Abstract
The invention relates to the application of pesticide residue degradation bacteria of pyrethroid on modifying the crop quality, belonging to microbiological fertilizer field. It takes the pesticide residue degradation bacteria strain LFJS3-9 as bacteria for production, dilutes it for 15-20 times according to consumption of 30-75kg / hectare, and sprays on crop surface or to soil in a sunny day. It is usually used after the last pesticide utilization, and the effect would be better if used many times or during crop best growing period. It is determined that said bacteria contains many kinds of nutritional components. The invention is characterized by low cost for production and utilization, dramatic crop quality modification, suitability for farm product production and processing in modern agricultural production, and the utilization can be widely spread on industrial crop such as tea and vegetable and cereal crop such as rice.
Description
One, technical field
The present invention relates to the application of degrading pyrethroid pesticide residue bacterium in improving crops quality, belong to the microbial manure field, be to utilize method of microorganism, improve the soil and improve the quality of crops, be applicable to modern agriculture produce in the production and the processing of high quality agricultural products.
Two, technical background
The history that the agricultural of China has been passed by surplus in the of 5000 year.In the tradition, peasant's plant husbandry and animal husbandry are combined closely, and keep soil nutrient balance by application of organic fertilizers, have followed the natural moving law of ecosystem process, have guaranteed sustainable development of agriculture.But since the 1950's, the use that growing population presses for new agricultural technologies such as chemical fertilizer, agricultural chemicals input and new varieties improvement satisfies the demands to produce more food, and this has promoted the development of intensive agriculture.Over surplus past 50 year, the chemical fertilizer application total amount of China is increased to 4,412 ten thousand tons in 2003 from 0.6 ten thousand tons (pure nutrients) in 1949, and the applying quantity of chemical fertilizer of unit are is from the 0.75kghm of nineteen fifty-two
-2339.3kghm by 2003
-2, some developed areas even near 700kghm
-2In addition, 132. ten thousand tons of (10.2kghm of agricultural chemicals usage amount in 2003
-2), cropping index 118.9 (subtropical zone 140~200).By the input of these agricultural chemicals and the improvement of agriculture production technology level, promoted the raising of grain yield greatly just.Roughly, chemical fertilizer accounts for about 50% in the effect that improves on the grain yield.Integrate and see, high investment and high strength utilization are the topmost characteristics of China's intensive agriculture activity in production.At present, total consumption of China's chemical fertilizer, agricultural chemicals occupies first of the world, and the unit are consumption is respectively 3 times and 2 times of world average level.From the national conditions of China, in following a period of time, for ensureing food security, the input of the high strength utilization of soil and a large amount of agricultural chemicals is still inevitable.
But, the modern agriculture that with the intensive utilization is feature when having obtained great achievement, the resource environment problem that it brought and the potential threat of human survival also manifested day by day.Studies show that in a large number the intensive agriculture pattern externally drops into down has higher productive potential, but ecosystem composition is single, system productivity and stable continuing need great cost just can keep.Along with the increase nutrient yield-increasing efficiency of applying quantity of chemical fertilizer obviously descends, the grain yield of every kilogram of chemical fertilizer application volume increase drops to 8~10kg at the beginning of 21 century from 50~60kg of the 1950's.Particularly the developed area intensive agriculture utilizes the degree height, and it is quite serious to use for a long time available nutrient excess accumulation and nutrient imbalance phenomenon that chemical fertilizer causes in a large number, and this situation will continue; A large amount of agricultural chemicals, weed killer herbicides of using make also that the residual quantity of these chemicals increases day by day in the agricultural land soil.All these intensive agriculture activities in production have all produced strong interference and huge pressure to soil ecosystem itself, and resource environment has been constituted serious threat.The arable land degenerate problem is serious day by day, and crops quality descends, and has had a strong impact on increasing peasant income.
The microbe soil improving technology is with fertilizer and impel the micropopulation mixture of soil nutrient rapid release to impose in the soil.Microorganism can be decomposed organic matter fast and efficiently and be quickened self growth and breeding in soil, the ammoniacal nitrogen that plant can absorb is fixed and be converted into to airborne molecular nitrogen, simultaneously P insoluble in the soil, K are decomposed into the element of solubility, thereby be easy to improve the soil with this into the plant absorbing utilization; In addition, behind crop harvesting, directly effective microbe colony is sprayed on stubble, face of land stubble is up and down decomposed rapidly, with and reach and increase soil fertility, the structure of improving the soil, fully keep and utilize the purpose of soil moisture.
Crop can also absorb nutrition by cauline leaf part (especially blade) except that root system.To absorb the phenomenon of nutrition be exactly the exoroot nutrition of crop to this non-root system during plant growth, is called foliage fertilization, generally alleged foliar application just to the measure of the trophosome surface applied fertilizer except that crop root.Foliar application has following characteristics: avoid nutrient fixing or conversion in soil, directly supply with crop and absorb; Nutriment absorbs fast, and fertilizer efficiency is good; With strong points; Improve utilization rate of fertilizer; The deficiency that additional root absorbs nutrient component etc.
Because action of microorganisms contains multiple organic nutrition composition and elements such as Mg, Ca such as amino acid, vitamin as in the microbial inoculum of microbial manure, they exist with the form of complex compound, and these materials have facilitation preferably for the growth of crops.Some researchs and reagent are used and are shown that microbial inoculum is directly made foliage-spray, and nutrient component can be absorbed by crop rapidly, keeps the nutrient balance of plant corpus, can improve crop yield and improvement crop quality.
Bacterial strain LFJS3-9 is a strain pyrethroids pesticide degradation bacterium, and the microbial inoculum of this bacterial strain and production thereof is applied for a patent, and application (patent) number is 200510022548.7, publication number: CN1800354; Open day: 2006.07.12.Be preserved in Chinese microorganism strain on October 12nd, 2005 and preserve administration committee common micro-organisms center, culture presevation number is CGMCC NO.1477.This patent provides a kind of pyrethroid pesticide remained degradation bacteria and degradation bacterial agent eliminated, and bacterial strain uses therefor is LFJS3-9, pseudomonas (Pseudomonas sp.).Degradation bacteria zymotic fluid (10
10Cfuml
-1) showing in the small plot experiment in tea place: after degradation bacteria is used 5 days, being 85.16% to the degradation rate of Biphenthrin, to the degradation rate 87.01% of cypermethrin, is 87.79% to the degradation rate of decis.The application aspect the improvement crops quality of above-mentioned patent degradation bacteria and degradation bacterial agent is not disclosed in the prior art.
Three, summary of the invention
Technical problem the object of the present invention is to provide a kind of method that improves crops quality, is to utilize method of microorganism, improves the soil, and improves the multiple nutritional components content in tealeaves, paddy rice, the vegetables, thereby improves the quality of crops.Be applicable to the production and the processing of high quality agricultural products in the modern agriculture production.
Technical scheme
