Embodiment 1

[0020] Embodiment 1: A kind of preparation method of grape straw organic fertilizer

[0021] A method for preparing grape straw organic fertilizer, comprising the following processing steps.

[0022] (1) Straw crushing

[0023] Collect grape stalks, crush the stalks (hammer mill) into 8mm uniform particles, and set aside.

[0024] (2) Steam explosion

[0025] Soak the pulverized grape straw particles at a temperature of 25° C. for 16 hours with sufficient agricultural water, and set aside.

[0026] The soaked straw particles were taken out, placed in the steam explosion equipment, and the steam explosion treatment was carried out with the parameters of water-material ratio 1:6, pressure maintenance time 8min, and steam pressure 1.7MPa.

[0027] (3) High temperature fermentation

[0028] Cool the steam-exploded straw to 75° C., then fully mix 22 parts by weight of the straw, 77 parts by weight of pig manure, and 0.3 part by weight of the fermentation agent.

Embodiment 2

[0042] Embodiment 2: A kind of preparation method of grape straw organic fertilizer

[0043] A preparation method of grape straw organic fertilizer, comprising the following steps:

[0044] Step 1: crushing the grape straw to obtain grape straw particles with a particle size of 5-10mm, and set aside;

[0045] Step 2: Soak the grape straw particles in water for 24 hours at a temperature of 5° C.; then perform steam explosion treatment on the soaked grape straw particles;

[0046]Step 3: Carry out high-temperature fermentation: cool the grape straw granules after steam explosion to 70° C., then mix 20 parts by weight of grape straw granules, 75 parts by weight of pig manure and 0.1 part by weight of fermentation bacteria to obtain a mixture; The mixture is placed in separate piles, with an average weight of 2.0 tons per pile, and the slope of the pile is 40°; during the fermentation process, the temperature of the material at a depth of 25 cm in the fermentation pile is measure...

Abstract

A preparation method of a grape straw organic fertilizer comprises the following treatment steps: (1) straw crushing; (2) steam explosion; (3) high-temperature fermentation; (4) medium-temperature fermentation; (5) normal-temperature fermentation; and (6) drying and crushing. The prepared grape straw organic fertilizer can increase soil organic matters, improve soil nutrients and pH, realize rapidsoil improvement and fertilization, and promote crop growth.

Description

technical field [0001] The invention relates to a method for preparing grape straw organic fertilizer, which belongs to the technical field of farmyard manure production. Background technique [0002] In the process of fermenting and producing commercial organic fertilizer with pig manure as raw material, it is necessary to add and mix a certain proportion of sawdust to improve the efficiency of aerobic fermentation. In recent years, commercial wood chips have been widely used in the production of pellet fuel, and the price has risen sharply. The average price of commercial sawdust in Zhejiang has risen to 350 yuan / ton, and even rose to 500 yuan / ton in some areas in northern Zhejiang, which directly led to an increase in the cost of organic fertilizer production. The grape planting area in Zhejiang Province is 32,500 hectares, with an annual output of 100,000 tons of grape straw. Yongkang took the lead in creating a "stalk-for-fertilizer" collection, storage and transporta...
