Straw into Field is the research focus of the current agricultural production. In this study, japonica rice lines 2645, Straw into Field on rice yield and quality formation and soil characteristics. The main results are as follows: 1. Straw into Field on rice yield and quality compared with the full chemical fertilizer (CK2), wheat straw half the amount of field processing (A) and the full amount of field processing (B) into a spike, although reduced, but the number of grains per panicle, seed setting rate, grain weight, and the final yield to improve the nutritional quality of rice has increased, poor cooking quality, processing quality and appearance quality no significant change; compared with the application of organic fertilizer products processing (CK1), B treatment production can improve 3.5% processing A 1.9% reduction in overall quality of rice water is not as good as CK1 Straw into Field built on Rice before heading organic fertilizer to field processing rice tiller number, LAI, dry matter accumulation and total nitrogen content of CK2 were decreased, where A, B treatment than CK1 more obvious; heading to maturity, organic fertilizer field processing to improve over the CK2 rice tiller spike rate, grain-leaf ratio and sugar spend more than the increase in grain filling stage roots bleeding rate than enhanced, slow leaf senescence, nitrogen use efficiency increased, the size of the relationship of the physiological indicators are B GT; CK1 gt; A Straw field affect the of paddy soil physical and chemical nature of half the amount of straw Tian decomposing peak in transplanting after 17 days, the full amount of straw to field after transplanting 24d, during this period the soil pH and Eh CK1 and CK2 compared to the control are reduced; field of organic fertilizer, soil nitrogen content decreased before heading over CK2, after heading increased, phosphorus, potassium and organic matter content in the whole growth period has increased, B deal with the most obvious, no significant difference between the A processing and CK1; the DGGE analysis paddy soil microbial diversity found in the field of organic fertilizer type and quantity of soil bacteria than CK2 significant increase, organic fertilizer to field treatments compared in the critical stage of productive tillers A processing and higher of CK1 bacterial diversity, jointing to heading difference is not obvious, and mature B treatment, changes in soil nutrient content and soil bacterial diversity richness. Straw field under Nitrogen Application on rice yield and quality of wheat straw to field processing field to deal with higher yield than half the amount of field processing, but the addition to the nutritional quality of the quality indicators were lower trend ; half field of Nitrogen Application on Yield obvious impact, but the impact on the quality Basal Fertilizer to 7: panicle 3 deal with higher yield; full field of Nitrogen Application on Yield and Quality obvious impact on the base Tillering 8: panicle processing higher yield, better quality; mainly due to production and improve the quality of LAI after heading dry matter accumulation, the Root Exudate rate, SPAD readings, NR activity, nitrogen uptake and nitrogen fertilizer use efficiency.
