Abstract

Sorption-stimulating preparation for pre-sowing seed treatment, containing calcium bentonite, potassium humate, brewer’s yeast autolysate, gibberellin and polyethylene glycol has been created. It stimulates efficiently plant development from spring wheat seeds at early stages on different soils. It has been shown that high water hardness has no negative impact on the effect of stimulant. The stimulant solution should be prepared 4–6 hours prior to its application and can be stored for more than a week without losing its stimulating properties. Seeds treated by the stimulant solution can be stored more than two months without losing the results of treatment; the pre-sowing seed treatment with the stimulant solution in combination with biological and chemical fungicides does not decrease the stimulant efficiency. It has been also found that drying the soil samples to air-dry condition increases markedly the soil allelotoxicity and this phenomenon may be related to the structural transition of soil gels in the matrix, and greater availability of allelotoxins for plants. These substances are fixed on hydrophobic ingredients of particles that form the soil gels.

早期土壤对土壤的异化毒性和促进吸附的制剂的创造，以加速春小麦种子的植物发育

摘要

已开发出一种用于种子前播种处理的刺激吸附的制剂，其中包含膨润土钙，腐植酸钾，啤酒酵母自溶物，赤霉素和聚乙二醇。它可以在不同土壤上有效地刺激春季小麦种子在早期阶段的植物发育。已经显示出高的水硬度对刺激剂的作用没有负面影响。刺激剂溶液应在使用前4–6个小时制备，并且可以保存一周以上，而不会失去刺激性。经刺激性溶液处理过的种子可以保存两个月以上，而不会丢失处理结果。用刺激剂溶液结合生物和化学杀真菌剂对播种前种子的处理不会降低刺激剂的效率。还已经发现，将土壤样品干燥至风干条件会显着增加土壤的化感作用，这种现象可能与基质中土壤凝胶的结构转变有关，并且植物的化感毒素的利用率更高。这些物质固定在形成土壤凝胶的颗粒的疏水成分上。
