超级稻专用肥对不同种植方式的适应性研究

Adaptability of super rice specialized fertilizer on different cultivation patterns of rice

为了探明超级稻专用肥对不同种植方式的适应性,以常规超级稻合美占为材料,通过大田试验,研究了施用超级稻专用肥(SSF)对人工插秧、机插秧、撒直播、免耕撒直播、机穴直播、抛秧、免耕抛秧7种种植方式下水稻产量和品质的影响。结果表明:与施用常规化肥(CK)相比较,SSF显著提高人工插秧、机插秧、撒直播、免耕撒直播、机穴直播、抛秧、免耕抛秧7种种植方式的产量,分别提高20.03%、12.36%、22.26%、9.2%、22%、21.93%和17.56%;SSF亦能显著提高人工插秧和机插秧稻米的胶稠度,以及撒直播稻米的蛋白质含量,而显著降低了抛秧稻米的垩白粒率和垩白度。超级稻专用肥对上述7种种植方式均具有良好的适应性。

In order to explore the adaptability of super rice specialized fertilizer on different cultivation patterns of rice,the field experiments were carried out to study effects of super-rice specialized fertilizer on rice yield and quality of manual transplanting,mechanized transplanting,manual broadcasting,no-tillage manual broadcasting,precision hill-drop drilling,manual seedling broadcasting and no-tillage manual seedling broadcasting by using a super inbred rice cultivar,Hemeizhan.Results showed that compared with CK,application of super rice specialized fertilizer increased significantly yield of manual transplanting,mechanized transplanting,manual broadcasting,no-tillage manual broadcasting,precision hill-drop drilling,manual seedling broadcasting and no-tillage manual seedling broadcasting,by 20.03%,12.36%,22.26%,9.2%,22%,21.93% and 17.56%,respectively,and improved significantly gel consistency of manual transplanting and mechanized transplanting,protein content of manual broadcasting,and reduced significantly chalky grain rate and chalkiness of manual seedling broadcasting,therefore,super-rice specialized fertilizer can adapt to 7 different cultivation patterns above.
