Abstract

This paper presents the study results on the effect that presowing seed treatment and spraying nitrogen-fixing, phosphate-, and potassium-solubilizing bacteria on the seedlings of the Primorskaya 39 spring soft wheat (Triticum aestivum L.) cultivar have on the structural elements of productivity, yield, and the number of soil microorganisms. It was found that the total number of bacteria increases in the waxy ripeness stage when using both presowing treatment of seeds and spraying the microorganism strains on the seedlings. The maximum number of bacteria in the soil was detected in the variants when using strains of nitrogen-fixing and potassium-solubilizing microorganisms in presowing treatment (1.9 × 10⁷ CFU/g of soil) and phosphate- and potassium-solubilizing microorganisms when spraying the seedlings (2.0 × 10⁷ CFU/g of soil). The variant N1 + K2 + P6 after presowing treatment with nitrogen-fixing, potassium-, and phosphate-solubilizing microorganisms in the waxy ripeness stage showed the highest content of mobile phosphorus (92 mg/kg). High yield (4.3 t/ha) was shown by the variant N1 + P19 after presowing seed treatment with nitrogen-fixing and phosphate-solubilizing strains.

利用微生物菌株提高春小麦的产量

摘要

本文介绍了Primorskaya 39春季软小麦（Triticum aestivum L.）品种播种前种子处理以及固氮，磷酸盐和钾增溶细菌喷施对玉米结构元素的影响的研究结果。生产力，产量和土壤微生物的数量。发现在同时进行种子的预播处理和将微生物菌株喷洒在幼苗上时，在蜡质成熟阶段细菌总数增加。当在预播处理中使用固氮和增钾微生物菌株时，在这些变体中检测到土壤中的最大细菌数量（1.9×10 ⁷CFU / g土壤）和喷洒幼苗时可溶解磷酸盐和钾的微生物（2.0×10 ⁷ CFU / g土壤）。N1 + K2 + P6变种N1 + K2 + P6在蜡质成熟阶段用固氮，可溶解钾和磷酸盐的微生物进行预播处理后，可移动磷的含量最高（92 mg / kg）。在用固氮和可溶解磷酸盐的菌株预播种子后，变体N1 + P19表现出高产（4.3吨/公顷）。
