Plant residues harvested in floating culture system as tomato seedling substrate 漂浮栽培系統(tǒng)收獲植物殘?bào)w作為番茄育苗基質(zhì)的應(yīng)用研究
The plant residue decomposing simulated experiment in containers is managed according to those general properties afterward with aims to test and verify them 0和ss3 ,而冬水免耕處理的土壤有機(jī)質(zhì)的增幅不大。
As we all know : the chief part in decomposing the plant residue is soil microbe . it ' s microbe ' s metabolism that promotes the turnover of substance and organic matter in soil 土壤微生物是影響有機(jī)殘?bào)w分解利用的最主要的因素,是推動(dòng)土壤有機(jī)質(zhì)分解、轉(zhuǎn)化和循環(huán)的動(dòng)力。
This study takes the relationships between the turnover of organic matter and microbe as its goat by researching the course of plant residue decomposition and mineralization 在本論文中,有機(jī)殘?bào)w的分解是自始至終的研究內(nèi)容,有機(jī)殘?bào)w的分解、轉(zhuǎn)化與微生物的關(guān)系是論文的研究中心。
Organic matter is higher at the soil surface because plant residues from either grasslands or no - till are left on the surface whereas residues in conventional fields are mixed in the soil ; giving uniform organic matter 在草地和免耕方式下,植物殘?bào)w留在土表,所以表層土壤的有機(jī)質(zhì)含量較高,而在傳統(tǒng)耕作制下,植物殘?bào)w被翻入土內(nèi),所以各層土壤中有機(jī)質(zhì)含量差別不大。
