摘要:
为探究种植方式及栽培密度对玉米产量的影响，以黑龙江省第一积温带下限主栽品种兴垦3号（半紧凑型）和江单1号（紧凑型）为试验材料，设置5个栽培密度，采用裂区设计，对黑龙江省常用的5种栽培方式的产量进行比较研究。结果表明：5种栽培方式间的产量达到极显著水平，产量顺序由大到小依次为50 cm小垄栽培方式、1465栽培方式、130 cm大垄双行、65 cm正常垄栽培方式、65 cm偏垄栽培方式；江单1号5种密度的产量顺序由大到小依次为7.875万、6.750万、5.625万、9.000万和4.500万株·hm-2;兴垦3号5种密度的产量顺序由大到小依次为6.750万，5.625万、4.500万、7.875万、9.000万株·hm-2。江单1号最适宜密度是7.875万株·hm-2，兴垦3号最适宜密度是6.750万株·hm-2。
Abstract:
In order to discuss the effects of plant method and density on yield of maize,adopting the split plot design,the main varieties planting in Heilongjiang province first accumulated temperature area limit-Jiangdan No.1(compact)and Xingken No.3(Semi-compact)were used as test materials to conduct the experiment with 5 frequently-used cultivation methods and 5 cultivation densities,and using.The results showed that there was very significant difference in the yield of 5 cultivation methods.The order of yield was 50 cm micro-ridge cultivation method＞1465 cultivation method＞130 cm macro-ridge cultivation method of double lines＞65 cm normal-ridge cultivation＞65 cm partial-ridge cultivation method.The yield order of 5 densities was 78.75 thousand plants per hm2＞ 67.50 thousand plants per hm2＞56.25 thousand plants per hm2＞90.00 thousand plants per hm2＞45.00 thousand plants per hm2.67.5 thousant plants per hm2＞56.25 thousand plants per hm2＞45.00 thousand plants per hm2＞78.75 thousand plants per hm2＞90.00 thausand plants per hm2.The density of 78.75 thousand plants per hm2 was the most suitable for Jiangdan No.1 and 56.25 thousand plants per hm2 was for Xingken No.3.
