曲柄摇杆式深施机构的设计与施肥性能试验研究

In response to the poor fertilization performance of the deep application mechanism of the deep application liquid fertilizer applicator under multiple parameters, the fertilization variation of the crank rocker deep application mechanism under multiple working parameters is explored. To obtain the fertilization variation of the crank rocker deep application mechanism, a fertilization performance test bench for the crank rocker deep application mechanism is developed. On this test bench, the crank speed, liquid pump pressure, and spray hole diameter are used as experimental factors, and fertilizer application rate is used as experimental indicators. A composite design scheme of rotation center is adopted to establish a relationship model and response surface diagram between experimental influencing factors and influencing indicators. Design Expert 8.0.10 software is used to analyze and optimize the experimental data. The optimal results are a crank speed of 145.80 r/min, a liquid pump pressure of 0.25 MPa, a spray hole diameter of 3.02 mm, a fertilizer application rate of 28.6 mL, and a fertilizer loss rate of 1.9%. At this time, the fertilization performance of the mechanism is optimal. This parameter combination is applied for testing and verification to verify its rationality. The results can ensure that the crank rocker deep application mechanism has good working performance when working under multiple parameters, providing theoretical reference for designing deep application liquid fertilizer machines with simple structure and optimal fertilization performance.

Electrical conductivity based algorithm for precise application of liquid nitrogenous fertilizers

Precise application of nitrogenous fertilizers mainly urea ammonium nitrate (UAN) and granular urea (both pure and neem-coated) in aqueous form, is critically important for basal and foliar applications. The physicochemical properties of aqueous solution of these nitrogenous fertilizers plays important role in design of any liquid fertilizer application system. The study was carried out during 2019–20 at ICAR-Indian Agricultural Research Institute, New Delhi with an aim to develop algorithms for use in sensors-based systems for real time monitoring of available N concentration in the fertilizer solution before its application. The physicochemical properties like pH, electrical conductivity (EC), specific gravity (SG), dynamic viscosity (DV), surface tension (ST) and percentage light absorbance (LA) of urea ammonium nitrate (UAN-28%), pure urea, and neem coated urea in diluted form (pre-selected N-concentrations i.e. 0.78, 0.9, 1.08, 1.33, 1.75, 2.54 and 4.67% corresponding to the dilution ratios of 1:35, 1:30, 1:25, 1:20, 1:15, 1:10 and 1:05) were measured and analyzed for their significance with N-concentration. Electrical conductivity (EC) alone showed a significant relationship with N-concentrations. Prediction models were developed for diluted UAN and granular urea fertilizers based on the EC and N-concentrations. The regression models in terms of EC to predict N-concentration had coefficients of determination (R2) of 0.998, 0.998, and 0.999 for diluted UAN, pure urea, and neem coated urea with water, respectively showed a great potential for their sensor based precise application. The controlled application of diluted liquid fertilizers with water can be achieved through sensing relevant physicochemical property.

Effect of spent engine oil pollution and liquid organic fertilizer application on soil chemical properties and nutrient contents of Maize (Zea Mays)

A trial was conducted to evaluate the effect of spent engine oil (SEO), bio-treated with liquid organic fertilizer, on maize plant growth. The study utilized three concentrations of SEO (0.5 and 10% w/w) and four liquid organic fertilizers (water control, cattle dung, poultry manure and rabbit manure). These factors were arranged in a 3 × 4 factorial setup with three replications in a completely randomized design. Collected data included percentage moisture, dry weight, nutrient content and uptake, heavy metal concentration, and post-harvest soil chemical properties. Soil composite samples on physical and chemical analysis carried out show that the engine oil pollution negatively affected soil pH, total nitrogen, available phosphorus, and exchangeable cations, but it increased total organic carbon before maize cultivation. The percentage moisture and dry weight of the maize plant were not significantly (p > 0.5) influenced by engine oil pollution or liquid organic fertilizer application. N, P and Mg content of maize plant were significantly reduced by the engine oil pollution but significantly boosted by organic fertilizer application. Cr and Pb content of the maize were increased with engine oil concentration but decreased with liquid organic fertilizer. Nutrient uptake was decreased with increase in engine oil content but increased with liquid organic fertilizer application. At the end of the experiment, engine oil pollution significantly depressed pH, total N, available P and exchangeable cations, but increased organic C, total hydrocarbon, exchangeable Al and heavy metal content while it was opposite for liquid organic fertilizer. Our findings suggested that soils polluted with SEO should be corrected with the application of organic fertilizers.

