1983年我站按照省农牧渔业厅土肥处布置,在早大豆上应用江西大学化工系试制的硼、氮复肥进行肥效鉴定试验,取得较好增产效果,现将试验小结如下:一、试验情况:供试春大豆品种为矮脚早,试验地点设县苗圃大队,试验地面积0.7亩,系头年冬季新开垦的红壤缓坡荒地,未种过任何作物,土壤肥力极低。播种前经两犁多耙,精细整地。于3月底播种,株行距0.8×1尺,每穴点籽5～6粒,亩播量15斤。播种后用50斤钙镁磷肥拌猪粪、土灰2大担
In 1983 I station in accordance with the Ministry of Agriculture, Farming and Fisheries Office Department of soil and fertilizer placement, soybean early application of Jiangxi University Department of Chemical Engineering trial production of boron, nitrogen fertilizer fertilizer efficiency test, and achieved better yield, the test summary is as follows: First, the test Situation: Spring soybean varieties tested were bantam. The experimental site was set up as a county nursery brigade with a test area of 0.7 mu. It was the first time in winter that the newly reclaimed red soil slopes and wastelands were not planted and the soil fertility was extremely low. Before sowing by two plow more rake, fine preparation. Sowed at the end of March, the line spacing 0.8 × 1 feet, each point of seed 5 to 6, acres sowing 15 kg. After sowing with 50 kg of calcium magnesium phosphate fertilizer pig manure, soil ash 2 big burden
