项目摘要

本研究では、川崎市、多摩市、稲城市において慣行農業（６箇所）と環境保全型農業（６箇所）でナシ‘幸水’を栽培するナシ園地でそれぞれ土壌を採取し、都市農業であるナシ生産現場で持続可能な資源循環型農業システムを実現するために土壌分析・調査を実施した。①ナシ園地とその周辺の畑地において、コンペネトロメータによる貫入抵抗・コーン指数を測定したところ、ナシ園地では、深さ０cm～１３cm程度に緻密層が形成されていた。この原因として、ナシ園地は畑地と比較して、耕起の頻度が少ないこと、栽培期間中に多い月には数回スピードスプレヤーによる薬剤散布が実施されることや、観光園地では観光客の踏圧によって土壌が圧密を受ける機会が多いことがその要因と考えられた。②環境保全型農業でニホンナシを栽培した土壌は、慣行農業と比較して、土壌の化学性においては、全炭素量が有意に大きかった。同様に、土壌の生物性においては総細菌数が多く、窒素循環活性が活発であった。③環境保全型農業でニホンナシを栽培した果実の収穫量、糖度、乾物重、果実乾物率は、慣行農業と比較して、同程度であった。

In this study, farmers in rural areas, Kawasaki, Tama, and rural areas are engaged in environmental protection agriculture (6-year institute). In this study, farmers in the cities of Kawasaki, Tama and Tama, rural areas, Kawasaki, Tama, and urban cities are engaged in environmental protection agriculture (6-year institute). In this study, farmers, Kawasaki, Tama, Tama, and urban farmers are engaged in environmental protection agriculture (6-year institute), environmental protection-type agriculture (6-year-old institute), environmental protection-type agriculture (6-year-old institute), environmental protection-type agriculture (6-year-old institute), environmental protection-type agriculture (6-year-old institute), environmental protection-type agriculture (6-year-old institute) 1. Measure the resistance index to determine the degree of 0cm~13cm, the degree of density, the degree of depth, the degree of density, the degree of density, the index of resistance. The reason for this is that the reason is different, that is, the cultivated land is less, and the cultivation period is more than one month. During the cultivation period, there are several times in the cultivation period, and so on. In the middle of the cultivation period, there are several times during the cultivation period. (2) the cultivation of environmental conservation agricultural fertilizer, the cultivation of soil fertilizer, the chemical fertilizer of soil fertilizer, and the concentration of total carbon is intended to increase the production of soil fertilizer. The biological activity of asphyxiate was higher than that of asphyxiator. the results showed that the number of bacteria was high and asphyxiate was active. (3) the environmental conservation type of agricultural crops, such as grain yield, sugar content, dry matter weight, dry matter content, dry matter rate, agricultural grain yield, and the same degree of grain consumption, in the cultivation of environmental conservation agricultural crops.
