The millet blast has been considered as one of the serious diseases of the millet crop in Inner Mongolia and North China since long. However, our knowledge of this disease is meagre. The present paper is a report of a series of studies carried out in Shouchang, Shangtun during 1958 and 1959. The most important source of primary infection of the millet blast is revealed to be the fungus borne on or in the seeds.

The millet blast has been considered as one of the serious diseases of the millet crop in Inner Mongolia and North China since long. However, our knowledge of this disease is meagre. The present paper is a report of a series of studies carried out in Shouchang, Shangtun during 1958 and 1959. The most important source of primary infection of the millet blast is revealed to be the fungus borne on or in the seeds. A seed-treatment with 0.3% Ceresan reduced the diseased seedlings from 80% to 30% in one variety and from 13.3% to 6.6% in another. In fields where the millet straws are left in piles during the winter, the disease indices of the seedlings are greatly increased. It is pointed out that the overwintering fungus in the diseased straws is also one of the sources of primary infection. Different varieties of millet show various degrees of resistance, however, none of them is immune. Varieties are grouped under four types according to their reactions to the disease: (1) very susceptible both at seedling and heading stage, e.g. Muli and Huanun No. 4, (2) comparatively resistant throughout the growing season, e.g. No. 322 and Ginshientz, (3) higher resistance at seedling stage, but susceptible at heading, e.g. Shiaohuango, Paimuchi, No. 231 and Shansidayieh, and (4) susceptible at seedling stage but more resistant at heading, e.g. Dapaigo, No, 611 and Titoupeng. Inspite of all such difference, all varieties show a significant depression of disease development during the time of shooting (about June 7 to 13). The late sowing fields happens to yield less diseased seedlings than the earlier ones. The application of ammonium sulphate as a fertilizer shortly before sowing increases the disease index of the seedlings. The disease index of a dense planting field (6000 plants per Mou) is decidedly higher than those of less dense ones (5000, 4000 and 3000 plants per Mou). The ratio of the disease indices of these cases ranges from 1:1.7 to 1:6. The measurments of dew quantity on the millet plants (adopting Prof. Chiu's method of measuring relative quantity of dew condensed on leaves of plant, expressed in g/25 cm~2) reveal that the disease development is correlated directly with the relative quantity of dew condensed during the night. Such relationship is especially significant when precipitation water is scanty. More condense water is recorded in denser planting fields. The millet blast is rapidly developed when the temperature is about 25.5℃, the relative humidity above 75%, the relative dew quantity above 350 mg/25 cm~2 or the precipitation not less than 2.5 mm. Suggestions are made for combating the disease by employing resistant varieties, seedtreatment and the early thorough removal of the millet straws away from the field.

粟瘟(Piricularia setariae Nishikado)是关內外、魯西一带谷子上常見的病害,严重时引起苗枯、叶瘟、頸瘟,損失极大。种子及谷草带病是苗期粟瘟的主要侵染来源。經过种子处理者(温湯浸种,0.3%西力生拌种)发病率較未处理者減輕14—62%。野生寄主侵染来源作用还不明瞭。不同品种間对粟瘟的抗病性不同。苗期、抽穗期均感病者有磨里、华农四号;苗期、抽穗期均抗病者有三三二、金綫子;苗期較抽穗期病輕者有小黃谷、白母鸡咀、二三一;抽穗期較苗期病輕者有大白谷、六一一、鉄头碰。早播(4月17—22日)較晚播(4月24—27日)者发病重,但早播結合种子处理較晚播不处理者病輕。不施硫胺种肥者較施用不同量种肥的苗期发病率低,但到抽穗前后差别漸消失。高度密植(每亩6万株)的比一般密度(每亩3万株)病情指数增加50%以上。田間相对露量与病情指数一致。密植田6万株的比一般田3万株的在苗期露量增高20%,抽穗期增高26%以上,但两者抽穗期間露量均比苗期为高。密植田增高23%,一般田增高14.7%。在17个品种观察中,1959年粟瘟病出現二个高峯,第一个高峯在苗期2—3片真叶开始,5月17日前,这时普遍发病,病株率在1...

