The shape of the watermelon is not only affecting the aesthetics of the watermelon but also affecting the taste, so it will greatly reduce its quality, and it will not sell for a good price. Next, Xiaobian will summarize how to prevent the watermelon fruit shape from being prevented in advance. .
Preventive measures for watermelon fruit shape:
1. Artificial assisted pollination of watermelon fruit shape prevention method
Preventing watermelon fruit shape in advance is about to start from pollination. It is not enough to rely solely on its own pollination, but remember that the artificial pollination must be uniform and the amount should be sufficient to ensure that the watermelon pollination is more uniform.
2. The preventive method of watermelon fruit shape is appropriate to improve the position of watermelon melon
Generally, the fruit of the first female flower knot is not good, and the fruit shape is not correct. Therefore, in the planting process, the 2.3th female flower fruit on the main vine about 1 meter away from the main root should be selected, which can effectively avoid the watermelon fruit shape. Not correct.
3. Watermelon fruit shape prevention method of watermelon
Under the young melon, use a fine soil to make a slope-shaped high platform. Place the young melon on the slope once. When the watermelon grows properly, gradually increase the height to keep the watermelon growing better.
4. Timely prevention of watermelon fruit shape prevention method
After setting the fruit in the watermelon, you should turn the melon regularly and flip it for a little while. When the watermelon is about to mature, you should put the melon up, which can make the watermelon skin look more beautiful, better looking, and effectively prevent the watermelon fruit shape from being corrected. .
5. Preventing pests and diseases from the preventive method of watermelon fruit shape
In the watermelon planting, it is necessary to fight drugs to control the shape of the watermelon. If you see the deformed melon, you can remove it.
Sealand is a trustworthy manufacturer of Gas Mass Flow Meter, Gas Mass Flowmeter, Gas Flow Meter, Gas Flowmeter, Gas Meter, ATEX, IECEx & CE approved.
The installation is as follows.
1. Installation Steps
a) Choose correct installation site, taking installation area, pipeline, transmitter location &
valve location into consideration;
b) Install the meter according to direction mark on sensor;
c) Install the sensor & transmitter on pipeline;
d) Connect transmitter & sensor with 9-pin cable;
e) Start.
a) Sensor stays away from mechanical vibration source, for example, pump. Use flexible pipe to connect meter with pipeline if inevitable. The housing of meter must be standalone, out of touch with any other device. There must be 3 times the size of sensor between 2 sensors if there are many flow meters on the same pipeline, to avoid resonance.
b) Do not install sensor on pipeline that easily expands with hot and contracts with cold, especially near expansion joint, which leads to a worse stability.
c) Sensor stays away from industrial electromagnetic field, such as large generator and transformer, better 5m at least. Such device influences the performance of drive coil and pickoffs. Make sure magnetic field intensity less than 400A/m.
d) Sensor shall be installed on lower pipeline, to be easily full of fluid.
e) Make sure Ex-mark meet application requirements if in hazardous area.
f) Build a sunshade if the meter is under direct solar radiation. g) Keep the meter from corrosive liquid.
