A kind of vegetation water and its preparation method and application
Technical field:
The invention belongs to proportion of crop planting field and field of environment protection, the application being specifically related to a kind of vegetation water and preparation method thereof and improving looks farm crop and prepare in green manure and field of Environment Protection.
Background technology:
At present, China is subject to havoc due to agroecological environment, causes diseases and pests of agronomic crop more and more serious, the blade face of farm crop and Ye Se are subject to disease and pest and destroy and crop yield is sustained a loss, and selling price is also low, especially vegetable crop, this causes plant husbandry to suffer heavy losses.In addition, the abuse of chemical pesticide and chemical fertilizer and other not environmentally fertilizer also causes Agro-ecology crisis to aggravate, and directly threatens the Sustainable development of people's health and economic society.Therefore, how crop blade face is beautified by the disease and pest of environmental-friendly plant material minimizing crop; In addition, how to research and develop new plant green manure to replace chemical fertilizer and other fertilizer not environmentally, this all becomes the study hotspot problem of the present age and even following long duration.
Summary of the invention:
The object of this invention is to provide a kind of vegetation water and its preparation method and application.Vegetation water of the present invention can promote crop growth and significantly volume increase, the disease and pest of remarkable minimizing farm crop, make leaf look more emerald green, reach the effect of plant leaf beauty treatment, in addition, vegetation water of the present invention can also replace chemical fertilizer and partial chemical agricultural chemicals, is prepared into plant green manure, improve crop mouthfeel, thus improve the procurement price of crop.
Vegetation water of the present invention, is characterized in that, is prepared by following steps:
The fresh branches and leaves material of every 20g narrow leaved tea tree tree (Melaleucaalternifolia), more than 50-60g Leaf of Indigowoad (dry medicinal material) (IsatisindigoticaFortune) and the fresh leaf vegetables of 20-25g, adding distil water 1200mL, boil, add water again and be transferred to 1200mL, discard residue, gained supernatant liquor is vegetation water.
More than described fresh leaf vegetables, more than the fresh leaf vegetables being preferably cabbage heart and/or Plantula Brassicae chinensis.
Described boils, and is preferably warm fire and boils 25-30min.
Vegetation water of the present invention is promoting the application in crop growth and farm crop beauty treatment.
The application of vegetation water of the present invention heavy metal element in the heavy metal prepared in green manure and minimizing solution and fixing soil.
Described farm crop, are preferably Plantula Brassicae chinensis, cabbage heart, peanut, leek, logical heart dish, capsicum, eggplant melon, fresh kidney beans, bitter wheat dish, purple perilla and leaf mustard.
The present invention is found by normal experiment method, compared with the control, crop yield through vegetation water process significantly increases more than 15% (P<0.01), blade disease and pest significantly reduces more than 50% (P<0.01), find that blade comparison illumination is aobvious fresh and tender emerald green and mouthfeel is better, growth prolongation more than 5 days (if extend 5 days results, yield increased increase is more), and safe to eat.This is because vegetation water contains a large amount of abundant organism, the multiple nutrient that crop needs can be decomposed into gradually, therefore vegetation water both can serve as beauty liquid to beautify crop, also can serve as the cheap plant-sourced green manure of crop, thus replace present chemical fertilizer and part agricultural chemicals and part fertilizer.
Vegetation water of the present invention can significantly reduce containing the cadmium in high density heavy metal cadmium and plumbous solution and plumbous content, significantly reduces the cadmium ion (Cd of 95% (P<0.01) in solution respectively
2+) lead ion (Pb of content and 65% (P<0.01)
2+) content; Meanwhile, 15% (P<0.05) of cadmium content in vegetables body and more than 60% (P<0.01) of lead content can significantly be reduced.Crop yield through vegetation water process significantly increases more than 15% (P<0.01).This is because the Leaf of Indigowoad decoction liquor in vegetation water has alkalescence, its OH
-with free cadmium ion (Cd in sewage solution and the soil solution
2+) and lead ion (Pb
2+) form stable throw out or polymer, thus make cadmium and plumbous content in minimizing solution, and heavy metal in fixing soil, also make crop be difficult to ionic condition and absorb cadmium ion and lead ion; Meanwhile, the Leaf of Indigowoad decoction liquor with alkalescence can make soil pH increase, and Blaylock etc. study discovery, and as soil pH ﹥ 7.5, plumbous solubleness reduces, and crop difficulty can be made to absorb plumbous, thus makes its content lower than contrast.
The using method of vegetation water of the present invention is: by appropriate vegetation water through dilution 5-10 doubly, spray the leaf of crop, stem and root.
Vegetation water low cost of the present invention, low price, can replace chemical fertilizer and partial chemical agricultural chemicals, be prepared into plant green manure, serve as crop beauty liquid, improve crop mouthfeel, thus improve the procurement price of crop.Because narrow leaved tea tree tree arbitrarily can be planted in rural area, therefore with low cost, environmental protection and facilitate feasible, can avoid at present because the ecological hazard brought abused by chemical fertilizer and agricultural chemicals; In addition, vegetation water contains a large amount of gas chromatographies, because the organism increasing soil can improve soil, strengthen the mobility of soil microorganisms, organism also can produce adsorption to some pollutents such as remains of pesticide and heavy metal in soil, thus alleviate the toxic action of these venomous injurant confrontation soil and farm crop, be achieve many things at one stroke.
This method Sustainable development, set up the bridge that connects Traditional Scientific and postmodern science, its meaning is far-reaching, great, and will welcome the environmental protection type agricultural revolution that take material of vegetable origin as impellent, the development of promotion low-carbon agriculture, promotes the well-being of mankind.
