The growth vigor tends to be strong and the first female blossom produces on the 4th or the 5th internode. Fruit is 34 cm long and 32 cm in transverse diameter. Per fruit weighs about 230 g. lt is dark green, densely covered with thorns. lt tastes crisp, containing 167.7 mg/kg Vc, and it is resistant to downy mildew, pow-dery mildew and bacterial angular leaf spot disease. lt is yielding and tolerant to low temperature and weak luminance. The yield can be as high as over 112 443.778 kg/hm^2, and ‘Oriental Show’ is suitable to be cultivated in greenhouses in early spring or solar greenhouses in north China or Henan province.展开更多

In the new period, the government should redefine its role in advancing the socialization of the old-age service. The level of socialization of old-age services is not high, the lack of vitality of the pension market, the imperfect system and other problems arise because the government is not clear. The government should deal with the relationship between the main body of the market and avoid the ＇double failure＇ of the government and the market. The government should play a guiding role in the policy, laws and regulations and other aspects of good service work for the social services of the elderly to provide a good development environment.展开更多

文摘In the different stages of the development of the old-age service, the responsibility and function of the government will be different. In the new period, the government should redefine its role in advancing the socialization of the old-age service. The level of socialization of old-age services is not high, the lack of vitality of the pension market, the imperfect system and other problems arise because the government is not clear. The government should deal with the relationship between the main body of the market and avoid the ＇double failure＇ of the government and the market. The government should play a guiding role in the policy, laws and regulations and other aspects of good service work for the social services of the elderly to provide a good development environment.
