摘要:
Compressed mixtures of blends of coconut coir pith and selected horticulturally acceptable non-coir/non-peat materials such as composted yard waste; composted bark; composted manure; sand; peat humus; composted agricultural waste; composted animal byproducts; treated sewage sludge; animal and/or vegetable-based landfill waste; wood and lignocellulose derivatives; vermiculite; perlite, glass beads; foamed plastics, and mixtures thereof are prepared in a manner such that, upon decompression, a total volume of decompressed coir pith and decompressed non-coir/non-peat material is produced which exceeds the sum of the initial volumes of coconut coir pith and non-coir/non-peat material in the blends.
摘要:
The present invention relates to methods of improving germination rates of plants or crops, and of preventing or arresting water evaporation loss from targeted soil areas by use of soil additives, which allow for improved water utilization by crops, plants, grasses, vegetation, etc.
摘要:
Knot rejects from chemical pulping processes are subjected to acid hydrolysis or an enzymatic hydrolysis treatment. The resultant hydrolysate is enriched with glucose, representing a value-added raw material for products using hexoses. The residue, separated from the said hydrolysate after the acid hydrolysis or enzyme treatment, consists of mainly knots or chips. The residue has a much improved aesthetic appearance which can be readily used as value-added raw materials for mulch or similar applications. The residue could also be extracted to obtain high value antioxidants and other nutraceutical chemicals such as lignans or can be utilized according to currently known practices including recooking, burning and depositing.
摘要:
The invention concerns a method for accelerated degradation of mulch paper, whereof the cellulose fibres are impregnated with a hydrophobic resin providing said paper with resistance to poor weather conditions. Said method consists in spraying on the paper an enzymatic solution for degrading both the resin and the cellulose. The invention also concerns mulch paper for implementing said method.
摘要:
This invention relates to a preparation and a method for reducing the consumption of water in agriculture and other activities in which plants are cultivated, and which at the same time helps to reduce the seepage of nutrient-rich, fertiliser-saturated water into the ground water. More particularly, the invention relates to an electronegative, antioxidising powder mixture which, upon application to an upper layer of soil, is capable of forming a biologically degradable membrane in the upper layer of soil, preferably comprising the surface of the soil and a biologically active zone for root and plant formation, wherein the membrane has a combined effect in that it increases the retention time of water and nutrients in the root zone, has an antioxidising effect on the environment in order to combat ozone and other free radical induced damage to the vegetation, and regulates the albedo of the top soil layer so that the temperature in the root zone is held within the temperature at which the plants thrive. This is obtained by a powder mixture comprising a water-soluble, dried and ground organic raw material from marine brown algae with at least one added pigment, and that the powder mixture is exposed to an E-field of negative polarity so that the material at least is saturated with electrons.
摘要:
The invention relates to a biologically degradable ground cover consisting of a nonwoven-type material which is matched to the profile of the surface of the soil and is obtainable by applying an aqueous solution of a water-soluble alginate and biologically degradable fibres which are distributed in water to the soil and using metal cations to crosslink the water-soluble alginate, which is characterized in that the metal cations comprise a mixture of metal cations with a valency of two and with a valency of higher than two. The invention also relates to a dry product for use in forming a biologically degradable ground cover, and in particular the dry product comprises 20-98% by weight of biologically degradable fibres and 0.5-20% by weight of water-soluble alginate, as well as fillers up to 100%. The invention also relates to the method for forming a ground cover on the surface of an area of ground.

A biodegradable fibrous support for mulching of the soil comprises a reinforcement in the form of a grid made of biodegradable polymers and either maintained on the whole or part of support face(s) or incorporated into the whole or part of the mass of the support.
摘要:
A method of manufacturing a multi-purpose functional agricultural mulching paper (1) is disclosed. The method comprises steps of (a) providing a papermaking material, (b) treating the papermaking material to form a cleaned paper pulp, and (c) adding at least one functional additive into the cleaned paper pulp and treating the cleaned paper pulp to form the multi-purpose functional agricultural mulching paper (1). The multi-purpose functional agricultural mulching paper (1) of the present invention can be applied in weed control, pest control, bacterial control, plant disease control, growing seedling, fertilizer supply and seed sowing to increase the economic benefits.
