描述:
enteenth giving us the
overall vision on the development of rural reform, has important and far-reaching significance.
The Decision emphasizes the need to accelerate agricultural scientific and technological
innovation in the new period and leading in the direction of agricultural technological
development.It is an important task to promote rural reform and development.
描述:
be given when fully and rational use of local
climatic resources such as solar radiation, heat and water, while other conditions (such as soil
fertility, carbon dioxide concentration, cultivation level etc.)
描述:
siea. Low temperature is the key factor that limits
the growth, colour and appreciatability in winter in the northern of China. Introducing foreign gene
into kale through genetic engineering may create novel variety with cold tolerance. In this study,
BADH(encoding betaine aldehyde dehydrogenase) and TCH(encoding transcription regulation
factors) were used to be transformed into kale with Agrobacterium-mediated transformation.
描述:
ogical characteristics of
the crops and people’s production and business activities, largely dominated by light,
heat, water, gas and other climatic factors.
描述:
th, the demand of water resource is
continuously increasing. That is to say water shortage has become a global problem. Water
resources carrying capacity is the basis and prerequisite of regional socio-economic development,
which is significant to realize the coordinated development of regional "water resources-
ecological environment-socio-economy" composite system. So it has become the focus and hot
topic in water science field nowdays.
描述:
conducted full irrigation (CK),
mild regulated deficit irrigation and moderate regulated deficit irrigation with melon varieties
of Ymdi and Yujinxiang in three growth stages including sowing to flowering time, flowering
to fruit expanding stage and fruit expanding to picking time.
