我们苏北油菜新区,过去对腊肥认识不足,存在着施得迟、施量少、施法粗等方面的问题。针对这种情况,我们对腊肥的施用方法进行了改革,取得了较好的效果。一、施用时间改腊月施为冬前施,以有利于菜苗早得力。我县常年油菜于9月中旬播种,苗龄40多天,10月下旬至11月上旬移栽。我们改为12月中旬施腊肥,施后半个月正值“冬至”前后。在这个阶段,白天(晴天)温度能达到10℃左右,施腊肥后对油菜继续生长和花芽分化有利。据我们1978年调查,在施腊肥后的1个月的时间里,菜苗单株重增加52克,根颈粗增0.7厘米,绿叶增加1片,全田封了行,能安全度过寒冬。
We New North Jiangsu rapeseed area, in the past lack of understanding of wax manure, there are Shi Shi late, Shi Shi less, Coarse law enforcement and other issues. In view of this situation, we have carried out the reform on the application of wax manure and achieved good results. First, the application of change to the twelfth lunar month for the facilities before winter Shi, in order to facilitate early Li Miao seedlings. Perennial rapeseed sowing in mid September, seedling age more than 40 days, late October to early November transplanted. We changed to fertilizers in mid-December, half a month after the application of “winter solstice” before and after. At this stage, the temperature during daytime (sunny day) can reach about 10 ℃. After applying the fertilizer, it is beneficial to continue the growth and flower bud differentiation of the rape. According to our survey in 1978, a month after the application of fertilizers, vegetable seedlings increased by 52 grams per plant, root neck coarse increase of 0.7 cm, an increase of green leaves, the whole field sealed line, can safely survive the winter .
