1.A close relationship is existed between the proper water content of soil and the incre-ment of flowers and prevention of pod-shedding of soybeans.Number of pods borne on a single soybean plant as well as seed yield would decrease and pod-shedding rate would increaseas the plant suffered from drought during flowering and pod-bearing stage.The suffering isparticularly severe if drought occurs in late July when soybeans are on full-blooming-stage.Under such condition the growth and development of soybean plant would be hindered andless vigorous;pod-shedding rate would sharply increase while seed size would be larger.InAugust when pods are on forming-stage,drought would cause less damage on plant vigor butpod-shedding rate would be comparatively high,seed size would noticeably decrease,andpod-formation-stage 70%,and pod-filling-stage 60-65%.The experimental results of the past several years have showed that,in the leachedchernozen soil region of North East of China,the proper soil water content (in per centof water holding capacity) of the 0-5 50 cm.soil layer of the high yielding soybean field duringdifferent soybean growing stage should be:branching-stage 55-60%, blooming-stage 60-70,%,pod-forming-stage 70%,and pod-filling-stage 60-65%.2.If the density of stand and planting method are regulated according to soil fertility,number of pods per unit area would greatly increase,owing to that under such conditionsillumination and soil fertility can be fully utilized by soybean plants,and resulting in theincrement of photosynthetic rate and accumulation of photosynthetic products.Under lessfertile soil when variety Small Golden Yellow No.1 is used,and row distance is 60 cm.,thesuitable density of stand would be 250-300 thousands of plants per hectare.Under more fertileconditions the suitable density of stand should decrease to 100-150 thousands of plants perhectare.As to the method of planting,on fertile soil the 45×45 cm.square method with 3-5plants in each hill is much better than drilling method of which the distance between rows is50 cm.or 60 cm.Under square method,both of the rate of pod-bearing and the rate of pod-shedding of soybeans are high.When potato or wheat is interplanted between the rows of soybean,utilization of illumina-tion and soil fertility as well as microclimatic conditions are greatly improved.This wouldeffectively raise the number of pods of the individual soybean plants.For interplantation2:2 or 3:3 ratio is recommended for the fertile soil.3.The best time of topping (on comparatively fertile soil) of soybeans is preliminarilyconsidered to be on late blooming-stage.Topping on branching-stage is next,while on earlyblooming-stage ranks the third.Fertilizers containing NK Show the best result when theyare applied on late blooming-stage,while P fertilizer gives best result when it is applied onbranching-stage.The spraying of 3% of superphosphate solution for 2-3 times on leaves of soybeans duringthe pod-bearing stage (early August) can reduce the rate of pod-shedding.4.The spraying of minor-elements on soybean plants during full-blooming- and earlypod-forming-stage can increase intensity of respiration and photosynthetic capacity,andthus,beneficial for the increase of seed yield.The proper concentration of ammoniummolybdate solution sprayed during full-blooming-stage and early pod-forming-stage is 0.05%,while that of zinc sulphate sprayed during full-blooming-stage is 0.01%.5.Paying great attention to fieid management and adopting the practice of deep plowingare effective measures to promote soybean plants to have a vigorous growth and to bear moreflowers and pods.

Distance coefficients(Euclidean distance)were estimated among all possible pairs of locations. Such an analysis would be useful for the selection of...

The data on the yield, number of grains per spike and weight of 1,000 kernels obtained from Wheat cultivar regional test in the Lower Yangtse Valley were used to group locations according to the similarity of genotype ×location effects by cluster analysis. Six or seven genotypes of wheat were planted in thirteen locations from 1979 to 1983 for four crop seasons. Distance coefficients(Euclidean distance)were estimated among all possible pairs of locations. Such an analysis would be useful for the selection of testing sites for early generation testing and for development of genotypes with wide or narrow adaptability.The weight of 1,000 kernels of check cultivar was the best data to group locations. The 13 locations were grouped into 10 clusters with respect to their Weight of 1,000 kernels of check cultivar distance in a 4-dimensional space (4 years).The groups were as follows:A.East to the Grand Canala.Eastern plain1. Suzhou, 2. Nantong(Rudong)b.Law ground of riverside3. Wujin, 4. Changshu, 5. Xinghuac. Seaboard sandy soil region6. Yancheng and DafengB.West to the Grand Canald. High sandy region7. Yangzhoue.

应用长江下游地区小麦品种区域试验1979—1983年4个小麦生长季的产量、每穗粒数和千粒重资料,分别按其基因型×地点效应的相似性进行聚类分析。6—7个小麦材料种在13个试点。计算各试点间所有可能成对的78个欧氏距离系数。此种分析有助于为选择确当试验地点以研究早期世代和品种适应性的宽窄提供参考。结果表明,本试验中区试地点分类上用对照品种多年多点的千粒重资料为变量,聚类效果较好。按其4年千粒重的距离,13个区试点可分为2片、6区、10组。一、大运河以东片。包括:(一)东部平原,有苏州、南通(如东);(二)沿河低地,有武进、常熟、兴化;(三)沿海砂土区,有盐城、大丰。二、大运河以西片。包括:(四)高砂土地区,有扬州;(五)丘陵区,有镇江、仪征,南京;(六)沿江、沿湖区,有江浦、金湖。最后根据聚类结果,对区试点的调整问题进行了讨论。
