日光温室西葫芦套种苦瓜无公害栽培模式,自2011年在千阳县有机王蔬菜专业合作社设施蔬菜基地推广以来,以其病害少、高产、高效、易管理,深受菜农欢迎,栽培面积不断扩大。该模式根据西葫芦较耐寒而不耐热、苦瓜喜温耐热的特性,在冬季至来年3月份前以西葫芦生长为主,而苦瓜深冬季节生长缓慢,对西葫芦影响不大,3月底西葫芦长势转弱、价格降低,拉秧后转入以苦瓜生产为主,苦瓜视市场价格情况在7月份拉秧。该模式充分发挥了日光温室反季节栽培的优势,规避了市场风险, 相似文献

Extracts of phenolic compounds from maturing Red Delicious apple tissues containing p-coumaryl-quinic acids and chlorogenic acid were shown to be inhibitory to germination of Botrytis cinerea spores and mycelial growth of B. cinerea, Penicillium expansum and Alternaria sp. Measurements of the content of both acids during the growing season showed that the content of phenolic compounds was highest early in the season and decreased as the fruit matured. The decrease coincided with the rise in susceptibility of the fruit to rot caused by B. cinerea. The concentration of p-coumaryl-quinic acid was highest near the skin and lowest near the core. 相似文献

桃砧木筑波4号和筑波5号抗根癌病鉴定评价 总被引:2,自引:0,他引:2
以当年实生筑波4号(Prunus persica‘tsukuba-4’)和筑波5号(Prunus persica‘tsuku-ba-5’)的新梢为材料,采用人工接种发根土壤杆菌(Agrobacterium rhizogenes)的方法研究了其对根癌病的抗性及其分离情况。结果表明,筑波4号实生群体中免疫、高度抗病、中度抗病、中度感病和高度感病类型分别占0.90%、1.80%、9.01%、18.92%和69.37%。筑波5号实生群体中免疫、高度抗病、中度抗病、中度感病和高度感病类型分别占1.01%、3.03%、8.08%、38.38%和49.49%。筑波4号和筑波5号对发根土壤杆菌的抗性存在显著分离现象,可从中筛选出抗性极强的植株。 相似文献

三种杀菌剂诱导彩色马蹄莲抗细菌性软腐病的研究 总被引:1,自引:0,他引:1
以77%的多宁可湿性粉剂、20%的叶枯唑可湿性粉剂和1.5%的噻霉酮水乳剂为试材,研究了3种杀菌剂对彩色马蹄莲抗细菌性软腐病致病菌胡萝卜软腐果胶杆菌胡萝卜亚种生长抑制效果、圆叶片法室内诱导以及活植物室外诱导彩色马蹄莲抗P.c.c.病原菌等。结果表明:3种杀菌剂对P.c.c.抑制效果不同,叶枯唑效果最好,含1 000倍~125倍的叶枯唑的PDA培养基能完全抑制P.c.c.病原菌生长;室内圆叶片法能完全抑制菌的生长,室外抑制率高于60%;多宁效果次之,室外抑制率不到50%;噻霉酮无论是对菌的生长抑制还是室内和室外诱导,都不能完全抑制;1 000倍~500倍的叶枯唑彩色马蹄莲软腐病的抑制效果差异不大(P0.05)。 相似文献

Protecting semi-natural grasslands may through spill-over benefit species richness and abundance of flower-visiting insects in linear habitats, such as uncultivated field boundaries, in agricultural landscapes. However, whether local diversity increases both with decreasing distance from potential source habitats and increasing landscape heterogeneity is poorly known due to a general lack of studies replicated at the landscape scale. We analysed if local assemblages of bumblebees, butterflies and hoverflies in linear uncultivated habitats increased with increasing distance to the nearest semi-natural grassland in 12 replicated landscapes along a gradient of landscape heterogeneity in Scania, Southern Sweden. Species richness and abundance of bumblebees and butterflies, but not hoverflies, decreased with increasing distance to semi-natural grasslands, but none of these groups were related to increasing landscape heterogeneity. Further analyses on trait-specific groups revealed significant decreases in the abundance of sedentary and grassland specialist butterflies with increasing distance to assumed source populations, whereas this was not the case concerning mobile species and grassland generalists. The abundance of all bumblebee trait groups decreased with increasing distance to semi-natural grasslands, but only some species (those nesting above ground, with long colony cycles and with small colony sizes) also increased with increasing landscape heterogeneity. We conclude that local species assemblages of flower-visiting insects in linear habitat elements were mainly affected by the occurrence of nearby semi-natural grasslands. In order to conserve diverse assemblages of flower-visiting insects, including the ecological services they provide, it is important to conserve semi-natural grasslands dispersed throughout agricultural landscapes. 相似文献
