矮化型核桃新品種岱香的選育研究This is mainly due to the improvement of rice varieties, including ( 1 ) the development of semidwarf rice varieties suitable for mechanical harvesting, ( 2 ) the development of varieties resistant to lodging resulting from heavy fertilizer applications, ( 3 ) the development of varieties resistant to diseases and insects, ( 4 ) the establishment of a good seed propagation system, and ( 5 ) the rapid renewal of rice varieties through the services of the rice nursery centres
主要是改善了水稻品種，這包括： 1 ）選育半矮化品種，有利於機械收割； 2 ）選育抗倒伏品種以適應高施肥量； 3 ）選育抗病蟲害的品種； 4 ）建立良種繁殖基地； 5 ）通過水稻育苗服務中心，及時更新品種。Excellence breeding technology and system have been built using dwarfing - sterile wheat and recurrent selection technology for longterm study and trying, and important progress have made in variety breeding, germplasm creation, transfer of characteristic inherit of dwarf male - sterile wheat and physiology bio - chemical etc
矮敗小麥育成后，經過中國農科院等科研單位多年的研究與摸索，逐步建立起一套科學、方便、實用的矮敗小麥輪回選擇技術體系，並在品種選育、種質創新、矮敗小麥遺傳特性轉移、生理生化等方面取得了很大的進展。Then, by the comprehensive analysis of essential conditions for stone forest development, and the quantitative study on the evolution phases of bajiang karst catchment and the spacial coupling analysis of its hydro - geomorphological system, the paper studies the relationship between the evolution of bajiang karst drainage area and the development of stone forest, and, combined with the evolution history of the catchment, puts forward a model concerning the relationship between the evolution of bajiang karst catchment and stone forest development, in the mechanism of " tri - level erosion ", if a < s < c, the visible and actual height of stone pillars will keep on increasing, meanwhile, soil layer among stone pillars will become thicker and thicker, so the the height of stone pillars " root will become higher and higher, too
在「三重剝蝕」機制中，若a s c ，石柱的可見高度和實際高度會不斷增高，同時，石柱的根部的土層會增厚，其土下部分的高度也會不斷增大。若a c s ，說明石柱的實際高度在增加的同時，其可見高度也在增加，但土層會變得越來越薄，最終當底土被完全剝蝕掉后，氣下溶蝕和土下溶蝕的差異消失，此時a接近於c ，石柱的實際高度將停止拔高或極緩慢增長，並在各種物理、化學風化的作用下而變得日益矮小。若s a c ，石柱的可見高度將趨于變矮，但驅動石林發育的土層厚度將會增大。On the other hand, maize dwarf mosaic ( mdm ) is a kind of main disease that cause huge drop in production and there is no effective pesticide now. antisense rna of maize dwarf mosaic virus coat protein ( mdmv - cp ) gene can well depress the assemble of coat protein, avoiding mdmv disease effectively
玉米矮花葉病是造成玉米減產的一種重要病毒病害，目前尚無有效的化學藥物加以防治，而利用反義rna技術培育抗玉米矮花葉病的轉基因玉米是一條防治玉米矮花葉病害的經濟、有效的途徑。分享友人
