~(15)N labelled technique was used for understanding the transferring and cycling of nitrogen in micro-agroecosystems with soil-ryegrass-rabbits-rice compartments and soil rice compartments. Preliminary results showed that the utilizational rate of (NH_4)_2SO_4 by ryegrass was 59.36% for the above ground portion and 9.79% for roots. As ~(15)N labelled ryegrass was comsumed by rabbit,the ~(15)N labelled recovery rates in feces and urine collected were 11.78% and 17.95% respectively. Rabbit excrement-nitrogen...

~(15)N labelled technique was used for understanding the transferring and cycling of nitrogen in micro-agroecosystems with soil-ryegrass-rabbits-rice compartments and soil rice compartments. Preliminary results showed that the utilizational rate of (NH_4)_2SO_4 by ryegrass was 59.36% for the above ground portion and 9.79% for roots. As ~(15)N labelled ryegrass was comsumed by rabbit,the ~(15)N labelled recovery rates in feces and urine collected were 11.78% and 17.95% respectively. Rabbit excrement-nitrogen was integrated with inorganic fertilizer nitrogen in different proportions as 1:0, 0.5:0.5, 0.3:0.7 and 0:1 for rice culture. Results showed that the uptake of nitrogen by rice plant was 67—70% from the soil and 30—33% from fertilizers.The utilizational rates by rice plant were increased with the proportion of inorganic nitrogen. They were 36.94%, 40.52%, 40.73% and 43.91% for treatment 1—4. The yield of rice grain decreased with the proportion of inorganic nitrogen, however. The functional effects of organic fertilizer on the ecosystems were:(l) promoting the ear and root development of rice plant;(2) increasing the transferring ability of nitrogen from straw to rice grain, especially in 0.5:0.5; (3)maintaining inorganic fertilizer nitrogen in soil; (4)decreasing losses of nitrogen to air and waters. In treatment 0.3:0.7, the utilizational rate of organic fertilizer nitrogen was enhanced, and no considerable increment of utilizational rate of inorganic fertilizer nitrogen was found in the study. According to the complexity of food chain and the nitrogen recycling indexes in different microecosystems, it is considered that the maturity and stability of the ecosystem were higher in treatments 1:0,0.5:0.5, and 0.3:0.7, but lower in the treatment 0:1 which consists of rice plantation and relaying on inorganic fertilizers only.

本文应用~(15)N示踪法研究了有机态和无机态肥料氮在微型农业生态系统中循环的机理,以及配施下各自的功能和相互影响。初步结果表明,在土壤-黑麦草-兔亚系统中,草对硫铵~(15)N利用率达59.36%;以草饲兔,所收集兔粪~(15)N回收率为11.78%,尿为17.98%。兔粪尿N与硫铵N以1:0,0.5:0.5,0.3:0.7和0.1配施种稻,结果表明,在土壤-水稻亚系统中:(1)0.5:0.5配施促进穗头和根系发育;(2)稻株吸收有机态和无机态肥料N的比例,受配施比例的影响;(3)与单施无机肥料氮比较,配施下无机肥料氮利用率未提高或甚至下降;(4)0.3:0.7配比使有机态肥料N利用率提高;(5)0.5:0.5配比,有机肥能明显地促进无机态肥料N从秆向谷运输;(6)有机肥使无机态肥N在土壤中的固化作用增加,从而使无机肥料氮向环境转移量下降。农业生态系统具有多组分和牧食-碎屑复合食物链,氮素再循环指数达0.5,生态稳定性和发育程度优于单一种植系统。

The fertilization systems adopted in different stages of agricultural development of China influenced significantly the productivity of farmlands. Results of experiments conducted for simulating the different fertilization systems in fields at the Ecological Experiment Station of Red Soil of Chinese Academy of Sciences showed that the rice yields of different treatments were that residue return (as 100%) < N + residue return (109%) < NPK (127%) < NPK + residue return (151%).

