我县从1977年开始进行黄麻育苗移栽,1978年移栽面积550亩。1978年育苗移栽12个点的平均单产达681.3斤,其中最高的达982.6斤,比直播麻多收382斤。黄麻育苗移栽的好处是:(1)迟麻变早麻,晚茬变早茬。我县黄麻的适宜播种期一般在4月上旬至5月上旬,而前茬作物元麦、小麦的收割往往要拖到5月下旬到6月上、中旬,收麦后播黄麻,比适期播种要迟1个月左右。育苗移栽可提前在5月上旬播种,6月上旬移栽。(3)省种省肥。育苗移栽的黄麻每亩只需种子0.5斤左右,仅为直播麻的四分之一左右。直播麻苗期一般追肥1—2次,育苗移栽的苗床面积为大田面积的六分之一,节省苗期用肥约三分之一。(3)能错开
County since 1977, jute transplanting transplanting area of 550 acres. In 1978, the average yield of transplanting 12 points reached 681.3 kg, the highest of which reached 982.6 kg, which was 382 kg more than that of direct seeding. The benefits of transplanting jute nursery stock is: (1) early hemp mutagenesis, early crop stubble change stubble. Suitable for sowing jute my county generally in early April to early May, and the former crop of wheat, wheat harvest tend to be dragged from late May to June, mid-harvest wheat, after the broadcast jute, than the appropriate period Seeding should be about 1 month later. Seedling transplanting can be planted early in May in early June transplanting. (3) provincial species and fertilizer. Seedlings transplanted jute just 0.5 pounds per acre seed only about a quarter of broadcast linen. Seeding broadcast seedling general top-1-2 times, nursery transplanting seedbed area of one-sixth of the area of ?? the field, saving seedling with about one-third of fertilizer. (3) can be staggered
