, the water demand is not large, but when this stage is reached, its water demand gradually increases. We should water promptly to supplement water, ensure plant growth, and must not let the plant be in a drought environment. However, also note that there should be no standing water in the field, and standing water should be drained promptly, otherwise standing water will affect root respiration and may even cause root rot. Therefore, while ensuring that the soil is moist, also prevent excessive standing water from causing soil compaction.
4. Controlling top growth and promoting underground development
The pod-setting stage is one of the most important periods in the entire growth process of peanuts, and it is also the stage when peanut plants grow fastest. Therefore, the demand for nutrients will also gradually increase. If the nutrients required by the plant are not met at this stage, it will have a great impact on plant growth and pod plumpness. However, also note that excessive fertilization should not be applied. Excessive nutrients will cause the plant to start excessive vegetative growth, which not only affects field permeability, but also causes the phenomenon of flowering without fruiting. This reduces yield and affects farmers' planting benefits.
The above is the relevant introduction on how to plant peanuts to achieve high yields. I hope it is helpful to everyone.
