蚕粪是优质的完全肥料,含主要营养元素约为N3—4％,P_2O_5—2.5％,K_2O1.5—2.0％外,还含有叶绿素和吲哚乙酸(IAA),尿酸(Uric acid)的衍生物。最近发现尚含有一种新的梢物激素——正三十烷醇(T.RIA)等。都对植物有极性传导的生长刺激素的效应。 我省1973—1974年在大面积水稻生产上施用蚕粪液获得普遍增产,增产幅度为5—25％左右。本试验以应用蚕粪提取液对花生进行浸种及根外喷施处理,作多因子,多水平的正交试验研究。以探索蚕粪提取液喷施春花生的最适时期和浓度的增产效果。并初步探讨大田农作物在正交试验上的应用方法。
Silkworm excrement is a high quality and complete fertilizer with the main nutrients of about N3-4%, P_2O_5-2.5% and K_2O1.5-2.0%. It also contains derivatives of chlorophyll, indoleacetic acid (IAA) and uric acid Things. Recently found still contains a new shoot hormone - n-triacontanol (T.RIA) and so on. Both have the effect of plants having polar conduction of growth-stimulating hormone. Our province from 1973 to 1974 in a large area of rice production application of silkworm manure to achieve a general increase in yield, increase rate of about 5-25%. In this study, the application of silkworm excrement extract soaking peanut and root spray treatment, for multi-factor, multi-level orthogonal experiment. In order to explore the optimum time and concentration of silkworm excrement sprayed peanut stimulation effect. The preliminary research on the application of field crops in orthogonal experiment.
