In 1962 and 1963,the development of tillers,leaves and spikes of the winter wheat,varietyNung-ta 183,under the conditions of different planting dates were observed at Tai-ku,Shansi.Their relationships were recorded and summarized briefly as follows:1.The total number of nodes of each main culm is approximately the same as that ofthe leaves of the same culm.In a definite variety of wheat,the number of underground nodesof the main culm can be calculated through the following relations:Number of underground nodes of the main culm=Number of leaves—5(nodes aboveground)—1(Bud sheath node).Not all the underground nodes form tillers.Empty-tiller nodes often appeared to be effect-ed by different temperatures.Although the number of underground nodes of Nung-ta 183 isusually six or seven,yet the tillers developed are from one to five or six only.Generally,thesixth or seventh node does not produce tillers.2.According to the order of development of the main culm and the first lateral tillers aswell as the ratio between them,three different types of tillering can be classified.It is noticedthat all the three types developed two larger tillers firstly from the main culm.This is ofimportance in controlling the rate of heading of tillers in wheat production.3.It is also found that when the planting date is at its optimum,the culms of the wheatpopulation are mostly composed of the tillers from the main culms and those of the first laterals.If the planting date is earlier than optimum,tillers from the secondary laterals appear in con-siderable amount.From all these,it seems that the importance of tillers to wheat yield isof no subordinate to the main culms.In case of late planting,when the seedlings do notemerge before winter,a considerable amount of effective tillers are also formed in the nextspring.It seems doubtful to consider that the tillers developed before winter are effectivewhile those which developed in the next spring are ineffective.4.The tillers from the first laterals,whether headed or not,are of great importance toprovide a maximum surface for photosynthesis.They serve as an agent in making the bestuse of the environment so as to help the development of the heads of the main culm and thefirst laterals.5.Within the population,the amount of the tillers developed from the main culm variesfrom 54% to 64%.The dry weight of the first two tillers of the main culm,as well as theeconomic characters of their spikes,are closely correlated with those of the main culm.Ashas been shown,therefore,field management should be carried out in such a way as to stimulatethe growth of the main culm,its first two tillers and tillers from the first laterals.Othertillers should be strictly prevented from existing.6.In plants of different planting dates,it is observed that the variations of the totalnumber of leaves per plant are due mainly to the variation of the number of underground nodeleaves.The amount of the underground node leaves is directly related to the duration of tillering as well as the number of tillers produced from each main culm.7.The dates of emergence of different leaves from a tiller correspond orderly withthat which emerged from the main culm.It is shown that,the number of total leaves per plantis highly correlated with that of the main culm(r>0.94).Emperical formula is devised incalculating the number of leaves of any tiller by the number of l(?)aves in its main culm.8.Before heading stage,new leaves develop continually,while old ones become wilt anddead by and by.As a result,the total number of the working leaves per stem maintains 3-5only at different stages.Observed data prevailed that headed tillers should have more thanseven leaves with their total working days up to 300 at least.Most of the unheaded deadtillers develop less than four leaves with 50-150 total working days.9.The date of the appearing of each tiller corresponds with that of a definite leaf fromthe main culm.The magnitude of correspondence varies with different laterals.So that thenumber of responsible tillers to each leaf increases according to the increas

根据1962及1963两年,对于冬小麦农大183,在不同播期条件下,分蘖、叶片及穗部等性状的观察资料,分析了主茎、分蘖、叶片及穗部之间的关系;论述了分蘖或在组成小麦群体中的地位;各级分蘖成穗率及其经济性状的比较;叶片的功能期;叶龄与分蘖力的关系;主穗与分蘖穗在穗分化上的差异;穗群分化及叶龄指数和叶龄余数与穗分化的关系。文中还初步提出了根据主茎叶片数目,推算分蘖节数目、分蘖叶片数目及单株分蘖力的经验公式。

Deep plowing and adding of organic fertilizers to improve soil fertility are the foundations of high and stable yield for wheat.In a highly fertilized soil,seeds may be sown at a reasonably early date.In so doing a good growth of individual plants, a uniform population with a good canopy,and a quite high rate of effective tillers can be expected. In our experiments we have adopted the following cultural routine: (a)A good choice of high yielding variety(our choice is A.U.139). (b)A reasonable early date of sowing....

