The invention discloses a rice and wheat
drill sowing under-
mulch drip irrigation cultivation method. The method comprises the steps of seed preparation,
land preparation, belt type
drill sowing,
seedling management,
irrigation management, fertilization management and
disease control. According to the belt type
drill sowing, drill sowing,
drip irrigation belt laying, bubble film covering and soilcovering manners are adopted for sowing, the drill sowing adopts alternate configuration of wide rows and narrow rows, and
drip irrigation belts are laid in the wide rows; the wide rows, the sowing width and the narrow rows are combined into drill sowing belts, the upper portions and the side edges of bubble films are covered with soil, and the plurality of drill sowing belts are planted below each bubble film; and coleophyllum pierces the bubble films in a seed needle erecting period, so that self-film-breaking
seedling emergence is realized. According to the rice and wheat drill sowing under-
mulch drip
irrigation cultivation method, the cultivation method combining drill sowing, bubble film covering and under-film drip
irrigation is adopted, incisions or holes are not formed in the films, the coleophyllum is used for breaking the films in the needle erecting period, in-hole weeding is avoided due to the fact that
seedling holes are not formed, temperature increasing, soil
moisture conservation and
drought resistance are achieved, labor is saved, and cost is reduced; and a rice and wheat under-film drip irrigation cultivation technology is optimized and perfected through drill sowing, so that the agricultural planting efficiency is improved, and the rice and wheat yield and quality are improved.
