Sweet-potato wilt,a dangerous disease of sweet potatoes,has made itsappearance for more than 10 years in several districts of the south-easternKwangsi and south-western Kwangtung.During recent years it has been found tocause a heavy loss of sweet potato crop in these two provinces. Sweet-potato wilt is a kind of wilt disease which infects the fibrovascular ??bundles of the plant.It begins to infect the vine cuttings and those parts thatare in close contact with the sick-soil.The infected parts first show the water-soaked appearance and then extend upwardly,and eventually become blackenedand rotted.As a rule,ths leaves of the infected plants show an abnormal coloror pale yellow,and drooping appearance.In the meantime,the root tips of theadventitious roots of the vines lose their cortex and begin to lot.Wilting followsquite rapidly and finally the entire plant dies.If the disease infects the plantafter the potatoes beginning to form,it may extend throughout the vine and in-to the roots,causing the enlarged roots to show brown streaks and finally blackenedand rotted with pungent odor. The cause of the disease may appropriately be considered as due to bacteriaand Fusarium spp.Four types of bacteria,i.e.white smooth type,yellow smoothtype,white rough type and yellow rough type,are able to cause the disease.Atleast four kinds of Fusarium,i.e.white aerial mycelium type,white mycelium withred of a purple tint substratum type,pink mycelium with red of a purple tint sub-stratum type and without aerial mycelium type are responsible for the disease.Which is the main cause of the disease? Either bacteria or Fusarium alone or theboth in combination is able to cause the disease,further tests should be madebefore a definite conclusion may be drawn. The dissemination of the wilt organisms may appropriately be considered inthree ways,namely,(1) by infested roots and vines,(2) by sick-soil,and (3) byinsects,as the sweet-potato weevil (Gycas formicarius Fabr.).The former twoways of dissemination are more definite than the latter,however,further testsand observations should be made. According to the results of 2-years field experiments in Tsen-shi and Peh-liustations,it shows that different varieties of sweet-potato possess different resis-tance to the disease.Among several varieties tested,it is found that Tai-nung No.3being a promising one,because it yields very high and is highly resistant to thedisease and to the drought.Although it is occasionally found to be susceptibleto the disease in the experiment field of Tsen-shi and is more commonly foundin the experiment field of Lin-kwei.The second variety is Tai-nung No.46 dueto its high degree of disease resistance. The results of preliminary tests indicate that the method of reproduction byold vines would decrease both in disease resistance and in yield within the samevariety. From tests conducted in two different fields,i.e.one at dry land and the ??other in the rice field,it shows that the discrepancies were found in the occur-rence of the disease and also in the relation of the method of manuring to thepercent of infection. Dipping cuttings in different disinfectants did not show any significant results.There are discrepancies in both plowed and sunned field test and two methodsof setting the vines test.These may be due to methods of treatment,landand varieties used for experiment being different. According to the results of date of planting tests in Peh-liu,it indicates thatthe occurrence and the development of the disease are closely related to the highhumidity and the high temperature.These climatic factors affect the health ofthe early growth of the plant which in turn would increase the disease resistance.It is suggested that the most suitable date for planting sweet-potato in Peh-liu isin the first decade of August. In comparing the weather records of the three districts—Lin-kwei,Peh-liu andTsen-shi—in relation to the date of early and last occurrences of the disease,itshows that an average air temperature of 23.4-28.4℃ is most suitable for the oc-currence of the disease,and an average relative humidity of 80 per cent is alsoneeded for the infection of the disease.Based on these facts,we may say thatsweet-potatoes in Lin-kwei are capable to be easily infected by the wilt organisms.except the last date of the infection would be preceded 10-20 clays.Any otherregions with similar climatic factors,it is also very possible to be infected. According to the results of 2-years experiments and facts from surveys,sug-gestive control measures are proposed: (1) excluding the disease by regulationthrough the use of quarantines enforced by an inspection station empowered torestrict or eradicate diseased roots and vines to prevent them from becomingsources of infection in disease-free districts; (2) selection of disease resistant varie-ties in combination with cultural practices such as the use of more ash,suitableamount of lime and manure,and suitable date of planting to enable plants toescape or resist the disease.For the present time,we suggest that the use of Tai-nung No.3 in Tsen-shi and Peh-liu may meet the requirement,and promotingthe method of root reproduction in place of an old method of reproduction byrepeating vine cuttings from old vines can prevent the degeneration of the plantand decrease the infection of the disease.

