Description
Technical field
The present invention relates to technical field of pesticide, particularly relate to a kind of weed killer herbicide being exclusively used in the bighead atractylodes rhizome and mix thing and weeding micro-dose.
Background technology
The bighead atractylodes rhizome is the rhizome of the composite family [WTBX plant bighead atractylodes rhizome, has strengthening the spleen and replenishing qi, eliminating dampness Li Shui, the clinical common medicine that hidroschesis is antiabortive.In bighead atractylodes rhizome planting process, be often subject to the harm of weeds in field.Weeds and the bighead atractylodes rhizome are striven fertilizer and are striven water, but also the insect pest that easily spreads disease, affect the seed output and quality of the bighead atractylodes rhizome.General weeds can adopt in conjunction with field management processes such as applying fertilizer, pour water and manually pull out or artificial weeding, but artificial weeding is time-consuming, and cost is very high.
Along with the fast development of science and technology, chemical weed control as a modernization practical technique, plays huge in weed control. effect.Although the development time of Application of Herbicides is not long, development speed is very fast.Along with the development of Chinese agricultural modernization and the progressively transfer of agricultural workforce, cultivation tillage method trends towards scale and intensive, significantly increases the demand of agricultural chemicals.Wherein, weed killer herbicide growth rate in recent years, far above insecticide and bactericide development level, accounts for 1/3 of agricultural chemicals output proportion.
At present, weed killer herbicide of a great variety, is divided into cauline leaf inorganic agent and closed soil treatment agent according to using method, is divided into selectivity and natural disposition two class of going out according to its mode of action; Contact killing type weed killer herbicide and conductive pad weed killer herbicide is divided into according to the conductivity in plant corpus; Sulfonephthalein amine weed killer herbicide and apple acid herbicides etc. is divided into according to chemical composition.But the group of agriculture old weeds composition is diversified, and also change along with the kind of the different growing weeds of crop.Although in order to farmland chemical weed control need develop a large amount of weed killer herbicide kind and select on producing.But, often kind of weed killer herbicide has the weeds kind of specifically preventing and treating, lack very much now the weed killer herbicide kind can preventing and treating crop all weeds in the time of infertility selectively, simultaneously, the weed killer herbicide kind that Long-Time Service is single, can cause weeds to produce resistance or cause the rapid replacement of the change of weeds kind, weed population, substantially increasing the difficulty of farmland chemical weed control, while exploitation novel herbicide, the used in combination of two or more weed killer herbicide kind is also arisen at the historic moment.
The mixed of weed killer herbicide has many advantages: 1, can expand herbicide spectrum; 2, weed killer herbicide remaining in crop and soil is reduced; 3, avoid poisoning, improve the safety to crop; 4, reduce costs, increase economic efficiency and save labour; 5, the service life of weed killer herbicide is extended; 6, effectively Herbicide-resistant weeds is prevented and treated; 7, herbicide mixture can reduce the kind consumption of lasting period length, thus can be reduced in soil residual, prevent the poisoning to late stubble sensitive crop, reduce the pollution to environment.
Chinese medicine is the cultural heritage of China's preciousness, is Chinese nation's disease preventing and treating, rehabilitation, a magic weapon that produces offspring.Countries in the world are to the demand expanding day of natural drug in recent years, especially particularly pay close attention to green medicine.Now, the annual Chinese medicine volume of trade in the world oneself reach 40,000,000,000 dollars, and every year with 10% speed increment, current China Chinese medicine export amount about 600,000,000 dollars, only accounts for the 30%-5% in cosmopolitian plant medicinal material market, and the status of this and Chinese medicine big country of China is extremely unbecoming.The residual quantity of the harmful substances such as the uncertain and agricultural chemicals heavy metal of active ingredients from traditional Chinese medicinal exceeds standard, and is the two large obstacles that Chinese medicine ranks among the world.The Chinese herbal medicine of China's export is repeatedly because the reasons such as residue of pesticide exceed standard are checked and detained on the state markets such as America and Europe, and pesticide residual contamination has become the obstacle that traditional Chinese medicine goes to the world, becomes the major issue that in current Producing medicinal herbs, letter is to be solved.
Different weed killer herbicide kind is different in controlling object, action characteristic, so should according to the kind of crop, weeds in field occurs, the specificity of distribution and group, selects suitable weed killer herbicide kind.In addition, the lasting effect of the remaining influence of weed killer herbicide in soil to weed killer herbicide and the safety to environment.From the viewpoint of management of weeds, weed killer herbicide should have certain residual life, and residual life is too short, and herbicidal effect is bad, but residual life is oversize, can cause again under recommend the poisoning of crop.But consider from environmental, the residual life of weed killer herbicide is more short better, and weed killer herbicide is too stable, not easily degrades, residual quantity is large in the environment, can cause environmental pollution.
