To study the conditions required for the development in vernalization stage of peas and broad beans,a series of field experiments were carried out and the results are summarized as follows: Peas and broad beans were able to complete their vernalization stage of de- velopment under 0°—20° C.or even higher.Within the above mentioned temperature range,10°C.was more suitable than 0℃.;and apparently temperatures higher than 10℃.were even more suitable as indicated by the more rapid development...

To study the conditions required for the development in vernalization stage of peas and broad beans,a series of field experiments were carried out and the results are summarized as follows: Peas and broad beans were able to complete their vernalization stage of de- velopment under 0°—20° C.or even higher.Within the above mentioned temperature range,10°C.was more suitable than 0℃.;and apparently temperatures higher than 10℃.were even more suitable as indicated by the more rapid development under higher temperatures. When vernalization treatment was applied to the seeds in germinating condition the effect on hastening the emergence of flower bud was more significant when seeds were sown in June than when they were sown earlier;and the effect was also more significant with late varieties than with early varieties. When germinating seeds were treated at 0°—10℃.,the time necessary for the completion of vernalization stage was longer than 20—25 days.With seedlings unber field conditions the development in vernalization stage advanced more rapidly than with germinating seeds under artificial vernalization treatment.From spring to summer the time required for the completion of vernalization stage under field conditions shortened with the delaying of date of sowing. Based on the facts given above,it may be hypothesized that the effect of vernalization treatment on hastening the emergence of flower bud is determined by the relative length of the period required for the plant to complete its development in the vernalization stage after it has emerged from the soil as compared with the period required for the plant to accumulate those special nutritive substances indispensable for the development in photostage and the differentation of reproductive organs.

In this experiment,the cuttings of three varieties of sweet potato,North China 117,(early),Nancy (late),and Kao Tian Zi (late) were planted on six different dates,1/6,16/6,1/7,16/7 1/8 and 16/8 1957 to observe their enlargement of tubers and the growth of the topson fixed periods.1.The vine growth rate of sweet potato was much affected by the differences of variety andplanting date.In Ya-an district,Szechwan Province when the planting date of the cuttings wasbefore the middle part of July,the maximum increment period of the stem length,the shootemergence and the leaf development as well as the maximum weight increment of the topsappeared in the middle part of October,but when the planting date delayed to August,it didnot appear until the later part of October,the mean temperature by that time dropped to orunder 18℃,thenceforward no matter earlier or later planting the stem grew extremely weak,more shoots and leaves withered,the weight of the tops decreased gradually.Among thevarieties,the flourishing growth period of the early variety came earlier and went to the leafwithering stage earlier too.2.The planting date affected the size and weight of the tubers especially markedly.Thetubers'of the vine planted before summer solstice were larger and heavier than those of plantedafter the middle part of July.The early variety decreasing in production due to late plant-ing was not so much as the late variety.In the mean time,the early variety started itstuber enlargement earlier and more quickly than that of the late variety.Though it was plantedas late as the middle part of August,it still produced 250 grams of tuber per plant.As to the value of T/R (top/root),the cutting planted earlier was lower than that ofplanted late.Moreover,the variation of T/R value of different planting dates in an earlyvariety was not so great as in a late variety.Therefore,in late planting,the early varietymight be more valuable from the economical point of view. 3.With same length of growing peroid (75 days) and nearly the same effective “ac-cumulated temperature”the tuber production of cuttings the first 60 days under 25℃ andthe next 15 days under 20-22℃ was better than that of cuttings under 23-27℃ the wholetime.If the time under high temperature was shorter than 50 days,even thenceforwardthey were given a longer time under a moderate temperature,their tuber production wouldalso decrease.Apparently,when the time of high temperature was too short,the vine growthlowered down,and thus,such condition would not be favourable to tuber enlargement.In thispoint,an early variety suffered less than a late one,for the early variety could use the shortgrowing period more efficiently.4.Cuttings had the same 90 days remaining in a higher temperature in the first part ofthe growing period,then the longer time to grow in the later part of their life,the greatermean daily increment in tuber weight would be.On the contrary,cuttings had the same90 days remaining in a lower temperature in the later part of the growing period,then,the shorter time to grow in a higher temperature in the first part of their life would havea smaller mean daily increment in tuber weight.Among varieties,the late variety had agreater degree of variation than the early ones.5.The results obtained in this experiment have showed that in Ya-an district Szechwan,the cuttings of sweet potato for autumn crop should not be planted later than the middle partof July and in order to guarantee a satisfactory yield,early variety should be used.

本文就不同品种在不同插苗期的试验,分析研究其茎蔓生长及块根膨大的相互制约及其与温度条件的关系。初步结果认为:甘薯生长前期的高温日数应不短于60—90天,且后期要有一定适温日数,对块根膨大才有良好作用。晚熟种对前期高温日数要求较长,而早熟种则可相对较短。

Hydration of high alumina cements made by sintering process in rotary kiln is investiga-ted. Under 20℃ curing, the main hydration products of all of the three kinds of cements with successive higher CaO/Al_2O_3 ratios are CAH-(10) (not C_2AH_8) and alumina gel, i. e., they are essentially the same as the hydration products of the cement made by fusion process as generally reported. The hydration products of cement having a lower CaO/Al-2O_3 ratio or a higher CA_2 content are more stable.The...

Hydration of high alumina cements made by sintering process in rotary kiln is investiga-ted. Under 20℃ curing, the main hydration products of all of the three kinds of cements with successive higher CaO/Al_2O_3 ratios are CAH-(10) (not C_2AH_8) and alumina gel, i. e., they are essentially the same as the hydration products of the cement made by fusion process as generally reported. The hydration products of cement having a lower CaO/Al-2O_3 ratio or a higher CA_2 content are more stable.The formation of more basic hydrated aluminates (i. e., C_2AH_8 or C_3AH_6) and gibbsite of this kind of cement occurs at a higher curing tempera-ture.While the latter subjects to the same curing temperature as the cement of higher CaO/Al_2O_3,its initial products will be stable unless it subjects to a longer curing.Under various curing tempe-ratures, the variation of strength of the three cements can be explained by the difference in stability of the hydration products, cement of higher CaO/Al_2O_3 ratio providing the lowest thermal stability of the hydrated products and decreasing in strength of the paste under higher temperature.

研究了三种CaO/Al_2O_3不同的矾土水泥的水化,常温下的主要水化产物都是CAH_(10)(而不是C_2AH_3)和氧化铝胶滞体,与熔融法制矾土水泥是一致的。CaO/Al_2O_3小的水泥具有较好的稳定性,表现在生成或转化为高碱性水化铝酸钙(C_2AH_3或C_3AH_6)和三水矾土(AH_3)的温度较高;在同一养护温度下,水化物转化需要的时间亦较长,三种水泥在不同养护条件下的强度变化规律可从其水化产物的稳定性得到说明,即CaO/Al_2O_3比大的水泥生成的水化物热稳定性最差,高温下强度降低更甚。
