Using plots with water and fertilizer fully controlled, the effect of photosynthetic characteristic and yield under different treatments of water and fertilizer coupling was investigated. the result showed that photosynthetic rates are different among treatments of water and fertilizer coupling, and the change of stomatal conductivity is the same as photosynthetic rat. there is almost no influence on evaporation rate and cellular co2 concentration the combination of fertilizer and manure under natural rainfall is beneficial to the maintenance of photosynthetic rate during grain filling, thus results in highter yield and good quality. however, the coupling of fertilizer and manure with sufficient water results in the decline of photosynthetic rate and stomatal conductivity, the yield decreased indicating there has a balance ratio between water and nutrients ( fertilizer and manure ) supply. the study proposed that the optimum management to exploring yield and qlality potential is the combination of fertilizer and manure application with no irrigation
利用可精確控制水分條件的水肥平衡場,在不同水肥耦合處理的條件下,研究了水肥耦合對玉米光合特性及產量的影響,結果表明:不同水肥耦合處理的條件下,玉米的光合速率有所不同,氣孔導度的變化與光合速率的變化表現基本一致,而對蒸騰速率、細胞間co2濃度影響不大.其中,在自然降水條件下,有機肥和無機肥的配合,有利於玉米子粒灌漿期維持較高的光合速率,表現出良好的產量潛力.充足水條件下,有機肥和無機肥的配合,光合速率及氣孔導度表現較低,表現產量有所下降,說明供水量與施肥量之間有一個平衡系數.表明黑龍江省北部黑土區自然生態條件下,為充分發揮玉米的產量潛力,最佳的管理措施是增施無機肥和有機肥的配合The relationship of the heat transfer coefficient with tea liquid concentration, heat transfer different temperature, vapor temperature, liquid flow rate, particle volume percent and different particle were studied. and analyzed the effect of liquid flow rate, particle volume percent on pressure drop. based on the character of inert particle fluidized bed evaporator, used the theorem, a mathematical model of inert particle fluidized bed evaporator heat transfer was proposed
