摘要
为探究目前常用的不同育秧基质对机械化水稻生产的影响,以便找出具推广价值的育秧基质。以‘金早47’为试验材料,梯度试验法研究基质母剂的适宜用量,并以‘金早09’和‘甬优9号’为试验材料,比较无机基质、母剂、壮秧剂、客土(对照)4种育秧基质对机插秧苗素质和产量的影响。结果表明,母剂的适宜用量为母剂与客土1:3。基质试验结果显示,3个处理培育的秧苗叶龄、基茎宽、干物质量三项指标均比对照增高,并以无机基质条件下最高。产量方面,3个处理条件下有效穗数和产量增加,‘金早09’在无机基质条件下产量最高,比对照增加2.88%,‘甬优9号’则在母剂条件下达到最高,比对照增加8.86%。3种基质均具有壮苗增产的功能,但以无机基质和母剂的效果更佳,在生产上极具推广应用价值。
The study aimed at the influence of different seedling raising substrates on mechanized rice production, to find out the raising substrates with great extension value. First, the experiment of gradient dosages was carried out to investigate the suitable dosage of substrate mate, using Oryza sativa cv.‘Jinzao 47＇.Then the influence of four types of substrates including inorganic substrate, substrate mate, seedling-strengthening agent（SSA） and soil（CK） on mechanical transplanting seedling quality and yield were compared,using Oryza sativa cv.‘Jinzao 09＇and‘Yongyou 9＇. Results showed that, the suitable dosage of substrate mate was substrate mate：soil =1：3. Result of substrate comparison showed three indexes of seedlings raised on inorganic substrate, substrate mate and SSA were higher than CK, including leaf age, basal stem width and dry matter weight, all of which for two varieties were highest on inorganic substrate. In addition, effective panicle number and yield were also higher than CK, while the highest yields of‘Jinzao 09＇was on inorganic substrate,increasing by 2.88%, and‘Yongyou 9＇was on substrate mate, increasing by 8.86%. The three substrates were all beneficial to nurse strong seedling and improve yield, while among these inorganic substrate and substrate were with better functions, thus were with great extension values at rice production.
