大面积的花卉繁种不同于园林部门的生产,它是农业产业化的一部分,是对我国农村丰富的土地资源和气候资源的开发利用。繁种的成败不以培育出的花卉的观赏性状为标准,而是种子的产量、质量及成本高低决定的。本文主要介绍一二年生草花自交繁种的步骤和方法。一、繁种基地的选择必须根据所繁花卉原产地的气候和其生长条件,确定基地的大致范围。这就需要具备一定的地理及气象知识,了解全国各地气候类型、土壤状况及自然灾害发生情况等,然后实地考察,确定地点。 1.气象资料的收集。有利的气候条件,既可降低成本又可保证繁种工作顺利进行。因此,需要到当地气象
The large area of flower species is different from the production of the garden sector. It is part of the industrialization of agriculture and is the development and utilization of the rich land resources and climate resources in rural China. The success or failure of breeding is not based on the ornamental traits of cultivated flowers, but on the yield, quality and cost of the seed. This article mainly introduces the steps and methods of one-year-old grass flower self-bred. First, the choice of breeding base must be based on the flowers of the climate and its growing conditions of origin, to determine the approximate scope of the base. This requires knowledge of geography and weather to understand the types of climate, soil conditions and the occurrence of natural disasters in various parts of the country, and then to conduct site visits to determine the location. 1. Meteorological data collection. The favorable climatic conditions can not only reduce the cost but also ensure the smooth progress of breeding work. Therefore, the need to local weather
