黑龙江省九三垦区位于我国黑土带,地处东经24°57′～126°12′,北纬48°～50°。据黑龙江省“八一”农垦大学1989年对垦区土壤分析,80～90％黑土耕地铜素有效量处于缺和10～20％耕地处于较缺水平;土壤含铜量(有效量)在0.75～1.10ppm之间。为此,我所自1989～1990年开展了铜肥施用效果的研究,结果表明,施铜对春小麦有一定的抗倒、防病、增产效果。一、试验材料与方法 1.小区试验在本所试验地。其基础肥力
The ninety-three reclamation area in Heilongjiang Province is located in the black soil zone of China. It is located between 24 ° 57 ’~ 126 ° 12’ east longitude and 48 ° ~50 ° north latitude. According to the soil analysis of reclamation area in Heilongjiang August 1 Land Reclamation University in 1989, the effective amount of copper in 80 ~ 90% of arable land in black soil is in the deficient level and the deficient area of 10 ~ 20% of the arable land. The copper content in soil is between 0.75 ~ 1.10ppm between. To this end, I conducted from 1989 to 1990, the study of the effect of copper fertilizer application, the results show that copper on spring wheat have some anti-down, disease prevention, increase production. First, the test materials and methods 1. Community test in our test. Its basic fertility
