湖南省土肥学会于1981年6月2日到5日在沅江县主持召开了微量元素肥料学术讨论会,参加这次会议的有省农学会、省农业厅、省土肥所及地、县有关单位的代表共24人。会议交流了近几年开展微肥试验的示范、推广应用方面的经验,参观了沅江县农科研、沅江县星火公社推广应用微肥的现场,讨论了微肥的施用条件和技术,提出了进一步开展微肥试验示范的建议:1.要重视已有科研成果的应用。1973年以来的试验证明,钼肥对豆科绿肥作物、大豆和花生;锌肥在湖区和紫潮泥、紫泥田等土壤上对水稻,均有明显的肥,增产10—20％。硼肥在湖南大部分缺硼土壤上,可防治油菜花而不实,增产13％。另外,在武冈、隆回和石门等县发现柑桔、棉花施锌肥后,可减少落果落蕾和提高产量有良好作用,在链源地区施用锰肥也有一定增产效果。为此建议各有关部门要积极而慎重地组织推广应用;2.必须掌握微肥的施用条件
Hunan Soil and Fertilizer Association in June 2, 1981 to 5 held in Yuanjiang County hosted a seminar on trace element fertilizers, to participate in the meeting of the Provincial Association of Agriculture, the Provincial Department of Agriculture, Provincial Soil and Fertilizer Institute and the relevant units A total of 24 representatives. The meeting exchanged experiences of demonstration, popularization and application of trace fertilizer experiment in recent years, visited the field of agricultural research in Yuanjiang County, promoted the application of micro-fertilizer in Yuanjiang County Spark Commune, discussed the application conditions and techniques of the micro-fertilizer and proposed further To carry out micro-fertilizer test demonstration recommendations: 1. We must pay attention to the application of existing scientific research. Experiments since 1973 have proved that molybdenum fertilizes on leguminous green manures, soybean and peanut; zinc fertilizer shows obvious fertilizer on paddy soils in Lake District, purple tide mud and purple clay soil, yielding 10-20% increase. Boron fertilizer in most of the boron-deficient soil in Hunan, can prevent rape foul and false, an increase of 13%. In addition, citrus fruits were found in counties such as Wugang, Longhui and Shimen. After applying zinc fertilizer to cotton, they could reduce the effects of falling fruit buds and increasing yield, and the application of manganese fertilizers in the chain source areas also had some stimulation effects. To this end suggest that all departments concerned should actively and prudently organize the promotion and application; 2 must master the application conditions of fertilizer
