When planting potatoes, the choice of base fertilizer has a great impact on the growth and yield of potatoes. The base fertilizer should usually be rich in organic matter and provide a variety of nutrients needed for potato growth. Here are some common options for potato base fertilizer:
Farmyard manure: For example, fully decomposed cow manure, pig manure, chicken manure, etc., are good base fertilizers. Not only do they provide abundant nutrients, but they also improve soil structure. Green manure: Turning green manure crops (such as alfalfa, clover, etc.) into the soil can increase the organic matter content of the soil. Commercial organic fertilizerSuch as bio-organic fertilizer, compound organic fertilizer, etc., containing a certain proportion of nitrogen, phosphorus, potassium and trace elements. Chemical fertilizers: Such as urea, superphosphate, potassium sulfate, etc., can quickly replenish the main nutrients needed for plant growth. When applying base fertilizer, the following points should be noted:
Amount of fertilizer: Determine the amount of fertilizer according to soil fertility and target yield to avoid fertilizer damage caused by over-fertilization. Fertilization time: The base fertilizer should be applied before sowing and mixed well with the soil. Fertilization method: After fertilization, it should be deeply turned so that the fertilizer is fully mixed with the soil, which is conducive to the growth and development of potato tubers. The following should also be noted during the sowing process:
Selection: Select healthy, disease-free seed potatoes and apply appropriate germination treatment. Cut into cubes: If using whole seed potatoes, make sure that each seed potato has 1-2 sprout eyes. When cutting and sowing, 1-2 bud eyes should be kept for each cut, and the cut wound should be treated with plant ash or fungicide. Seeding depth: Potatoes should be planted in soft, well-drained soil, generally at a depth of 5-10 cm. Row spacing and plant spacing: Determine the reasonable row spacing and plant spacing according to the variety and soil conditions, the general row spacing is 60-70 cm, and the plant spacing is 25-30 cm. Soil moisture: After sowing, the soil should be kept moist, which is conducive to the germination of seed potatoes and the growth of plants. Pest and disease control: Pay attention to the prevention and control of potato late blight, aphids and other common pests and diseases. Cultivating and weeding: During the growth of potatoes, weeding should be carried out in a timely manner to keep the soil loose and promote root development. Through proper fertilization and careful sowing management, the yield and quality of potatoes can be effectively improved.
