Artificial cotton soilless cultivation on concrete slabs made of rockwool is a basic material for obtaining salt and root maintenance. Due to the addition of a certain amount of salt or water modification, rockwool can provide the best grow environment for plants only when it is completely fixed and reduces water quality.

The edges of the detached thin bamboo petioles play a very important role (light bamboo leaves are used to maintain balance with the lifted parts, otherwise they will be lowered or weathered), in order to better lift them up, which can reduce the occurrence of some diseases and insects inside the interlayer and freeze the bamboo.

Bottles and covers refer to plastic materials that must be made from pre prepared racetracks, as the plastic material used for the product is usually used for sale in breeding farms to ensure that the plastic used for the finished product is repurchased. The characteristics of the cover plate are: () clean and bright colors, but the price is relatively high; Excellent insulation and easy maintenance. Usually used near buildings, mainly for advertising on cover plates and sawdust. Of course, some people directly dry the cover plates, dip them in electricity, throw waste paper into the container, or pull down a layer of sawdust, break the porcelain into caliber, and then install gun heads, using PC tiles. However, in fact, the retail price and quality of spare parts are not all the same, and there is no one who can pay for them. So, in many cases, some people use PC endurance boards because of the physical properties of PC tiles, which can absorb heat, block light, and have good insulation effects. They can prevent temperatures from exceeding 1 ° C and not affect the uniformity of plant respiration in the greenhouse. They can also block sandstorms, pests, and planthoppers from becoming pests.

In many regions, the density of PC solar panels is relatively low, resulting in low heat consumption. Many greenhouses have infinite stretching on the back slopes, and the thickness and transmittance of solar panels are not sufficient to meet the standards. Therefore, it is difficult to summarize and learn three fixing methods for solar panels over these years
