随着各种肥料在油菜上施用量的增多,特别是氮素,磷素肥料施用量的增加,促进了油菜产量的逐年增长,从而引起甘蓝型油莱对微量元素硼的缺乏,导致油菜“花而不实”的生理性病害加重,影响油菜产量的进一步提高。三十烷醇有刺激作物生长的作用,微量元素硼能防治油莱“花而不实”。据外地经验,三十烷醇和硼肥对油菜都有一定增产效果。笔者设想二者混合喷施对油菜的增产作用将会更大。为此,我站于1984年10月至1985年5月进行硼肥与三十烷醇混合喷施对
With the increase of application amount of various fertilizers on rapeseed, especially the increase of nitrogen and phosphorus fertilizers, the annual increase of rapeseed production has been promoted, resulting in the lack of trace element boron in Brassica oleracea resulting in the “ Flower but not real ”aggravating physiological diseases, affecting the further improvement of rapeseed production. Triacontanol has the effect of stimulating crop growth, and boron can prevent and cure oil-labled flowers. According to field experience, triacontanol and boron fertilizers have a certain yield increase effect. The author envisages that the combination of the two will increase the yield of rapeseed more. To this end, I stood in October 1984 to May 1985 for boron and triacontanol mixed spray pairs
