Of 9 experiments made on the planting rate of corn in 1958 to 1962,5 were subjected tothe combination with different arrangements.The relation of planting rate to biological yield,grain yield,as well as the other 40 quantitative characters and field meteorological factorshave been studied.The effect of agrotechnic levels and the amounts of manuring on theoptimum rate of planting has been investigated.The main results obtained are summarized asfollows:1.The relationship between planting rate and yields.(?)It has been found that therelation of planting rate to biological yield may be expressed by a modified hyperbola.Thegeneral formula is W=x/(a+bx).The asymtete is(?)=1/b.The relation of planting rate tograin yield may be expressed by parabola-like curve.The general formula is w=ae~(bx+lnx).,while the planting rate with the highest yield is x=(-1)/b.Furthermore,the yield-rate equa-tion composed of biological yield and the coefficient of economic yield has been analysed,andthe equation is listed as formula (7) in the article.2.The relation of planting rate to certain quantitative characters.(?)It has beenfound that from among 40 quantitative characters,32 may respectively be expressed by thefollowing formulae:(1) Y=x/(a+bx),(2)Y=1/(a+bx),(3)Y=ae~(bx),and (4) Y=a+bx.The relations of planting rate to the three quantitative characters (i.e.stages of growth anddevelopment,changes of leaf area and accumulation of dry matter) are unknown,but theirresults may clearly be described;the relations of planting rate to another five quantitativecharacters (i.e.length of plants and ears,percentage of grain production,volume weight andnumber of leaves per plant) have not yet been reached the conclusion.The changes of leafarea have fully been studied on five experiments,and based on the statistics of rate of growth,rate of fluctuation,and rate of declination,the plan for proper development of green leaf areato secure high yield has primarily been issued.3.The relationship between agrotechnic levels and the optimum rate of planting.(?)According to experiments,it has been indicated that the planting rate of corn may be increasedproperly so long as the levels of agrotechnics are raised.The equations for expressing therelationship between planting rate and the grain yield under different agrotechnic levels wereobtained and briefly discussed.4.The relationship between the amounts of manuring and the optimum rate of planting.(?)This relation is similar to that of 3,namely,the rate of planting may be increased aslong as the application of manure is increased.But the efficiency of manuring is diminishedaccordingly due to the increase of planting rate.5.The relationship between the planting rate and the field meteorological factors.(?)The record of the temperature and relative humidity for 24 hours showed that the changebetween day and night is lessened according to the increasing of planting rate.The light in-tensity above the ground surface of the population is reduced as a result of increased plantingrate,but the speed of such reduction is gradually lowered in proportion to the increase ofplanting rate.

The heterosis of hybrid rice was shown highly significant in yield,however,it was complicated in seed-production and too expensive.Se-parating tillercultivation in hybrid rice instead of seedling transplantingcultivation was an effective way for saving seeds.For getting multitil-lers of the hybrid rice,seeds should be sown one month earlier underadequate fertilizer and water condition.The proper time for tiller tran-splanting should be set at 13.0 of leaf age.Due to the efficiency ofhigh leaf position and the bigger leaf area as well as the longer leaf li-fe of each functional leaf(n,n-1,n-2,n-3 etc.),the tiller transplan-ted plant possessed with a stronger photosynthetic ability,high accumu-lation of dry matter and bigger panicles with multi-kernels resultingan increase of grain production.In 1979-1980,60 hectares of paddyfield in the suburb of Shanghai were under tiller-transplanted rice in-creasing the yield by 4-10%,7.2% in average,as compared with thoseby seedling transplanting.

