- 摘要:
- 为了合理调控基肥施用量，促进水稻产量和品质的提升，进而达到节本增效的作用,选取12份黑龙江省第一积温区表现稳定的水稻品种（系），通过设置不施用基肥（DN）和正常施用基肥(NN)两种含氮量差异田块，分别对各水稻品种（系）的产量性状、加工品质及食味品质进行调查分析，明确基肥含氮量差异对参试材料各性状的影响，及参试材料对基肥差异的敏感性。结果表明，与施用基肥相比较，参试材料不施用基肥处理下实测产量均表现为下降趋势，其中20鉴203、20鉴204、20鉴97、20鉴98、松科粳122和松科粳134在不同处理间差异极显著。基肥施用与否对稻米加工品质影响不显著，对水稻籽粒的长宽等也影响较小，但不施氮肥可使蛋白质降低0%~1.2%，使食味值略有升高，会使产量显著下降，因此合理施用氮肥仍是农业生产中最优的选择。相关性分析表明，在DN和NN两种处理下结实率与空瘪粒均表现为极显著负相关，相关系数均为-0.98，食味值与蛋白质和直链淀粉分别表现为极显著负相关和极显著正相关关系。
- Abstract:
- In order to regulate the application rate of base fertilizer reasonably, promote the improvement of rice yield and quality, and thus achieve the effect of cost saving and efficiency increasing. This study selected 12 rice varieties (lines) with stable performance in the first accumulated temperature zone of Heilongjiang Province. By setting up two types of fields with nitrogen content differences, namely do not application of base fertilizer (DN) and normal application of base fertilizer (NN), the yield traits, processing quality, and taste quality of each variety (line) were investigated and analyzed to clarify the impact of nitrogen content differences in base fertilizer on various traits of the experimental materials, as well as the sensitivity of the reference materials to differences in base fertilizer. The results showed that compared with the application of base fertilizer, the measured yield of the 3tested materials without the application of base fertilizer showed a decreasing trend. Among them, there were 3significant differences between the different treatments of 20 Jian 203, 20 Jian 204, 20 Jian 97, 20 Jian 98, Songkegeng 122, and Songkegeng 134. The application of base fertilizer had no significant effect on the processing quality of rice, and had a small impact on the length and width of rice grains. However, not applying nitrogen fertilizer treatments reduced protein content by 0% to 1.2%, slightly increased taste value, but significantly reduced yield. Therefore, the rational application of nitrogen fertilizer was still the best choice in agricultural production. Correlation analysis showed that under both DN and NN treatments, there was a highly significant negative correlation between seed setting rate and empty grains, with correlation coefficients of -0.98. Taste value showed a highly significant negative correlation and a highly significant positive correlation with protein and amylose, respectively.
