Embodiment 1

[0035] The method for producing long-acting soil conditioner with potassium feldspar and organic waste, the technological process of the present embodiment is as attached figure 1 shown. Potassium feldspar, limestone, gypsum, magnesium sulfate, and sodium sulfate are mixed in parts by weight of 10:5:1:1:1, and the mixture is crushed to 50-100 mm by jaw crusher or other methods. Add a certain amount of coal or other fuels to the crushed mixture in the rotary kiln for roasting, the roasting temperature is controlled at 1000°C, and the roasting time is 10 minutes. After the roasting is finished, the ingredients are cooled to form a sand-like substance, and then pulverized by a wind-swept mill to form a powder with an average particle size of 0.5-1.5 mm. Add poultry and livestock excrement of equal quality to the powder, mix and carry out anaerobic fermentation for 10 days, and then add aerobic bacteria to carry out fermentation for 10 days. The fermented mixture is dried and de...

Embodiment 2

[0037] The method for producing long-acting soil conditioner with potassium feldspar and organic waste, the technological process of the present embodiment is as attached figure 1 shown. Potassium feldspar, limestone, gypsum, magnesium sulfate and sodium sulfate are mixed in parts by weight of 10:6:1:1:1, and the mixture is crushed to 50-100mm. Put the crushed mixture into a rotary kiln for roasting, the roasting temperature is controlled at 1000°C, and the roasting time is 20 minutes. After the roasting is finished, the ingredients are cooled to form a sand-like substance, and then pulverized into a powder with an average particle size of 0.5-1.5mm. Add poultry and livestock excrement of equal quality to the powder, mix and carry out anaerobic fermentation for 10 days, and then add aerobic bacteria to carry out fermentation for 10 days. The fermented mixture is dried and dehydrated by using the tail gas produced by rotary kiln roasting, and the product long-acting soil cond...

Embodiment 3

[0039] The method for producing long-acting soil conditioner with potassium feldspar and organic waste, the technological process of the present embodiment is as attached figure 1 shown. Potassium feldspar, limestone, gypsum, magnesium sulfate and sodium sulfate are mixed in parts by weight of 10:10:1:1:1, and the mixture is crushed to 50-100mm. The crushed mixture is put into a rotary kiln for roasting, the roasting temperature is controlled at 1000° C., and the roasting time is 30 minutes. After the roasting is finished, the ingredients are cooled to form a sand-like substance, and then pulverized into a powder with an average particle size of 0.5-1.5 mm. Add poultry and livestock excrement to the powder in a ratio of 9:1, and then carry out anaerobic fermentation for 20 days, and then add aerobic bacteria to carry out fermentation for 10 days. The fermented mixture is dried and dehydrated by using the tail gas produced by rotary kiln roasting, and the product long-acting ...

Abstract

The invention discloses a method for producing a long-acting soil conditioning agent by using potassium feldspar and organic waste. Potassium feldspar, limestone, aid and coal are used as raw materials in the method. The method comprises the following steps of: roasting the crushed raw materials in a rotary kiln by adding the coal, and cooling and milling the roasted raw materials; and mixing the powder and the organic waste such as animal excrement in a farm and the like, performing anaerobic and aerobic continuous fermentation step by step, performing partial dehydration, and thus obtaining a finished product. The produced long-acting soil conditioning agent contains a certain amount of nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, soluble silicon, humic acid and the like, so the soil conditioning agent can effectively improve the soil and provides nutritional components for crops for long time. The soil conditioning agent can be directly applied, and can also be applied with chemical fertilizers. According to the method for producing the long-acting soil conditioning agent by using the potassium feldspar and the organic waste, the production raw materials are mineral in the nature and waste in the farm, the raw materials are extremely rich and cheap, and the production process is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a production method of a soil conditioner, in particular to a method for producing a long-acting soil conditioner by using potassium feldspar and organic waste. Background technique [0002] Plant growth mainly needs 16 kinds of essential nutrients, among which potassium belongs to the third place in terms of importance. In my country's agricultural fertilization, the ratio of nitrogen, phosphorus and potassium has been out of balance for a long time, which is lower than the reasonable level, especially the imbalance of potassium fertilizer is more serious. my country is a country that is extremely short of soluble potassium resources. The potassium salt reserves in Qinghai are 116 million tons (calculated by KCl), and the average grade of KCl in potassium-rich brine layers is 1.29%. %. my country's per capita soluble potassium reserves are only 1 / 14 of the world level; far from meeting the needs of agricultural development. ...
