Embodiment 1
[0036] Embodiment 1 Preparation of a kind of polysaccharide trace element fertilizer is processed according to the following steps:
[0037] 1) Mix 4 kg of molasses dregs, 3 kg of tung bran, 4 kg of bran bran, and 3 kg of soybean dregs, add 0.1 kg of bacteria, and ferment for 36 hours to make organic fermentation raw materials;
[0038] 2) Crush the organic fermentation raw materials, add 300kg of humic acid complexed rare earths and 100kg of polysaccharide complexed trace elements and stir well to form decomposed raw materials;
[0039] 3) Put the molasses into the storage tank to ferment for 48 hours, measure 1100kg of molasses with a graduated measuring tank, and put it into a clean reactor;
[0040] 4) Molasses heating: turn on the reactor stirrer, and turn on the jacket steam valve to heat to 60°C;
[0041] 5) Synthesis of polysaccharide trace element complexes: Slowly add 200kg of manganese sulfate monohydrate into the kettle, and finish in 10-15 minutes; then slowly add ...

[0051] 5) Synthesis of polysaccharide trace element complexes: Slowly add 200kg of manganese sulfate monohydrate into the kettle, and finish in 10-15 minutes; then slowl...
Embodiment 3
[0057] Soil for test: Bamboo spinach was planted in Toutang Town, Tianyang District, Baise City in August 2019, and its pH value was tested to be 5.3. The main components of the soil are as follows: organic matter 17.9g / kg, alkaline nitrogen 105mg / kg, Available phosphorus 203.1mg / kg, available potassium 207mg / kg. Experimental design: 4 treatment areas were set, each area was 16 square meters, and each area was repeated 3 times, 12 areas in total. The 4 processing areas are processed as follows:
[0058] Treatment 1: 2 kg of the polysaccharide trace element fertilizer of Example 1 before sowing; 2 kg of the polysaccharide trace element fertilizer of Example 1 was applied 15 days after sowing.
[0059] Treatment 2: Apply 2 kg of Yangfeng compound fertilizer before sowing; 15 days after sowing, apply 2 kg of Yangfeng compound fertilizer.
[0060] Treatment 3: 2 kg of urea, monoammonium phosphate, calcium magnesium phosphate fertilizer, and potassium chloride before sowing; 2 kg...
