近年来,各地农村纷纷兴办大米加工厂,因条件有限,对加工后产生的水稻谷壳等副产品无法处理,通常弃之路旁用火烧。利用水稻壳制造堆肥养鱼,开辟了有机肥养鱼新肥源。 1.高温谷壳堆肥法 选择地势平坦、鱼塘附近为堆肥场所。按谷壳500公斤、猪牛粪300公斤、人粪尿100公斤和水750—1000公斤比例混和,边拌边堆,拌一批、堆一批,直至堆成高2米、宽5至6米长方形大堆。浇透水后,在堆的表面覆盖5至6厘米厚的细土或用污泥封好,堆后5—10天后即可施入鱼塘培肥水质,增殖饵料。 2.低温谷壳堆肥法 冬季鱼塘干塘清整时,在鱼塘一角,开挖一直径2—3米,深0.5米的堆肥坑,将谷壳在坑内
In recent years, rice processing factories have been set up in rural areas all over the country. Due to limited conditions, by-products such as rice chaff generated after processing can not be handled. The use of rice hulls to create composting fish, opened up a new source of organic fertilizer fish. 1. High-temperature chaff compost selection flat topography, pond near the compost place. 500 kilograms of chaff, 300 kilograms of pig manure, 100 kilograms of human excrement and 750-1,000 kilograms of water are mixed. While mixing and batching, a batch of heaps are stacked until the heaps reach a height of 2 meters and a width of 5 to 6 Large rectangular pile of rice. After pouring water, the surface of the pile covered with fine soil 5 to 6 cm thick or sealed with sludge, 5-10 days after the heap can be applied to fertilize the water quality of fish ponds, proliferation of feed. 2. Low-temperature chaff compost Winter ponds dry ponds clean up in the corner of the pond, excavation of a diameter of 2-3 meters, 0.5 meters deep composting pit, chaff in the pit
