Abstract
The present invention relates to a method for preparing a pollution-free germicide by using plant liquid extract. Said invention uses a Chinese medicinal herb - Shanjiangzi as raw material, and makes its seed, leaf and stalk pass through such processes of mixing, distillation and concentration, and adds sorbitol, and then makes them into the invented aldehyde-containing aqueous emulsion whose aldehyde content is 10-60%. Said germicide can control several plant diseases, is non-toxic for human and animals, and has no pollution to environment.
Description
The present invention relates to a kind of method of making nuisanceless bactericide by plant extraction liquid.
The bactericide that is used to prevent and treat corps diseases at present mostly is chemical pesticide greatly, as tpn, topsin, carbendazim, tmtd, zineb etc.Though the chemical pesticide bactericidal effect is good, cost is higher, particularly has certain toxicity, to air, soil, water quality and the agriculture and forestry product that used these agricultural chemicals, pollution is to a certain degree arranged all, influences the healthy of people.The crop bactericide (patent No. ZL881005697.9) of Ye Zhengfan invention is to be the bactericide of main component with fruit of a cubeb litsea tree pin oil concentrated filtrate, environmentally safe, can be regarded as public nuisance-free agricultural chemicals, but raw material is not abundant especially, production cost is also higher relatively, so bactericide that neither be very good.
The object of the present invention is to provide a kind of method of making nuisanceless bactericide by plant extraction liquid.This method program is simple, raw material is easy to get, and made bactericide bactericidal effect is good, and is nontoxic to people and animals, environmentally safe.
Essence of the present invention is seed, stem, the leaf mixing back (ratio is not limit) with Alpinia japonica (Rhizoma Alpiniae intermediae or hair leaf Alpinia japonica), distill, concentrate, resulting solution is carried out the mensuration of aldehyde contenting amount, according to the aldehyde contenting amount that measures, determine to add how many sorbierites again, obtain the aldehyde aqueous emulsion that aldehyde contenting amount is 10-60% after the two is cooperated, be the bactericide that the present invention produces, this bactericide is milky emulsion liquid.As the solution aldehyde contenting amount after distillation concentrates after measured is 57%, and then 100 kilograms of such solution adds 50 kilograms of sorbierites can to obtain aldehyde contenting amount is 38% bactericide.
This method is comparatively easy, practical, raw material is easy to get.Bactericide Nonpoisonous, non-environmental-pollution with this method production, the corps diseases that is caused by fungi, bacterium and parasitism algae there is remarkable prevention effect, be used to prevent and treat the disease of crops such as fruit tree, vegetables, melon, cotton, medicinal material, tealeaves, oil palm, mango, lichee, fragrant firewood, efficient reaching about 80%.To promoting the growth of crop, also have certain effect.
Embodiment:
Get 100 kilograms of Alpinia japonica, after seed, stem, leaf are mixed, distill, concentrate and purify, gained solution carries out the mensuration of aldehyde contenting amount, according to the aldehyde that records, determine to add many a spot of sorbierites, the aldehyde that makes the aldehyde aqueous emulsion that obtains after the two cooperation is between 10-60% again.This aldehyde aqueous emulsion is the bactericide that indication method of the present invention makes.As the extract aldehyde contenting amount that distills after concentrating is 70%, just then 10 kilograms of such extracts add 4 kilograms sorbierite again to obtain aldehyde contenting amount be 50% bactericide.This bactericide will be determined extension rate according to aldehyde in use, is 10% as aldehyde, then dilutes 400-500 doubly; Aldehyde is 30%, then dilutes 600-1000 doubly, and aldehyde reaches 50-60%, then can dilute 2000 times.
Claims (2)
1, a kind of method of making bactericide by plant extraction liquid, after it is characterized in that the seed of Alpinia japonica, stem, leaf mixed distillation, concentrate again and purify, resulting solution is carried out the mensuration of aldehyde contenting amount, actual content according to aldehyde, determine to add many a spot of sorbierites again, obtain the milky aldehyde aqueous emulsion that aldehyde contenting amount is 10-60% after the two is cooperated.
2,, it is characterized in that said Alpinia japonica is Rhizoma Alpiniae intermediae or hair leaf Alpinia japonica according to the described method of claim 1.
