Embodiment 1

[0028] A method for promoting the decomposition of Zizania stalks, comprising the following steps: crushing 50 kg of Zizania stalks to 1-3 cm, spreading 12.5 kg of crushed Zizania stalks evenly on the ground, evenly spreading 2.5 kg of dried chicken manure, and then evenly spreading 0.5kg of urea is 25 to adjust the C / N ratio, evenly spray 300g of fermented liquid with a watering can, and then the remaining 37.5kg of crushed Zizania stalks are superimposed into four layers according to the above operations, and the moisture content is adjusted to 65% by watering, and then Cover tightly with plastic cloth, turn over when the compost center reaches 60°C, and perform anaerobic fermentation for 45 days to obtain decomposition products.

Embodiment 2

[0030] A method for promoting the decomposition of Zizania stalks, comprising the following steps: crushing 50 kg of Zizania stalks to 1-3 cm, spreading 12.5 kg of crushed Zizania stalks evenly on the ground, evenly spreading 2.5 kg of dry cow dung, and then evenly spreading 0.4kg of urea is 25 to adjust the C / N ratio, evenly spray 300g of fermented liquid with a watering can, and then the remaining 37.5kg of crushed Zizania stalks are superimposed into four layers according to the above operations, and the moisture content is adjusted to 65% by watering, and then Cover tightly with plastic cloth, turn over when the compost center reaches 60°C, and perform anaerobic fermentation for 45 days to obtain decomposition products.

Embodiment 4

[0032] A method for promoting the decomposition of Zizania stalks, comprising the following steps: crushing 50 kg of Zizania stalks to 1-3 cm, spreading 12.5 kg of crushed Zizania stalks evenly on the ground, evenly spreading 2.5 kg of dry sheep dung, and then evenly spreading 0.4kg of urea is 25 to adjust the C / N ratio, evenly spray 300g of fermented liquid with a watering can, and then the remaining 37.5kg of crushed Zizania stalks are superimposed into four layers according to the above operations, and the moisture content is adjusted to 65% by watering, and then Cover tightly with plastic cloth, turn over when the compost center reaches 60°C, and perform anaerobic fermentation for 45 days to obtain decomposition products.

Abstract

The invention discloses a method for promoting zizania aquatica straw decomposition. The method comprises the following steps: selecting a composting place; preparing a fermentation liquor, wherein brown sugar is dissolved in water at the temperature of 80-100 DEG C, the ratio of the brown sugar to the water is 1: (7-9), an obtained mixture is cooled to 30-40 DEG C, then an EM microbial agent is added, sealed fermentation is conducted for 7-12 days, and the fermentation liquor is obtained; preparing an organic fertilizer, wherein zizania latifolia straws are crushed and then are divided into aplurality of parts, mixing each part of the crushed zizania latifolia straws with livestock and poultry manure and the fermentation liquor respectively to obtain mixed products, the carbon-nitrogen ratio of the mixed products is adjusted to be (20-30): 1 with urea, the plurality of the mixed prdoucts are mixed, the water content is adjusted to be 60-70%, long strips are obtained through stacking,and are tightly coverd with plastic cloth, when the composting center reaches 60 DEG C overturning is carried out, and anaerobic fermentation is carried out for 40-55 days to obtain a decomposition product. The method has the advantages of being high in decomposition speed, high in decomposition degree, convenient to operate and easy to master by farmers.

Description

technical field [0001] The invention relates to the technical field of high-efficiency resource utilization of crop straws, in particular to a method for promoting the decomposition of wild rice stems. Background technique [0002] Zizania, scientific name wild gourd, is a perennial shallow-water grass. The economic value of wild gourd is large, and its stalk base and tender stems are thick and tender after being parasitized by fungi. It is a delicious vegetable, rich in nutrients, containing sugar, organic nitrogen, water, fat, protein, fiber, ash and amino acids. [0003] Due to the great economic benefits of Zizania, farmers in Anhui, Zhejiang and other places planted it on a large scale. According to research, the biomass of leaves and sheaths of Zizania zizania accounts for 50-70% of the total mass of Zizania zizania plants. Each mu of Zizania field can produce about 5000kg of fresh Zizania stalks, which is 2-4 times the mu straw production of rice, wheat and other cr...
