The garden pansy is a type of large-flowered hybrid plant cultivated as a garden flower. It is derived by hybridization from several species in the section Melanium ("the pansies") of the genusViola, particularly Viola tricolor, a wildflower of Europe and western Asia known as heartsease. Some of these hybrids are referred to as Viola wittrockiana Gams ex Nauenb. & Buttler. For simplicity, the older name Viola tricolor var. hortensis is often used.
The garden pansy flower is 5 to 8 centimetres (2 to 3 in) in diameter and has two slightly overlapping upper petals, two side petals, and a single bottom petal with a slight beard emanating from the flower's center. These petals are usually white or yellow, purplish, or blue. The plant may grow to 23 cm (9 in) in height, and prefers sun to varying degrees and well-draining soils.

Agricultural machinery maintenance should pay attention
1 Sliding bearing non-scratchable engine crankshaft bearings and connecting rod bearings must be scraped with, it does not seem to scratch can not guarantee a good contact surface, even the new crankshaft, standard tile also scraping, I do not know some small engines, crankshaft bearings The wear-resistant alloy coating of the connecting rod bearing is very thin, it does not allow scraping and can only be matched according to the regulations. 2 The water temperature of the engine is not afraid of high, and the temperature of the water is found to be high, and all possible means are found to eliminate the cause. If the water temperature is low, it is considered correct. In fact, the low water temperature hazard is also very large, resulting in inadequate fuel combustion, resulting in reduced power, increased fuel consumption, poor lubrication, and increased charcoal collection in the combustion chamber. 3 plus more oil Ning Do not think less easy to burn bearings, more and more little relationship, in fact, more oil added to the same engine damage, increase the resistance of the crankshaft and connecting rod movement, splashes of oil on the cylinder wall increased, Into the combustion chamber, resulting in increased carbon collection, affecting emissions. 4 The amount of butter in the hub should not be less than the total amount of butter in the hub is considered to be the best. In fact, this is a waste of butter. Second, the butter can easily distort the oil seal or paper pad after heating, but also affect the heat dissipation.
