Embodiment 1

[0024] Implementation location: BLD palm plantation in Bintulu, Sarawak, Malaysia

[0025] Implementation material: oil palm fruit shreds (grain size 1-6cm)

[0026] The fermentation method that the present invention utilizes oil palm stalk to produce organic fertilizer specifically comprises the following steps:

[0027] Crush 800 kg of oil palm fruit stalks to a particle size of 1 to 6 cm, soak them in 5 times the weight of sewage for 5 days, and control the water content of the stalks at 70% after drainage. Before composting, VT bacteria agent was added at a weight ratio of 0.3% relative to the oil palm fruit stalk, and the C / P ratio was adjusted to 100:1 at one time. According to the nature of raw materials, according to the amount of pure nitrogen to be converted into urea by adjusting the C / N ratio to 30, the C / N ratio of the material is adjusted with urea. After composting starts, urea is divided into 6 times and added in equal amounts. Added every 1d interval.

[0035] The fermentation method that the present invention utilizes oil palm stalk to produce organic fertilizer specifically comprises the following steps:

[0036] Crush 800 kg of oil palm fruit stalks to a particle size of 1 to 6 cm, soak them in 3 times the weight of sewage for 1 day, and control the water content of the stalks at 70% after drainage. Before the start of composting, VT inoculum was added at a weight ratio of 0.1%, and the C / P ratio was adjusted to 150:1 at one time. According to the nature of raw materials, according to the amount of pure nitrogen to be converted into urea by adjusting the C / N ratio to 20, the C / N ratio of the material is adjusted with urea. After the composting starts, the urea is added in 6 equal amounts. Added every 1d interval.

Abstract

The invention provides a fermentation method for producing organic fertilizer by oil palm pedicel, which comprises the steps of crushing the oil palm pedicel and soaking in sewage; inoculating microbial agent VT accounting for 0.1-0.5 percent of the fresh weight of the pedicel; and fermenting after even mixing. Before composting, C / P ratio is adjusted to be 75-150:1; and after composting, the C / Nratio of the materials is adjusted to be 20-35:1. The composting fermentation process can be controlled within 25d, the content of organic matter can be as high as 50 percent, 15-20 percent of area ofthe fermentation field can be saved, and the quality of the compost product is effectively improved.

Description

technical field [0001] The invention relates to a fermentation method, in particular to a fermentation method for producing organic fertilizer by using oil palm stalks. Background technique [0002] Oil palm is a large-scale oil crop planted in tropical and subtropical regions, and is widely planted in Southeast Asia. For example, Malaysia has more than 4 million hectares of planting area and more than 400 oil mills. The oil mills will leave a lot of oil palm fruit stalks and sewage every year (the weight ratio of fruit stalks and sewage is about 3 to 4:1). On the one hand, these wastes left by oil palm fruit oil extraction have brought pressure on the local environment, and on the other hand, it has also brought the possibility of centralized treatment and recycling of oil palm fruit stalks. As an effective way to reduce, harmless and recycle organic solid waste, composting technology has always attracted people's attention. However, the oil palm stalk has the characteris...
