[Objective] The aim was to investigate the effects of fertilizer type on di- rect-seeded rapeseed and to explore effective fertilizing. [Method] Four treatments including different types of fertilizers were set in the test. Growth, photosynthesis and chlorophyll fluorescence parameters at flowering stage such as plant height, stem diameter, shoot and root dry matter, net photosynthesis, light energy conversion effi- ciency (Fv/Fm) and SPAD value, were investigated. The effects of fertilizer treat-ments on the yield of rapeseed were evaluated as well. [Result] Both multi-functional fertilizer and controlled release fertilizer could improve plant height, stem diameter, shoot dry matter, SPAD value, net photosynthesis, non-photochemical quenching (NPQ), etc., which helped increase yield and stress resistance. [Conclusion] Both multi-functional fertilizer and controlled release fertilizer could improve yield significantly while multi-functional fertilizer (MFF) was better than controlled release fertilizer (CRF). 展开更多

There is limited information about the influence of slow or controlled release fertilizer(S/CRF) on rice yield and quality. In this study, japonica rice cultivar Nanjing 9108 was used to study the effects of three different S/CRFs(polymer-coated urea(PCU), sulfur-coated urea(SCU), and urea formaldehyde(UF)) and two fertilization modes(both S/CRF and common urea(CU) as basal fertilizer, S/CRF as basal and CU as tillering fertilizer) on rice yield and quality. CU only was applied separately as control(CK). Results showed that, rice grain yield, chalky kernel rate, chalky area, overall chalkiness, and the content of gliadin, glutenin, and protein, all showed the trends of UF〉PCU〉SCU within the same fertilization mode, and showed the trends of S/CRF as basal and CU as tillering fertilizer〉both S/CRF and CU as basal fertilizer within the same type of S/CRF. In contrast, the contents of amylose, amylopectin, and starch, as well as taste value, and peak and hot viscosity showed trends of SCU〉PCU〉UF, and the trends of both S/CRF and CU as basal fertilizer〉S/CRF as basal and CU as tillering fertilizer. Among S/CRF treatments and fertilization modes, taste values of cooked rice were positively correlated with amylose, amylopectin, and starch contents, as well as gel consistency, peak viscosity, hot viscosity, and cool viscosity, while negatively correlated with globulin, gliadin, glutenin, and protein contents. The types of S/CRF and fertilization modes are important for improving rice yield and quality. Compared to CK, higher yield and similar quality of rice was achieved with UF as basal and CU as tillering fertilizer, and similar yield with improved appearance and eating and cooking quality of rice was achieved with either both UF and CU as basal fertilizer, or PCU as basal and CU as tillering fertilizer. 展开更多

This experiment explored the effects of single application of seven types of slow-and controlled-release fertilizers on rice yield and various population characteristics.Based on a study of the nitrogen(N)release characteristics of these fertilizers,pot experiments were conducted in 2018 and 2019 with split fertilization(CK,urea applied split equally at basal and panicle initiation stages,respectively)as control,which assessed the effects on SPAD value,yield and yield components,dynamic changes of rice tillers and dry matter accumulation.The results showed that the N release characteristics of different types of slow-and controlled-release fertilizers were significantly different.Polymer-coated urea(PCU)showed a controlledrelease mode and provided sustained release throughout the whole growth stages.Sulfur-coated urea(SCU)exhibited a slow-release mode,providing insufficient release at the middle and late stages.Urease inhibitor urea(AHA)and ureaformaldehyde(UF)yielded a rapid-release mode,with an explosive N release at the early stage and no release at the middle and late stages.These results showed that PCU delayed the peak seedling stage.Compared with CK,dry matter accumulation and SPAD showed no significant differences,and due to the continuous release of N throughout the growth stages,rice yield,spikelets per panicle,seed setting rate,and 1000-grain weight were all increased.Owing to the lack of N supply at the late stage and the low number of spikelets,SCU led to a reduction of rice yield,which is nevertheless not statistically significant.AHA and UF were susceptible to environmental factors and had varying effects on rice yield.The results of this experiment indicated that given a fixed amount of N applied in a pot,the stronger the N supply capacity and the longer the effective duration time of the fertilizer,the higher the dry matter accumulation at the late growth stage,and the higher the rice yield. 展开更多

