本文拟在各种栽培条件下,探讨田间甘薯的干物质生产,分析其干物质生产构成,试图找出增加干物质产量的合理方法。为了获得各种生育类型,在肥沃度不同的田间,以不同栽植密度和栽植时期进行试验。不过,试验的目的并非探讨各种处理的影响,而是通过处理,使生育型发生差异,增加各种性状的变异幅度,希望把性状相互间的关系集中于干物质的生产方面加以探讨。试验材料及方法为了获得各种生育类型,以甘薯农林1号品种在肥沃及瘠薄二类旱地上进行试验,二类旱地上均设早插区和晚插区,而且还分别设置密植区和稀植区。重复—次,共计8区,试验面积为15公亩。肥沃地指客入大量河流砂质冲积土、种植大麦等产量极高的旱
This paper intends to explore the dry matter production of sweet potatoes under various cultivation conditions and analyze their dry matter production composition in an attempt to find a reasonable way to increase dry matter production. In order to obtain a variety of fertility types, fertile fields in different fields at different planting densities and planting period for testing. However, the purpose of the experiment is not to explore the effects of various treatments. Rather, the purpose of the experiment is to deal with differences in the reproductive types and to increase the variability of the traits. It is hoped that the relationship between traits will be discussed in terms of the production of dry matter. Test materials and methods In order to obtain a variety of types of fertility, with sweet potato farming and forestry 1 variety in fertile and barren type two dry land experiments, two types of dry land are set up early plug region and late plug region, but also were set densely populated and thin Planting area. Repeat - times, a total of 8 areas, the test area of 15 acres. Fertile land refers to the large volume of sandy alluvial soil that has been introduced into the river and the high yield of barley
