地膜覆盖和纸筒育苗移栽栽培技术已在甜菜生产上广泛应用。为进一步探讨这两项新技术在不同耕作形式下,对甜菜产质量的影响,1987年我们在吉林省扶余县进行了地膜覆盖、纸筒育苗移栽、裸地直播三种栽培方式和畦作三行、大垄双行、垄作单行三种耕作形式的两因素三水平随机区组试验。试验地肥力中等,早春进行“三犁川”整地。结合整地亩施优质农肥3000kg,尿素18kg,磷酸二铵10kg,硫酸钾20kg。6月25日对所有小区亩追尿素15kg。畦作三行亩定苗6250株,大、小行距分别为60cm、30cm,株距为26.7cm。
Film mulching and paper tube seedling transplanting cultivation techniques have been widely used in sugar beet production. In order to further explore the impact of these two new technologies on the yield and quality of sugar beet under different tillage practices, we conducted three kinds of cultivation methods and operations in plastic film mulching, paper tube seedling transplanting and bare soil direct seeding in Fuyu County, Jilin Province in 1987 Three rows, two rows of large ridge, ridge farming three forms of tillage two-factor three-level randomized block test. Fertility test medium, early spring “Sili Sichuan” site preparation. Accompanied by site preparation acres of high-quality agricultural fertilizer 3000kg, urea 18kg, diammonium phosphate 10kg, potassium 20kg. June 25 acres of urea recovery of all plot 15kg.畦 for three lines mu Dingmiao 6250, big and small row spacing were 60cm, 30cm, spacing is 26.7cm.
