草木樨人工草地的建植与利用技术

The Establishment and Utilization Technics of Melilotus albus Sown-Pasture

在德令哈地区选择含盐量低于０．５６％，且具备灌溉条件的盐碱地建立草木樨人工草地。种植前一年夏季深翻，１０月份灌足冬水；４月播种，若灌溉条件好，可推迟到６月初，配合使用除草剂控制杂草的危害；每年４、８、１０月各灌水一次；建植第一年不放牧。收获期以７月下旬现雷一初花期为好，每公顷风干草产量达１４８９３ｋｓ。晒制的青干草可用于牛羊等的育肥和补饲，加工的草粉可作喂猪的饲料。

The low saline(salinity 0. 56%)and irrigable saline-alkali-lands in Delinhaarea were selected to establish Melilotuts pasture. The land was deeply plowed one yest beforesowing and well lrrigated in October. April was the best time for sowing(sowing time couldbe postponed to July if irrigation condition was good). Weeds could be effectively controlledby applying herbicide.The sown pasture was irrigated in April,August,October respectivelyeach year. It was not grazed in the year of sowing.The reasonable harvest period is the end ofJuly(from but to early flowering),and a hay yield of 14 893kg/hm￣2,Could be get at thistime.The hay can be used to fatten sheep and cattle,feed pig,or supplement.
