在研究总结油莱以防冻保苗为主的综合丰产栽培技术的基础上,为了进一步提高油莱单位面积产量,1983—1984年,我们在河南省组织有关单位协作,对高产油莱产量结构与生长发育特点进行了研究。一、高产油菜的产量结构各点试验地面积2亩左右,亩施基肥土杂肥3000斤,碳酸氢铵60斤,过磷酸钙80斤,追肥尿素60斤,供试品种为甘兰型油菜开封矮选。平均亩产371.9斤,其中有2.78亩,平均亩产达471.4斤(见表1)。表1表明:在相同施肥水平条件下,油菜
In order to further improve the yield per unit area of oilseed rape, based on the research on the comprehensive high-yielding cultivation techniques of oilleaf to protect frost and seedlings, we organized the cooperation of relevant units in Henan Province from 1983 to 1984 to study the yield structure and growth of high- Developmental characteristics were studied. First, the yield structure of high yield rapeseed Each test area of about 2 acres, Mushi base fertilizer mixed fertilizer 3000 kg, ammonium bicarbonate 60 kg, 80 kg of superphosphate, urea 60 kg top-dressing test varieties for the type of Brassica napus Kaifeng short selection. The average yield of 371.9 kg per mu, of which 2.78 acres, an average of 471.4 pounds per mu (see Table 1). Table 1 shows that rape under the same fertilization level
