| 中文摘要: |
| 在旱农区农田生态条件下,采用常规与二次回归正交结合的设计方法,多点同步研究定豌2号高产与密度、氮磷施用量及配比间的关系和相关效应,钼肥、保水剂高效施用技术,并在试验基础上同时进行生产示范验证。根据试验示范结果,选用相应分析程序进行计算机模拟寻优,得到定豌2号产量1 950~2 653 kg/hm2的技术方案65套。该方案95%置信域:播种量109.5~148.5万株/hm2,施N 45~64.5 kg/hm2,P2O5 112.5~147kg/hm2,N∶P2O5约为1∶2.37,沟施植物保水剂7.5 kg,每1 000 g种子用钼酸铵4 g拌种。 |
| 英文摘要: |
| Under dry-farming conditions,quadratic regression and orthogonal design was used to study the correlation effects of density as well as amount and ratio of N and P to yield of Dingwan No.2 in different places,and the effective technologies for applying molybdenum and water absorbant.According to the results of test and demonstration,65 technological schemes were found through computer analysis,in which the yield of Dingwan No.2 reached 1 950～2 653 kg/hm2.The 95% confidence interval of the schemes: seeding rate 109.5×104～148.5×104 grains/hm2;N 45～64.5 kg/hm2,P2O5 112.5～147 kg/hm2,N/P2O5=100/237;ditching water absorbant material 7.5 kg per hm2,ammonium molybdate for seed dressing 4 g/1000g.It is concluded that rational utilization of N(optimization of N and P),seed dressing with ammonium molybdate and proper application of water absorbant are effective ways to improve the production of Dingwan No.2 in dryland. |
