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 study on the characteristics of development and seed setting of different spikelet and floret positions was important for the realization of big - spike - cultural - goal with more spikelets and grains. with both the winter type ( wv ) and spring type ( sv ) varieties sown at different dates, it was found that the greater seed setting capacity of spikelets resulted in more grain number of spike. the trend of differences in grain weight per spikelet between the different sowing dates and varieties was similar to that of grain number. the correlation between the average grain weight of middle spikelets and lower spikelets and the grain weight per spike was highly significant. the environmental changes resulted from different sowing dates mainly effected the middle spikelets development, even though the differences between wv and sv were represented in every spikelet positions. the grain weight on the second floret position was most sensitive to the development status of wheat plant and environmental changes, and could represent the yielid potential of the whole spikelet. the results showed that the enhancement of seed setting of the middle spikelets ( from 5th to 15th ) and the grain development from the first to third floret positions was a key to realize big - spike and grain

This study dealt with the identification and evaluation of 8 maize populations from tropical and subtropical regions under the ecological conditions in zhengzhou, henan. results showed that the significant delaying days to shed and days to silk, discoordinating for the development of male and female, higher plant and ear height, more leaf numbers, high barreness, worse performance of ear traits compared with the ck ( temperate population ) were found, which showed the tropical and subtropical populations could not be utilized directly under the ecological conditions in zhengzhou. by using selection and improvement the tropical and subtropical populations can be used to broaden the genetic base of temperate maize breeding, beause of the greater genetic variation and higher selection potential within each population. the different performances of the sensitivity to photoperiod were observed among different tropical and subtropical populations and different traits. the asi, time to silk, ear height, leaf numbers, grain yield per ear could be used as the good evaluation traits for identifying the sensitivity to photoperiod
