近年来,琦玉县茄子的促成和半促成栽培等保护地栽培虽有增加,但早熟小拱棚栽培、普通栽培和抑制栽培等露地栽培仍占很大比重。在保护地栽培中,由于收获期正处于冬春季节的低温时期,叶螨类增殖缓慢。与露地栽培相比,此时劳动力比较充裕,要彻底防治是容易做到的。因此,叶螨类的为害不会成为太大的问题。 In recent years, Saitama County, eggplant and semi-promoting cultivation and other protected areas despite the increase of cultivation, but early cultivation of small shed, common cultivation and suppression of cultivation and other open-field cultivation still accounts for a large proportion. In protected cultivation, the spider mites proliferate slowly because the harvest period is in the low temperature period of winter and spring. Compared with the open field cultivation, labor force at this time more abundant, to completely prevent and control is easy to do. Therefore, the damage caused by spider mites will not become too much of a problem.
