不同配方栽培基质对盆栽蓝莓生长的影响

Effects of pH and dosages of montmorillonite on the carbon,nitrogen,phosphorus and heavy metals adsorption from biogas slurry

为节省栽培成本、方便本地取材,筛选出可用于盆栽蓝莓产业化生产的栽培基质,将巴尔德温和安娜两个蓝莓品种分别栽培在3种栽培基质[田园土∶花生壳(1∶1)、园土∶花生壳∶草炭(1∶1∶1)、园土∶草炭(1∶3)],并在不同时期对蓝莓生长量、开花结实情况、物候期进行观察测定。结果表明,田园土∶花生壳(1∶1)具有容重适中、气水比较高等特点,更符合盆栽蓝莓的生长需求;经盆栽试验,在株型、生长量、开花结实率、果品质量方面的性状表现均优于其他两种基质;两个品种相比,巴尔德温结实率更高,果实较大,最大单粒重可达2.544g,果实品味较好。综合来说,在广东地区种植盆栽蓝莓,品种选择巴尔德温,使用田园土∶花生壳(1∶1)栽培基质的效果较好。

In order to save the cultivation cost and select the local cultural substrate for industrial production of potted blueberries in Guangdong, mixed matrix of three different blended formulas was designed for this study: soil∶peanut shell (1∶1); soil∶ peanut shell∶ peat (1∶1∶1) soil∶ peat (1∶1 ) . The two blueberry varieties Baldwin and Anna were cultivated in three cultivation substrates respectively. The data of growth, flowering, phenology of bluebarries were collected in different growing stages. The results showed that, soil∶peanut shell (1 ∶1) had the characteristics of moderate bulk density and high gas-water content, which was more in line with the growth requirements of potted blueberries. The potted plants showed better traits in plant type, growth, flowering rate and fruit quality than the other two substrates. Compared with the two varieties, Baldwin has a higher seed setting rate, larger fruit, maximum single grain weight of 2.544 g, and good fruit taste. In general, Baldwin plants in soil∶ peanut shell (11∶1) is the best combination for potted production in Guangdong.
