Problems solved by technology

A large-scale olive processing enterprise currently produces about 45,000 tons of olive pomace each year. The discarded olive pomace is mainly disposed of through a simple landfill, which takes up a lot of land and produces a lot of seepage and odor. Cause environmental pollution and waste resources
The discarded olive pomace produced by fruit juice processing is large in size, high in water content, and serious in environmental pollution, requiring effective treatment urgently
Olive pomace is rich in water, pectin, cellulose, minerals, and a small amount of protein, essential oil and flavonoids. The relevant departments of the country have conducted a lot of research on the harmless treatment and resource utilization of olive pomace. Including the extraction of essential oils, pectin, pigments, cellulose and flavonoids, which cannot effectively process large quantities of pomace

Abstract

The invention discloses a soil water retention conditioning agent prepared from olive wastes. The soil water retention conditioning agent comprises following raw materials in parts by weight: 40 to 50parts of olive dregs, 20 to 30 parts of olive branch wood vinegar, 10 to 20 parts of organic chelating agent, 5 to 10 parts of sodium dodecyl sulfonate, 4 to 8 parts of chitosan, 1 to 5 parts of gamma-polyglutamic acid, 5 to 15 parts of polyvinyl acetate, 5 to 10 parts of ammonium sulfate, and 1 to 5 parts of crosslinking agent. The water retention conditioning agent has a three dimensional net structure, has a strong water-association effect, can improve the soil structure, improves the tightness and penetration performance of soil, increases the water stable particles and porosity of soil,optimizes the breathability of soil, adjusts the soil between a water deficient state and a water sufficient state to keep the water balance of soil, promotes the growth of microbes in the soil at thesame time, and improves the utilization rate and cycle speed of organic matters in the soil.

Description

technical field [0001] The invention relates to a soil water retention agent, in particular to a soil water retention regulator prepared from olive waste. Background technique [0002] Soil is the most basic means of production for human beings and the material basis for human survival. In our country, land resources are not only very limited, but also a considerable proportion of soils have obstacle factors due to soil-forming factors or human factors, including erosion, poor texture, poor structure or arability, salinity, acidification, toxic substance pollution, There are bad soil layers in the soil that hinder the growth of plant roots, too much or insufficient soil moisture, low fertility or imbalance of nutrients, etc. Typically, these barrier soils are difficult to use, but in recent years amending them with soil conditioners has shown better results. However, the cost of raw materials of existing soil water retaining agents is relatively high. On the other hand, i...
