摘要： 为了研究不同植物生长调节剂对寒地水稻产量和品质的影响，在大田条件下，以寒地水稻‘空育131’为材料，叶面喷施4种植物生长调节剂，调查叶龄及茎蘖动态变化，研究水稻抽穗后物质生产、转运和输出变化，比较农艺性状、产量构成、产量及品质变化的差异。结果表明：与CK相比，叶面喷施ND调节剂明显加速了水稻叶龄进程，增加了水稻分蘖茎数、穗长以及抽穗至乳熟阶段水稻茎鞘物质的输出率和转运率，显著提高了水稻抽穗期的光合势和净同化率，提高了水稻籽粒千粒重、穗粒数以及单株产量，进而提高了水稻产量，实现产量增幅7.04%，BaDao调节剂次之；另一方面，叶面喷施ND和BaDao提高了稻谷糙米率和精米率，以ND表现最佳。而喷施PY显著降低植株高度和节间长度，抑制了水稻株高和节间长度的正常生长，明显降低了稻米的垩白率、垩白大小和垩白度，其次是BaDao调节剂。以上试验研究表明，叶面喷施ND和BaDao调节剂，可提高寒地水稻籽粒产量，改善稻米品质。

Abstract: In order to study the effects of different plant growth regulators on the yield and quality of rice in cold area, a rice cultivar, ‘Kongyu 131’ with four treatments of spraying plant growth regulators (PGRs) was employed to study leaf and tiller dynamic changes, changes of material production, transport and the output of rice after heading, different traits, yield components, yield and quality changes of agronomy, and the effects of PGRs on rice quality in a field experiment. The results showed that, compared with CK, spraying ND regulator significantly accelerated the leaf age of rice, increased the output rate and transport of tillers, panicle length and the number of?rice?heading to milk stage of rice leaf sheath rate, significantly increased the heading stage of rice photosynthetic potential and net assimilation rate, improved the rice grain weight, grain number and yield per plant, and increased rice yield by 7.04%. Yield increases were obtained with ND, followed by BaDao. On the other hand, foliar application of ND and BaDao improved the brown rice rate and milled rice rate, and ND showed the best effect. The spraying of PY significantly reduced plant height and internode length, inhibited the normal growth of plant height and internode length, significantly reduced chalky rice, percentage of chalky size and chalkiness degree, followed by BaDao. The above experiments showed that foliar application of ND and BaDao could improve the rice grain yield in cold region and improve the quality of rice.
