Soybean is a crop that uses more water. In order to promote the growth of leproductive organ and increase the number of flowers and pods, irrigation should be conducted when the relative humidity in soil less than 65% from seeding stage in chernorems. But it' s not suitable to irrigate more, and it needs to control the elongation of internodes so as to prevent lodging in later growing period.During the period from flowering to pod filling, both vegetative and reproductive growth are the most vigorous, and the water consumption of soybean is the greatest,too. If the relative humidity in the soil can be maintained above 85%,both the growth and seed yield of soybean will achieve the highest level. Seed filling can be promoted, abortive seeds can be reduced and the 100 seeds weight and yield can be increased if water supply is plenty enough.Irrigation should be done if the water content of soil is decreased below 65% or 70%.

试验表明:大豆是需水较多的作物。为了保证其生育有一定的繁茂度,和促进生殖器官的健壮生长,增加开花、结荚数,一般在黑土地区苗期至分枝期土壤含水量占最大持水量的65—70%以下时,就要进行灌溉。但此时灌水量不宜过多,过多就会降低地温,影响生育或招致节间伸长,生育期易徒长倒伏。大豆在开花之后,鼓粒以前需水最多,土壤含水量在占最大持水量的85%时,生育最佳。但在大田条件下很难达到,一般占最大持水量的80%,就可满足需要。鼓粒后需水量虽逐渐减少,但也不能低于占最大持水量的75%,当降到70%以下时,即要进行灌溉。灌溉方法因地势和条件而不同。一般平地可沟灌,岗地需要喷灌,以满足大豆对水分的需要。

This article deals with the studies on the mineral nutrition level of the leaf and fruit of the two Litchi varieties : Nuo Mi Ci and Huai Zhi, so as to understand their mineral nutrition level and their variation in amount during the fruit's developing stage.The results of studies showed that the nutrition levels of leaf and fruit of Litchi changed to different extent and to certain proportion in various vigorous plants of different varieties. The dry mitter of the young fruit contained mainly N, while the mature frujt contained nearly equal amount of N and K. In regard to the variation of mineral content diring the overall fruit's developing stages, the N in the leaf was most sensitive, K was less in extent and P was relatively stable. The curve showing the changes in the nutrition level of flowers and fruit corresponded to the '[ (' curve, and this phenomena was preliminarily recognized as the cause of abortive seeds. When the false testa grew rapidly, the quantities of N,P ard K increased rapidly, firally they became 2 to 5 times higher than the maximum amount contained in the leaf.The content of mineral was different in proportion in different part of the fruit in various varieties, the amount of nutrition needed by them was also different, fcr example, the whole small-seed fruit Nuo Mi Ci contained more K than that of the big-seed Huai Zhi. On the other hand, the N content in Huai Zhi was higher than that of Nuo Mi Ci. But the P content in both cases was more or less similar. In regard to the distribution of elements in different part of the fruit ,N was highest in seeds, it reachedas high as 60.09-60.40%, the content of K was lesser, and P was the least; while the flesh of the fruit was just the opposite, the K content was highest, as much as 50.23-r2.305%, N was lesser than K, P was the least among all, ard these conditions were similar in both varjetice.

本文通过对糯米糍、淮枝二个品种叶片和果实矿质营养的研究,以求了解荔枝在果实发育期间,叶、果的矿质营养水平及其变化。 研究结果表明:荔枝叶片和果实营养水平,随着果实发育,出现不同程度的变化,并构成一定的比例。不同品种的壮健植株,叶片矿质营养比值相近,幼果干物质以N为主,成熟果实N、K含量几乎相等。果实发育全过程矿质营养的变化,叶片中N的反应最敏感,K次之,P相对稳定。花和果实营养水平的变化曲线构成“”型,这种现象初步认为与种子败育有关。当假种皮迅速生长时N、P、K含量激增,最后达到超过同期叶片最高值的2~5倍。不同品种,果实各部分所占的比例不同,其所需营养也有差异,细核果的糯米糍全果含K量比大核果的淮枝多。反之,淮枝的N值比糯米糍高。P的水平二品种相近。各元素在果实各部分的分配以核含N最高,达60.09~60.64%,K、P次之,果肉则相反,以K含量最高,达50.25~52.30%,N、P次之,二品种相似。

