本文簡要的闡述了种稻改良盐碱地在我国盐碱地改良工作以及国民經济上的重要意义。种稻是利用盐碱地,特别是低洼盐碱地的最好方法。水稻的生理特性,正可以把低洼地区容易积水、两季易涝、盐分脫除困难等不利因素变成有利条件,不需要庞大的投資,当年就可获得300~400斤以上的亩产量。种稻由于用水期长、用水量大的特点,对于改良任何一种盐碱土,它起到的脱盐作用均較其他措施为大。并且还可通过灌溉水中大量的泥沙改善土壤理化性質。在改善水文地質条件方面也有明显的作用。本文着重指出了种稻改良盐碱地的关鍵措施——水利土壤改良技术的作用,特别对排水在改良盐碱地中的作用,作了比較詳尽的分析。对于种稻与碱土改良及种稻对周圍旱作地区的影响两个問題,也作了初步的探討。

Farming density has direct influence over the weight increase of individual fish and the colony yield. On the basis of practical production and experiments this paper sums up the rational farming dencity of silver carp fish in ponds in low-lying saline - alkali soil in Northern Henan Province.

在生产中,放养密度对鱼类个体增重倍数和群体产量有着直接影响,本文通过试验和生产实践,总结了豫北低洼盐碱地池塘鲢鱼的合理放养密度。

Samples of soils, pore water and pond water were taken from five ClNallwater-type ponds on saline-alkaline land. The contents of nitrogen and phosphorous in the soils, the pore water and the pond water have been determined. The four treatments were as follows: NaHCO3 4mmol/L plus soil-water mixture, CaCl22mmol/L plus soil-water mixture, NaHCO3 4mmol/L plus CaCl2 2mmol/L plus soilwater mixture, and simple soil-water mixture. Hence we could study the role of these treatments in increasing the ability of the bottom...

Samples of soils, pore water and pond water were taken from five ClNallwater-type ponds on saline-alkaline land. The contents of nitrogen and phosphorous in the soils, the pore water and the pond water have been determined. The four treatments were as follows: NaHCO3 4mmol/L plus soil-water mixture, CaCl22mmol/L plus soil-water mixture, NaHCO3 4mmol/L plus CaCl2 2mmol/L plus soilwater mixture, and simple soil-water mixture. Hence we could study the role of these treatments in increasing the ability of the bottom soils of brackish ponds to release nitrogen and phosphorous, and raising the availability of nitrogen and phosphorous. The result indicates that the four treatments have all made soils release NH4-H, PO4-P and have obviously reduced the concentrations of NO3-N and NO2-N in the water column, but the effects have not reached a significant level (P>0.05). Furthermore, the effects of these four treatments on the adsorption and desorption of four kinds of nutrients have no significant difference (P>0.05),which shows that the added NaHCO3 4mmol/L, CaCl2 2mmol/L and their mixture have not raised the availability of nitrogen and phosphorous significantly.Under these kinds of treating methods, the adsorption and desorption by bottom soils were affected by many factors, among which the contents of nitrogen and phosphorous in bottom soils are a main factor.

本文科用五个ClNaⅡ水型低洼盐碱地池塘的底泥和水样,测定了底泥、间隙水和池水中的N、P营养盐含量,并设定NaHCO34mmol/L加搅拌、CaCl22mmol/L加搅拌、NaHCO34mmol/L+CaCl22mmol/L加搅拌、搅拌等四种处理方法及对照,研究了四种处理方法对于促进盐碱池塘底泥营养盐的释放的作用。实验结果表明:四种处理方法都明显地促使底泥释放NH4-N、PO4-P,同时使水体中的NO3-N、NO2-N浓度减少,但都未达到显著程度(P>0.05),这说明加入的试剂并未显著增加盐碱池塘底泥营养盐的释放。在本实验的处理方法下,底泥对NH4-N、PO4-P的吸附与释放与底泥中NH4-N、PO4-P的含量有密切关系。
