How to prevent spring peanut rotten

Spring peanuts often rotted before seedlings, and the serious rotten rate reached 20%, resulting in different degrees of seedling rupture.
Causes of rotten seeds, poor seed quality, improper storage and long storage period; low terrain, high soil water content, soil viscosity, long seed emergence time; unsound land preparation, affecting seed water absorption, weak seedling; no selected seeds Uneven size, uneven seeding or different shades, resulting in seedlings or lack of seedlings and ridges; continuous cropping for many years, serious disease at seedling stage, resulting in lack of seedling ridges; application of fully decomposed organic fertilizer or fertilizer Excessive concentration causes fat damage, affecting emergence; low temperature lasts for a long time, causing germination and emergence of sluggish seedlings.
Precautionary measures are carefully selected, new peanut seeds are selected, and the shells are sun-dried before sowing to improve the water absorption capacity of the seeds. The shells were shed for 1-3 days before sowing, and the seeds with large granules were not damaged and the radicles were not germinated. The seeds are seeded and seeded with a new high-fat film powder with a seed weight of 0.1% to prevent seedling diseases. At the same time, mix 40% of the seed weight of 40% phoxim emulsifiable concentrate to control underground pests. Fine sowing, sowing depth of 4-6 cm, to avoid direct contact between seeds and fertilizer. Covered with plastic film mulching, the ground temperature can be increased by 2-3 °C, and the seeds are germinated and emerged quickly after sowing, which can reduce the incidence.
