今年,我校引入油菜高产品种“三月黄”,在校内学农基地试种4.7亩,平均亩产361斤。在校外教学基点平罗公社西二台子大队实验田里种植8.5亩,平均亩产349斤。均比“门源”油菜(平均亩产120斤)显著高产。三月黄油菜的生育表现:①生长期较长,我校于3月12日播种,4月13日出苗,7月5日收获;西二台子大队于3月14日播种,4月13日出苗,7月3日收获,比“门源”油菜晚7～10天。今年气温较低,如在正常气温条件下,估计三月黄可在6月下旬成熟。②营养生长时间长,营养体发达,5片真叶开始现蕾。叶片肥大,单株叶
This year, our school introduced the rapeseed high-yielding variety “March yellow”, and cultivated 4.7-hectare base in the school-farming base, with an average yield of 361 kg per mu. Outside the teaching base Ping Luo commune Xierzizi Brigade experimental field planting 8.5 acres, the average yield 349 pounds. Than the “source” rape (average 120 kg per mu) significantly higher yield. March yellow rape’s reproductive performance: ① longer growing period, my school sown on March 12, April 13 emergence, harvest on July 5; West Taiwan Erzi Brigade sown on March 14, April 13 Emergence, July 3 harvest, than the “source” rape 7 to 10 days later. This year the temperature is low, as in the normal temperature conditions, it is estimated March yellow can mature in late June. ② long vegetative growth, nutrition body developed, 5 true leaves began to bud.
