陆稻通常沿用直播栽培,因一般陆稻产区冬春季节干旱,等雨播种,违误农时;播后往往因土壤水分不足和苗期虫害影响,造成缺苗;苗期杂草滋生,除草费工。育苗移栽可弥补上述缺点。育苗方法分常规育苗和隔离层育苗,后者和前者相比,具有根系发育好,秧龄弹性大,耐移栽,拔苗省工,不伤根,可带土移栽,提高成活率,以及适于机插等优点。据我们多年试验及生产示范,平均亩产342公斤,比直播栽培可早播50天以上,增产20%左右。
Upland rice is usually used for direct seeding cultivation, which is caused by drought in winter and spring in general Upland cropping areas and is sowed in rainy season. After sowing, the lack of soil moisture and seedling pests often result in the lack of seedlings. The weeds breeding and weeding Fatigue. Seedling transplanting can make up for the above shortcomings. Compared with the former, the seedling raising method has the advantages of good root system development, large elasticity of seedling age, transplanting and transplanting, pulling the seedling and saving labor, not damaging the root, transplanting the soil and improving the survival rate, and Suitable for machine insertion and other advantages. According to our many years of experiments and production demonstration, the average mu produce 342 kilograms, than direct seeding can be sowed for more than 50 days, an increase of about 20%.
