衡南稻田肥料,以氹肥(氹音‘妥当’的当,即坑之意)为主,估计约占水稻肥料施用量90％以上,占施用面积80％以上。其积制方法好坏,直接影响水稻产量颇大,所以总结群众氹肥积制方法与经验,予以提高,实属必要。 一、一般积制方法 (一)材料:积制氹肥所用材料,极不一致,主要的有下列几种: 1.草皮:其来源是在秋收後,冬季或早春铲刮田埂、路边、山坡上的草皮,其质量出入颇大,有的草多土少,有的草少土多。 2.家淤:包括垃圾、稿稭、废物、脏水等(也有加入草皮廐肥一同沤製的)。随时在房屋附近小坑中沤製。在挑出时有的已腐烂,有的仍现原样,质量也极不一致,但农民认为是良好的拌淤。他们说:‘无家淤,氹不易作肥’(腐烂)。 Hengnan paddy fertilizer, to Taipa (Taipin ’proper’ when, that pit meaning), estimated to account for about 90% of the amount of rice manure, accounting for more than 80% of the area. The method of product plotting is good or bad, which has a direct impact on the yield of rice. Therefore, it is necessary to sum up the methods and experience of mass production in Taipa. First, the general method of product accumulation (a) material: accumulated materials used in Taipa, very inconsistent, there are the following main: 1. Turf: The source is in the autumn harvest, winter or early spring scraping fields, roadside, hillside On the turf, the quality of a considerable discrepancy, and some more grass and less soil, some grass less earth. 2. Home silt: Including rubbish, draft straw, waste, dirty water, etc. (also joined the turf and fat system). Anytime in the pit near the house system. Some of them were decayed when they were picked out, while others were still as they were and their quality was extremely inconsistent. However, peasants considered it as a good solution to mixing silt. They said: ’Homeless siltation, Taipa not easy to make fertilizer’ (decay).
