  planting
The influence of woodland soil bulk density on the growth and distribution of fine root system of main planting tree species in the Weibei Loess Plateau was investigated by means of pot culture and field survey.
      
Besides, runoff and sediment produced in mixed planting of apple trees and crops were 16.14-fold and 2.96-fold than those of O.
      
Container stecklings are more likely to increase the planting survival rate.
      
Therefore, it is important to consider planting densities on the hillsides with slope gradients less than 10° for reconstructing vegetation.
      
To improve soil quality and maintain sustainable productivity, some measures, including planting mixed conifer with hardwood, preserving residues after harvest, and adopting scientific site preparation, should be taken.

  cropping
An experimental study on mitigation of greenhouse gas (CH4, N2O and NO) emission has been conducted in a typical cropping system of Southeast China for 4 years.
      
The experimental results show that this method can survive image cropping and image compression, and get better results, this is also a prospective method.
      
This technique produces a watermarked image that closely retains the quality of the original host image while concurrently surviving various image processing operations such as lowpass/highpass filtering, lossy JPEG compression, and cropping.
      
The actual watermark embedding in spatial domain is followed using permutated image for improving the resistance to image cropping.
      
A new site-specific nutrient management approach was developed to break the apparent attainable yield barrier of 6 t·ha-1 in the double rice cropping system of Zhejiang.

Agrarian lands can be divided into plantation landa and non-plantation lands. How to make a full and rational use of non-plantation lands is an important problem in agricultural land division, a satisfactory solution of which can help develop and modernize agriculture as a whole,Ba County has good hydrothermal conditions with a ready foundation for the utilization of non-plantation lands. A structure has been formed with forests and gardening woods as its core. The difference is also noticed in geographical division, which may follow the traditional method of classification or be calculated by means of quantitative analysis.on the basis of investigation, a suggestion has been put forward for the rational utilization of all the non-plantation lands in the county.Lands unfit for grains may be turned into non-plantation lands for oranges, tea or silkworms; lands with little or no woods may be used for forests; fish can be reared in paddy fields and whereever possible. This will help keep the ecological equivalence and make the countryside rich so as to speed up the modernization of agriculture.

农业用地可以划分为种植业用地和非种植业用地两大类。如何充分合理地利用非种植业用地,是农业现代化建设中搞好农业区划、发展大农业的一个重要问题。 巴县的水热条件优越,非种植业用地的利用已有基础,在利用上已形成以森林、园艺林地为主的非种植业用地结构,而且在地域分异上也存在着较为明显的差异。这种差异既可以用传统方法加以划分,也可以用数量分析方法进行计算,找出其地域差异。 为了充分合理地利用巴县的非种植业用地,在调查基础上,对全县非种植业用地的合理利用作了一个初步设想:将部分不适宜种植粮食作物的土地调整成为非种植业用地,发展适宜的柑桔、茶叶、桑蚕等;将疏林地、部分荒地用于植树造林;并充分利用可养殖水面和部分稻田发展养鱼。这样既可以有利于保持农业生态平衡,又有利于使全县农村尽快富起来,加快农业现代化建设的步伐。

Crop distribution is the main part of cropping system, Dependin on the methods of the line programing and grain/cotton ratio analysing,the reasonable ratio of grain crop to cotton was under taken, It was conclude that the improvement of cotton production bases on the increase in grain crop yield and removing ratio between grain crop and cotton area depends upon the increase in grain yield. It was suggested that, under present conditions,the proper percentage of cotton growing area should maintain about 35%....

Crop distribution is the main part of cropping system, Dependin on the methods of the line programing and grain/cotton ratio analysing,the reasonable ratio of grain crop to cotton was under taken, It was conclude that the improvement of cotton production bases on the increase in grain crop yield and removing ratio between grain crop and cotton area depends upon the increase in grain yield. It was suggested that, under present conditions,the proper percentage of cotton growing area should maintain about 35%. The main measures for raising the output of grain crop and cotton must improve the productive conditions, especially increasing the soil fertility and improying the farmland.

