Experiments have been canrried out with bestnitrogen fertilizing amlount on main stages in rape with moden regression method,the results are as fallows:Under 7.skg/mu nitrogen fertilizing level,best ratio of base fertilization,winter fertilization and spring fertilization is 5:3:2。At the same time,the relation ships of nine main characters in rape with the nitrogen fertili- zing amount on main stages were discussed in this paper

应用回归分析方法研究了油菜在亩施7.5公斤纯氮水平下,不同时期施氮的最佳比例,建立了油菜产量的数学模型。在计算机上模拟寻优得出亩产165公斤以上方案38套,分析结果:基肥、苗肥、蕾苔肥三者的最佳比例为5:3:2。本文同时讨论了油菜不同时期施氮比例对6个主要经济性状的影响。

The soil around the Qinshan and Daya Bay nuclear power plants were used in this study. The 90Sr was spread into the soil by irrigation. The amount of 90Sr spread were 0. 037,0. 37,3. 7,37 and 370 Bq per gram soil respectively. After being treated,the soil were employed to grow rice, wheat, rape, bean, asparagus lettuce, tomato and peas. The harvested plants were divided into seeds,stems and leaves,husks and roots to measure their radioactivity separately. The results showed that the amount of 90Sr absorbed...

The soil around the Qinshan and Daya Bay nuclear power plants were used in this study. The 90Sr was spread into the soil by irrigation. The amount of 90Sr spread were 0. 037,0. 37,3. 7,37 and 370 Bq per gram soil respectively. After being treated,the soil were employed to grow rice, wheat, rape, bean, asparagus lettuce, tomato and peas. The harvested plants were divided into seeds,stems and leaves,husks and roots to measure their radioactivity separately. The results showed that the amount of 90Sr absorbed by the plants was directly proportional to the 90Sr content in the soil. The absorbed 90Sr was mainly distributed in the stems and leaves. The seeds absorbed the least amount of 90 Sr compared with the other portions. The old leaves absorbed greater 90Sr than the buds. The accumulated 90Sr per unit dry weight of all plants grown in the soil from Daya Bay area was greater than in the soil from Qinshan area. More than 80% of total 90Sr was distributed in the top layer from 0 to 4 cm. The concentration factors of various plants were also given.

选择了秦山、大亚湾核电站周围具有代表性的农业土壤,随灌水向土壤中施入~(90)Sr,施入量分为每克土含~(90)Sr:0.037Bq,0.37Bq,3.7Bq,37Bq,370Bq。在上述土壤上种植了水稻、春麦、油菜、大豆、莴笋、西红柿、菜豆等,收获后将作物分成:籽粒、茎叶、颖壳、根等几部分并测其放射性,结果表明:进入植物体~(90)Sr的数量与土壤中~(90)Sr的含量呈正比。进入植物体的~(90)Sr主要分布在茎叶部,籽粒部含量最少;老叶中~(90)Sr多于幼嫩叶片。种植在大亚湾土壤上的各种作物单位干重~(90)Sr的积累量均高于秦山土壤上的作物。土壤中的~(90)Sr80%以上分布在0~4cm的表层。文中给出了各种作物在两种土壤上对~(90)Sr的浓缩系数。

A field experiment was conducted during 1988~1989 to study the effect of three tillage methods and four phosphorus fertilization rates on grain yield of rape grown in paddy field after rice.It was found that grain yield of rape was not signifi- cantly affected by tillage but it was significantly affected by phosphorus fertilization rate or phosphorus fertilization rate×tillage method.Under no—tillage practices the ef- fect of phosphorus fertilization to increase grain yield of rape is more...

A field experiment was conducted during 1988~1989 to study the effect of three tillage methods and four phosphorus fertilization rates on grain yield of rape grown in paddy field after rice.It was found that grain yield of rape was not signifi- cantly affected by tillage but it was significantly affected by phosphorus fertilization rate or phosphorus fertilization rate×tillage method.Under no—tillage practices the ef- fect of phosphorus fertilization to increase grain yield of rape is more significant than those under conventional practise.

裂区试验研究了免耕、浅耕和常规翻耕三种耕作法和四种过磷酸钙施用量对稻茬油菜产量的影响.结果表明:耕作法间油菜产量无显著差异,而施磷量间油菜产量差异达极显著,耕作法和施磷量间存在互作关系.在免耕和浅耕条件下施磷的增产效果比常规翻耕条件下要明显得多.