Effect of Foliar Application of Potassium Fertilizer on Yield, Fruit Quality, and Cold Hardiness of Vitis spp. ‘Chambourcin’

ABSTRACT Temperate regions experiencing sub-zero temperatures negatively impact grapevine yield. Potassium has been claimed as a cryoprotectant to improve cold hardiness in grapevine. This study investigated the effect of foliar application of liquid potassium-based fertilizer, ReaXTM, on cold-hardiness of grapevine Vitis spp. “Chambourcin” along with its effect on yield and fruit quality. The vines were sprayed four to five times between the fruit set and veraison stage at a concentration of 1.5% (v/v) for two consecutive seasons. Petioles were analyzed for nutrients, clusters for yield and fruit quality, and cold hardiness was determined by differential thermal analysis and bud injury assessment. Potassium deficiency was observed in all treatments, and its content did not increase significantly in treated vines. Berry potassium levels and total soluble solids were generally higher in K-treated vines, however, there was no significant effect on yield and other fruit quality traits. Significant differences in cold hardiness levels were observed in both dormant seasons. Foliar application of potassium is a promising cultural practice to increase cold hardiness, but further studies are needed to understand the limits of its effectiveness.

Therefore, this study aimed to evaluate the application of cost-effective nitrogen management strategies in organic common bean cultivation, including the application of poultry manure and organic liquid fertilizer, seed and co-inoculation with diazotrophic bacteria (Azospirillum brasilense and/or Rhizobium tropici), and supplementary Rhizobium tropici inoculation. The study spanned three years in a well-established organic cultivation field (2018) and an initial organic cultivation area (2019 and 2020) in Brazil. It was arranged in a randomized blocks design in a 2 × 5 (2018) and 2 × 6 (2019 and 2020) factorial scheme, with four replicates. The most profitable strategy involves seed inoculation with Azospirillum brasilense and additional inoculation with Rhizobium tropici at stage V4-5 (fifth trifoliate leaf fully expanded), while the most costly strategy was the application of poultry manure at the V3 stage (first trifoliate leaf fully expanded). Thus, the use of diazotrophic bacteria for seed inoculation and co-inoculation (Azospirillum brasilense and/or Rhizobium tropici) ensured financial returns and system profitability in common bean cultivation.

Alternative Methods for Handling Iron (Fe) Deficiency of Oil Palms (Elaeis guineensis Jacq.) Grown in Sandy Soil

Iron (Fe) deficiency is one of the general problems that occur in Oil Palms (Elaeis guineensis Jacq.) which are planted on sandy soil. Fe is an important micronutrient in enzyme activities, including cytochromes in the process of electron transfer, chlorophyll synthesis, and in maintaining the chloroplast structure. The research was conducted in 2 series of field observations. The first observation was conducted on the application of clay mineral soils (Plinthic Kanhapludults and Lithic Dystrudepts) in a silt pit, while the second observation was on the application of liquid nano-sized Fe fertilizer through root infusion and trunk injection methods, in addition, Fe chelated fertilizer application were also observed. The observation variable was the level of Fe in leaves 17th. The results showed all treatments significantly increased levels of Fe in leaves with different plant response rates. Root infusion treatment shows a faster response than clay mineral soil treatment, namely at 2 - 4 months after application (50.3 ppm and 38.2 ppm). Meanwhile, clay mineral soil treatment has a slower plant response rate on increasing Fe level in the leaves with a significant difference against the control, precisely at 24 months after application. Normally, regular Fe fertilization is enough to fulfill plant nutrient needs. Application of Fe through trunk injection or root infusion can be an alternative treatment for short-term use, whereas the application of clay mineral (iron-rich) soil can be optional for long-term needs.
