This work was conducted in 1955-1956 at Nanking (32°03'N'),China.800 rice varietiesnative to China were collected and sowed under the day-length of 9.5,11.5,12.5,13.5,and 18hrs.and natural day-length as control.Bamboo frames with black oil-cloth were used to shutoff day-light for short-day treatments.While electric lamps were used to lengthen naturalday-length for long-day treatments.Seeds soaked with water for 36 hours and vernalized at25℃ for 12 days and then,sowed on May 20:It was demonstrated that even under...

This work was conducted in 1955-1956 at Nanking (32°03'N'),China.800 rice varietiesnative to China were collected and sowed under the day-length of 9.5,11.5,12.5,13.5,and 18hrs.and natural day-length as control.Bamboo frames with black oil-cloth were used to shutoff day-light for short-day treatments.While electric lamps were used to lengthen naturalday-length for long-day treatments.Seeds soaked with water for 36 hours and vernalized at25℃ for 12 days and then,sowed on May 20:It was demonstrated that even under warm and proper short-day conditions—commonly9,5 to 11.5 hours of exposure to light for 24 hrs.cycle—the length of growth periods (fromsowing to heading) for different rice varieties varied from 42 (The shortest one Changjidao,a native variety of changji,Xinjiang) to 88 days (The longest one,Hongzuijia,a nativevariety of Fenghua,Zhejiang).This characteristics of rice varieties was denoted by the term“short-day growth period”.According to length of growth period under short-day conditionwe divided the rice varieties into 10 classes as follows:The rice varieties were thus classified and the result was listed'in table 1.It shows thatthe rice varieties from South China varies from B_1 to B_(10);the Middle and South-western Chinavarieties,from B_2 to B_9;the North China varieties,from B_2 to B_7;the North-eastern Chinavarieties,from B_2 to B_6,and the North-western China varieties,from B_1 to B_3.This resultstrongly indicates that the property of “short-day growth period”of a rice variety is closelyrelated to the climatic conditions of its original habitat.In regions of high latitude or plateauwith high altitude,usually accompanied with shorter growing season,the rice varieties withshorter length of growth period would be suitable for cultivation;while in plains of lowlatitude,usually followed by longer growing season,the rice varieties with either shorter orlonger length of growth period might be recommended for use.The earliness of maturity of a rice variety is fully determined by its “short-day growthperiod”and response to day-length.Thus we had in Nanking: L,response to day-length;B,“short-day growth period”.The yield components,especially the number of spikelets per panicle varied greatly amongthe rice varieties of different response to day-length under the conditions of experimentaltreatments.The data show that for very weak response type of rice varieties,the averagenumber of spikelets per panicle varied from 9.5% to 105% (take average number of spikeletsper panicle under 11.5 hrs.of light exposure in 24 hrs.cycles as 100%) under the testedrange of day-length;for weak type 90%-120%;for moderate type 0-124%;for strong type0-218%;and for very strong type 0-150%.Thus,it is evident that the stronger the varietyresponds to day-length,the greater,the variations of the number of spikelets per panicle wouldbe.This was further confirmed by the evidence that rice varieties of L very weak andL weak types always show greater ability of adaptation to changed conditions.Hence,moreattention should be paid to rice varieties of these two types for specialists of seed improve-ment.It should be emphasized especially for seed improvement of subsp.Keng,because onlya few varieties now existed are of L very weak and L weak types with medium “short-daygrowth period”.Such types of rice varieties are urgently needed in present crop-production.

用800个中国水稻品种试验的结果指出:不同地区原产的品种不但对光照长度的反应特性不同,而且在短日照下的生育期也不同。这种特性称为短日生育性。北方的品种短日生育性较小;南方的品种从小到大都有。品种成熟期的早晚是其光照长度反应特性和短日生育性在一定环境条件下的具体表现,改变环境条件时,早晚熟的顺序随之改变。对光照长度反应弱的品种一般产量变化小,适应力大。试验结果得出各地区品种的光长反应特性和短日生育性。

Correlation analysis, analysis of covariance and partial regression equation analysis were used to evaluate the data obtained on 197 plots of paddy fields of maximum yield in order to clarify the yield components and the dynamic structures of rice population. The grain yields of these fields in 1978 and 1979 were all higher than 8250 kg/ha per crop. The results were summarized as follows: 1.

