Paddy no-tillage direct seeding method

Abstract

The invention discloses a paddy no-tillage direct seeding method which is high in paddy scion rate, high in yield, high in milled rice rate, superior in rice quality, and saving in labor, fertilizer and water, and belongs to the technical field of crop culture. According to the method, before the winter solstice, weed killer is sprayed for killing weeds, and the land surface is naturally frozen; weed killer is sprayed again around the tomb-sweeping Day of the next year, and after the weeds are dead, the land is irrigated to keep humidity, and non-grown weeds grow again; weed killer is sprayed the third time around the Beginning of Summer, after the weeds are dead 7 days after weed killer spraying, the land is irrigated continuously for soaking about 6-8 days; seed-corns are soaked in lime water until the seed-corns sprout, then are fished up after being soaked for 10 hours, then rooting powder is mixed with sprouted seed-corns, and after the mixed sprouted seed-corns are aired for 1-3 hours at a shade place, the seed quantity for each mu is 8-10 jin of common variety, and about 3 jin of hybrid seeds; weed killer is sprayed for killing weeds within 1-2 days after sowing in the mode that sealed non-sprouted seeds are made to grow until having 3-4 leaf ages, water in the land is released completely and then the land is sealed to clean the weeds; nitrogen phosphorus and potassium fertilizer is dressed 3-4 days after weed killing; then normal field management period is started.

Description

technical field [0001] The invention discloses a rice planting method, in particular to a no-tillage direct seeding method of rice and belongs to the technical field of crop cultivation. Background technique [0002] No-tillage direct seeding of rice refers to the paddy field that has not been plowed and harrowed after harvesting the previous season’s crop. After the layers are dried naturally and the basal fertilizer is applied, the rice seeds that have been germinated and dewy are directly sown to the field for growth. However, at present, there are the following problems in rice no-tillage direct seeding: rotten seeds or burnt buds usually occur, resulting in lack of seedlings, uneven emergence, early tillering seedlings, tall seedlings, low ear formation rate, and small number of grains per ear, which is easy Problems such as weed damage and lodging occurred, which in turn affected the yield, which brought great troubles to agricultural producers.