甘薯瘟是一种具有十余年历史的病害,不仅严重地威胁着广西东南部几县的甘薯生产,同时也严重影响了广东西南部和广西毗鄰的几个县的甘薯生产。甘薯瘟是一种枯萎类型的病害,是侵染維管束的脉管病害,首先侵染插条与土壤接触部位,先呈水漬狀,继而变黑腐爛并向上發展,叶色不正常或呈黄色而萎垂。此时薯藤的不定根根尖脫皮并开始腐爛,最后全株枯死。如在結薯块后才受病,除薯藤显现枯萎現象外,可向薯塊發展而呈褐色条斑,最后变黑腐烂,發出刺鼻臭辣气味。瘟薯的病原初步認为是由细菌和镰刀菌所致。细菌中可分为白色粘滑型,黄色粘滑型,白色干绉型和黄色干绉型;鐮刀菌中包括白色气生菌丝型,白色菌丝基層稍呈紫紅色型,粉紅色菌丝基層呈紫紅色型,无气生菌丝型等。但究以哪类为主导,抑系并發性呢?仍須进一步研究。薯瘟病原的傳播,初步認为有三种方式:带病薯块和薯苗,病土,及昆虫(如小象鼻虫等),其中以前二种較为肯定,后一种則仅属可能,仍有待+于进一步試驗观察。甘薯各品种間确具有不同的抗病性能,如台农三号的抗病性較强而产量最高,又能抗旱,台农46号的抗病性最高,但产量則較低,因而台农三号是最有希望的品种,但在岑溪試驗地,会略有發現蔓割病(可能是薯瘟病原之一),临桂試...

甘薯瘟是一种具有十余年历史的病害,不仅严重地威胁着广西东南部几县的甘薯生产,同时也严重影响了广东西南部和广西毗鄰的几个县的甘薯生产。甘薯瘟是一种枯萎类型的病害,是侵染維管束的脉管病害,首先侵染插条与土壤接触部位,先呈水漬狀,继而变黑腐爛并向上發展,叶色不正常或呈黄色而萎垂。此时薯藤的不定根根尖脫皮并开始腐爛,最后全株枯死。如在結薯块后才受病,除薯藤显现枯萎現象外,可向薯塊發展而呈褐色条斑,最后变黑腐烂,發出刺鼻臭辣气味。瘟薯的病原初步認为是由细菌和镰刀菌所致。细菌中可分为白色粘滑型,黄色粘滑型,白色干绉型和黄色干绉型;鐮刀菌中包括白色气生菌丝型,白色菌丝基層稍呈紫紅色型,粉紅色菌丝基層呈紫紅色型,无气生菌丝型等。但究以哪类为主导,抑系并發性呢?仍須进一步研究。薯瘟病原的傳播,初步認为有三种方式:带病薯块和薯苗,病土,及昆虫(如小象鼻虫等),其中以前二种較为肯定,后一种則仅属可能,仍有待+于进一步試驗观察。甘薯各品种間确具有不同的抗病性能,如台农三号的抗病性較强而产量最高,又能抗旱,台农46号的抗病性最高,但产量則較低,因而台农三号是最有希望的品种,但在岑溪試驗地,会略有發現蔓割病(可能是薯瘟病原之一),临桂試驗田也会發生过多次。老藤繁殖会降低同一品种的抗病性和产量,值得我們注意。在旱地和水田不同試驗地上所得結果,可初步说明發病情况很不一致,追肥与不追肥处理的發病率也不一致。藥剂处理种苗效应不显著,翻晒土壤及二种种植法試驗结果不一致,想与試驗方法、試驗地不同和供試品种不同有密切关系。薯瘟的發生与發展和高温潮湿有密切关系,而这些气候因素对于植株的早期生??長壮健及增强抗病性也有关系。初步建議,在北流地区以立秋(8月上旬)种植較为适当。从临桂雁山、北流和岑溪三处的气候記录,和薯瘟开始發生与最后發生日期的記录看来,可以初步說平均气温23.4—28.4℃最适于薯瘟的發生。相对湿度平均在80%以上亦适于本病的發生。由此可見,在临桂雁山地区,薯瘟可能是容易發生的,不过停止發病日期会提早10—20天。其他地区如有相似气温与湿度情况,那也是会發生薯瘟的。根据二年試驗結果和調查所得情况,初步提出防治薯瘟的办法如次:(1)应采取种薯和种苗的檢疫措,禁止病区的种薯运往無病地区,以防蔓延;(2)选育抗病品种为主,結合先进的栽培管理法;多草木灰,适当用石灰,根外追肥,适期种植等,以增强植株的抗病性,避免病害的侵染,保証丰产。目前在岑溪及北流地区,可先推广种植“台农三号”品种,并提倡以薯塊育苗,切勿采用老藤繁殖,以避免植株的衰退,减少薯瘟的發生。

