阳高县是山西省甜菜主要产区之一,传统的甜菜播种方式是穴种,但穴种甜菜出苗缺窝多、高青顶比例增大等现象越来越突出。针对这些问题,1988～1989年进行了专门试验。综合总结出“甜菜深种浅盖分层培土”的措施,1990年开始大面积示范,一取得了较好的效果。两年小区试验均设在阳高夏家场村和青顺堡村。试验地为栗钙土,肥力中等,墒情一般,前茬为玉米、山药,4年轮作,亩施过磷酸钙50kg。试验采用随机区组设计,4次重复,6行区,行长15m,行株距50cm×28cm,供试品种为晋甜一号。试验设3个处理:1、常规穴种(CK),播深3cm,覆土3cm;2、深种6～7cm,浅盖土3cm,1对真叶后根据生长情况分层培土,
Yanggao County is one of the main sugarbeet producing areas in Shanxi Province. The traditional sugar beet sowing method is a kind of hole species, but the phenomenon of the emergence of a lot of bee species in the hole and the increase of the proportion of high green tops becomes more and more prominent. In response to these problems, 1988 ~ 1989 conducted a special test. Comprehensive summed up the “deep beet shallow cover layered soil” measures, large-scale demonstration started in 1990, one achieved good results. Two years plot test are located in Yang Gao Xia Jia Chang village and the village of Fortune. Test for the chestnut soil, medium fertility, soil moisture in general, the former crop of corn, yam, 4-year rotation, Mushi Shi calcium phosphate 50kg. Randomized block design was used in the experiment. Four replicates were used. In the 6-row area, the governor was 15m long and the plant spacing was 50cm × 28cm. The tested cultivar was Jintian-1. The experimental set of three treatments: 1, the conventional point species (CK), sowing depth 3cm, casing 3cm; 2, deep species 6 ~ 7cm, shallow cover soil 3cm, 1 pairs of true leaves according to the growth of layered soil,