作物布局是种植制度的中心问题。本文通过典型生产单位,应用线性规划和粮棉比例关系分析的方法,研究了河北省衡水旱薄地区粮食作物和棉花的合理比例,得出该类地区棉花生产的提高,关键是提高粮食作物的产量,其种植比例应和粮食作物产量的增加相适应。在目前条件下棉花比例一般宜控制在35%左右。提高粮棉产量的基本措施是改善生产条件(主要是土壤肥力条件),建设基本农田,狠抓单产。

Agricultural cultivation in the northwest loess plateau has a long history. Owing to long-term irrational exploitation and utilization,the producttve structure tends to become monocultivation.The material circulation has been so seriously blocked that the raising of systematic productivity is confined. The fixed-position research in 1980 showed:“conversion efficiency between soil fertility and crop moisture is posittvely correlated with an obvious positive correlation.”and the results also deeply revealed that though dryness was a frequent threat to rainfed agricultural production on the plateau,poor soil fertility led to the waste of soil moisture,which was the direct cause for the low efficiency of utilization of plentiful of sunlight and heat resources. Research showed that perennial legume forage crop---alfalfa (M.satival)with an extensive ecological adaptibility ands tability should be largely planted in agricultural zones where there is lack of non-aiable land.pl- anting alfalfa must be taken as a break-through so as to regulate agricultural sturcture and intensify the integration of agriculture with animal husbandry. In this way,the bio-nitrogen fixed by alfalfa and other organic matter may be transferred into farmland through the channels of animal husbandry. And at the same time,the principle of enlarging material circulation chanoels of“lack of organic matter with compensation of ionrganic matter”should also be implemented.The close combination of the two was to prosper animal husbandry so as to promote agriculture and to change mnostructure and to setablish the stable agricultural production structurey related to natural resources on the plateau and with higherstable agrtcultural ecolgical effects and economi- cal returns.Every means possible should be tried to convert the potentialprod- uctivity into social wealth. In 1981,the sturctural reform testing points were set up in Guyuan/Chenchen /Yaoxian/Qishan counties with rainfall of 400/500/600 mm respectively. In these testing points,area of 10% or 20% of the arable land was devoted to plant alfalfa with the better results produced in 1983.The results revealed that rncressing planting alfalfa in the rainfed and irrigated regions with lack of non-arable land to stimulate agricultural sturcture refom was reasonable. The production returns of the first batches of testing points showed that planting alfalfa may have the following advantages;(1)enlarging material circulation channels to increase soil fertility;(2)lowering coefficient of soil moisture evaporation and raising of conversion efficiency of soil moisture and(3)edurcing consumption of farmland energy and raising energy conversion efficiency.

西北黄土高原农耕历史悠久,由于长期不合理的开发利用,生产结构趋于单一,物质循环障碍严重,制约着系统生产力的提高。一九八○年定位研究表明:“农田肥力与作物的水分转化效率呈正相关、相关显著”,深刻地揭示出,干旱固然是高原旱作农区生产的经常威胁,然而地力不足导致农田水分无谓地耗损,是丰足的光、热资源利用率低下的最为直接的原因。研究表明,高原非耕地欠缺的主要农区,扩种具有广泛生态适应性和稳定生产力的多年生豆科牧草——紫花苜蓿(M.SativL.),并以此为突破口,调正农业结构,强化农牧结合,使苜蓿所固定的生物氮连同有机质,通过畜牧业渠道集中地向衣田转移;同时实行“有机不足、无机补”的拓宽物质循环通道的原则,二者紧密结合应是兴牧促农,改变结构单一,建立与高原资源相适应的具有较高生态效益和经济效益的性能稳定的农业生产结构依据,尽可能地把资源潜在生产力转化为社会财富。一九八一年开始的,分别在年降水量400、500、600毫米地区的固原、澄城、耀县、岐山建立的结构改革试验点,以耕地10%或20%的面积种植苜蓿,一九八三年开始产生良好效果,正面显示出:在非耕地欠缺的旱作或灌溉农区,增种苜蓿促进农业结构改革是可行的。...