杂交水稻优势明显,增产显著,但制种烦杂,成本高。采用剥蘖栽培的方法,能有效地节省用种量,剥蘖栽培比生产上的种子栽培早播一个月,通过繁殖田优越的肥水条件,使之充分分蘖,再剥蘖栽插,以蘖代苗,可节省用种。剥蘖栽培栽插时叶龄13.0,种子栽培为7.0,剥蘖栽培的群体叶层由较高叶位的叶片所组成,它具有“高叶位效应”,生育过程中,各工作叶片(n、n-1、n-2、n-3等)的长度、宽度、厚度和叶片寿命等,均较种子栽培的对应叶为优,因而叶面积大,光合势强,合成的干物质多,从而穗大粒多,具有增产作用。1979~1980年上海郊区试种900亩,比种子栽培增产4~10%,平均增产7.2%。

This paper provides a general analysis of the problems of agricul-tural production in Shaanxi-Gansu-Ningxia arid and semiarid areas basedon a bulk of inventoried information. To begin with, it was pointed inthis paper that scantiness of rainfall and complicated natural conditionsconstitute the very great constraints to agricultural production-foodproduction in particular, while both forestry and livestock productionis much more stable than agricultural production. The recovery of vege-tation, control of water and soil erosion and rational land use can onlybe achieved by gradually changing the present land use types of takinggrain production as the major undertaking, increasing the ratio of fore-stry and livestock production and taking an all-round way to developagriculture, forestry and livestock in order to enhance the advancementof rural economy in these areas. In this process, it is highly importantto deal with the ratio relationships among different kinds of under-takings. In view of this, this paper further presents the following impor-tant measures to be taken:1. Grain production should be served as the foundation and basiclink to stimulate an all-round development of agriculture while payingattention to the development of forestry and livestock. It is unrealistic tolet peasants make large amount of irrational use of land restored toplantation for growing trees and grasses because the food problem cannot be well solved.2. The solution of the food problem should start from the localexisting conditions Such as serious dryness, shortage of water and waterand soil erosion, and hence, rainfed farming should be extended in abig way, including building drought-resistant and harvest-ensuring basicfarm lands, drought resistant tillage methods, breeding drought-resistantcrop strains and changing the wasted fallow practice into that of grassfallow, etc. 3. Pursuing an effective policy and making rational use of nationalaid funds: for example, to change the "aids with the pure release fund"into the supporting aids with a production nature; to determine the ratio-nal direction for investment and to carry out a rewarding and tech-nical policy.4. Effective measures should be taken to control the growth of po-pulation in these areas, wbich is an unneglected and important aspectin an allround development of agriculture.Despite a large number of constraints to the development of agricul-ture in these areas, it holds a great potential for developing agriculture,forestry and animal husbandry because of vast land areas, abundantheat-energy resources and 300-400 mm of precipitation in most areas.As long as people do everything according to natural laws, the back-wardness of agricultural production in these areas will be bound to bechanged as quickly as possible starting from the local conditions andnatural features and seriously carrying out some policy and relatedmeasures.

本文根据大量调查材料,对陕甘宁干旱半干旱地区的农业生产问题作了概括性的分析。首先指出本区雨量稀少、自然条件复杂,对农业(粮食)生产的限制性很大,而林业和畜牧业要比农业生产稳得多。逐步改变目前以粮食为主的土地利用方式,增加林牧业的比重,走农、林、牧全面发展的道路,才能恢复植被,控制水土流失,合理利用土地,促进本地区农业经济的发展。而在此过程中,正确解决各业之间的比例关系尤为重要。由此观点出发,进一步提出了下列几项重要措施: 1、在重视发展林牧业的同时,应把发展粮食生产作为推动农业全面发展的基础和基本环节。因为吃饭问题不解决,要农民将大量利用不合理的土地退耕下来造林种草,是不现实的。 2、解决粮食问题,要从本地区干旱缺水、水土流失严重的特点出发,大力推广旱作农业,包括修建抗旱保收的基本农田,抗旱耕作法,培育抗旱作物品种以及改撩荒耕作为草田轮作等内容。 3、推行有效政策措施,合理利用国家援助资金,如改“单纯救济”性的援助为生产性的资助,确定合理的投资方向以及执行有关奖励政策和技术政策等。 4、采取有效措施,切实控制本区人口增长速度,这是全面发展本区农业生产不可忽视的重要方面。 本地区发展农业的限制因素虽然较多,但这...
