矿物肥料的抗旱作用实践与机理的初步研究

APPLICATION OF REMOTE SENSING TO POTASH PROSPECTION IN LUOBUBO DISTRICT

光合作用是绿色植物通过叶绿体，利用光能的催化反应把二氧化碳和水合成储存能量的一种过程，特别是水在光合作用下，若不能与二氧化碳保持一定比例的平衡，则光合作用不能继续进行，势必影响到作物的产量。因此，若施用抗旱肥料，不仅光合作用得到新的平衡，更由于光照强度大，时间也长，使合成有机物的丰度大为改观。所以，作物若施用新肥，不仅抗旱，还能保产与增收。

Qualitative and quantitative analyses of potash mineralization in the Luobubo district by using an air remote sensing technique or processing the TM data/images, coupled with researcres on the Luobubo' s geological structures, indicates that the informations collected with the TM processing have a certain relationship to those picked up in analysing the potassium bend of gamma energy spectrum and the grade of potash mineralization. It comes from this relationship that the Luobufo potash mineralization be confined, temproally, to the Middle to Late Holocene and spatially, to the ring or earlike structures of the lake.
