The basic characters of the varieties that the yield added significantly under Cr treatment were as follows: seed setting percentage increased significantly, panicle number pot spike and sink potential increased slightly, spikelet number per panicle and 1000-grain weight decreased slightly;
从产量构成因素来看,对土壤铬处理表现为显著增产类型品种的基本特征为结实率显著提高,穗数和库容量略有提高,每穗颖花数和千粒重略有下降;
among the yield components, decreases in number of panicles per pot and seed setting rate were two main reasons for the yield reduction.
在产量构成因子中,每盆穗数和结实率是影响产量的两个主要因子。
