(l) Choose different types of violets. Such as spring violet, summer violet, autumn violet, adopt the staged sowing method, there will be flowers in the warm area from spring to autumn.
(2) Use different sowing dates to extend the flowering period. If planted in the greenhouse in early February, it can bloom in May; in the greenhouse, it will be planted in late February to March, and it will bloom in June; in April, it will be planted in July, and will be planted in July. Flowering in the month; planting in the second half of July of the previous year, it can bloom indoors from February to March of the following year. The sowing temperature is 16~18 °C, and the seedlings should not be too dense, otherwise the seedlings are vulnerable to the disease. In addition, some tall varieties of flowers after the flower cut off the residual flower branches, timely application of 1 or 2 times of top dressing, can reproduce the side branches, can bloom again.
Violet can also be used to promote flowering.
(1) Electric lighting. Violet is a long-day plant, and winter greenhouse cultivation can promote flowering by extending the light.

It is advisable to install the light lamp about 1 meter above the top of the plant.
(2) Gibberellin treatment. Before and after flower bud differentiation and in the middle and early November of the differentiation, spraying the flower buds with 50 ml/L of gibberellin also produced an effect of promoting flowering.
Resin bond is a kind of organic bond, the grinding wheel made of this bond has high strength, has certain elasticity, low heat resistance, good self-sharpening, easy production and short process cycle. It can manufacture Grinding Wheels with working speed higher than 50 m/s and very thin grinding wheels. Its application range is second only to ceramic binder, widely used in rough grinding, waste grinding, cutting and free grinding, such as grinding steel ingot, casting burr etc.. Can manufacture high speed, high finish grinding wheel, heavy load, cutting and various special requirements of grinding wheel.
In tool grinding, the cutting tool materials with high hardness, thermal hardness, wear resistance and enough strength and toughness, such as carbon tool steel, alloy tool steel, high speed steel, hard alloy, etc., are grinded with resin strong grinding wheel to achieve ideal accuracy. The surface roughness and correct geometry make the cutting edge have high sharpness and durability