Taking a three-year fertilization trial in mine reclamation soil from Shanxi Province, China as an example, the effects of different fertilization treatments on soil carbon storage and carbon fixation by corn were studied in this paper. Four treatments were designed in the experiment, including fertilizer ( F), organic manure ( M), half organic manure plus half fertilizer ( FM) and control (CK). The results showed that fertilization had certain roles in increasing organic carbon storage of mine reclamation soil, and the application of single or combined organic and inorganic fertilizers had the most remarkable influence. Meanwhile, the treatment of single or combined organic and inorganic fertilizers could improve the carbon fixation capacity of corn prominently, and increased soil organic matter input. Thus, the application of organic manure or combined organic and inorganic fertilizer has great contribution to enhancing soil carbon sink and sustainable development of agriculture. However, the combined application of organic and inorganic fertilizer is the best choice for agricultural field based on economic consideration. 展开更多

In this study, the spatial and temporal distribution characteristics of dis- solved organic carbon (DOC) in water-logged paddy soil in Yanbian were investigat- ed under conditions of different fertilization types (single application of chemical fer- tilizer, mixed application and chemical and organic fertilizers and single application of organic fertilizer) and cultivation years (80 years and 120 years). The results showed that the spatial and temporal distribution of DOC in water-logged paddy soil changed significantly with time going by. The single application of chemical fertilizer or mixed application of chemical and organic fertilizers contributed to the release of DOC in top paddy soil under water-logging condition; the single application of organ- ic fertilizer promoted the accumulation of DOC in bottom paddy soil, resulting in great heterogeneity of DOC in the vertical space, but the single application of chem- ical fertilizer weakened the vertical spatial heterogeneity of soil DOC; the DOC con- tent in the 80-year-old water-logged paddy soil was higher and more stable than that in the 120-year-old soil. 展开更多

With the new pepper cultivar Guanlong as a test material, effects of differ-ent fertilizer application modes on growth and development, yield and photosynthetic characteristics of pepper were studied. The results showed that the plant height and plant expansion of pepper in T4 were the largest, of 104.3 and 90.6 cm, respec-tively. T1 showed the largest weight of single fruit, fruit length and fruit diameter, re-spectively of 101.6 g, 25.49 cm and 4.86 cm. The content of total chlorophyl in the leaves of T1 was the highest, of 66.7 mg/g, and the root activity of T1 was also the highest, of 100.6 g/(g·FW·h). The net photosynthetic rate of pepper leaves in T5 was the highest, of 6.6 μmol/(m^2·s), while the net photosynthetic rates of T1 and T2 were the lowest, fluctuating in the range of 1.3-2.5 μmol/(m^2·s). T3 showed the highest decrease amplitude of stomatal conductance in pepper leaves, of 2 658.1 mol/(m^2·s), while the decrease amplitudes of stomatal conductance of pepper leaves in treatments T2 and T5 were the lowest, fluctuating in the range of 386.7-428.7 mol/(m^2·s). T1 showed the highest decrease amplitude of transpiration rate of pepper leaves, of 4.7 mmol/(m^2·s), while treatment T5 showed the lowest decrease ampli-tude of transpiration rate of pepper leaves, of 1.1 mmol/(m^2·s). The intercel ular CO2 concentration was the highest in the leaves of T5, of 436.8 μmol/mol. T1 showed the highest plot output, yield per hectare and benefit, of 340.1 kg, 96 448.5 kg/hm^2 and 162 865.6 Yuan/hm^2, respectively, while T3 exhibited the lowest plot output, yield per hectare and benefit, of 260.8 kg, 74 338.5 kg/hm^2 and 124 888.5 Yuan/hm^2, respec-tively. 展开更多
