中文摘要:
      为研究微肥对粳稻品种‘辽粳401’秧苗及移栽后生长的影响,试验以含有Si (40%)、Mg和Ca(8%)的赛众土壤调理剂为微肥,分别以秧苗期育苗基质和移栽前基肥形式配施,研究了秧苗期和移栽后的秧苗素质、根系特征、茎蘖动态、干物质积累规律,结果表明:微肥显著提高秧苗茎基宽、SPAD值,保障移栽时期叶龄、株高,增加移栽后返青情况、分蘖能力、地上部分、地下部分干物质重,改善移栽后根系特征;秧苗期微肥施用量较小、经济成本低,为30 g/盘最佳;尽管移栽后在450 kg/hm2微肥施用量水平最高,但较300 kg/hm2微肥施用量水平增长不大;考虑到经济成本,秧苗为30 g/盘在300 kg/hm2施肥水平效果最佳。
英文摘要:
      In order to study the effects of micro-fertilizer of japonica rice cultivars liaojing401 seedlings and transplanting, use the SaiZhong soil conditioner contents of Si(40%), Mg and Ca(8%) as micro-fertilizer, respectively in seedling stage nursery substrates and basal form with before transplanting, seedling stage was studied and after transplanting seedling quality, root system characteristics, stem tillers dynamics, accumulation of dry matter, the results show that: the micro-fertilizer significantly improved the seedlings stem base width, SPAD value, leaf age in transplanting period, plant height, increase green after transplanting, tillering ability, overground part and underground part of dry matter weight, improve root characteristics after transplanting; The micro-fertilizer application of seedling stage is small and the economic cost is low, which is the best for 30g/disk. Although the level of 450kg/hm2 micro-fertilizer was the highest after transplanting, the level of the 300kg/hm2 micro-fertilizer was not increased heavily. Considering the economic cost, the rice seedlings 30g/disk in 300kg/hm2 fertilization are the best.
