三年来,我們在总結全国著名劳动模范馬同义同志提出的“土肥相融”培肥經驗的基础上,于1960—1961年继續在河南省长葛县坡胡人民公社孟排試驗場进行了以施用有机肥为主的培肥試驗研究,企图进一步証实和阐明“土肥相融”原理在具体农业生产上的运用及其对小麦生长发育的关系。通过田問試驗,我們着重在小麦生育的关鍵时期(返青—拔节),对根系活动、地上部生育、土壤养分动态间的相互关系和作用,进行了一系列的观察测定,現仅将所得試驗結果分别討論于后。
In the past three years, on the basis of summing up the experience of fertilizing “soil and fertilizer” advanced by comrade Ma of the famous national model worker, we continued to carry out the test at Meng Pai of Pengpo People’s Commune, Changge County, Henan Province in 1960-1961 In this paper, we try to further confirm and elucidate the application of the principle of “soil and fertilizer blending” in the concrete agricultural production and its relationship with the growth and development of wheat. Through the field experiments, we focused on a key period of wheat (green-jointing), conducted a series of observations on the interactions and effects of root activity, aboveground fertility and soil nutrient dynamics. The test results are discussed later.
