大豆孢囊线虫对大豆生长发育的影响,主要是它寄生于根的皮层中,吸收地上植株输送给根部有机营养。使大豆根系失去吸收水和无机盐所需的能力,进而使植株根部吸收能力下降,地上部分得不到足够的水和无机盐,也就不能很好地进行光合作用,不能合成有机物供根、茎、叶生长所需。从而产生恶性循环,严重影响大豆生长发育及秋后的产量。 Soybean cyst nematode on the growth and development of soybeans, mainly because it is parasitic in the cortex of the roots, the absorption of aboveground plants to the roots of organic nutrition. So that the roots of soybeans lose the ability to absorb water and inorganic salts, thereby reducing the ability of plant roots to absorb less water and inorganic salts on the ground, it can not be good for photosynthesis, organic matter can not be synthesized for root, Stems, leaf growth required. Resulting in a vicious cycle, seriously affecting the growth and development of soybean and yield after autumn.
