当前,在防治油菜“花而不实”症方面,硼肥喷施办法已被广泛采用.三年来我们试验的结果也同样证明效果是良好的.特别在严重发生“花而不实”症的情况下,效果尤为突出.我们在1973年的一般情况下喷施,增产43%;在“花而不实”症较轻的1974年喷施,增产76%;在“花而不实”症发生严重的1975年喷施,增产竟达218%之多.在过去三年喷施硼肥的基础上,又作了更进一步的试验,将喷施改为基施,施用等量的硼肥,结果表明,基施的防病增产效果更好,更有推广使用价值.
At present, the application of boron fertilizers has been widely adopted in the prevention and treatment of rape blossoms, and the results of our experiments in the past three years also prove that the effect is good, especially in the serious case of “blossoming” In the case of the case, the effect is particularly prominent.We sprayed in the general case of 1973, an increase of 43%; In 1974, sprayed “light but not solid” mild disease, an increase of 76%; in the " In 1975, a serious spraying occurred, increasing production up to as much as 218% .Booning boron fertilizer in the past three years, based on the further tests, the spray to the base facilities, the same amount of boron fertilizer The results showed that the effect of disease prevention and yield increase of Kishi was better and the use value was promoted.
