微肥在玉米生产田的施用效果早有报道,但关于在种子田施用效果的报道则较少。玉米是吉林省的主要作物,每年都需要生产大量的杂交种子。种子生产既要求获得较高的产量,又要求有较高的质量。高量磷肥的施用是引起和加重玉米缺锌的重要原因。而在玉米种子生产中,施足磷酸二铵仍是提高产量的有效保证。在这种情况下,种子田中的有效锌等微量元素能否保证玉米生长发育的需要,种子田施用锌等微肥有何效果?为此,我们于1990年～1991年在校教学实验场进行了本项试验,以探讨施锌、硼对玉米种子产量和质量的影响,为提高种子生产效率提供参考依据。
The application effects of trace fertilizers in corn fields have long been reported, but there are few reports on the application effects of the fertilizers in the field. Corn is a major crop in Jilin Province and requires a large number of hybrid seeds to be produced each year. Seed production requires both higher yields and higher quality. High phosphorus fertilizer application is caused and aggravated maize zinc deficiency is an important reason. In the corn seed production, Shippu diammonium phosphate is still an effective guarantee to increase production. In this case, the effective seed zinc and other trace elements in the field can ensure the growth and development of corn needs, seedling application of zinc and other micronutrients what effect? For this reason, we in 1990 to 1991 in the school teaching experiment field This experiment was conducted to explore the effects of zinc and boron fertilizers on the yield and quality of maize seeds and provide references for improving the seed production efficiency.
