- Fresh seeds have a fully-developed embryo and a water-permeable seed coat and endocarp, and they require >4 wk to germinate in a warm temperature regime. 新鲜种子具有发育完全的胚,以及水分可通透的种皮和内果皮,但它们却需要4周以上时间才开始发芽。
- Plastic mulch increases soil temperature in the bed which promotes faster crop development and earlier yields. 塑料薄膜覆盖提高苗床的土壤温度,促进作物较快发育并提早成熟。
- Marine sediments on the continental slope of the NE South China Sea have appropriate thickness, methane-generating potential, and occur in a suitable pressure temperature regime to host gas hydrate. 摘要南中国海东北部大陆斜坡带上的海相沈积有适当的沈积厚度,处于适宜形成气水合物的温-压域内,有一定的甲烷生成潜力。
- Meanwhile, the soil temperature under NTS affected the dry material accumulation of the crop. 同时,免耕覆盖下的土壤温度影响到作物干物质的积累。
- Dissipation increased with soil temperature and decreased with increasing depth in the soil profile. 消散随土温增加,随土壤剖面变深而减少。
- Emergence does not only depend on soil temperature but also a function of variety. 出苗不仅取决于土壤温度,而且还取决品种的特点。
