It was shown by two-year observation of sainfoin pastures aged from one to nine years that with the development of saiufoin pasture in age the soil fertility and the amount of full-nutrients of nitrogen and phosphorus as well as the soil porosity and water-stable granules increased,while the soil density,specific gravity and compacness decreased, the result proved that sainfoin could play quite a good role in improving the physicochemical properties,raising soil fertility,making the amount of the soil nutrients...

It was shown by two-year observation of sainfoin pastures aged from one to nine years that with the development of saiufoin pasture in age the soil fertility and the amount of full-nutrients of nitrogen and phosphorus as well as the soil porosity and water-stable granules increased,while the soil density,specific gravity and compacness decreased, the result proved that sainfoin could play quite a good role in improving the physicochemical properties,raising soil fertility,making the amount of the soil nutrients reseve larger and turning nutrient supply for plants into a better condition,The optimum lengh for sainfoin pasture is about five years.

通过对1—9年生红豆草地的观测表明,随着红豆草生活年限的增长,土壤有机质及氮、磷全量养分逐年提高,土壤容重,比重和坚实度递减,而土壤孔隙度,水稳性团粒递增。显示出红豆草具有改善土壤理化性状,提高土壤肥力,增加土壤养分储量,增强养分供应强度的良好作用,但红豆草利用年限以五年为宜。

The main nutrition contents,enzymie activities,qualification of aquaous steady globs and salt accumulation in continuous cropping plastic greenhouse were investigaled. Results showed that the amount of main soil nutrients,the activities of soil urease,nutral phosphatase,acid phosphatase and 2~0.25mm aquaous steady globs increased,and the soil property of physical structure was improved. However,the chemical property of soil became worse and the salt was accumulated. 

采用面上调查和定点观测相结合的方法,分别对哈尔滨郊区不同连作(轮作)年限的大棚土壤的主要养分含量状况、酶活性、水稳性团粒分级及盐积状况进行研究分析。结果表明,随着连作年限的增加,土壤主要养分含量有增加的趋势,土壤脲酶活性、中性磷酸酶、酸性磷酸酶活性也有增加的趋势;2~0.25mm水稳性团粒增加,土壤物理结构性能有所改善;土壤化学性状变劣,出现了盐类积累。

By the combination of plot test and field development,and the system of two crops per year,wa- ter-saving and rain culture mode is discussed. The mode is covering with vertical remaining wheat stalk-corn seed sowing of no-tillage-chemical control-deep ploughing in seedling stage under present rotation cropping system of winter wheat-summer corn. This ploughing mode can reduce evaporation of soil by 3 %-3. 4% water and save about 50 % irrigating water,and can store 100-150 mm of natural rain. Soil volume weight...

The mode is covering with vertical remaining wheat stalk-corn seed sowing of no-tillage-chemical control-deep ploughing in seedling stage under present rotation cropping system of winter wheat-summer corn. This ploughing mode can reduce evaporation of soil by 3 %-3. 4% water and save about 50 % irrigating water,and can store 100-150 mm of natural rain. Soil volume weight of plough pan and below dropped significantly. Correspondingly, porosity and redox potential rats ed. And, water-stable crumb structure raised remarkably. It had obvious role of promoting desalting in saline alkali soil zone. Summer corn matures 7 d earlier and yield raises 10 %-30 % generally.

采取小区试验同大区开发相结合的方法,采用一年二作制,探讨冬小麦—夏玉米现行轮作体系下麦秸立茬覆盖一玉米免耕播种—化控—苗期深松节水雨养模式。该耕作模式能减少土壤水分蒸发 3~3.4个百分点,节省抗旱用水50 %左右,多蓄积自然降水 100~150 mm,犁底层及其以下层次的土壤容重明显降低、孔隙度相应增加、氧化还原电位相应提高,水稳性团粒结构明显增加,盐碱土地区具有明显的促进脱盐的作用,夏玉米一般提前成熟7d左右,增产幅度一般为10%~30%。
