【摘要】 为提高硒在豌豆幼苗中的含量,调查化学物质对豌豆幼苗生长和富硒的影响,在豌豆幼苗生长期间,喷施硝酸钾、磷酸二氢钾、蔗糖、无根豆芽素,在苗高2.5,5.0和7.0 cm时,喷施100 mg/L亚硒酸钠,结果表明,10 mmol/LKH2PO4和30 mmol/LKH2PO4处理对豌豆幼苗生长和全硒、大分子结合硒的含量提高具有较明显作用。更多还原

【Abstract】 30 mmol/L KNO3,60 mmol/L KNO3,10 mmol/L KH2PO4,30 mmol/L KH2PO4,3%sugag,0.03%rootless plant growth regulator were sprayed on the pea sprout when seedling 2.5 cm,5.0 cm and 7.0 cm high,to test its effect on the growth of the sprout and the accumulation of selenium.The result shows that 10 mmol/L KH2PO4 and 30 mmol/L KH2PO4 enhence the yield of the sprouting vegetable and make the total quantity of selenium absorbed and large moleculer-linked selenium increase markedly.更多还原
