摘要
对茄果类蔬菜秧苗各种数量性状及其衍生的项目与前期产量进行分析表明,用y=a+bLnG回归方程拟合茄果类蔬菜前期产量y与秧苗的日均绝对生长量G(G=苗干重/育苗天数)较适宜。由于苗干重的80%左右是由茎叶干重组成的,因此也可用茎叶干重/育苗天数代替苗干重/育苗天数做G值。当LnG用x表达时,y=a+bLnG变成线性方程y=a+bx 。在衡量茄果类蔬菜秧苗质量时,可用LnG做壮苗指标。
Through the analyses drawn from the meaterials investigated on the relationships between the properties of 20 kinds of aubergine and fruit vegetable seedbng in various numbers, the derivative items and their output at earlier stage when the seedling were trasplanted.We can draw such an equation:y = a +bLnG. In the equation, y refers to the output of transplantable vegetable at earlier stage while G refers to the avera-gely daily absolate growing ( G refers to the proportion of seedling's weight to the numbers of days of seedling) . Since nearly 80% of the proportion of seedling weight consists of the proportion of the stem-leaf's weight, the proportion of the stem-leaf's weight to the numbers of days of seedling can be considered as G replacing the proportion of seedling weight to the numbers of days of seedling. When LnG is expressed with x,the equation y = a + bLnG will change into lineal equation y = a + bx.In measure of the qualities of aubergine and fruit vegetable seedling, LnG stands for the index of fine seedling.
