摘要:

【目的】研究新疆高温环境下喷施锌、硼、钙叶面肥对玉米主要农艺性状与制种产量的影响,为新疆玉米高效、优质和高产制种生产提供参考。【方法】以玉米自交系CXJ75(母本)和CXJ380(父本)为材料,采用硫酸锌、硼酸钠、葡萄糖酸钙作为叶肥,设置12个不同的叶肥配比处理和1个CK处理,采用随机区组设计。测量与分析不同叶肥配比处理下玉米的农艺性状和制种产量。【结果】(1) 不同配比的叶肥均可一定程度延缓开花期,缩短开花吐丝间隔期。(2) 1%浓度的硫酸锌、硼酸钠与葡萄糖酸钙叶肥混合喷施效果最佳。(3) 玉米产量与多项农艺性状均呈线性关系,并与穗行数、穗粗、百粒重、结实率、单穗粒重和单穗籽粒数的相关性较高。【结论】新疆玉米杂交制种遭受花期高温胁迫时,喷施1%浓度的硫酸锌、硼酸钠与葡萄糖酸钙混合叶肥(5 000 L/hm2),可以有效的提高制种产量。

Abstract:

【Objective】 To investigate the effects of foliar application of zinc, boron, and calcium fertilizers on the main agronomic traits and seed production yield of maize under high-temperature conditions in Xinjiang. 【Methods】 Maize inbred lines CXJ75 (female parent) and CXJ380 (male parent) were used as experimental materials, zinc sulfate, sodium borate, and calcium gluconate were applied as foliar fertilizers. Twelve different foliar fertilizer ratio treatments and one control (CK) treatment were established, arranged in a randomized block design. The agronomic traits and seed production yield of maize under different foliar fertilizer treatments were measured and analyzed. 【Results】(1)Different ratios of foliar fertilizers could delay the flowering period to some extent and shorten the interval between anthesis and silking. (2) The mixed application of 1% zinc sulfate, sodium borate, and calcium gluconate foliar fertilizers yielded the best results.(3)Maize yield showed a linear relationship with multiple agronomic traits, with high correlations observed with the number of kernel rows per ear, ear diameter, 100-kernel weight, seed setting rate, grain weight per ear, and the number of kernels per ear. 【Conclusion】 Under high-temperature stress during the flowering period in Xinjiang, the foliar application of a mixed fertilizer containing 1% zinc sulfate, sodium borate, and calcium gluconate (5,000 L/hm2) can effectively improve seed production yield. This findings have provided a reference for efficient, high-quality, and high-yield maize seed production in Xinjiang.
