Definitions

  • the invention described below lies in the field of agriculture and forestry and horticulture and relates to a method for improving plant growth by stimulating the microorganisms which live in the substrate on which the plants grow.
  • the invention therefore relates to the use of phospholipids to improve plant growth, which consists in adding phospholipids to the substrate on which the plants grow or are supposed to grow and thereby stimulate the microorganisms living in the substrate.
  • phospholipids lecithin, lecithin hydrolyzates or chemically modified lecithins are preferably used.
  • the unexpected effect of the phospholipids on the microbial soil flora manifests itself, among other things, in the fact that organic soil is present Compounds and plant residues are broken down more quickly, resulting in an increase in soil bacteria.
  • the composting process taking place in the soil is accelerated and dead plant material is returned to the biological cycle more quickly.
  • the aeration of the soil or the substrate on which the plants grow is improved and the water balance is made more uniform. It is believed that these are the main causes for the improvement in the growth of the plants grown on these substrates.
  • the phospholipids used according to the invention are amphiphilic substances which are obtained from plant or animal cells.
  • Preferred phospholipids are the glycerophospholipids, which are usually also referred to as lecithin.
  • the sphingophospholipids are less preferred.
  • Known and usable substances here are the diacylphospholipids, phosphatidylcholines, phosphatidylethanolins, phosphatidylinositols, phosphatidylserines, phosphatatidylglycerols, phosphate idylglycerol phosphates, diphosphatidylglycerol, N-acylphosphatidylethanolamine amine.
  • phosphatidylglycerides which are commercially available as vegetable or animal lecithins and zephalins. These preparations are mostly obtained from oils such as corn oil or cottonseed oil or soybean oil.
  • the enzymatically hydrolyzed glycerophospholipids are preferred which have a more hydrophilic character due to the elimination of a fatty acid ester. The only exceptions are products that have lost their phosphoric acid residue due to the enzymatic hydrolysis.
  • the phospholipids are completely biodegradable to form CO2, H2O and biomass, with the result that in the case of the invention
  • the process does not accumulate any inert or ecotoxicologically questionable degradation products in the soil.
  • the phospholipids themselves migrate slowly in the soil and are therefore not washed out into the groundwater. They are also non-toxic, so that their use is also possible for this reason.
  • liquid preparations are usually used. This takes place in particular in such a way that 0.5 to 30 g, preferably 1 to 20 g, of phospholipid are applied in dilute aqueous preparation per m ⁇ substrate surface.
  • the aqueous preparation preferably contains 1 to 20 g, in particular 2 to 9 g, of phospholipid per liter.
  • the aqueous preparation can be prepared in this form immediately before use, but it has proven expedient to carry out the preparation of this preparation intended for use in such a way that a more concentrated preparation is first diluted with water for the users ⁇ dung concentration is set.
  • This can be a solid concentrate, for example in powder or granule form; however, liquid concentrates are preferably used.
  • Suitable anionic surfactants are primarily soaps, but alkyl sulfates, in particular fatty alcohol sulfates, can also be used.
  • Anionic surfactants based on petrochemicals such as, for example, alkylbenzenesulfonate or alkyl ether sulfates, are less suitable.
  • Partial esters of phosphoric acid with fatty alcohols are also suitable, and in particular corresponding partial esters with straight-chain fatty alcohols.
  • the esters of shorter-chain fatty alcohols for example those with C 1 -C 10 alcohols, are particularly suitable here.
  • alkyl phosphates with longer fatty alcohol residues ie C12 to C24, can also be used.
  • Fatty alcohol ether phosphates can also be used. These are phosphoric acid partial esters of ethoxylated fatty alcohols, the fatty alcohols having 8 to 24 carbon atoms and being ethoxylated with 1 to 10 mol, preferably 4 to 6 mol, of ethylene oxide per mol of fatty alcohol.
  • Preferred nonionic surfactants are alkyl glycoside compounds, which have preferably been prepared from straight-chain fatty alcohols with at least 8 carbon atoms.
  • Suitable alkyl glycoside compounds contain, for example, fatty alcohol residues in the range from C ⁇ to Ci ⁇ , in particular C ⁇ o to C Q and have an average degree of polymerization of the oligoglycoside residues in the range from about 1.2 to 5.
  • Corresponding alkylglycoside compounds with a DP value of about 1.5 to 5, in particular in the range of the HLB values of about 10 to 18, can not only be regarded as effective surfactant additives of the O / W type, they characterize them is also characterized by a special biocompatibility, which is partly due to its comparatively rapid degradability.

  • Suitable fertilizer ingredients are inorganic and organic substances which, either immediately or after chemical decomposition in the substrate on which the plants grow, the elements required by the plants, in particular nitrogen, phosphorus, potassium, magnesium but also trace elements such as iron, manganese, Provide zinc, copper, molybdenum and boron in a form that can be absorbed by the plants.

In the case of dense crops, for example also in lawns, it is also readily possible to apply the phospholipid preparations in the irrigation process in such a way that wetting of plant surfaces also takes place in the meantime, provided the preparations are composed such that the plants are damaged, for example, when the preparation dries out.

Three boxes each were treated with a solution according to the invention and with a comparison solution with the same nitrogen and phosphorus content.

  • the solution used as a comparison was also prepared by dilution with water in a ratio of 1:70 from a concentrate which, however, did not contain any phospholipid but instead consisted only of monoammonium phosphate, urea and water with the same phosphorus and nitrogen content. In both cases, the application rate was 600 ml per box once a week, so that 882 mg of N and 203 mg of P2O5 were made available to each box per week.
  • test plants were scored weekly. For almost the entire test period, the plants in the boxes treated according to the invention showed vigorous growth, more intense leaf coloring and greater flowering capacity than the plants in the comparison boxes.

Abstract

La croissance de végétaux est améliorée par adjonction de phospholipides au substrat sur lequel lesdits végétaux se développent ou doivent se développer. Ce phénomène est certainement lié à une stimulation des micro-organismes vivant dans le substrat. Les phospholipides concernés sont avant tout la lécithine, les hydrolysats de lécithine et les lécithines modifiées chimiquement, qui sont ajoutés de manière générale sous forme de préparation aqueuse diluée, à raison de 0,5 à 30 g par mètre carré.
