某些与禾谷类根系共生的微生物能固定大气中的氮,故当栽培介质缺乏有机碳时,并不影响其生长和活性。为了确定固氮螺菌(Azosprillium)的作用,对雨季高粱(CHS-5)进行了种子包肥研究。分析的参数有籽粒产量、稿秆产量、至半花期日数、单株粒重和千粒重。施氮量达到每公顷80公斤时,籽粒产量在二年的试验中都增加了。随着施氮量的逐渐增加,籽
Some microorganisms that coexist with cereal roots can fix nitrogen in the atmosphere, so when the culture medium lacks organic carbon, it does not affect its growth and activity. In order to determine the role of Azospirillum, a seed-wrap study of sorghum sorghum (CHS-5) was conducted. Analysis of the parameters of grain yield, draft straw yield, to the number of flowering days, grain weight per plant and 1000-grain weight. At nitrogen up to 80 kg ha-1, grain yield increased in two years of testing. With the amount of nitrogen applied gradually increased, seeds
