用玻璃或塑料薄膜等透明度较好的材料全封闭式培育仙人掌类植物,确有一些比较显著的优点:一、封闭栽培可促使植株生长速度加快。通过封闭与不封闭的比较栽培实验,前者的生长速度一般可以快于后者两倍以上,且长势健壮强盛。二、封闭栽培可以促进掌类植物萌生出更多的子球,从而提高繁殖系数。在封闭的栽培条件下,较高的空气湿度进一步满足了一些易于萌发子球的种类对环境的要求,使子球的生发数量明显增多,且都能够与母球一样生长迅速。
With glass or plastic film and other materials with good transparency closed cultivation of cactus plants, there are indeed some of the more significant advantages: First, the closed cultivation can promote plant growth faster. By closed and non-closed comparison cultivation experiments, the former can generally grow faster than the latter more than twice, and grow strong and powerful. Second, closed cultivation can promote palm plants to sprout more balls, thereby increasing the breeding coefficient. Under closed cultivation conditions, the higher air humidity further meets the environmental requirements of some species that are prone to germinating, resulting in a marked increase in the number of germinal growth of the subballs and the rapid growth of the same as the cue ball.
