What are the control methods for watermelon malformation?
1. Artificially assisted pollination: When artificial pollination, the pollen scattered on the stigma should be uniform, and the pollen should be sufficient to ensure complete pollination. 2, appropriate increase of the melon parts: According to the investigation, the fruit of the first female flower of watermelon, the shape is not correct. For this reason, in production, it is generally preferred to leave the second and third female flowers on the main vines about 1 meter away from the main root. 3. After the young melon is stable, the melon is placed in time: the soil under the young melon is flattened and made into a slope-shaped high platform, and the young melon is placed on the slope. As the young melon grows, the slope gradually increases. 4. Turn the melon and the vertical melon in time: After the fruit is “fixedâ€, turn the melon once every 3-5 days, and turn it around 1/3 each time; when the fruit is ripe until the ripening of the seven or eight, the melon is erected. Turning melons and melons can make the fruit develop round and even skin color, thus increasing its commercial value. 5, timely watering, fertilization: to meet the needs of fruit growth and development. 6, timely prevention of pests and diseases: minimize mechanical damage. For the malformed melon that has been formed, it should be removed early to encourage the plant to sit again.

Laser distance measure is a very convenient
tool for various types of applications in industries, construction and house decoration.
Laser distance meter is a very useful device which gives accurate measurement
of distance, area and volume especially in large areas such as rooms,
apartments, buildings, real estates, factories, warehouses, infrastructures, gardens,
roads, and many other applications requiring accurate results for distance ,
area and volume measurement.
Trade your heavy tape measure for laser
rangefinder, which let you simply take measurements with one hand. No matter
your job, the laser rangefinder will help you measure much farther, with
greater accuracy and in more situations, saving you money and time.