Deep plowing and adding of organic fertilizers to improve soil fertility are the foundations of high and stable yield for wheat.In a highly fertilized soil,seeds may be sown at a reasonably early date.In so doing a good growth of individual plants, a uniform population with a good canopy,and a quite high rate of effective tillers can be expected. In our experiments we have adopted the following cultural routine: (a)A good choice of high yielding variety(our choice is A.U.139). (b)A reasonable early date of sowing. (c)A sowing of 100,000 seedlings per mu(666.6 m~2). (d)A total of 700,000 tillers per mu before over-wintering(about 1.2 times the number of heads per mu)and more than 1,200,000 tillers per mu after winter- ing(about twice the number of heads per mu). (e)Finally,a total of 550,000—600,000 heads per mu when ripe.(There will be more than 26 grains per head,a 1,000 grains will weigh 36 g or higher,and the yield will be more than 500 kg per mu). In the district of Peking where winter wheat is usually sown in the autumn, the most important factor for high productivity is the rational control of spring tillering so as to achieve a good canopy.When Wheat land is highly fertilized and its moisture condition is good,the final watering(during the stage of grain filling) is applied about 20 days prior to maturity.A reasonable control of soil fertility (mainly available soil N)by proper management of irrigation is a profitable means to regulate the N-C metabolism to attain a higher weight of 1,000 grains.

深耕、增施有机肥料培养地力,是夺取小麦高产稳产的基础。在肥沃地上适期精量播种,在保证个体良好发展的前提下,协调群体的发展,提高分蘖成穗率,是夺取高产的关键。适期播种的农大139品种,每亩10万苗左右,越冬前总茎数每亩70万左右,越冬后最高总茎数控制在每亩120万以内,每亩55—60万穗,每穗26粒以上,千粒重36克以上,即可获得每亩千斤左右的产量。在北京地区冬性品种,关键是控制好春季分蘖才能达到合理群体。肥足墒好的地块,灌浆水适当提早到成熟前20天左右,以水控肥(氮肥),有利于调整碳氮代谢,提高千粒重,夺取高产。

“233”,a high-yielding semidwarf hsien rice(Oryza saliva,subsp. indica)early variety,which had been bred by Fujian agricultural college, was developed by crossing Zhen-long 410 with Colan-bologo.from 1975- 1978.It was planted about 15000 hectares in Fujian province in 1981.It's yield about 6000kg./ha.while it may yield as high as 9000kg./ha.under favorable condition. The experiments indicated“233”was a 110-125 days growth duration variety,and made it suitable for double-cropping.Temperature is one of the major factors affecting“233”growth duration.and the effective temp- erature summation for“233”growth duration.is 1450±21.8°C. When 4th,5th,6th,and 7th.leaves were cut off,the number of tillers reduced.And the number of panicles decreased,if the 8th,9th,10th,11th. and 12th.leaves were out off.Kernels per panicle decreased when 8th and 9th.leaves were cut off.Furthermore.the rate of filled grains was much less then the control,when the 10th.11th,andl2th,leaves were cut off. Most primary tillers of“233”grow out from 4th,5th,and 6th.nodes of the main culm and give rise to secondary tillers,within 8-15 days after transplantation. During the panicle development stage,the panicle continues to develop slowly,when it has grown to a length of 5cm.The grains per panicle are determined by the number of branches and spikelet primordia differentiated. The number of primary branches was more than the number of secondary branches in high yield(7500-9000)kg./ha.,and while the yield of 4500 7500kg./ha.,secondary branches were more than primary branches.

早籼“233”是福建农学院遗传育种教研组用珍龙410与石轮棒杂交、回交,于1978年育成的。1981年全省推广30万亩,亩产可达1200斤,一般700~900斤。1981年早季采用不同时期剪叶处理,探讨不同叶层与产量构成因素的关系。观察分蘖特性、幼穗发育。乳熟期采用去叶、去穗处理探讨主茎与分薛养分的运转关系。并进行大面积生产调查。所有材料分别进行方差分析、新极差测验。主要结果如下:1.“233”全生育期110~125天,12—13叶,有效积温1450±21.8℃。稻米粗旦白质含量11.049%,16种氨基酸含量90.93/毫克。2.剪除4—7/0叶影响分蘖数。剪除8~12/0叶影响分蘖成穗率。剪除10-12/0叶削减茎秆单位长度干重、穗粒数和粒重。3.“233”多数分蘖着生于4/0、5/0、6/0三节位。主穗与分蘖穗的养分供应有相对独立性。但分蘖叶提供主穗的同化物多于主茎叶供应分蘖穗。
