为全面了解和掌握油菜施硼的增产效果和技术,我们从1978年起,在全省主要土壤上安排了油菜施硼试验。现将3年的试验情况简报于后: 试验设计分两方面:(一)肥效对比试验。设对照(不施硼)、施硼两处理。施硼用0.1—0.2％的硼砂或硼酸液于油菜蕾苔期,初花期喷施,或用沾根或亩用1—2斤硼肥作底肥。(二)经济施用硼肥技术试验。包括不同用法(拌种、底肥、沾根、喷叶)、用量和用期。小区面积0.03亩左右,重复3—4次。
In order to comprehensively understand and master the yield-increasing effect and technology of rape bourgeon, we have arranged the rape boron application test on the main soil of the province since 1978. Now 3 years after the briefing on the trial: experimental design in two aspects: (a) fertilizer efficiency comparison test. Set control (no boron), boron treatment two. Boron application with 0.1-0.2% borax or boric acid solution in the rape bud period, the first flowering spray, or with a dip root or mu with 1-2 kg of boron as base fertilizer. (B) economic application of boron fertilizer technology test. Including different usage (seed dressing, base fertilizer, dip roots, spray leaves), dosage and duration. Residential area of about 0.03 acres, 3-4 times repeated.
