摘要

通过盆栽试验研究氨基酸螯合微肥（AA-Met）对早作水稻苗期生长的影响。结果表明：AA-Met能显著提高早作水稻的株高、根长及生物量。喷施后72h内每24h用SPAD-502测定叶绿素相对含量，发现旱作水稻对螯合态微肥的吸收同化速率显著大于无机微肥，但AA—Met与EDTA—Met（EDTA螫合微肥）间差异不显著。等量施用微量元素下，AA—Met和EDTA—Met处理的生物量、叶绿素和生长素含量均显著高于无机微肥处理，而两螯合态微肥处理间差异不显著。可溶性蛋白含量3种微肥处理间差异显著，表现为AA-Met处理〉ED—TA—Met处理〉无机微肥处理（P〈0．05），表明AA—Met可完全替代EDTA—Met。分别喷施稀释100（AA—Met1）和250（AA—Met2）倍AA—Met的溶液时，作物生物量、叶绿素、生长素及可溶性蛋白含量两处理间差异不显著，但显著高于喷施稀释500（AA—Met）倍的AA—Met溶液的处理。

Abstract

A pot experiment was conducted to evaluate the effect of chelated micronutrient fertilizers(amino acid and EDTA chelated) and inorganic micronutrient fertilizer on growth of rice cultivated in aerobic soil.Results regarding biomass

biological properties

chlorophyll and IAA contents showed non-significant differences between amino acid chelated micronutrient fertilizer(AA-Met) and EDTA chelated micronutrient fertilizers(EDTA-Met)

whereas these differences were highly significant when AA-Met and inorganic micronutrient fertilizer treatments were practiced.The protein contents of different type micronutrient fertilizer treatments were significant difference and were in the following order: AA-Met>EDTA-Met>inorganic micronutrient fertilizer.The biomass

chlorophyll and IAA contents of different content of AA-Met showed non-significant differences when AA-Met1 and AA-Met2 were applied whereas these differences were highly significant when AA-Met2 and AA-Met3 were practiced.AA-Met will take the place of EDTA chelated fertilizer and can be widely broadcasted because of its low dosage

low cost and high efficiency.
