Soil structure degradation in greenhouse vegetable fields reduces vegetable production. Increasing aeration porosity is the key to ameliorating soil structure degradation. Thus, we tested the effect of a porous material, porous clay ceramic(PLC), on the a
Portable X-ray fluorescence(pXRF) spectrometry and magnetic susceptibility(MS) via magnetometer have been increasingly used with terrain variables for digital soil mapping. However, this methodology i
Recently,biochar has shown to be an alternative to waste disposal and a source of nutrients,acting as a soil amendment.The effects of two types of biochar on so
选育一个优良的玉米品种,在北方需要经过十几年左右的时间,为加快新品种培育速度,缩短玉米育种年限,海南南繁成为玉米育种不可缺少的一项重要环节,根据黑龙江省农垦科学院在海南省三亚市崖城镇南滨农场的多年南繁育种实践,阐述了玉米冬季南繁育种的内容和方式并对玉米育种的几点关键技术环节进行总结归纳,以供育种工作者进行参考。
The use of green manures contributes to sustainable soil and nutrient management in agriculture;however, the responses of soil microbial communities to different fertilization regimes at the regional scale are uncertain. A study was undertaken across mult
通过中盐红四方玉米缓释肥和常规施肥对比试验,研究中盐红四方玉米缓释肥在玉米上的应用效果。结果表明,中盐红四方玉米缓释肥比常规施肥增产667.5kg/hm2,增产率5.3%。
The Soil Land Inference Model(SoLIM) was primarily proposed by Zhu et al.(Zhu A X, Band L, Vertessy R, Dutton B. 1997. Derivation of soil properties using a soil land inference model(SoLIM). Soil Sci Soc Am J. 61: 523–533.) and was based on the Third Law
该研究于2016~2020年开展大豆-玉米-玉米-大豆-玉米的轮作方式,采用玉米秸秆深翻还田(25~30cm),玉米秸秆粉碎-打茬-深翻-耙茬、大豆茬采用深松整地的耕作方式。设置8种施肥处理,通过对大豆及玉米不同生育期性状及产量调查,探讨黑龙江省大豆在轮作模式下如何减少化肥用量、优化资源配置,为大豆增产增效和农业可持续发展提供科学依据。