The fertilization systems adopted in different stages of agricultural development of China influenced significantly the productivity of farmlands. Results of experiments conducted for simulating the different fertilization systems in fields at the Ecological Experiment Station of Red Soil of Chinese Academy of Sciences showed that the rice yields of different treatments were that residue return (as 100%) < N + residue return (109%) < NPK (127%) < NPK + residue return (151%). The application of phosphate fertilizer combined with crop residues could promote the nutrient uptake by crop and nutrient transfer to the grains. The return of crop residues to soil could increase significantly the input of organic carbon and nutrient with a greater amount of soil organic matter formed than that mineralized and a distinct profit of soil nutrient element, ameliorate the cycling and balance of soil nutrients, accelerate the accumulation of soil organic matter. The treatments of single inorganic fertilizer have a little accumulation of soil nitrogen and a unstable balance. The cooperation of phosphate fertilizer and organic manure is very important for the restoration and improvement of soil phosphorus pools, the continuous application of crop residues could increase the soil available phosphorus. The crop straw, with a high content of potassium, is the important resource of soil potassium in red soil region. The application of crop residues could increase the content of soil organic matter by 4 ~ 10 g/kg within 3 years, improve obviously the content of hydrolysable N, available P and K, enhance the coarse soil microaggregate. Therefore, increasing the return of organic materials to farmland and optimizing fertilization pattern with organic inorganic cooperation is the direction for the reform of fertilization systems in sustainable agriculture.

田间模拟不同农业施肥制度的试验结果表明,各处理水稻产量的变化趋势是循环(100%)<N+循环(109%)<NPK(127%)<NPK+循环(151%)。施磷肥以及在此基础上有机物质还田,提高了营养元素的吸收量及在籽粒中的分配比例。有机物质循环再利用,可明显增加系统有机碳的进入量及养分回田总量,提高系统物质循环水平;土壤有机质形成量大于矿化量,营养元素的盈余比较明显,养分库的平衡状况得到改善,有机质的积累速度加快。单施无机肥料,氮素的积累较少,基本平衡不稳定。磷肥和有机肥的配合施用对于红壤磷库的恢复和提高非常重要,作物秸秆的连续长期施用可提高土壤有效磷水平。作物秸秆的含钾量较高,回田秸秆是红壤区重要的钾素资源,对于恢复和提高红壤钾库有明显作用。有机物质循环再利用,可在3年时间内,提高土壤有机质含量4~10g/kg,碱解氮、速效磷、速效钾含量也有明显改善,较大粒级的土壤微团聚体含量增加。

An positioning experiment about improving way of straw mulching was conducted at the Ecological ExpermentalStation of Red Soil, Academia Sinica. Compared with the conventional way (surface mulching), muching with 5~10cm cover of sol could increase soil water content by 1 .5%, and decrease probability of occurrence of wilting moistureby 8% in drought season, thus improving the anti-drought effects. In addition, cmpared with control, deep ploughingcould increase the surface soil water content. The result of...

An positioning experiment about improving way of straw mulching was conducted at the Ecological ExpermentalStation of Red Soil, Academia Sinica. Compared with the conventional way (surface mulching), muching with 5~10cm cover of sol could increase soil water content by 1 .5%, and decrease probability of occurrence of wilting moistureby 8% in drought season, thus improving the anti-drought effects. In addition, cmpared with control, deep ploughingcould increase the surface soil water content. The result of experiment on different mulch materials showed that theapplication of ryegrass and peanut vine was superior to corn stover to the improvement of surface soil moisture, and theincrease in crop yields. It is suggested that corn stover serving as mulch materials should be cut into pieces andcompanied with the appation of inorganic fertilizers.

在中国科学院红壤生态实验站的猕猴桃园上进行秸秆覆盖改进方法的试验.结果表明,旱地红壤覆盖秸秆后再覆±5-10cm,与原来单纯覆盖秸秆相比,在干旱季节表层土壤水分含量可增加1.5%,凋萎含水量出现几率减少8%,抗旱效果大大增强,是一种值得推广的防旱措施.另外,与对照相比,深翻0.8m对改善土壤水分状况也有明显效果.不同覆盖物的试验结果表明,覆盖草本植物残体,在改善表层土壤水分状况、提高作物产量上的效果优于覆盖秸秆植物残体,建议在应用诸如玉米等稿秆作物的秸秆进行覆盖时应进行切碎处理并适当配施无机肥料
