Hainan coconut germplasm resources The conventional classification method of Hainan coconut germplasm resources can usually be divided into three varieties: Hainan high species, Hainan dwarf species and hybrid varieties of coconuts, according to the botany characteristics of plant height and dwarf and male and female flowering stages. Through the general survey of the coconut germplasm resources in Hainan, we can see that there are 18 types of high-yield coconuts in Hainan Province, 5 types of dwarfs, and 3 types of hybrids in Mawwa. The germplasm resources are diversified. From the perspective of coconut yield, the results of the census showed that the yield of high-yield coconuts in Hainan was relatively low, while dwarf varieties of coconuts included yellow dwarfs, red dwarfs, and green dwarfs, and the yields of cross-bred coconuts were relatively high. Due to the long cultivation time, the local high-yield coconuts have been adapted to the local climatic conditions. They are generally characterized by thick trunks, well-developed roots, thick cuticles, toughness, and strong wind resistance. In addition, the local high-cold ability is stronger than dwarf species. Various varieties can be integrated into the germplasm resource bank to preserve high-quality, adaptable coconut varieties in order to better develop the coconut industry. The use of germplasm resources in Hainan can be divided into wild resources, genetic materials, breeding varieties and local varieties. The crop germplasm resource bank must have all coconut varieties to preserve or delete more adaptable coconut germplasm. Hainan is rich in coconut resources. Although the current cultivation value is not high, as a germplasm resource, it can enrich the coconut germplasm resources in China and provide new ways for future research. The quality, cold resistance and high yield of Hainan red coconut and the cold and high yield characteristics of coconut are all good materials for scientific research and have high potential value. According to the definition of "genetic material" in the United Nations "Convention on Biological Diversity", genetic material refers to any material containing genetically functional units from plants, animals, microorganisms, or other sources, and is of actual or potential value from plants, Any animal, microbial, or other source material that contains genetic functional units. The excellent genes of cold resistance, insect resistance, wind resistance, high yield, and other characteristics contained in different germplasms are all genetic materials for breeding superior varieties.
When the front terminal AGM Battery generates current, the switching power supply is a kind of power supply that uses modern power electronics technology to control the time ratio between the opening and closing of the switching tube to maintain stable output voltage. It is generally a switching power supply composed of PWM and MOET.
Batteries are often used in the manufacturing of communication, communication base station, switching power supply and so on. Usually two of lead acid batteries connection terminals set the upper corner, some specifications of the two terminals on one side long side, many people call it the outer terminal. As you can see, the usual external terminals for the bottle injection port are two rows in a row of three. In the top corner, a row of six injection ports. The technology of valve control means that the outer cover of the injector nozzle can discharge air in the middle and late stages of battery charging and cannot leak in the electrolyte conditions of the Lithium Battery.
What are the features of Front Terminal Agm Battery? Simple maintenance, safety, lithium battery life is small, long life, small internal resistance and other advantages, can be used in any direction, convenient transportation.

The outer terminal battery, also known as the slender rechargeable battery, is suitable for the pole and the outer end terminal integrated in the server cabinet. Its direction is the same as that of the rechargeable battery, and it is located at the upper end opposite the short end. The total design width of the outer terminal battery is close to the foot or foot. The basic concept and structure of the outer end battery is similar to that of the battery. With the expansion of the battery area, the outer battery has high quality heat dissipation characteristics, greatly reducing the probability of uncontrollable rechargeable battery. In addition, the external end of the battery on the external connection of the rechargeable battery has chosen the external end of the design scheme, the wiring position is in the upper part of the rechargeable battery, the connection is convenient. When the outer end battery is installed on the vertical column, the internal space of the shelf can save not only the total area of the main room, but also the installation and maintenance of the main room. The outer end cell has more advantages than the battery industry. Use the size interval guide display to walk the guide display into the room from p10 to p3.
