竹菲10是中国水稻研究所和浙江省农科院选育的一个迟熟早籼品种,是温岭县早稻迟熟品种的当家种。为了进一步摸清竹菲10的丰产栽培技术,发挥其坛产潜力,提高经济效益,特进行本试验。一、试验设计和方法田间试验采用三元二次回归旋转组合设计,设置试验小区23个,其中三因子二水平全因子试验小区8个,星号点试验小区6个,零水平中心试验小区9个,小区之间筑保肥土埂,小区面积16.7平方米。试验以产量为目标函数,选择播种量(X_1),插秧本数(X_2),施肥量(X_3)作为控制变量(试验因素),因素水平编码见表1 试验田设在温岭县三星桥绿肥田,土壤类型属青紫泥,肥力水平较高。各小区以每亩10斤过
Bamboo Philippine 10 is a late maturing indica variety bred by China National Rice Research Institute and Zhejiang Academy of Agricultural Sciences, which is the original species of late maturing varieties of Wenling County. In order to further find out the high yielding cultivation techniques Zhufang 10, to play its altar potential, improve economic efficiency, especially for this experiment. First, the experimental design and methods Field experiment using three yuan quadratic regression rotary combination design, set up a pilot area of 23, of which three factor two level full factor test plot 8, asterisk test plot 6, zero-level central test plot 9 A, between the community to build fertile soil 埂, residential area of 16.7 square meters. The yield was taken as the objective function, the seeding rate (X_1), transplanting seedling number (X_2) and the amount of fertilizer application (X_3) were selected as control variables. The coding level of the factors is shown in Table 1. The experimental field is located in the green manure field of Sanxingqiao, Wenling County. Type is purple, high fertility level. Each district to 10 pounds per acre over
