| 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. |
