  rice ecological
Eight typical rice stations ranging in latitude, longitude, and elevation that are located in the main rice ecological zones of China are selected for impact assessment.
      
Grouping principles used wereDingying's taxonomic system, Cheng-Wang taxonomic system,Yunnan rice ecological zone, Yunnan administrative district, singlecharacter and completely random sampling without grouping.
      


66 rice varieties collected from the different parts of Guizhou were divided into two groups: the natural day-length (check group) and artifical day-length of 10 hours group. The results are as follows: The light sensitivity of rice was weak-midding (Ⅰ-Ⅵ). The temparature response was weak-middingstrong(Ⅲ-Ⅸ). The growth period of a short-day high tempar temparature was long. The results show that the relation between headingday and light sensitivity, growth period short-day with high temparature is obvious.

以66个贵州地方水稻品种为材料,进行自然日照和人工短日处理的结果:水稻品种感光性弱一中,感温性弱、中、强均有,短日高温生育期长。由于贵州低纬度高海拔的地理因素,稻作垂直分布显著,水稻生态类型多种,加上种植季节不同,水稻光温反应型差异大。水稻出穗日数与感光性、短日高温生育期相关性显著。

hThe ecologcal conditions, physical and chemical properties of the mashed paddy soils in mountainous areas can be improved by adopting ridge culture, and then the soil fertility can be raised. Our experimental results in resent years showed that in the mashed paddy field adopting ridge culture, the water temperature was 1 ℃ higher and the mud temperature 0.3-1 ℃ higher than those of the conventional culture. Under ridge culture, the soil. became loose, the volume weight of the soil decreased, the soil aggregate got increased significantly the soil aeration and permeabitity got improved, the activity of soil microorganism got promoted, and then the conditions of water, nutrients, air. and heat in paddy soils got harmonized. Therefore, the rice plant got promoted to grow luxuriantly available ear number, grain number per ear and 1000-grains weight got increased. In general, fhe grain yield of rice increased by 11.5%-78%, comparing with the conventional culture. In some cases, the output raised double. These illustrated that ridge culture is an effective measure to improve the mashed paddy soils and to raise the gutput of rice.

在山区冷烂锈田实行水稻垄作,能改善水稻生态条件,改良土壤理化性状,提高土壤肥力。经几年试验,垄作比平作田水温提高1℃,泥温提高0.3~1℃;垄作后土壤变疏松,容重降低,<5mm团聚体明显增加,改善了土壤通透性,促进微生物活动,协调了土壤水、肥、气、热状况,从而促进水稻早生快发,有效穗和穗粒数增多,增加千粒重、提高水稻单产。垄作水稻产量一般较平作增高11.5~78%,有的成倍增长。说明垄作是改良山区冷烂锈田、促进水稻增产的一大有效措施。

The main components of the rice leaf roller—rice plant ecosystem are rice plant, rice leaf roller, natural ecemies, weather and managment measures, According to the analysis of the ecosystem components, 6 models were developed: Leslie matrix model of pest population, development rate model, oviposition model, prediction model of plant development, loss model of productivity, and simulation model of daily temperature, The simulation was made and the results showed that the ecosystem was sensitive to the adult,...

The main components of the rice leaf roller—rice plant ecosystem are rice plant, rice leaf roller, natural ecemies, weather and managment measures, According to the analysis of the ecosystem components, 6 models were developed: Leslie matrix model of pest population, development rate model, oviposition model, prediction model of plant development, loss model of productivity, and simulation model of daily temperature, The simulation was made and the results showed that the ecosystem was sensitive to the adult, the 5th instar larvae, the predators and the extreme weather condition.Chemical measures could suppress the pest population, but the density of next generation would increse adversely.The simulation results basically fits what occurred in the field.

稻纵卷叶螟—水稻生态系统包括如下成份:卷叶螟,水稻,自然天敌,天气,管理措施。根据系统成份的分析,建立了该系统的模拟模型,包括:卷叶螟Leslie矩阵模型,发育率模型、产卵模型,水稻生长发育预测模型,叶面积及产量损失模型,日温度变化模拟模型。系统模拟结果表明:系统对成虫期和5龄幼虫期比较敏感.捕食天敌和极端天气对系统影响很大,采用化学防治措施虽然可以降照当代虫口密度,但下代种群数量反而增加。系统验证结果基本符合田间实际情况.
