Fertilizer Requirement Pattern of New Maize Varieties Yundan 20
摘要
Abstract
[Objective] The aim was to explore the fertilizer requirement pattern of new maize varieties Yundan 20 and formulate high yield culture system of Yundan 20.[Method] We used the high-yielding maize varieties Yundan 20 as experiment object, designed a double factors completely randomized block test, studied the effect of different base fertilizer and different top application treatment on the agronomic traits and yield of Yundan 20.[Result] The yield of no fertilizer treatment was the lowest;the yield of the treatment with 450-600 kg/hm2 top application was higher, while, the lodging-resistance capability was weak;there was no significant difference between the treatment with 450-600 kg/hm2 top application and 300 kg/hm2 top application;the treatment with 750 kg/hm2 base fertilizer and 300 kg/hm2 top application was the most appropriate fertilizer rate, and its yield was 11 425.50 kg/hm2, furthermore, its disease resistance, lodging resistance and plant agronomic traits were better than others.[Conclusion] The suitable fertilizer rate is 750 kg/hm2 base fertilizer and 300 kg/hm2 top application.关键词