To evaluat the effect of water-logged condition on seed vitality and plant growth of soybean, the following experiments were conducted: (l)Soybean seeds of 22 varieties were soaked in water for 6 days, water depth was 4cm over seeds; (2) Rhizosphere excess water environments from V3, R1, R3, and R5 growing stage were established for 15 days in the pot with soil. The water level reached the truelesves.Results from experiments suggested; (1) There was the relationship between the injury degree...

To evaluat the effect of water-logged condition on seed vitality and plant growth of soybean, the following experiments were conducted: (l)Soybean seeds of 22 varieties were soaked in water for 6 days, water depth was 4cm over seeds; (2) Rhizosphere excess water environments from V3, R1, R3, and R5 growing stage were established for 15 days in the pot with soil. The water level reached the truelesves.Results from experiments suggested; (1) There was the relationship between the injury degree of seed vitality and critical injury time. Injury degree speeded up and its critical time moved up under the condition of relative high temperiture. And there were varietal differences on the injury degree of seed vitality. (2) The mean yield of 22 varieties treated on in V3, R1, R3 and R5 decreased by the average of 35.1,40.2, 38.3 and 36.9%, respectively. At the vegetative stage (V3), the direct effect of injury by excess water was the vegetative orgens, but formations of yield components were affected by the reduced vegetation (reel- uced number of seeds by 38.8%). At flowering stage (R1), a great number of flowers shed caused, pods and seeds to reduce by 54.7 and 52.6%, respectively. At pod setting stage (R3), pods shed by 42.4%, and for that reason, seeds reduced by 45%. At seed filling stage (R5), a number of seeds reduced by 35.7% besides the weight of 100-seed reduced by 12.8%. Abortive seeds produced in pods the seeds just began to fill as result of excess water. In brief, there was relationship between percentage of soybean yield reduction and reduced rate of seeds. The correlation coefficient (r) was 0.957, 0.935, 0.930 and 0.480 at V3, R1, R3 and R5, respectively. There also appeared to be varietal differences on the reduced yield percentage under rhizosphere water-logged condition. And tolerance to the water-logged condition was not completely identical on different growing stages of the same variety. Besides above, the following adaptive variation to the environment of exessive water produced: stem in water thickened and loosened, and aerial roots growing out from stem under water. As soon as aerial roots grew out, the green colour of leaf recovered gradually.

渍水(种子上3cm水层)条件下,萌动种子活力的受害程度、临界时间与温度有关,相对高温下,种子受害加速,受害临界时间也提前。大豆生育的不同阶段根际渍水,产量均有大幅度下降。供试22个大豆品种(品系)在V_3、R_1、R_3和R_5期开始渍水15天的平均结果,分别减产35.1、40.2、38.3和36.9%。营养生长阶段渍水,株高下降、茎重减少,健壮“骨架”形成受阻造成单株粒数减少。开花期渍水,大量落花和成荚率减少影响单株粒数。结荚阶段渍水,因大量落荚,而影响单株粒数。鼓粒期渍水,一是开始鼓粒的种子因停止其发育而造成秕粒,二是鼓粒旺期的种子生长受阻而百粒重严重下降。总之,V_3、R_1、R_3和R_5期开始渍水的处理,减产均与其单株粒数的减少呈显著正相关。相关系数(r)分别为0.957、0.935、0.930和0.480。渍水还造成大豆对根际缺氧环境的适应性变化:如水中茎的增粗、大量增生气生根。随着气生根的生长发育,地上部,尤其是叶色逐渐有所恢复。大豆萌动种子受害临界及生育期根际渍水,对产量的胁迫存在着显著的品种间差异。品种内时间不同生育期的耐渍水性也不一致,这就给选育耐渍水大豆材料提供了成功的可能。
