摘要
为开发来源广泛、经济实惠和性能优良的马铃薯微型薯繁育基质,采用3因素5水平正交旋转组合设计,对菌渣、河沙、珍珠岩3种基质的配比进行优化。结果表明:由马铃薯微型薯产量(Y)与菌渣配比(X1)、河沙配比(X2)、珍珠岩配比(X3)间的回归方程Y=36.331 63–1.819 65X1+3.391 04X2+2.568 47X3–1.786 37X12–4.208 21X32+2.122 50X1X2+4.327 50X1X3可推断,珍珠岩配比对马铃薯产量的影响最大,其次是菌渣配比,最后是河沙配比;河沙配比与珍珠岩配比间的交互效应不显著,菌渣配比与河沙配比、菌渣配比与珍珠岩配比间的交互效应显著;通过多元回归和频率分析法分析,得到马铃薯微型薯繁育基质菌渣、河沙、珍珠岩的适宜体积比为(1.677～2.000)∶(1.157～1.452)∶(1.000～1.260)。
To develop a kind of extensive, cheap, and good quality substrate for potato micro-tubers breeding, quadratic-orthogonal-rotation-combination design was adopted to optimize the ratio of three substrates （mushroom residues, sand and perlite）. From the regression model established between yield of micro-tubers （Y） and mushroom residue （X1）, sand （X2）and perlite （X3）, which was expressed as Y=36.331 63-1.819 65X1＋3.391 04X2＋2.568 47X3- 1.786 37X1^2-4.208 21X3^2＋2.122 50X1X2＋4.327 50XlX3, it showed that the yield of potato micro-tubers decreased in the order of perlite, mushroom residues, and sand. It was also concluded from the model that there was no significant interaction between sand and perlite to the yield, while the interaction between mushroom residues and sand become obvious, the same was true for mushroom residues and perlite. The volume ratio of mushroom residue, sand and perlite was optimized as follows： （1.677-2.000）： （1.157-1.452）： （1.000-1.260） according to multiple regression and frequency analysis.
