| 摘 要： | 对果棉间作的香梨幼园和间作的棉田,进行了土壤水分、生长和生理状况的比较。在5月份,对香梨进行沟灌则只增加棉田80 cm以下的土壤贮水量,不影响棉花的蹲苗。在整个生长期内,灌溉的时效关系没有影响香梨和棉花的正常生长和生理状况。在全年生长期蒸散量的基础上,香梨幼园整合了的灌溉制度应是全年的净灌溉量10687.5 m3/hm2,灌溉7次,除5月20日对香梨专门灌水562.5 m3/hm2外,其余皆1687.5 m3/hm2。

| Abstract: | This paper studied and compared that soil water, status of physiological and growing of the plants, which planted in the irrigation ditch and cotton fields between them, in the mix-planted garden. The irrigation to fruit tree in May do nothing to cotton growth but increase the water pondage under 80 cm earth level. The relationship between irrigation time and its effect did not affect the status of physiological and growing of the pear and cotton in the whole growing periods. The irrigation system and pure irrigation amount, based on the evaporation in the whole growing year, conform to 10687. 5 m^3/hm^2 for 7 times. The irrigation amounts, different from plants, are 1687.5 m^3/hm^2 in each time except special irrigation to pear with 562.5 m^3/hm^2. |
