亚麻产量的形成是不同农艺措施综合作用的结果。鉴于过去的试验结果,为尽快地摸索出万亩亚麻亩产550斤的综合农艺措施与产量的关系,在农业系统工程理论及二次正交回归旋转设计的方法指导下,进行万亩亚麻综合高产试验的研究,对多年亚麻单项研究成果与当地高产经验进行综合研究。1984～1985年在兰西县红星、兰河乡研究了播期、密度、二铵、锌肥四因素五水平与亚麻原茎产量间的综合关系。两年面积达21,912亩,平均亩产亚麻原茎555.02斤,其中1984年亩产亚麻原茎557.3斤,1985年亩产原茎552.4斤。通过对数学模型的分析,得出亩产550斤亚麻原茎不同农艺措施相互作用的综合效应,两年试验结果趋向一致。
The formation of flax yield is the result of a combination of agronomic measures. In view of past test results, in order to quickly find a mu mu yield of 550 pounds per mu of comprehensive agronomic measures and the relationship between yield, agricultural systems engineering theory and quadratic orthogonal regression rotation design under the guidance of the method, mu mu flax synthesis High-yield test research, many years of flax research results and local high-yielding comprehensive study. 1984 to 1985 in Lanxing County, Hongxing, Lanhe Township, sowing date, density, diammonium, zinc fertilizer, four factors and five levels of flax stalk yield comprehensive relationship. Two-year area of 21,912 acres, the average yield of 555.02 tons of flax per grass, of which mu yield of raw linen in 1984 557.3 kg, 552.4 kg per mu in 1985. Through the analysis of the mathematical model, the comprehensive effect of interaction of different agronomic measures on the yield of 550 kg of flax per mu was obtained. The results of two years tended to be consistent.
