庆安县位于黑龙江省中部,地处松嫩平原东部边缘,小兴安岭西侧。土地绝大部分为黑钙土,PH6.5～7.5。我县种植甜菜已有三十多年的历史,但是亩产一直较低,为了探索提高甜菜单产的途径,我们于一九七九、一九八○年开展了甜菜施硼、钼肥试验。 一九七九年试验,用钼酸铵和硼砂拌种、叶喷,共进行24次试验。结果表明:甜菜用0.2%的钼酸铵溶液浸种24小时,其亩产3740斤,比对照(清水浸种)增产15.3%;用0.2%的硼砂(药用)浸种,其产量比对照高3.6%。于甜菜快速生长时期(七月十日),用0.03%的钼酸铵溶液叶喷,甜菜亩产3201.6斤,比对照(清水)增产14.2%;用0.03%的硼砂(药用)溶液叶喷,亩产3681.8斤,比对照(清水)增产31.4%。
Qing’an County is located in the central Heilongjiang Province, located on the eastern edge of the Songnen Plain, west of Xiaoxing’anling. The vast majority of land for the black earth, PH6.5 ~ 7.5. We have been cultivating beet for over 30 years, but the yield per mu has been relatively low. In order to explore ways to improve yield of sugar beet, we conducted beet boron and molybdenum fertilizer tests in 1979 and 1980. Test in 1979, with ammonium molybdate and borax dressing, leaf spray, a total of 24 tests. The results showed that the yield of beet was increased by 15.3% compared with that of the control (fresh water soaking) after it was soaked in 0.2% ammonium molybdate solution for 24 hours and soaked with 0.2% borax (medicinal), its yield was 3.6% . In the rapid growth period of sugar beet (July 10), the leaf was sprayed with 0.03% ammonium molybdate solution. The yield of beet was 3201.6 kg, an increase of 14.2% compared with that of the control (clear water); the leaf spray was sprayed with 0.03% borax , 3681.8 kg per mu, compared with the control (water) increased 31.4%.
