近年,国内外对蔬菜无土栽培的实验研究工作日益深入和发展,共研究的范畴基本是围绕基质和营养液二大方面。就此二方面而言。营养液对于果实的产量和品质又占有至关重要的位置,选择适宜的营养液可以为作物的生长发育提供优良的营养条件和生理环境,取得最佳的产量结果和经济效益,起到事半功倍的作用。对于营养液的选配,微量元素固然是不可乎视的,但大量的起决定作用的仍然是N、P、K三要素。现代农业研究的结果告诉我们
In recent years, the domestic and international experiments on soilless culture of vegetables have been deepened and developed. The scope of the research is basically centered on two aspects of matrix and nutrient solution. In this regard, two aspects. Nutrient solution plays an important role in the yield and quality of fruit. Choosing the appropriate nutrient solution can provide excellent nutrition conditions and physiological environment for crop growth and development, and achieve the best yield results and economic benefits with a multiplier effect effect. For nutrient solution matching, trace elements are of course beyond view, but a large number of decisive factors are still N, P, K three elements. The results of modern agricultural research tell us
