  3. 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
  4.

    綜觀國內外有關研究，我們認識到對紫色土土壤產流和水分變化特徵的認識，是認識該區土壤侵蝕與保護、農田水量平衡、非點源污染等的機理和規律的基礎，也是解決該區水患問題、實施徑流調節而提高旱地的雨水利用程度，以及水肥管理等的基本科學依據。因此，以水文學原理為基礎，採取水文學與土壤學、地理學、水土保持學等相結合的途徑，研究紫色土坡耕地的降雨產流機制與產流後土壤水分的變化特徵，是具有新的科學價值和現實意義的。
  5. On one hand, agricultural products supply has turned from being in shortage to a basic balance in total amount, and after our country joins wto, the agricultural products will face the fierce international market competition, and market demand is larger and larger to the engagement which agriculture will be developed ; on the other hand, with the abuse of chemical fertilizer and agrochemicals, the agricultural ecological environment worsens sharply and harmful substances remained in agricultural products increase constantly, thus impair agricultural product quality and the improvements of its benefit, restricting the sustainable development of ecological agriculture too

    目前，我國農業發展面臨著資源、需求和環境約束。一方面，農產品供給已由短缺轉向總量基本平衡，我國加入wto后，農產品又將面臨激烈的國際市場競爭，市場需求對農業發展的約束力越來越大；另一方面，隨著化肥、農藥的大量使用，農業生態環境急劇惡化，農產品中殘留的有害物質不斷增加，影響了農產品質量和效益的提高，也制約著生態農業的可持續發展。
