据《中国农业科学》2014年第19期《炭化秸秆对苹果根系一氧化氮生成及根区土壤硝酸盐代谢的影响》(作者闫丽娟等)报道,在春季,将炭化玉米秸秆与土壤按照0.5%~8.0%(W/W)的比例混匀后装入陶盆,然后将生长势相近的3年生“富士”苹果幼树(砧木为平邑甜茶)移栽到陶盆中,于移栽120~190天后定期检测苹果根系和根区土壤NO生成速率以及硝酸还原酶(NR)的活性,并分别测定根系一氧化氮合酶
According to “China Agricultural Sciences” 2014 No. 19 “carbonized straw on the root growth of nitric oxide and nitrate metabolism in the root” (the author Yan Lijuan, etc.) reported that in the spring, the carbonized corn stalks and soil in accordance with 0.5% ~ 8.0% (W / W), and then potted three-year-old “Fuji” apple seedlings (rootstock of Pingyi sweet tea) with similar growth potential into pots, After 120-190 days of planting, the NO production rate and nitrate reductase (NR) activity in root and root apples were detected regularly. The contents of nitric oxide synthase
