Abstract

The application of sorption preparations (SP) based on bentonite-humate mixtures for seed stimulating treatment upon sowing into the soddy-podzolic soil (Albic Retisols (Loamic, Aric, Cutanic, Ochric)) was studied. The correlation between seeds’ inhibition by soil and the efficiency of SP application was found. The SP treatment was not always efficient for spring wheat cultivars. For some of the cultivars, it caused inhibition of seed germination and seedlings development. The intake of essential biologically active substances (BAS) from soils to seeds was limited in these cases because of the firm fixation of these substances in SP. The brewer’s yeast autolysate (BYA) introduced to the SP mixture made it possible to fill the active centers of sorbents and to avoid the fixation of BAS from soil. The obtained preparation eliminated inhibition of seed development at the initial stage upon SP application. The efficiency of previously known individual stimulating substances sharply increased upon their combined application with SP and BYA mixture.

植物发育初期的土壤化感作用及其减轻不良影响的方法

摘要

研究了基于膨润土-腐植酸盐混合物的吸附剂（SP）在播种到多沙的土壤（Albic Retisols（Loamic，Aric，Cutanic，Ochric））中用于种子刺激处理的应用。发现了土壤对种子的抑制作用与SP施用效率之间的关系。SP处理对春小麦品种并不总是有效的。对于某些品种，它会抑制种子发芽和幼苗发育。在这些情况下，由于将这些物质牢固地固定在SP中，因此从土壤到种子的必需生物活性物质（BAS）的摄入受到限制。将啤酒酵母的酵母自溶物（BYA）引入SP混合物中，可以填充吸附剂的活性中心，并避免土壤中BAS的固定。所获得的制剂消除了SP施用初期对种子发育的抑制。与SP和BYA混合物一起使用时，先前已知的单个刺激物质的效率急剧提高。
