一、目的与材料方法 青椒保护地栽培如何更合理地调整个体生育和群体结构,以提高光合量达到增加产量和提高品质,日益受到重视。以日本广泛栽培的中果型‘新魁’为试材,探讨不同的主枝数和诱引角度等整枝方法对提高产量和商品品质的作用,为温室大棚的青椒整枝技术提供依据。 试验在日本国立高知大学农学部试验农场进行,试材为‘新魁’,于1987年3月17日在砂床播种,子叶展开时移植在直径12cm的塑料育苗钵中。4月6日幼苗有4枚叶片时定植在砂床栽培槽中。株行距为60cm×120cm,4月17日开始供给营养液。主枝数目试验区设2、4、8个主枝的3个处理区,各区均以与主茎45度倾斜诱引。在诱引角度试验区,每株留4主枝,诱引角度分为与主茎延长线成30°、60°、90°角。主枝数和诱引角度两试验区均以一个栽培槽为1小区,试验设2次重复。
First, the purpose and methods of material Green pepper cultivation how to more appropriately adjust individual fertility and population structure in order to increase the amount of photosynthesis to increase production and improve quality, more and more attention. In this study, we used the ’New Quebec’, a widely cultivated middle fruit cultivar in Japan, as a test material to explore the effect of pruning methods such as different numbers of main branches and angles of attraction on the yield and quality of products and provide the basis for green pepper pruning in greenhouse. The experiment was carried out on the experimental farm of the Faculty of Agriculture, Kochi University in Japan. The test material was ’New Quebec’. It was sown on a sand bed on March 17, 1987 and transplanted in a plastic nursery bowl with a diameter of 12 cm when the cotyledons were unfolded. April 6 Seedlings have 4 leaves planted in the sand bed cultivation tank. Plant spacing of 60cm × 120cm, April 17 began to supply nutrient solution. Main branch number The experimental area is set to 3 treatment areas of 2, 4 and 8 main branches. Each area is inclined with a 45 degree inclination of the main stem. In the induced angle test area, four main branches per plant were left, and the inducing angle was divided into 30 °, 60 ° and 90 ° angles with the main stem extension line. The main branch number and induced angle of two pilot areas are a cultivation tank for a plot, the trial set two replications.