When actinomycetes antagonist is cultured in the cotton seed cake and usedas a fertilizer for cotton,a stimulating effect on growth of the plant and a decr-ease of percentage of Verticillium wilt has been observed.The isolates of Actino-mycetes which have shown the best results are G_4 and 5406.Throughout thegrowing period,three applications of the antagonist carried fertilizer show a decr-ease of 31-50% disease and an increase of 14-40% yield.The three applicationsof the antagonist carried fertilizer seem to be better than that of two applications.However,the yield increase due to the fourth application can hardly cover the costof labour and material. According to the results of a burried-slide test for inspecting the dynamics ofthe antagonist in certain depths of soil,it is found that the actinomycetous isolatesG_4 and 5406 survive a comparativly longer period at a soil depth of 2.5-10 cm.,buttheir amount per unit volume of soil is gradually reduced with time.The anta-gonists are most abundantly distributed at a depth of 5-7.5 cm.It is suggestedthat three applications of the antagonist carried fertilizer may be practical in con-trolling the Verticillium wilt of cotton.

The present report deals with the results of some studies on the longevity of the soft-rot organism, Erwinia aroideae (Towns.) Holland in soil. It is found that when the bacteria are added into a mass of non-sterile field soil in a test-tube and incubated at 28℃, they can not live longer than 14 days. This result is somewhat contradictory to those of Patel, but agrees with those of Gorlenko and Voronkeviz. A study of the number of microorganisms which, are able to be plated out in beef bouillon peptone agar reveals that when a known number of soft-rot bacteria is added into a soil sample, the total number of the indigenous microorganisms is increased, while the number of the introduced bacteria is rapidly decreased. After 72 hours, the total number of the indigenous microorganisms in the soil sample begins to decrease and finally reaches its original level. It is inferred that following the addition of the soft-rot organism into a soil sample, a biological equilibrium is broken and the indigenous microorganisms are stimulated to multiply rapidly. After a brief period of such an unusual multiplication of the indigenous microorganisms, the invaders are suppressed and a new equilibrium is finally established. Henceforth the number level of the indigenous microorganisms in the soil sample returns to the orginal. When the soft-rot bacteria are introduced into the soil in soil tanks regulated at different soil temperatures (and in each tank two plants of the Chinese cabbage are planted), the introduced bacteria live 11 days at 35℃, 21 days at 10℃ and 7 days at 20℃. Possibly a soil temperature at 20℃ might be close to the optimal for the activities of some antagonists of the soft-rot bacteria. When a soil sample is fertilized with the "de-oiled soybean-seed-cake" or with the "dried night soil", the elimination of the intruding bacteria is accelerated. In the plot where the de-oiled soybeanseed-cake" is applied, the soft-rot organism disappears within 24 hours, whereas in the plot of the "dried night soil", the intruding bacteria disappear within 5 days. The soft-rot bacteria in an autoclaved field soil sample live 96 days. When a quantity of manure or compost is added to the soil sample and chert autoclaved', the soft-rot bacteria introduced at such a condition live longer than 180 days. Evidently the added manure or compost in sterile condition serves as food material for the soft-rot organism.

白菜軟腐細菌(Erwinia aroideae)在不灭菌的土壤中可以存活11天至14天。土壤中的微生物总数(指可以在牛肉汁(月柬)培养基上发育的微生物)因軟腐細菌的加入而起剧烈的波动。当軟腐細菌进入土壤中后24小时,軟腐細菌的数量銳减而土壤中的其他微生物数量上昇,以后亦逐漸递減。当軟腐細菌在土壤中消失时,土壤微生物的数量又趋于平稳。軟腐細菌在栽有白菜的土壤中,土壤温度影响其存活期:土温在35℃时可以存活11天,在10℃可以存活21天,在20℃时可以活7天。豆餅及大粪干入土壤中时可以促进軟腐細菌的消灭。豆餅区(豆餅微粒与土壤拌匀)在24小时中软腐細菌即已消灭,而在大粪干区軟腐細菌可以存活5天。軟腐細菌在灭菌的土壤中可以活96天,如果以灭菌的堆肥或厩肥时,可以延长至180天以上。
