[0013] A kind of preparation method applicable to the organic fertilizer of sandy soil, comprises steps:
[0014] 1. Raw materials
[0015] In parts by mass, 40-50 parts of lignified organic matter, 20-30 parts of fibrous organic matter, 10-20 parts of industrial waste residue of organic matter, 5-15 parts of poultry and livestock manure, 3-8 parts of oil industry waste, mix evenly, Obtain organic mixture;
[0016] 2. Aerobic fermentation
[0017] Take the organic mixture prepared in step (1), adjust the moisture content to 55-63%wt., cover it with plastic film and stack it for fermentation, wait for the temperature to rise to 50°C-60°C, keep it for 6-10 days; turn the pile, wait for the temperature Rise to 50°C to 60°C and keep for another 6 to 10 days. During this period, uncover the film to ventilate once a day, each time ventilating for 8 to 15 minutes; after the fermentation is completed, one fermentation material A is obtained;
[0018] 3. Semi-aerobic fermentation. ...
Embodiment 1
[0052] Embodiment 1: a kind of preparation method that is applicable to the organic fertilizer of sandy soil, the steps are as follows:
[0053] 1. Selection of raw materials
[0054]45 parts of sawdust, 25 parts of rice husk, 15 parts of a 1:1 composition of furfural residue and xylitol residue, 10 parts of cow dung, 5 parts of a 1:1 composition of soybean oil residue and rapeseed oil residue, and mix all the ingredients evenly , to get the organic mixture;
[0055] 2. Aerobic fermentation
[0056] Take the above-mentioned organic mixture, adjust the moisture content to 60%wt., cover it with a plastic film and stack it for fermentation. When the temperature rises to 55°C, keep it for 8 days; turn it over, wait for the temperature to rise to 55°C, and keep it for another 8 days. During this period, the film was uncovered to ventilate once a day, and ventilated for 10 minutes each time. After the fermentation is over, the primary fermentation material A is obtained;

Embodiment 2
[0060] Embodiment 2: a kind of preparation method that is applicable to the organic fertilizer of sandy soil, the steps are as follows:
[0061] 1. Selection of raw materials
[0062] 50 parts of pulverized cotton stalks, 20 parts of corn cobs, 10 parts of bagasse and xylitol residue 2:1 composition, 13 parts of chicken manure, 7 parts of corn oil residue and soybean oil residue 1:2 composition, all The raw materials are mixed evenly to obtain the organic mixture;
[0063] 2. Aerobic fermentation
[0064] Take the above organic mixture, adjust the moisture content to 58%wt., cover it with plastic film and stack it for fermentation. When the temperature rises to 58°C, keep it for 7 days; turn it over, wait for the temperature to rise to 50°C, and keep it for another 10 days. During this period, the film was uncovered to ventilate once a day, and each time was ventilated for 8 minutes. After the fermentation is over, the primary fermentation material A is obtained;