粟瘟(Piricularia setariae Nishikado)是关內外、魯西一带谷子上常見的病害,严重时引起苗枯、叶瘟、頸瘟,損失极大。种子及谷草带病是苗期粟瘟的主要侵染来源。經过种子处理者(温湯浸种,0.3%西力生拌种)发病率較未处理者減輕14—62%。野生寄主侵染来源作用还不明瞭。不同品种間对粟瘟的抗病性不同。苗期、抽穗期均感病者有磨里、华农四号;苗期、抽穗期均抗病者有三三二、金綫子;苗期較抽穗期病輕者有小黃谷、白母鸡咀、二三一;抽穗期較苗期病輕者有大白谷、六一一、鉄头碰。早播(4月17—22日)較晚播(4月24—27日)者发病重,但早播結合种子处理較晚播不处理者病輕。不施硫胺种肥者較施用不同量种肥的苗期发病率低,但到抽穗前后差别漸消失。高度密植(每亩6万株)的比一般密度(每亩3万株)病情指数增加50%以上。田間相对露量与病情指数一致。密植田6万株的比一般田3万株的在苗期露量增高20%,抽穗期增高26%以上,但两者抽穗期間露量均比苗期为高。密植田增高23%,一般田增高14.7%。在17个品种观察中,1959年粟瘟病出現二个高峯,第一个高峯在苗期2—3片真叶开始,5月17日前,这时普遍发病,病株率在10—67%左右,以后病势停止发展,随着植株的不断生长,新叶抽出,老叶病叶枯死,到6月1日左右病情指数显著下降,到抽穗期病情指数又普遍上升,出現第二个发病高峯。在定点定株田間小气候观察中,可見5月下旬至6月3日前气温为24—25℃,相对湿度不足60%,有风无露,病害停止发展,病情指数下降。6月4日后有阴雨,两天內降雨量为20毫米,气温平均为19%,相对湿度达到85%,夜間无风有露,病情指数上升。6月10日后連續干旱,气温在27℃,相对湿度在49%,半月内仅4天有露量,植株下部叶片干枯,病情指数下降。6月26日后有阴雨,露量增加,平均气溫25.5℃,相对湿度为75%,病害連續发展。根据上述研究对生产上防治粟瘟提出如下建議:(1) 結合消灭白髮病、粒黑穗病,严格实行种子处理。尤其早播地区,种子处理以溫湯浸种較好,0.3%賽力散拌种較差。(2) 合理密植,以每亩3—4万株为宜。过密生长不良,病害严重。(3) 谷子收获后,及时清除田間杂草、谷草,勿堆置田間,以減少初次侵染来源。在发病严重地区,可选用抗病品种,如三三二、鉄头碰等。

目前有很多不同类型的偏转仪,其中最出名的要算科前克及汤姆逊两种.科前克偏转仪虽是一个好的偏转仪.但它是为着130型罗经而设计的;而汤姆逊偏转仪的力(?)刻度是不合理的.因此设计一个通用的偏转仪就显得非常必要.现在已经设计出一个通用的偏转仪,这个偏转仪取名“十一”式编转仪.“十一”式偏转仪的优点不但适用于各种类型的罗经,而且还可适用于世界上任何港口.本文作者还提供了另一种测量指北力的方法、λ值的针算法以及(?)λH力的消除方法.

This paper describes a method of measuring the small frequency shift of a resonant cavity, as a perturbation is introduced in it. This is an important problem on the measurement of R/Q of a cavity or the interaction impedance of a slow wave Structure. The method is based on the principle of automatic frequency tunning, i.e. tunning a reflex klystron oscillator tracking the resonant frequency of the cavity to be measured automatically by means of a discriminator. The oscillation frequency of this system and the frequency shift after introducing the perturbation are then measured by a heterodyne frequency meter. Analysis and exprimental result show that, by this method, the minimum discriminating frequency shift is 10-5-5× 10-6 (relative value) in S-band, as the Q0.of the cavity is 500-1000.. The tracking error is about 2%.

本文叙述了一种当谐振系统中引入摄动以后,量测其谐振频率微小偏移的方法。这 是量测空腔谐振器和慢波系统耦合阻抗时所遇到的主要问题。 所用的方法基于自动频率微调的原理,即利用一套鉴频系统使反射速调管的振荡频 率自动地跟踪到被测腔的谐振频率。然后利用一高精度外差式频率计来测定该振荡系统 的振荡频率和经摄动后的频率偏移 计算和实验表明,用本文所述方法,当被测腔固有品质数为500~1000时,在S 波段可以分辨的最小频偏相对值达10-5~5×10-6跟踪误差约为2%。
