近年来,我州试验推广磷矿粉的数量逐年增加,施用磷矿粉的面积和作物品种也逐渐扩大,对其肥效也逐步作出充分的肯定。根据使用地区反映:磷矿粉肥只要施用得当,对水稻、玉米、花生等作物都有良好的增产效果。弥勒县虹溪公社西门三队,为使水稻高产更高产,找到了增施磷矿粉肥的有效途径。在土质相同的一块田里,分为面积相同的二块,一块栽白水秧,另一块增施磷矿粉300斤/亩作水皮肥,考察水稻植株经济性状,穗长、每穗粒数、结实率、千粒重皆增加,结果每亩增产252.2斤,平均每斤磷矿粉增产稻谷0.84斤。弥勒县西一公社三家生产队在酸性红壤旱地上作玉米施磷矿粉肥试验,在施足农家肥料和追足氮素肥料的基础上,每亩玉米地增施磷矿粉120—200斤,
In recent years, the quantity of phosphate rock promoted by our state has been increased year by year. The area and varieties of rock used for the application of rock phosphate have also been gradually expanded. Their fertilizer efficiency has also been fully affirmed. According to the use of the area reflects: phosphate fertilizer as long as properly applied to rice, corn, peanuts and other crops have a good yield. In order to increase the yield and yield of rice, we found an effective way to increase phosphate fertilizer. In the same soil in the same field, divided into two areas of the same size, a planted white water seedlings, and the other an increase of phosphate rock powder 300 kg / mu for water skin fat, inspected rice plant economic traits, spike length, grains per spike , Seed setting rate and 1000-grain weight all increased, resulting in an increase of 252.2 kg per mu and 0.84 kg of rice per kilogram of phosphate rock. Maitreya County West commune three production teams in the acid red soil dryland for phosphate fertilizer application of maize phosphate fertilizer test, full application of manure and catch-up nitrogen fertilizer on the basis of per acre maize by adding phosphate rock 120-200 kg ,
