以往试验阐明,柑桔紫血焦病的发病区域和发病品种,以及发病树上存在着以锰为主的多种营养元素缺乏症。病果果皮样品的分析结果还表明:紫血焦病与锰的含量有着特别明显的关系。由此推测,紫血焦病可能与锰的代谢有关,因此进行了喷锰对防治紫血焦病效果的研究。 一、试材和方法 试验园位于澄江中下游两岸的脱盐土,供试树为40年生左右的构头橙砧早桔。 方法:在6～7月喷施0.3％硫酸锰溶
Past experiments clarify the incidence of purple blood purple coke disease areas and the incidence of species, as well as the incidence of the existence of manganese-based multiple nutrient deficiency. Fruit peel samples analysis results also show that: purple blood coke disease and manganese content has a particularly significant relationship. It is speculated that purple blood coke may be related to the metabolism of manganese, manganese spraying on the prevention and treatment of purple blood coke effect of the study. First, the test materials and methods Test Park is located in the middle and lower reaches of Chengjiang desalination soil, for the test tree is about 40-year-old orange anteater orange ancestor. Method: 0.3% manganese sulfate solution was sprayed from June to July
