青贮玉米种植密度较大,故在青贮玉米生长过程中群体与个体发育、前期生长与后期生长矛盾比较突出。尤其近几年来,采用从广西引进的玉米品种,植株生长3m以上,使矛盾更加突出。 合理的种植方式,是解决青贮玉米群体发育与个体发育、前期生长与后期生长矛盾的有效途径之一。1996年,我们对青贮玉米不同种植方式进行了比较试验。结果表明:产量为一穴两株栽培>宽窄行栽培>常规单株栽培。现将本试验总结如下。1 材料和方法
Silage corn planting density is larger, so in the process of silage corn population and individual development, early growth and later growth of contradictions more prominent. Especially in recent years, the introduction of maize varieties from Guangxi, plant growth of 3m or more, so that the conflict is even more prominent. Reasonable planting method is one of the effective ways to solve the contradiction between silage corn population development and individual development, early growth and later growth. In 1996, we compared the different planting methods of silage corn. The results showed that the yield was one hole two cultivated> wide and narrow row cultivation> conventional monoculture. The test is summarized as follows. 1 Materials and methods
