油菜缺硼已在我省许多地方发现。油菜缺硼多发生在质地偏沙、有机质含量低的土壤上。近年来在我省红壤地区,油菜外观上虽无明显的缺硼症状表现,但施硼后有明显增产效果,说明存在潜在性缺硼问题。有些土壤既缺硼又缺钾,严重影响了油菜籽的产量和品质。国外许多研究者曾对多种作 Rape lack of boron has been found in many parts of our province. Rape lack of boron occurred in the texture of partial sand, low organic matter content of the soil. In recent years, red soil areas in our province, rape appearance although no obvious symptoms of boron deficiency, but after boron has obvious yield increase effect, indicating the existence of potential boron deficiency. Some of the soil is deficient in both boron and potassium, severely affecting rapeseed production and quality. Many foreign researchers have done for many kinds of work
