- Title:
- Study on Mathematical Model of Comprehensive Technique for High Yield of Millet Under the Nonirrigaion Condition in the Northwestern of Shanxi
- 摘要:
- 本文对晋西北旱作条件下影响糜子产量的主要因素播期（X1）、密度（X2）、氮肥（X3）、磷肥（X4）、有机肥（X5）进行了综合研究。通过对田间试验数据的计算机运算，建立了五因素与产量的数学模型，解析了各因素及其相互效应对产量的影响，提出了在干旱条件下糜子高产综合农艺技术措施。
- Abstract:
- In 1988, the parameter tests were performed in field to establish a mathematic model under the no-irrigation condition.The contribution order of testing factors to millet yield is sowing dare >nitrogen fertilizer >organic fertilizer >phosphorous fertilizer >density.Searching for the optimization of the mofei with the computer, we assume that step is one, five factors and fire levels a composed of 3125 designs yield in 75 designs reaches mare than 225kg/mu.By frequency nalysis, the best agronomic measures can be marked out and are listed below, the plant density is 20000-25000plants/mu, sowing date is 10th-20th of June, phosphate fertilizer is 8-10kg/ma, nitrogen fertilizer 5-3kg/mu, organic fertilizer 2700-3500kg/mu.
