To solve the problems of high rhizome damage and low net cutting during carrot combine harvesting, following research was performed. The designed stem- leaf-cutting device taken as object, a bionic design idea adopted. MATLAB software used to extract optimize tibial curve mantis forelimb, its shape applied edges single-disc rotating cutter straight fixed cutter, whose key structural parameters ...

The successful rootingof leafy cuttings inivolves three physiologieally distinct processes: initiation of root primordia; development of true roots from these initials; and mainitenance of the cutting as ani excised organ during the rooting. The first of these, where it does niot take place sponitanieously, cani be brought about in many plants by treatment with auxini. The second (outgrow^th of...

this experiment was conducted to study the effects of single and combined application of organic, biological and chemical fertilizers on qualitative and quantitative characteristics of vegetative part of coriander, (coriandrum sativum l.). the experiment was carried out as split plot in time based on complete randomized block design with three replications and 12 treatments at research station,...

The objective of this study was to assess the effect of applying N and K2O at different times after harvest on the structure and production characteristics of Marandu and Xaraés cultivars of Brachiaria brizantha. Two greenhouse 4 × 2 factorial experiments using a randomized block design with eight treatments and four replicates were carried out. In experiment 1, the plants in pots were fertiliz...

objective: evaluation of the effect of propolis as a bioactive material on quality of dentin and presence of dental pulp stem cells. materials and methods: for conducting this experimental split-mouth study,a total of 48 maxillary and mandibular incisors of male guinea pigs were randomly divided into an experimental propolis group and a control calcium hydroxide group. cutting the crowns and us...

In the laser cutting process some well-known parameters, e.g. laser power and cutting speed, play major roles in the performance of the process. Each parameter or a combination of parameters can affect the material removal volume and cutting volume efficiency. The purpose of this research is to study the effect of power and maximum cutting speed on the material removal rate (MRR) and cutting vo...

vibration cutting (vc), elliptical vibration cutting (evc) and ordinary cutting (oc) of in738 work-pieces have been experimentally investigated in the present research. the experiments were carried out by using single crystal diamond tool and ultra-precision cnc lathe. vibration frequency is 36.16khz and the amplitude is . the influence of various cutting parameters including cutting speed, fee...

Limitations of cuttings become an essential problem in the expansion cassava plantations. One strategy that can be taken is to reduce length and increase plant population area planted produce more stems per unit for next growing season. This study aimed determine effect cutting hectare on growth production stems. The research was carried out at Jambegede Agricultural Technology Research Assessm...

To investigate the optimal parameters combination of reciprocating cutter for harvesting hydroponic lettuce automatically, a shear fixture was designed cutting stems on universal materials tester. Effects blade distance, sliding angle, skew and shearing angle stress were investigated in this study. The orders significance single factor double factors analyzed using response surface methodology ...
