1979—1981年我们在研究"春玉米高产栽培技术及理论中,从玉米对矿质营养的吸收方面进行了测定和分析。本文就玉米亩产籽粒1,400斤情况下,对营养元素吸收的特点进行探讨,希望对玉米合理施肥和提高产量提供依据。关于玉米需肥规律的研究,前人曾有不少报道,但产量水平都不高,春玉米是600—700斤的,夏玉米是200—250斤的;近年来夏玉米有亩产800多斤进行研究的,而春夏玉米千斤以上的报道不多。
In 1979-1981, we studied and measured the absorption of mineral nutrition from maize in the study of high-yielding spring maize cultivation technology and theory.In this paper, the characteristics of nutrient absorption were investigated under the condition of 1,400 kg per mu of kernel of maize Explore and hope to provide the basis for reasonable fertilization and yield increase of corn.Research on the law of fertilizer demand of maize, there have been many reports before, but the production levels are not high, spring corn is 600-700 pounds, summer corn is 200- 250 pounds; in recent years, there are more than 800 kilos of summer maize per mu for research, but little is reported in the spring and summer of corn.
