通过对试验资料综合分析,求得一个新的适合于中、高产麦田推算合理基本苗的经验公式: l(?)=2.8121lgA-0.002195∑T-0.428d-2.8121lgp-2.2283 进而提出了“以光定穗”(或以产定穗)“以穗定苗”、“以苗定种”三个技术环节的系列化公式。使之有可能通过事先计算来确定合理的基本苗。
Based on the comprehensive analysis of the experimental data, a new empirical formula suitable for the calculation of reasonable basic seedlings in medium and high yielding wheat fields was obtained: l (?) = 2.8121lgA-0.002195ΣT-0.428d-2.8121lgp-2.2283, Guangshui Sui “(or to produce spike)” Sui Sui Miao “,” Miao Dingzhu "three series of technical formulas of the formula. It is possible to determine a reasonable base seed by prior calculation.
