Early sowing method of peanut seedlings

Abstract

The invention provides an early sowing method of peanut seedlings. The method comprises the following steps of (1) seed selection, wherein after seed drying with shells, shelling is conducted, and seeds with full seed kernels, uniform sizes and normal seed coat colors are selected; (2) seed soaking and germination accelerating, wherein the seeds are put into a constant-temperature soaking solutionat 50 DEG C for seed soaking, the soaked seeds are put into a plastic basin, the plastic basin is covered with wet cloth or a towel, water spraying and humidifying are conducted, and the plastic basin is put into a constant-temperature box for germination accelerating; and (3) seedling transplanting, wherein organic nutrient soil is laid in a lattice seedling tray, germinated seeds are inserted into the lattice seedling tray with teeth facing downwards, the lattice seedling tray is covered with the organic nutrient soil, water spraying and humidifying are conducted, the whole lattice seedlingtray is put into a greenhouse for seedling, a film arch cover is added, film uncovering and seedling hardening are gradually conducted 8 days after seedling emergence, and when 2-3 true leaves grow out of seedlings, the seedlings are transplanted to a field in rainy days or at dusk. According to the early sowing method, through germination accelerating, seedling growing and transplanting, peanutseeds can be saved, the growth process is advanced, the yield is increased by 20% or above, the peanut marketing time can be advanced, and economic value is created.

Description

technical field [0001] The invention belongs to the technical field of peanut planting, and in particular relates to a method for early sowing of peanut seedlings. Background technique [0002] Peanut is an important economic crop and oil crop, and the development of peanut production has become one of the important ways to increase agricultural efficiency and farmers' income. Peanut is a kind of nut with abundant production and wide consumption in our country, also known as "longevity fruit" and "groundnut". [0003] In recent years, with the improvement of people's living standards, edible vegetable oil has been favored, and the planting area has increased year by year. The traditional cultivation method is to plant the peanut kernels in the soil after peeling the shells by hand, often burning the seeds with fertilizers, waterlogging and other reasons, resulting in uneven emergence of seedlings and affecting the yield. Emergence is uneven, and secondary replanting is req...
