【摘要】 在20℃恒温下,花生种子用各种浓度的硫酸锰、硫酸锌、硼酸及钼酸溶液浸种两小时,用砂培法观察其发芽及幼苗生长。结果在发芽指数、幼苗长度及干重上均超过对照的有硫酸锰两组(浓度为0.015及0.15g/L)、硼酸三组(浓度为0.005,0.05及0.25g/L)及钼酸三组(浓度为0.045,0.15及0.45g/L)。小区试验结果表明:除硼外,锰、锌、钼均有提高花生荚果产量的作用。浸种溶液浓度为0.15及0.45g/L的钼酸,分别增产21.7％及27.3％;浓度为0.15g/L的硫酸锰增产14.0％;浓度为0.015g/L的硫酸锌增产11.9—12.0％。试验所收获的花生种子经过化学分析,证明锰有促进蛋白质合成的作用,硼有促进脂肪合成的作用,钼则使种子水分含量增加,而脂肪及蛋白质均有所减少,原因未明。更多还原

【Abstract】 In order to test the effect of manganese, zinc, boron and molybdenum upon the early growth, yield and quality of peanut, a series of experiments have been made. The experiment of the germination and early growth was conducted in the laboratory. Peanut seeds of uniform size were carefully selected. Batches of seeds were washed with sterile redistilled water and then soaked for 2 hours in the test solutions or in redistilled water as control. The treated seeds were germinated in sand for 260 hours at a constant temperature of 20℃. in an incubator. After the frequency of germination was observed, the seedlings were fixed in five percent formalin for length measurement and determination of dry weight. The data of the result indicate that manganese sulphate (0.015g/L, 0.15g/L), boric acid (0.005g/L, 0.05g/L, 0.25g/L) and molybdic acid (0.045g/L, 0.15g/L, 0.45g/L) have a beneficial effect upon the germination and growth of seedlings, both in length and in the accumulation of dry matter. In the field experiment, the peanut seeds were treated with the test solutions before being sown. The results show that the yield is increased by 21.72％ and 27.3％ respectively by the treatment with 0.15g/L and 0.45g/L molybdic acid and increased also 14.0％ and 11.9—12.0％ respectively by the treatment with manganese sulphate 0.15g/L and 0.015g/L zinc sulphate. Besides, treatment with trace elements also brings about an increase either in protein or fat content of the seeds obtained from the field experiment. It was found that protein is increased by 2—2.3％ as a result of treatment with manganese sulphate and fat is increased by 5.8—6.8％ by the treatment with boric acid. The result of the present work leads to the conclusion that the peanut seeds treated with manganese sulphate and molybdic acid in adequate concentration not only have a good effect on the early growth and yield but improve the quality of the seed as well.更多还原
