Berries are distributed all over the world, mainly in areas with cool climate and abundant sunshine, such as Japan, North Korea, Europe and North America. The main planting areas in China are Liaoning, Heilongjiang, Jilin and other areas, and there are many wild varieties in Daxing 'anling. These wild varieties are rare, and the price is several times that of artificial cultivation. Blueberries in North America are world-famous. They grow in temperate zone and cold zone, and their import value in China reaches 100-200 yuan Jin. To sum up, blueberries are suitable for planting in the cool northern region, but not in the hot southern environment.
1. 1 input-output theory
In economics, factors of production can be generally divided into four categories: labor, land, capital and entrepreneurial talents. Labor usually refers to human labor that can output labor quantity or labor value, and it is a means for people to maintain their own survival and self-development. Land not only refers to the land itself, but also includes the land part of the earth's surface and all available natural resources in a certain range of space above and below it. Capital refers to the basic elements used in production, that is, capital, plant, equipment, materials and other material resources. Entrepreneurial ability refers to the organizational ability, management ability and innovation ability of entrepreneurs to run enterprises.
Production function refers to the relationship between the quantity of various production factors used in production and the large output that can be produced in a certain period of time under the condition of constant technical level.
1.2 Cost Analysis of Blueberry Planting Enterprises
The costs of large blueberry planting enterprises include establishment costs, scientific research costs, planting costs, operating costs, management costs, processing costs and sales costs. The costs of ordinary and small blueberry planting enterprises mainly include establishment costs, operation costs, management costs, processing costs and sales costs. The cost of small-scale blueberry planting enterprises is discussed below.
1.2. 1? construction cost
Establishment expenses refer to some necessary expenses incurred by blueberry planting enterprises before their establishment. For example, land selection fee, rent, soil improvement fee (blueberries are suitable for growing in acidic soil, with a general ph value of 4-5), seedling purchase fee, digging and cultivation fee, irrigation fee (blueberries can neither be dry nor waterlogged, so it is best to use drip irrigation technology during their growth), tools used in the production process (such as shovels) purchase fee, salaries of relevant personnel in base construction, and so on. Among them, rent, soil improvement fee, seedling purchase fee and irrigation fee are the main costs.
1.2.2 Operating costs
Operating cost refers to the cost paid by blueberry planting enterprises to maintain normal operation under the condition of being built. Such as: the labor cost of weeding and catching insects for blueberries to maintain their normal growth, the labor cost of letting them absorb enough nutrients by farm manure, the picking cost of blueberries when they are ripe, the storage cost of related tools, and the garden care cost.
