近日请教了一位农艺师朋友,他告诉我:除草剂之所以能杀死杂草,而不伤害农作物,是因为农作物和杂草在生理生化、时差位差、发展阶段、生长形态等几个方面存在着差异。人们根据这些特点,才研制出了除草剂。他还告诉我,使用除草剂也需因地制宜、适度适量才行,要是乱用一通,往往也会事与愿违。万一购买了假冒伪劣产品,大面积使用那就惨了。 三句话不离本行。由除草剂我想到了批评报道。 Consult an agronomist friend recently, he told me: the reason why weed killers can kill weeds, without damaging crops, crops and weeds because of physiological and biochemical, time difference, development stage, a few growth patterns There are differences in terms. Based on these characteristics, people developed the herbicide. He also told me that the use of herbicides also need to be adapted to local conditions, appropriate amount of Caixing, if used indiscriminately, often will be contrary to expectations. If you buy fake and shoddy products, large-scale use that would be miserable. Three words from the Bank. I think of the criticism from the herbicide reports.
