The sex expression of cucumber (Cucumis sativus L.) and Chinese white-floweredgourd (Lagenaria leucantha Rusby) was found to be controlled by foliar spray withethephon and gibberellin. Ethephon (2-chloroethyl phosphonic acid) at a concentration of 150 ppmcaused increase of femaleness and inhibition of male flower, and gibberellin causedincrease of maleness and inhibition of female flower. Under natural condition, Chinese white-flowered gourd produced nearly allstaminate flowers and very few or no pistillate flower on the main stem. As treatedwith ethephon, pistillate flowers may produced at each node from 10th to 20thcontinuously. But the sex expression on the side branches was little affected. The number of pistillate flowers of both cucumber and Chinese white-floweredgourd was greatly increased by ethephon treatment, but their yields were not pro-portionally increased, due to the decrease in percentage of fruit setting. The degreeof yield increase varied with varieties, environmental conditions and cultural practice. When ethephon of 150 ppm was applied in combination with giberellin, thestimulatory effect of ethephon on femaleness was suppressed by high concentration(1500 ppm) of gibberellin, but not by low concentration (50 ppm). The stimulatory effect of ethephon on sex expression of cucumber had a periodof persistence. When the young cucumber plants were first sprayed with ethephon,and then with 1500 ppm gibberellin within 8, 12 or 24 hours, femaleness was in-creased. After 48 hours, however, no appreciable effect of gibberellin treatmenton sex expression was observed. Evidence was also found that ethephon treatment stimulated, and gibberellininhibited the activity of peroxidase of the cucumber stem tip tissue. When ethephonwas applied in combination with gibberellin, however, the activity was nearlythe same as that treated with ethephon alone.

黄瓜(Cucumis sativus L.)及瓠瓜(Lagenaria leucantha Rusby)幼苗期间,用乙烯利(150ppm)喷洒处理,可以明显地增加雌花的发生,减少雄花的发生;而用赤霉素处理可以增加雄花的发生,而减少雌花的发生。 瓠瓜的主蔓很少着生雌花,而只生雄花。经乙烯利处理后,可以连续十余节都着生雌花,因而从根本上改变了瓠瓜的开花习性。但对于侧蔓上的雌雄性别的影响很少。 乙烯利处理,可以大大增加黄瓜及瓠瓜的雌花数,但对于产量的影响,因品种特性,及栽培技术而不同。其中以早期产量增加较明显,而总产量不一定增加。 当乙烯利与赤霉素混合处理时,对性别表现的效果,要看赤霉素的浓度来决定。高浓度(1500ppm)的赤霉素可以抵消乙烯利对性别表现的作用,低浓度(50ppm),不能抵消乙烯利的这种作用。 乙烯利促进黄瓜多生雌花的效果有一定的持续时期。在处理后8,12,24小时后,再喷高浓度赤霉素会增加雄花数及降低雌花数,但48小时以后则几乎没有什么作用。 黄瓜幼苗经乙烯利处理后,会增加其茎端组织的过氧化物酶的活性;而赤霉素处理,会抑制过氧化物酶的活性。

In order to solve the problems of serious virosis and low yield of tomatoes and to probe how to form a complete set of cultural practices for high yield and low cost, a field experiment on cultural system, sowing period, suitable varieties and protection from diseases and insects was carried out in Baoding in 1983—1984. The result of the experiment showed that, the plastic middle shed had a significant effect on lowering temperatures during the high temperature season(from early july to mid-August)....

In order to solve the problems of serious virosis and low yield of tomatoes and to probe how to form a complete set of cultural practices for high yield and low cost, a field experiment on cultural system, sowing period, suitable varieties and protection from diseases and insects was carried out in Baoding in 1983—1984. The result of the experiment showed that, the plastic middle shed had a significant effect on lowering temperatures during the high temperature season(from early july to mid-August). The highest air temperature within the shed in the mid-july was decreased by 0.8—8℃ and the soil temperature at 5 cm under ground surface was decreased by0—4℃ as compared with the open air. About 95 days after sowing, the harvest was begun. The period mentioned above included the seedling stage of more than 20 dags, The first flower bud stage of more than 20 dags, 7—8 days for bloom and 45 days for fruit development. Direct sowing with the cover of plastic middle shed to culture autumn cropping tomato showed effective control of virosis and its yield per mu could reach more than 4500 jin. The result of primary experiment showed that the optimum period of sowing autumn croping tomato was in early july. It is desirable to select the varieties which are hot-tolerable, virosis-resistant and of high yield such as "Qang li mi shou" (a. cv. from Japan ), "Floride" and "manalucie". The spacing at 43×23cm should be kept and four clusters of fruits per plant should be left. From the beginning to the end of september spray with Decis 2.5% 6000×water solution should be carried out 2—3 times, the first spray was carried out when the flowers of first inflorescence dropped. Catton-ball warm basically can be controled by this mothod.

为解决秋番茄毒病重、产量低的问题,1983和1984年在本校标本园进行了栽培方式、播期、品种和病虫防治等试验。研究结果表明,利用塑料薄膜中棚直播栽培秋番茄,能有效的防治毒病。适宜播期为7月上旬,最晚不超过7月10日。品种应选择耐热、抗毒病、高产的强力米寿和佛罗暑德等。行株距为1.3×0.7尺,留4穗果。9月初第一花序谢花后开始喷2.5%的溴氰菊酯6000倍液,到9月中、下旬共喷2—3次,可基本控制住棉铃虫危害。后期加强通风,可避免晚疫病的发生。
