我所从1978年开始,对主伐前马尾松进行硫酸黑膏采脂试验,增产效果显著;1979年在深入探索高效配方和制法的同时,着重探讨硫酸黑膏采脂的工艺条件,现报告如次。(一)试验目的和要求目前,国内外对硫酸黑膏的配制尚未定型生产,国内沿用的酸膏浓度(50%),也是借鉴国外的资料。如何根据我省的实际情况,寻找高效、价廉、易得的配制原料,值得探讨。为此,我所于1978年进行了十多种原料配方筛选试制,结果认为用硫酸、油菜饼粉、重松节
Since 1978, we have carried out sulfated black sesame oil-picking test on pre-main-cut masson pine, which has shown a remarkable yield increase effect. In 1979, while thoroughly exploring efficient formulating and manufacturing processes, we focused on the technological conditions for the production of sulfuric acid-black paste. If the times. (A) the purpose and requirements of the test At present, the preparation of sulfuric acid black ointment at home and abroad have not yet been stereotyped production, the domestic use of acid cream concentration (50%), but also learn from foreign information. How to find the efficient, cheap and easy-to-prepare raw materials according to the actual situation in our province is worth discussing. To this end, I conducted in 1978, more than 10 kinds of raw material screening screening trial, the results that the use of sulfuric acid, rape cake powder, heavy pine
