Problems solved by technology

The topdressing period of Salvia miltiorrhiza is generally in the flowering period. Due to the flowering period of Salvia miltiorrhiza, the ridges of Danshen have been closed, so it is very inconvenient to topdress. Digging and topdressing are easy to damage the roots; the utilization rate of fertilizer is low
At present, it is not possible to fertilize Danshen at one time according to the growth and development rules of Salvia miltiorrhiza and the content of nutrient elements in the soil to meet the nutrient requirements of Salvia miltiorrhiza throughout the growth period.

Embodiment 1

[0031] The organic-inorganic long-acting Danshen special compound fertilizer consists of 12 kg of large-grain urea, 32 kg of slow-release sulfur-encapsulated urea, 16 kg of diammonium phosphate, 20 kg of potassium sulfate, 0.5 kg of manganese sulfate, 1.2 kg of zinc sulfate and 26 kg of organic fertilizer. Particles are mixed; the organic fertilizer particles are made from decomposed pig manure and straw; the pig manure: straw = 2:1 parts by weight; The straw is made by adding pig manure and 5% polyisocyanate by weight of the straw through direct extrusion granulation and disc polishing.

Embodiment 2

[0033] The organic-inorganic long-acting Danshen special compound fertilizer consists of 14 kg of large-grain urea, 28 kg of slow-release sulfur-encapsulated urea, 19 kg of diammonium phosphate, 18 kg of potassium sulfate, 1.2 kg of manganese sulfate, 0.5 kg of zinc sulfate and 30 kg of organic fertilizer. Particles are mixed; the organic fertilizer particles are made from decomposed pig manure and straw; the pig manure: straw = 2:1 parts by weight; The straw is made by adding pig manure and 9% polyisocyanate by weight of the straw through direct extrusion granulation and disc polishing.

Embodiment 3

[0035] The organic-inorganic long-acting Danshen special compound fertilizer consists of 13 kg of large-grain urea, 30 kg of slow-release sulfur-encapsulated urea, 18 kg of diammonium phosphate, 19 kg of potassium sulfate, 0.8 kg of manganese sulfate, 0.8 kg of zinc sulfate and 28 kg of organic fertilizer. Particles are mixed; the organic fertilizer particles are made from decomposed pig manure and straw; the pig manure: straw = 2:1 parts by weight; The straw is made by adding pig manure and 7% polyisocyanate by weight of the straw through direct extrusion granulation and disc polishing.

Abstract

The invention provides a compound fertilizer special for organic and inorganic long-acting salvia miltiorrhiza. The compound fertilizer special for the organic and inorganic long-acting salvia miltiorrhiza is prepared by mixing, by weight, large-granule urea 12-14 parts, slow-releasing sulfur-clad urea 28-32 parts, diammonium phosphate 16-19 parts, potassium sulphate 18-20 parts, manganese sulfate 0.5-1.2 parts, zinc sulfate 0.5-1.2 parts and organic fertilizer granules 26-30 parts. The organic fertilizer granules are prepared by pig manure and straws. The weight ratio of the pig manure to the straws is 2:1. A binding agent occupying 5-9% by weight of the pig manure and the straws is added into the pig manure and the straws to be directly extruded and granulated to prepare the organic fertilizer granules. The binding agent is polyisocyanate.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for long-acting salvia miltiorrhiza combining organic fertilizers and inorganic fertilizers. Background technique [0002] Salvia ( Salvia miltiorrhiza Bunge.) is the dried root of the perennial herbaceous plant of the Salvia family. It is one of the 40 largest-selling traditional Chinese medicinal materials in my country. Modern research shows that Danshen can dilate coronary arteries, increase coronary flow, improve cardiac ischemia, infarction and cardiac function, adjust heart rhythm, inhibit thrombosis, and lower blood lipids. [0003] With the in-depth study of the pharmacology of Danshen, the range of application of Danshen is becoming wider and wider, and the demand is increasing year by year. Wild Danshen resources alone cannot meet the demand. In recent years, the market supply is very short, and the main production areas of Danshen in the cou...
