油茶开花季节,繁花满枝,然而到了收获季节,它的成果率很低。以安吉县南湖林场为例,45株标准株平均每株开花1155.5朵,而成果的花数只占总开花数的9.3％。分析造成“只见满树花,不见满枝果”的原因很多,如品种、水肥、病虫危害等,但花期气温的高低却是决定油茶产量的主要因子。本文仅从花期气温与产量的关系作一简要分析。
Camellia flowering season, full of flowers, but in the harvest season, its low rate of achievement. Taking Nanhu Forest Farm in Anji County as an example, the average number of 45 standard strains per plant is 1155.5, while the number of flowers per plant only accounts for 9.3% of the total number of flowering. There are many reasons for the analysis such as variety, water and fertilizer, pest and disease, etc. However, the temperature of flowering is the main factor that determines the yield of Camellia oleifera. This article only from the flowering temperature and yield a brief analysis of the relationship.
