After the spring peanuts are planted, the seedlings often appear to be rotten. The severe rotting rate is up to 20%, resulting in varying degrees of seedlings and ridges. The causes and preventive measures of rotten seedlings are described below: Rotten species Poor seed quality, improper storage, and long storage period; low-lying terrain, high soil moisture content, heavy soil viscosity, and long seedling emergence times; false soil preparation, affecting seed water absorption, weak seedlings; no select seeds, no size Even, the seeding is not fine or varies in depth, resulting in uneven seedlings or lack of seedlings and ridges; continuous cropping for many years does not change the seedlings, serious seedling disease occurs, resulting in lack of seedlings and ridges; the application of inadequate organic fertilizer or fertilizer concentration is too high Caused by fertilizers, affecting the emergence; after sowing, the weather was hot and cold, causing germination and seedling slow and bad species. Precaution Fine selection of new peanut seeds, seed drying before sowing, improve seed water absorption capacity. The shells were peeled 1-3 days before sowing. The seeds that were not damaged and the germination was not germinated were sown. New high fat film powder with 0.1% seed dressing is used for seed dressing to prevent diseases at the seedling stage. At the same time, 40% phoxim EC was blended at 0.2% of seed weight to control underground pests. Fine sowing depth of 4-6 cm, to avoid direct contact with the seed and fertilizer. The mulching film is covered with mulching film, which can increase the ground temperature by 2°C-3°C. After sowing, the seeds germinate and emerge quickly, which can reduce the incidence.
