研究了苎麻栽培密度、氮、磷、钾肥用量及收获期对苎麻不同麻龄的纤维产量、纤维支数的影响,建立了相应的数学模型。经微机模拟寻优决策出了苎麻高产优质优化栽培方案。生产示范及多点验证结果表明,优化方案的理论值与实测值拟合性好,一龄麻比对照增产18.88％,纤维支数增加119m/g;成龄麻比对照增产28.94％,纤维支数增加110m/g。
The effects of planting density, nitrogen, phosphorus and potassium fertilizer amount and harvesting period on the fiber yield and fiber count of ramie were studied, and the corresponding mathematical model was established. Through computer simulation to optimize the decision out of high yield and high quality ramie cultivation plan. Production demonstration and multi-point verification results show that the theoretical value of the optimized scheme has good fitting with the measured value. The yield of the first instar hemp is 18.88% higher than that of the control and the number of fiber is increased by 119m / g. The mature yield is 28.94% more than that of the control, Increase the number of 110m / g.
