不同种植方式与密度对玉米产量的影响

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50cm小垄栽培方式、1465栽培方式、130...

Effect of Different Cultivation Methods and Density on Yield of Maize

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 method1465 cultivation method130 cm macro-ridge cultivation method of double lines65 cm normal-ridge cultivation65 cm partial-ridge cultivation method.The yield order of 5 densities was 78.75 thousand plants per hm2 67.50 thousand plants per hm256.25 thousand plants per hm290.00 thousand plants per hm245.00 thousand plants per hm2.67.5 thousant plants per hm256.25 thousand plants per hm245.00 thousand plants per hm278.75 thousand plants per hm290.00 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.
