Embodiment 1

[0022] Embodiment 1: The experiment of compound fertilizer containing fenugreek gum and seaweed on potted green vegetables.

[0023] The basic nutritional fertilizer comprises the following components in mass percent: urea 30.1% (14.1% of the nitrogen element content in urea), 42.0% of the double superphosphate (the content of the phosphorus element in the double superphosphate is 9.7%), potassium chloride 27.9% % (the content of potassium element in potassium chloride is 17.3%).

[0024] The compound fertilizer containing fenugreek gum and seaweed is obtained by adding 0.7wt% of fenugreek gum and 0.5wt% of seaweed extract on the basis of the above-mentioned basic nutrient fertilizer, mixing evenly and drying.

[0025] The above-mentioned compound fertilizer containing fenugreek gum and seaweed was used in the experiment of potted green vegetables. The experiment was carried out in the Engineering College of Nanjing University of Technology from November 2016 to January 2017. ...

Abstract

The invention discloses a slowly-released synergistic compound fertilizer which comprises a basic nutrient fertilizer, bottle gourd Pakistan rubber and a seaweed extract, wherein the basic nutrient fertilizer contains nitrogen, phosphorus and potassium elements. The bottle gourd Pakistan rubber accounts for 0.5-2% of the weight of the basic nutrient fertilizer, and the seaweed extract accounts for0.5-2% of the weight of the basic nutrient fertilizer. The slowly-released synergistic compound fertilizer is provided with the bottle gourd Pakistan rubber, the release speed of active substances ofthe fertilizer can be controlled to some extent, the fertilizer is slowly released, the bottle gourd Pakistan rubber is a plant polysaccharide and can be decomposed, absorbed and utilized by soil microorganisms such as bacteria, the bottle gourd Pakistan rubber is environmentally friendly, and fertilizer damage to the soil is reduced to a great extent. The seaweed extract is rich in various active substances such as organic matters, carbohydrate, amino acid, inorganic salt, vitamin and plant hormones. The bottle gourd Pakistan rubber and the seaweed extract have a certain synergistic effect,the bottle gourd Pakistan rubber has excellent chelation function, the fertilizer and seaweed can be wrapped together, interaction time is prolonged, and the utilization rate of the fertilizer is increased.

Description

technical field [0001] The invention belongs to the technical field of biological fertilizers, in particular to a slow-release and synergistic compound fertilizer containing fenugreek gum and seaweed extract. Background technique [0002] Agriculture is the primary industry of our country and has been the foundation of the national economy since ancient times. As we all know, the grains and vegetables we eat all come from agricultural production and processing. Rural areas are where raw materials are produced. In 2016, grain prices were lower than in previous years, but the price level was rising. The main reason was that grain input was not directly proportional to output. For modern agriculture, herbicides, chemical fertilizers, various hormones, and machine farming are unavoidable for various organisms, soil compaction, poisoning, and water pollution. Whenever it rains, soil erosion is very serious, and the soil is often shed. With the development of the times, the use ...
