水稻膜下滴灌种植与播种机的研究开发

Rice Drip Irrigation under Plastic Film Cultivation and Research Development of Planter

在优化滴灌水稻种植密度的基础上,提出了水稻膜下滴灌直播技术。同时,根据农艺与农机相结合的要求,研制出了水稻膜下滴灌播种机。通过大面积田间生产考核表明:旱作水稻膜上打孔直播技术,能够大幅减少人工消耗,出苗整齐。生产实践表明,研制的水稻膜下滴灌播种机空穴率≤3%;穴粒数合格率≥85%;膜孔覆土率≥95%;每公顷穴数达到465 000～495 000穴。该机能适应我国干旱区水稻高密度种植农艺技术要求,可为我国干旱区生产稻米提供技术支持。

Use less water, gains more high-quality rice, and improve the level of protection of the national food security. Based on the optimization of drip irrigation in rice planting density, put forward rice drip irrigation under plastic film and direct seeding technology. Developed rice drip irrigation planter, based on agriculture and agriculture machinery. Through a large area field experiment, shows that： the rainfed rice membrane perforated broadcast technology, can significantly reduce artificial consumed and emergence uniformity. Production practice shows that the hole rate ≤ 3 % ; cave grains pass rate≥85% ; the film hole overburden rate ≥95% ; the hole reached 31000-33000 per acres, the machine can a- dapt the arid area of China＇ s rice planting agronomic port for the arid region of china＇s rice produced. technical requirements of high-density, and provide technical sup-
