Abstract:

【Objective】 This research aims to study the effects of 'Jun Lin Tian Xia' microbial inoculant on cotton growth and development, yield and quality traits and soil physico-chemical properties. 【Methods】 The field demonstration method was adopted: 133.33 hm2 of microbial agent demonstration and 133.33 hm2 of control (7th company, 149 th regiment: 53.33 hm2, 11 th company, 134 th regiment: 40 hm2, 13 th company, 141th regiment: 40 hm2). The agronomic traits were investigated at seedling stage, bud stage and flowering and boll stage, and the yield and quality traits were measured at boll stage. 【Results】 Cotton boll opening could be 2 d earlier than the control. The number of bolls per plant increased by 0.11-0.3, the number of bolls harvested per mu increased by 12,090-18,708, and the single boll weight increased by 0.03-0.3 g ; the yield of seed cotton was increased by 76.0-100.46 kg/667m2 per mu compared with the control, and the yield of seed cotton was increased by 47.66-66 kg/667m2. The lint percentage increased by 0.57-1.14 percentage points, the breaking strength was 0.4-0.8 percentage points, and the Micronaire value decreased by 0.2. At the same time, the use of microbial agents could reduce and improve soil structure, activate soil phosphorus, and increase soil available phosphorus content. 【Conclusion】 The application of microbial inoculants can promote the growth and development of cotton, increase yield and improve quality. At the same time, the use of microbial inoculants can reduce and improve soil structure, activate soil phosphorus and increase soil available phosphorus content.

摘要:

【目的】研究施用“菌临天下”微生物菌剂对棉花生长发育、产量品质性状及土壤理化性质的影响。【方法】大田示范方法,菌剂示范133.33 hm2(2 000亩)、对照133.33 hm2(2 000亩),均为149团7连 53.33 hm2(800亩)、134团11连40 hm2(600亩)、141团13连40 hm2(600亩)。苗期、蕾期、花铃期对农艺性状调查,絮期对产量及品质性状测定。【结果】棉花吐絮比对照可以提前2 d;单株铃数增加0.11~0.3个、收获铃数增加12 090~18 708个/667m2、单铃重增加0.03~0.3 g;测产籽棉产量微生物菌剂处理较对照增产76.0~100.46 kg/667m2,机采产量增产籽棉47.66~66 kg/667m2;衣分提高0.57~1.14个百分点、断裂比强度0.4~0.8个百分点、马克隆值降低0.2。同时使用微生物菌剂可以降低、改善土壤结构,活化土壤磷素、提高土壤有效磷含量。【结论】施用“菌临天下”微生物菌剂可以促进棉花生长发育,增加产量,提高品质,同时使用微生物菌剂可以降低、改善土壤结构,活化土壤磷素、提高土壤有效磷含量。