Correlation analysis, analysis of covariance and partial regression equation analysis were used to evaluate the data obtained on 197 plots of paddy fields of maximum yield in order to clarify the yield components and the dynamic structures of rice population. The grain yields of these fields in 1978 and 1979 were all higher than 8250 kg/ha per crop. The results were summarized as follows: 1. Results obtained in both hybrids "Shan-you 2" and "Si-you 2" of the first or second crop under the multiple crop system indicated that the partial correlaton between the yield and the sum total of grains and between the yield and the percentage of ripe grains was significant. The values of the partial correlaton coefficient between the sum total of grains and the percentage of ripe grains and between the sum total of grains and 1000 grain weight showed negative significance. However, positive correlations between the sum total of grains and total full-grains were highly significant. Therefore, following the increasing of the sum total of grains, both hybrids gave increased yields, although the percentage of ripe grain and the weight of grain appeared somewhat being reduced. 2. The sum total of grains depended upon the number of available panicles multiplied by the basic numbers of grains per paaicle. 3. Significant positive correlation was found between the number of existed basic seedlings and the sum total of grains. In other words, with 15-120 thousand existed basic seedlings, the more the number of basic seedlings existed, the more the effective panicles were obtained and the more the available grain numbers. 4. According to the data obtained in this study, the number of seedlings to tillers and panicles inductive to high yield strcture is in the ratio of 1:3:2. Both hybrids "Shan-you 2" and "Si-you 2" had 20 million and 31 million grainsrespectively, producing 1050 kg. per hectare per crop.

本文用相关分析、协方差分析和偏回归方程分析的方法,分析了福建水稻高产区——龙溪地区1978、1979两年杂交水稻亩产1100斤以上的197块高产田的产量构成因素和群体动态结构,结果如下: 1、汕优2号、四优2号早、晚季都表现产量与总粒数、产量与结实率的偏相关达显著水准。总粒数与结实率、总粒数与千粒重之间成极显著的负偏相关。但总粒数与总实粒数成极显著的正相关,因此,增加总粒数,即使结实率和粒重有所下降仍然增产。 2、增加总粒数是在一定穗粒数的基础上,通过增加有效穗来达到。 3、汕优2号、四优2号的有效穗与总粒数成极显著正相关,基本苗数与有效穗数的关系也非常密切,即亩基本苗在1.5—12万范围内,基本苗愈多,有效穗愈多,总粒数愈多。 4、高产田群体的动态结构是按1:3:2的苗、株、穗比例,亩产1400斤的总粒数为2900万(汕优2号)与3100万(四优2号)。

1. The experiment was carried out at a people′s commune in north Jiangsu.Medium indiea rice "76—01" was planted and yielded an average of 551.9 kg per mu (8.3 Tons/ha) on an area of 142.83 mu (9.52 ha). An analysis of the results obtained indicated that for this rice variety, a total number of 27 million spikelets per mu was needed to produce a yield of 550—600 kg of grains(8.25-9 Tons/ha).The yield components should be: 210—240 thousand panicles per mu;more than 120 grains per panicle; about...

1. The experiment was carried out at a people′s commune in north Jiangsu.Medium indiea rice "76—01" was planted and yielded an average of 551.9 kg per mu (8.3 Tons/ha) on an area of 142.83 mu (9.52 ha). An analysis of the results obtained indicated that for this rice variety, a total number of 27 million spikelets per mu was needed to produce a yield of 550—600 kg of grains(8.25-9 Tons/ha).The yield components should be: 210—240 thousand panicles per mu;more than 120 grains per panicle; about 90% ripened grains and 25—26 grams per 1,000 grains.2. The dynamic state of population development for the rice variety"76-01" to yield 550—600 kg per mu was found to be-early emergence and steady growth of the tillers; steady growth at the elongation stage with light-green and thick erect leaves which should not be senescent early before maturity. Over 210 thousand tillers were expected 20 days after transplanting on the basis of 80—120 thousand seedlings planted per mu. The maximum number of tillers appearing 30 days after transplanting should be controlled at a level of 350—400 thousand per mu. The leaf-area-index (LAI) at the heading stage should be 7.3. The length of the last three leaves counted from top downward should be 25—28 cm,41—45 cm and 45—50 cm respectively.3. Under medium fertility of soil, 16—18 kg of nitrogen, combined with an adequate amount of P_2 O_5 and K_2O were required to produce a promising yield of 550—600 kg per mu. Among them 50—60% should be allocated to basal dressing, 30—40% to the tillering stage and 10% to the stage just before reduction division.4. An analysis of the economic effect of the high-yielding cultivation on an area of over 100 mu showed that in spite of higher production cost, greater output value, lower cost per unit product and higher net income resulted. The net income of the high-yielding fields exceeded that of the general ones by 37.39 yuan per mu.
