摘要
试验表明，适当深耕、育苗移栽、地膜覆盖和坐水播种等农业措施，均能提高盐碱地甜菜的保苗率，秋耕深度以４０ｃｍ为好；纸筒育苗移栽或“切块”移栽均能达到抗耐盐目的，以４叶期或６叶期移栽为好。地膜覆盖较非盐碱地露地栽培块根产量平均增产１１２％。盐碱地坐水播种可提高幼苗耐盐能力，一般应灌水两次。
The test results showed that these agriculture measures could promotingt the sugarbeetestablishment with optimum autumn deep ploughing,pper-pot culture, covering with plastic andsowing with water on alkaline souil.The autumn deep ploughing with 40cm was the best,trans-planted with paper-pot culture and “cut into pieces”culture could promot the establishment,andat 4 or 6 leaf stage was the best for transplanting,It could inerease the toot yield 112% with plas-tic covered than that of over-wintrerd culture on the other land.Sowing with water couldinerease the ability of tolerance to saline,it was necessaty for watering 1～2 times aftersowing.
