Study on absorption of nutrient elements and water of protectively cultivated ‘ Fenghou＇ grape
摘要
Abstract
[Objective]The study is to elucidate the nutrition and water absorption of grapevine [Method] The experimental material was 7-year-old Fenghou grapevine cultivated in perlite medium which could supply recycling Hoagland nutrient solution of high, medium and low concentrations （N concentration are 180 mg· L^（-1）, 120 mg·L^（-1） and 60 mg·L^（-1） respectively）, the absorption of water and elements such as N, P, K, Ca, Mg, Fe, Mn, B, Zn and Cu was investigated, and the contents of mineral elements in leaves and fruits in main phenophase were also analyzed. Meanwhile, the growth of grapevine stem and development of fruits were observed. [Result]The results revealed that： the absorption of nutrient elements increased with the growth of shoots after budbreak; the maximum daily absorption amount appeared in the period from the rapid expansion to maturity of berry, the total absorption amount of each element in this period took up as much as 60 to 70 percent of that in a whole year; In leaf, N and Ca contents were the highest while K, P and Mg were the second. Contents of all elements except K in fruit were lower than that in leaf. Under the condition of N 120 mg·L^（-1）, the grapevine had medium shoot growth and the best fruit quality, and the net absorbing amount of each element for one Mu （666.7 m2） was ： Ca：29.40 kg, N： 18.35 kg, K： 15.42 kg, Mg：4.97 kg, P：1.76 kg, Fe：106.87 g, B：32.76 g, Mn：19.73 g, Cu：ll.10 g, Zn：9.78 g and water：210.97 m^3. [Conclusion] The results can be used as a reference for fertilization and irrigation in vineyard and fertilizer development for grape.关键词
