科学家 Forolla 在温室中发现一熟性特别的大豆变种,可与杂草抗争,利用这种作物每年可减少75%的除草剂用量。这是由于该种大豆植株上部叶子一但产生,生长非常快,可在50天内达到最大叶面积。在这样一个足够大的作物伞下生长的杂草,因不能得到正常生长所需的光照,而 Forolla, a scientist who discovered a one-of-a-kind soybean variant in the greenhouse, could fight weeds, reducing the use of herbicides by 75% a year. This is due to the fact that the upper leaf of the soybean plant produces but grows very fast, reaching the maximum leaf area in 50 days. Weeds that grow under such a large enough crop umbrella can not get the light needed for normal growth
