Biological organic nutrient soil and preparation method thereof

Abstract

The invention provides biological organic nutrient soil, which comprises, by weight, 80-100 parts of coconut residuum, 40-50 parts of peat soil, 10-20 parts of perlite, 5-10 parts of vermiculite, 20-30 parts of a decomposed biological organic fertilizer, 5-10 parts of attapulgite, 4-6 parts of tobacco extract, 0.1-0.3 part of tea saponin, and 4-6 parts of a composite microbial agent. The coconut residuum and peat soil are added into the nutrient soil, so that the nutrient soil has good air permeability and water retention property; the biological organic fertilizer is added to serve as a nutrient source in the nutrient soil, the nutrient elements are comprehensive, the fertilizer efficiency lasts long, and nutrients can be continuously provided for seedlings. The biological organic nutrient soil is prepared by mixing pure natural materials, the prepared nutrient soil is environmentally friendly and nontoxic, and the raw materials used in the formula and the preparation method are simple, and the nutrient soil is convenient to use and free of peculiar smell; the biological organic nutrient soil is good in soil structure, good in air permeability, good in water and fertilizer retention performance and good for growth and development of seedlings.

Description

technical field [0001] The invention relates to the technical field of nutrient soil, in particular to a bio-organic nutrient soil and a preparation method thereof. Background technique [0002] The area of ​​protected cultivation and family balcony planting in my country is expanding year by year, and the phenomenon of continuous cropping obstacles in protected cultivation and balcony planting is becoming more and more serious, which greatly restricts the sustainable development of protected agriculture and balcony planting. One of the effective cultivation measures to overcome continuous cropping obstacles is soilless cultivation. However, the high input cost of soilless cultivation limits its large-scale application, so it is urgent to research and develop cheap and simple cultivation methods and techniques to overcome continuous cropping obstacles. Nutrient soil cultivation technology is a cultivation technology in which non-natural soil is used as a substrate. It is ma...

Problems solved by technology

[0003] In the process of transplanting seedlings, due to changes in the growth environment, changes in soil structure, and reduced nutrient supply intensity, it is easy to cause the death of transplanted plants. The nutrient soil currently on the market is suitable for the cultivation of small plants such as potted plants. It is relatively single and cannot meet the transplantation requirements of various plants

Traditional nutrient soil is generally added to the field soil with traditional elemental fertilizers, compound fertilizers, etc. The nutrients are released quickly, and most of the nutrients in the fertilizer are easily leached and volatilized, resulting in low plant utilization. After a period of use, Fertilizer efficiency will decrease, and regular fertilization is required

In addition, there are many types of nutrient soil on the market, and the quality of the products is uneven. Usually, there is no reasonable ingredients, the nutritional elements are unbalanced, and a variety of chemical fertilizers and pesticides are added. It does not meet the requirements of organic products, and has not passed strict disinfection and sterilization. , is not conducive to the normal growth and development of seedlings
