Effect of nutrient liquid concentration on the mechanics and growth and development of tomato leaf handle
To study the effects of different nutrient solution treatment on tomato growth, quality and leaf handle mechanics. Tomato as the test material, the use of greenhouse pearl rock matrix cultivation test, set up 3 treatment N1 (1.5 times the standard concentration of nutrients), N2 (1 times the standard concentration of nutrients), N3 (0.5 times the standard concentration of nutrition Liquid), combined with conventional measurement methods, analyzes the effect of nutrient concentration on tomato growth index, provides reference for nutrient management in matrix cultivation, and uses a texturer to bend and cut tomato leaf handles, which can provide theoretical basis for the development and development of tomato-related facilities and equipment.
The vehicle controller test system of dual-motor driving electric tractor
As the core of electric tractor, the performance of vehicle controller directly determines the power and economy of the tractor. The main purpose of the design and development of the test system was to test the CAN communication effect of the whole controller and the rationality of the established control strategy. The test system adopted modular design method, and designed the vehicle controller module, driver control module, power output module, fault monitoring module and display control module. The test system simulated the real working state of the tractor and tested the control strategy of the vehicle controller. When the load of the electric tractor changed, the control strategy would adjust the torque output of the motor in real time to ensure that the two motors are in the high-efficiency zone. The test system was used to test the vehicle controller of electric tractor, which laid a foundation for the development of the whole vehicle controller of electric tractor.
Groundnut Harvesting Methods - A Comprehensive Review
Groundnut is cultivated in most of the states of India due to favorable agro-climatic conditions and higher consumer demand. Harvesting is one of the major unit operations in groundnut cultivation because it accounts for a higher share of cultivation cost. Groundnut yields are higher for early planting and timely harvesting, and decline with delay in planting and harvesting operation. The yield loss generally ranges from 16–25% and 30–40% when harvested 10 days before and after physiological maturity, respectively. Also, pod losses are highest during harvesting compared to other operations and the cost of harvesting alone accounted for 23% of the cultivation cost. Therefore, selection of a right method of harvesting is important in groundnut cultivation to meet timeliness and cost effectiveness. In developing countries, groundnut crops are being harvested mostly by manual pulling and digging by spade, khurpi etc. and by animal-drawn diggers. While in developed countries digging is usually done by self-propelled diggers, tractor operated diggers and combine harvesters. Manual harvesting is labor intensive, time consuming, expensive and involves drudgery and can cause delay in groundnut harvesting. So a suitable mechanical harvesting system is the only solution to overcome the above mentioned problems. This article reviews different groundnut harvesting methods, development and evaluation of different groundnut diggers, losses associated with groundnut harvesting and cost economics of harvesting methods.
Coffee cultivation in agro forestry system in the non-traditional Bastar zone of Chhattisgarh
The present investigation was undertaken in the Darbha block of Bastar region in Chhattisgarh. The data's are based on three year old coffee plantations planted in 2017-2018. The results revealed the maximum under storied plant height in Chandragiri Dwarf (1.86 m) which was at par with CxR (1.82 m) and San Ramon (1.71 m) whereas CxR recorded the maximum diameter at breast height (3.72) and number of branches plant-1 (45.15). With regard to the upper storied crop agro ecosystem, silver oak recorded the maximum plant height (7.84 m) in S-8 intercropped line while the diameter at breast height in silver oak was the highest in CxR (5.58 m) intercropped lines which was at par with the intercropped lines of S-8 (5.40 m). Chandragiri Dwarf recorded the maximum under storied biomass from above ground biomass (118.41 Mg ha–1) and below ground biomass (29.60 Mg ha–1) as well as carbon sequestration recording 217.28 and 54.32 Mg ha-1 respectively from above and below ground zone. However the total carbon stock including the under storied as well as upper storied agro ecosystem was the highest in S-8 (230.43 and 57.61 Mg ha-1 respectively) followed by CxR (209.96 and 52.49 Mg ha-1 respectively).
Time Optimization when External Grinding Grey Cast Iron
This paper presents an optimization study to determine the optimum replaced grinding wheel diameter to achieve the minimum machining time when external grinding grey cast iron. In this study, several main input process parameters including the initial grinding wheel diameter, the grinding wheel width, radial grinding wheel wear per dress, the total depth of dressing cut, and the wheel life were investigated. The influence of these parameters on the optimum replaced grinding wheel diameter was analyzed by using Minitab software. In addition, a regression formula to determine the optimum replaced grinding wheel diameter when grinding grey cast iron has been introduced.
