Horticultural materials are tools needed in the process of plant horticulture, which can help the plant seeds to thrive, such as nutrient bowls, which can play a protective role for plants, such as mulch, ground cloth, and also containers plant bags that facilitate the movement of plants by growers.
Nutrient bowl: Nutrient bowl is made of polyethylene as raw material, with certain specifications, shaped like a teacup metal mold at a certain temperature by stamping processing and the formation of the bowl. Its specifications: the diameter of the bowl from 8 cm to 13 cm, the height of the bowl 8 cm to 13 cm, the diameter of the bottom is relatively small than the diameter of 1-2 cm, the bottom of the bowl has a small round hole in the center, the aperture of about 1 cm, in order to drain. Used to hold into the loose fertile soil of ungrown vegetables or well-prepared nutrient soil for root nursery. The choice of volume size depends on the variety of seedlings and the size of the seedling age. For example, eggplant and melon seedlings, if the age of seedlings in 20-30 days or less, can choose the pot diameter 8 cm nutrition bowl; if the age of seedlings in 30-40 days or less, can choose the pot diameter 10 cm nutrition bowl; if the age of seedlings in 50-60 days, can choose the pot diameter 13 cm. Melons such as bitter melon, knotted gourd, zucchini to be harvested early before the end of April, and in early March transplanted to the field, must be in early January seedlings, seedling age up to about 60 days, therefore, must choose the bowl diameter of 13 cm.

　　Mulch: First, choose according to the regulations. There are strict national regulations on the thickness of mulch: 0.014mm for mulch, 0.008mm for microfilm, and 0.005mm for super-microfilm. The recent national standard strictly prohibits the use of mulch below 0.008mm, which means that super-microfilm is prohibited, first of all because of the white pollution problem, because although the price of too thin mulch is reduced, it causes serious white pollution. But it will cause serious white pollution. After it is laid, it will form small pieces under the sunlight, so it is not easy to recycle, causing residue in the field, and when it is cultivated, it is buried in the ground, which is difficult to remove and is not good for late vegetable production. Second, repeatedly pull and test the mulch. Good mulch, with good horizontal and vertical pull, cuts a small strip of mulch and can stretch 2-3 times when stretched and still not break. Poor quality membranes are brittle and can easily crack or even break during stretching. High quality film is resistant and remains very soft in the cold winter months, while regular film becomes hard and has white marks when folded slightly. A good insulation film will turn white where it is stretched, and transparent where it turns white if pulled repeatedly, indicating high insulation, while a normal film will not have this effect.
