硼是植物生活所必需的微量元素。大量的试验证明,硼对许多作物都有明显的增产作用。但在谷子方面还很少报导。如果硼对谷子开花结实也具有良好的作用,则可为减少秕谷提高产量找出一个简便的措施。为此,我们在1964年和1980年以叶面喷洒 Boron is a trace element necessary for plant life. Numerous experiments have shown that boron has a significant yield-increasing effect on many crops. But few reports on millet. If boron also has a good effect on the flowering and fruiting of the millet, then a simple and convenient measure can be found to reduce the yield of the millet. For this purpose, we sprayed leaves in 1964 and 1980
