The results showed that Texuan cucumber and Yantai ground cucumber had good commodity characters,good taste and high yield,and their output value exceeded 16 000 yuan/666. 7 m2,so they are more suitable for open cultivation in Yantai region. The next ones are Meiyu Diguawang and Aweishi ground cucumber.展开更多
In order to make clear the effects of rain shelter cultivation on the incidence of diseases and pests of grape in Shandong Province,with Summer Black as the material,the diseases and pests of grape under rain shelter ...In order to make clear the effects of rain shelter cultivation on the incidence of diseases and pests of grape in Shandong Province,with Summer Black as the material,the diseases and pests of grape under rain shelter cultivation and open field cultivation in Tai'an and Jining were investigated.The results showed that under the rain shelter cultivation condition,the phenological period of grape delayed 5-8 d.The types of grape diseases and pests under the rain shelter cultivation were the same as those in the open filed cultivation.The most serious pests were Apolygus lucorum,followed by Lycorma delicatula,Erythreura apicalis and Thrips tabaci.The most serious leaf disease was downy mildew,and the most serious disease of grape berries was grape sour rot.Compared with the open field cultivation,the rain shelter cultivation could effectively reduce the incidence of pests and diseases in grape leaves and fruit.At the end of May 2018 and 2019,the occurrence rate of grape pests under the rain shelter cultivation in Tai'an reduced by 57.69%and 60.47%,respectively,and those in Jining reduced by 72.22%and 62.50%,respectively.In the middle of July of 2018 and 2019,the incidence of grape fruit diseases under the rain shelter cultivation in Tai'an reduced by 62.49%and 50.07%,respectively,and that in Jining reduced by 49.96%and 100%,respectively.展开更多
