四季豆,本地在小寒至大寒间播种,是时多低温干旱,出苗率低,苗期生长缓慢,早播常不早收、多收.为此,通过地膜覆盖栽培,以求减轻低温干旱对其出苗及苗期生长的不良影响,达到早熟、高产,增收的目的.试验设五个处理:地膜、蓝色薄膜、白色薄膜及稻草覆盖栽培,以露地栽培为对照.蓝色、白色薄膜均为普通农用薄膜.
Green beans, local Osamu Osamu sowing, is the time of low temperature and drought, low rate of emergence, seedling growth is slow, often do not early harvest early, and more income.To this end, through the plastic film cultivation, in order to reduce the low temperature and drought Its emergence and seedling growth adverse effects, to achieve the purpose of early maturity, high yield, increasing income.The experiment set five treatments: film, blue film, white film and straw covered cultivation, open-field cultivation as a control.White, white film For ordinary agricultural film.
