我县土壤速效硼含量普遍偏低。为了摸索硼肥对蚕豆生长发育的影响,从1981年开始,由县土肥站主持、七个区镇场农技站(股)参加,采取小区试验和大面积示范相结合,对蚕豆施硼肥的时间、方法、用量及其增产效果进行了试验。四年结果表明,蚕豆施硼肥,增产显著,亩产由263斤提高到313.1斤,增产19.1％。试验示范面积由500亩发展到28,700亩。现将结果综合整理如下。 The available boron content of soil in our county is generally low. In order to explore the impact of boron fertilizer on the growth and development of broad bean, from 1981, hosted by the county soil fertilizer station, seven districts farm field station (unit) to participate in, to take community trials and large-scale demonstration of the combination of broad bean boron fertilizer The time, the method, the dosage and the stimulation effect were tested. Four-year results show that broad bean application of boron fertilizer, significant yield increase from 263 pounds per mu to 313.1 kg, an increase of 19.1%. Demonstration area from the development of 500 acres to 28,700 acres. The results are summarized below.
