研究高粱吸肥特性,是从施肥上提出增产技术措施和改进施肥方法的基础。关于这方面的研究,国内过去报道不多,杂交高粱的资料更为少见。为此,我们于1978和1979年进行了高粱吸肥特性的试验。 试验分筒栽和盆栽两组。筒栽利用50×65厘米陶瓷筒进行,筒内面积为0.2平方米。筒埋在地下,上沿露出地表15厘米。筒内35厘米深以下装河砂,上面装砂质草甸
Studying the characteristics of sorghum absorption of fertilizer is to put forward the technical measures of increasing yield and the basis of improving the fertilization method. On this aspect of the study, there were not many reports in the past and the data of hybrid sorghum were even more rare. For this reason, we carried out experiments on sorghum absorption characteristics in 1978 and 1979. Test tube and potted plants in two groups. Tube planting using 50 × 65 cm ceramic tube, barrel area of 0.2 square meters. Buried in the ground tube, exposed along the surface of 15 cm. Drum below 35 cm deep mounted sand, mounted above the sandy meadow
