我省山区有极其丰富的树叶嫩草,它們都是很好的肥料。但因其体积較大,离山較远的地方就很难取用。因此,如何設法就地加工,缩小体积,提高单位重量內肥料成分含量,以便于运輸,使这些山肥在农业生产上发揮更大的作用,是值得研究的。为此,特于1960年9月中旬,在杭市留下附近山上,采集了泡桐、胡枝子、盐肤木、櫟类、黄檀等树叶,以之試制餅肥,已成功地制成了餅肥10种。利用树叶或杂草制造餅肥的工序是:采集原料→堆积发酵→搗碎→压制成餅。在制造过程中应注意以下事項: 1.山上的树叶虽均可用以制造餅肥,但以闊叶树种、叶片带毛不带腊质的为好,因其肥分高,易发酵。
Mountains in our province have extremely rich young leaves, they are good fertilizer. But because of its larger, far away from the mountain is difficult to access. Therefore, it is worth studying how to find ways to localize, reduce the volume and increase the content of fertilizer components per unit weight so as to facilitate the transportation and make these mountain and fertilizer play a greater role in agricultural production. To this end, especially in mid-September 1960, left in the vicinity of the Hanging Hill in Hangzhou, collecting Paulownia, Lespedeza, Rhus such as wood, oak, sandalwood and other leaves, with the pilot cake, has successfully made a cake 10 species. The use of leaves or weeds to make cake fertilizer process is: collecting raw materials → → fermentation pile → crushed into a cake. In the manufacturing process should pay attention to the following matters: 1. Although the hills of the leaves can be used to make cake fertilizer, but the broad-leaved species, leaves with hair wax without wax as well, because of its high fertilizer, easy to ferment.
