我县北部地区是油菜主产区。如1979和1985年种植面积分别占全县的37.27%和58.3%,产量分别占24.6%和49.5%。可见全县种植面积能否稳定,产量是否增大,关键在于北部地区。但北部地区丘陵起伏,土壤粘性重,耕地相对较多,如采用习惯育苗移栽法,有两个问题不好解决:第一,苗田难选。油菜育苗要求土壤疏松、靠近水源,北部地区只有旱田较疏松,而旱田不靠水口,靠水口又无旱田,于是在水口稻茬田上勉强育苗,出苗不齐,保不住面积。第二,油稻麦争工。油菜育苗于9月上旬播种,中下旬需管理,这时正值中熟稻抢收季节,顾了收顾
The northern part of our county is the main producing area of rape. For example, the area planted in 1979 and 1985 accounted for 37.27% and 58.3% of the county respectively, accounting for 24.6% and 49.5% of the total respectively. Can be seen throughout the county planting area is stable, the output is increased, the key lies in the northern region. However, there are two problems in the northern region, such as undulating hills, heavy soil stickiness and relatively heavy cultivated land. Rapeseed nursery requires loose soil, close to the water, the northern region is only loose than the dry field, and dry fields do not rely on the outlet, no water by the dry field, so barely fertile seedlings in the rice fields on the outlet, sprouting, can not keep the area. Second, oil and wheat fight workers. Rapeseed nursery sowing in early September, in late to be managed, when the value of cooked rice harvest season, taking care of
