Embodiment 1

[0041] Embodiment 1 The preparation of product 1 of the present invention

[0042] Take 1200kg of alcohol waste liquid from the sugar cane sugar factory, let it stand for clarification, and obtain the supernatant, then heat the supernatant to 75°C for evaporation and concentration to obtain 200kg of the concentrate, add nitric acid to the concentrate until the pH of the concentrate is 3. Stand at room temperature and activate for 18 hours, then add ammonia water to adjust the pH to 7 to obtain active humic acid liquid, dry the active humic acid liquid, pulverize, and sieve to obtain active humic acid, about 120kg for later use.

[0043] 30kg of polyacrylamide (purchased from Renqiu Zhenghao Chemical Products Co., Ltd.) and 300kg of rapeseed cake were weighed, crushed, sieved, and set aside.

[0044] Weigh 250g 20% ​​of the wettable powder of erythoxystrobin for subsequent use (self-made) (equivalent to 50g of the active ingredient);

[0045] Mix the above-obtained active humi...

Embodiment 2

[0047]Example 2 Preparation of product 2 of the present invention

[0048] Get 1600kg of beet sugar factory alcohol waste liquid, leave standstill to clarify, obtain supernatant liquid, then described supernatant liquid is heated to 85 ℃ and carry out evaporative concentration, obtain concentrated liquid 350kg, in concentrated liquid, add nitric acid until the pH of concentrated liquid is 2, stand for activation at room temperature for 24 hours, then add ammonia water to adjust pH to 6.5 to obtain active humic acid solution, dry, pulverize and sieve the active humic acid solution to obtain active humic acid, about 150kg is for standby use.

[0049] Weigh 50kg of polyacrylamide (purchased from Renqiu Zhenghao Chemical Products Co., Ltd.) and 400kg of peat moss, respectively, and pulverize, sieve, and reserve.

[0050] Take by weighing 334g30% of the 30% fenoxystrobin WP for subsequent use (self-made) (the active ingredient is 100g);

[0051] The above-obtained active humic aci...

Abstract

The invention relates to a humic acid type water-retaining slow-release controlled-release organic fertilizer prepared from wastes of sugar mills and alcohol plants. The fertilizer contains active humic acid, a water-retaining agent, an organic fertilizer and a bactericide. The water-retaining slow-release controlled-release organic fertilizer can effectively promote crops to take root and increase production.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a humic acid-type water-retaining slow-release and controlled-release organic fertilizer utilizing waste from sugar factories and alcohol factories. Background technique [0002] Sugar factory alcohol waste liquid is a kind of acidic waste liquid left after alcohol is prepared with residual molasses from sugar cane sugar factories, beet sugar factories and other sugar factories. This type of waste liquid contains a large amount of organic matter and beneficial elements. my country currently discharges millions of tons of this waste liquid every year, which has caused serious environmental pollution problems. At present, the main utilization method of this waste liquid is still direct irrigation. On the one hand, this extensive application method is not conducive to the effective utilization of nutrients; on the other hand, due to transportation and other restrictions, this application ...
