The cultivation of broccoli:
Soil fertilizer
Soil fertilizer is very important, which directly affects the growth of broccoli, so it must be adjusted. If the soil pH is lower than 6.0, you can use acid compost or mixed fertilizer. If the soil pH is higher than 7.0, you can add sulfur particles. It is also possible to add mature compost to the soil. If the soil is poor, it can also add organic fertilizer with high nitrogen content. This principle must be remembered. To follow this principle, we can better plant broccoli.
2. Sowing
Broccoli wants to be harvested well, sowing must be timely. Generally, broccoli must be harvested in the summer for two to three weeks before the last spring frost. The broccoli in the autumn harvest must be planted indoors and outdoors directly 85-100 days before the first autumn frost. This sowing principle is very important, and it is necessary to master and follow it in time to better grow broccoli.
3. Field management
Field management is very simple, mainly for fertilizer and water. Master the management method of fertilizer and water. If it rains, it should be drained in time.
4. Disease prevention
The disease control of broccoli is very simple, because the disease of broccoli is relatively small, and it is generally possible to use targeted pesticides for control.
A melt flow index (MFI) tester is a laboratory instrument used to measure the flow properties of thermoplastic materials. It is commonly used in the plastics industry to determine the melt flow rate (MFR) or melt volume rate (MVR) of a polymer.
The MFI tester consists of a heated barrel with a die at the bottom. A known weight of the polymer sample is placed in a heated cylinder, which is then pushed through the die under a specified load. The flow rate of the molten polymer is measured and recorded, usually in grams per 10 minutes.
Different types of MFI testers are available, including manual, semi-automatic, and fully automatic models. Some advanced models may also offer additional features, such as temperature control, data logging, and automatic calculation of MFI values.
