How to Precipitate Zanthoxylum
Many plants are developed from seeds. The germination of seeds is directly related to the growth of plants. The quality of seeds is the most important step. Without good seed genes, there can be no good plants. What kind of seed is good quality? There are several parameters for seed quality, such as grain weight, seed clarity, seed moisture, temperature, and more. The seeds required for the determination of the 1000-grain weight are the seed electronic automatic particle counting apparatus or the ordinary seed counting apparatus. Seed clarity has a special seed clarity meter, seed moisture and temperature, and can also be measured using the appropriate instrument.
Cow dung dressing, with fresh cow dung 6 to 10 copies, and 1 prickly ash seed mix, placed in a cool dry place. The cow dung and the seeds can also be stirred well, buried in a deep 30 cm pit, covered with 10 cm thick soil, cover the grass after the cover, the next spring will be taken out together with the cow dung to break with sowing. The cellar was stored in a well-soiled, well-drained area and dug into a small cell with a diameter of 1 m, a bottom diameter of 0.4 m, and a depth of 0.8 m. After the seeds were put into a 10- to 15-cm-thick seed layer, the soil was covered by 10 cm. Irrigation 1 lb, after the underwater seepage, then cover a 3 cm wet soil, cover some weeds in the pit.
In the spring of the following year, the seeds will inflate and they can sow. One block of dry seed is collected from the clod and mixed with 1 to 1.5 parts of cow dung, grass ash and loess, or 1 part of seed, 2 parts of cow dung and 2 parts of loess. The mud cake is dried and then the mud cake is dried. After putting the slurry in the mud to dry, it can be stored in a cool, dry and ventilated room. Mixed sand storage is selected for high groundwater, good drainage, digging storage pits at ventilation shady areas (bogey groundwater is too high) pit depth of 0.8 to 1.3 meters. Mix the seeds with 3 times the wet sand of the seeds. The humidity of the sand is better if the fingers can work together without water.
Chlorinated Polyethylene(CPE)
1. CPE is a kind of saturated rubber, which has excellent heat-resistant oxygen aging, ozone aging, acid and alkali resistance, and chemical resistance.
2. CPE has general oil resistance. Among them, it has excellent resistance to ASTM No. 1 oil and ASTM No. 2 oil, which is equivalent to NBR; and it has excellent resistance to ASTM No. 3 oil, which is better than CR and is equivalent to CSM.
3. CPE contains chlorine element, has excellent flame retardant performance, and has the characteristics of burning and dripping. It can be combined with antimony flame retardant, chlorinated paraffin, and Al(OH)3 in an appropriate ratio to obtain a flame retardant material with excellent flame retardancy and low cost.
4. CPE is non-toxic, does not contain heavy metals and PAHs, and it fully meets environmental protection requirements.
5. CPE has high filling performance and can be manufactured to meet various performance requirements. The processing performance of CPE is good, and the Mooney viscosity is available in a variety of grades between 50-100.
