Studies On The Cultivation And Applied Agricultural Chemical Technology Used In The Introduction Grape Varieties In Sand-Soil

This article gives a systematic research on the growth habits, fruit charactics, phonological periods, resistances and adaptabilities of 16 grape new varieties, which are introduced from Liaoning fruit institute and planted in the sand soil, in the same time, the applied pesticide technology on the local main pests and diseases of grape have been reseached. The results show that:1,According to16 varieties of grape, a large number of habits about botany and ecology have been got.In Yulin region, the adaptability of 87-1,Red Globe,Tengren, Xiyanghong and Guixingyi are best, followed by Huangguan,Lizhamate,Red Fuji, Heiaolin, Xianfeng and Jufeng,with Jingya,Ziyu,Kangtai and Canadice showing bad adaptability.2,When the roots of young grape plant or grape cutting were binded with the pesticide-mud (PhoximEC50,20ml with CarbendazimWP20g and earth 20kg mixed together) before transplanting , they could avoid partly to be damaged by underground pests and root diseases.As a result, the survival rate of grape plant and grape cutting increased by 4.3﹪and 12.2﹪respectively.3,The poison bait ,which is made of the poplar leaf soaked in the solution of TichlorphonSD90,80g with water20kg mixed together for 5-30min ,can well control the sand insect of Diglossotrox alashanicus Suvrov.4,It was discovered that the best time for spraying to control the leaf yellowing of grape was the period when the grape was near the blooming(late in May, during this period, the symptom of leaf yellowing didn't emerge yet .).By putting 0.3kg FeSO4 into the earth near each grape tree roots, a control effect of above 70﹪can been made.5,The germicide of 12.5﹪metalaxyl+37.5﹪phosethy1-Al was used successfully to control the Plasmopara viticdola late in the May, when the symptom hasn,t emerged yet,3times,10-day intervals.The innovations of this article are:①the technology of pesticide-mud applying in the grape cultivations is successful;②a systematic study on the chemical control of Diglossotrox alashanicus Suvrov was made the first time in our country.
