我省边疆少数民族历史上种庄稼多为刀耕火种,管理粗放,近年来,在农技人员指导下,加上《云南农业科技》的介绍宣传,改变了落后的传统耕作制度,采用科学的栽培技术,普遍重视了农家肥的施用,并掌握了微量元素和植物生长调节剂在各种作物上的应用方法,使水稻连年增产。1989～1990年杂交稻种植面积已达80%以上,每亩产量由400～500斤提高到800斤以上。
In history, most of the ethnic minorities in the border areas of our province grow slash and burn their crops and manage extensively. In recent years, under the guidance of agricultural technicians, the introduction and promotion of “Yunnan Agricultural Science and Technology” has changed the backward traditional farming system and adopted scientific cultivation techniques , Generally attached importance to the application of farmyard manure, and mastered the application of trace elements and plant growth regulators in a variety of crops, so that rice yield year after year. From 1989 to 1990, the acreage of hybrid rice has reached more than 80%, and the yield per acre increased from 400 to 500 kg to over 800 kg.
