我国稻作区的山坑湖洋田、冷湴田、深泥田、低洼渍水田等田类,地下水位高,水温地温低,速效养分少,供肥性能差,有毒物质聚集,水肥气热矛盾突出,严重影响水稻正常生长发育,产量低而不稳。我国土壤学家侯光炯教授应用土壤生物热力学理论,提出水稻半旱式栽培技术,以改善上述田类的土壤性质和环境条件,使水稻地下部分根系发达,地上部分生长健壮,以提高产量,开拓水稻平衡增产的新局面。1987年省农业厅生产处在我县华城、新桥
China’s paddy area of mountain pit lake fields, cold mound fields, deep mud fields, low-lying paddy fields and other fields, groundwater level is high, low ground water temperature, less available nutrients, poor performance for the fertilizer, toxic substances, water and fertilizer heat contradiction Prominent, seriously affect the normal growth and development of rice, low yield and instability. Prof. Hou Guangjiong, a soil scientist from China, put forward the semi-arid rice cultivation technology based on the theory of soil bio-thermodynamics, in order to improve the soil properties and environmental conditions of the above-mentioned fields, make the underground part of rice grow well and the aerial part grow robustly so as to increase the yield, Balance the new situation of production. 1987 Provincial Department of Agriculture Production Office in my county Hwaseong, Shimbashi
