The principle of the arrangement of greenhouse vegetables

    The principle of planting crops and cornices in solar greenhouses is highly desirable and possible. The so-called possibility, first of all, the warm light conditions created by the built-in daylight greenhouse can meet the fertility requirements of certain crops in specific production seasons: secondly, they basically understand and master the relevant production technology with the producers: the third is to facilitate the rotation and Prevent disease. The so-called needs, first, market demand, there are stable and reliable sales channels; second, the economic benefits are good, but the producers get relatively satisfactory economic income.

 

(1) Arranging crops and mouthwash according to facility conditions

 

The solar greenhouses of different configurations have different temperature and light properties, and the solar greenhouses of the same configuration have different temperature and light performances in different regions. According to the warm light conditions that can be created by the built solar greenhouse, it is the key to achieving high cultivation efficiency. In the solar greenhouse with superior temperature and light conditions, it is advisable to arrange winter and spring vegetable production. For those solar greenhouses where the structure is not reasonable, the indoor minimum temperature is often lower than 8 °C, and the temperature is usually below 3 °C, it is not suitable for use. For the production of winter, spring, cucumber and other warm fruits and vegetables, it is advisable to carry out cold and leafy vegetables such as autumn and winter leeks, and produce warm fruits and vegetables in early spring.

 

(2) Arranging crops and mouthwash according to the market

 

Fresh food production is a very commodity industry, and its efficiency depends first and foremost on market demand. To use the market economy lever to adjust the planting structure, there must be market information and analysis and forecast, not only the local market, but also the trend of the national vegetable market. The demand of the market is frequent and diverse, but the production of solar greenhouses should be professionalized in the direction of regionalization, which is not only conducive to the provision of technical level, but also makes it easier for products to establish stable and reliable sales channels. Therefore, the production arrangements specific to one village and one household should also be coordinated with regional industrial production.

 

(3) Conducive to the rotation

 

The relatively stable land occupation of the solar greenhouse makes the continuous cropping obstacle inevitable. When arranging crops and picking up, it is necessary to help the crops to fall down. For those vegetables that avoid continuous cropping, it is necessary to pay attention to the arrangement of the mouthwash. Not only is the same vegetable being harmful, but the same type of vegetable is also harmful. The onion and garlic vegetables are harmful to most fruits and vegetables.

 

(4) Arranging crops and sputum from the stable production, harvest and harvest

 

Due to the constraints of natural conditions, solar greenhouses are susceptible to natural disasters. Especially in Henan in the Huang-Huai-Hai area, there are many cloudy days in the winter, the light is weak, and the cold weather is easy to reduce the production of greenhouse vegetables. Therefore, in our province, the production of fruit vegetables and winter leafy vegetables in spring and autumn is the most insurance, and it is easy to obtain high yield and stable income.

 

(5) Arranging mouths according to their existing production techniques and conditions

 

Vegetable production in solar greenhouses is a technology, labor and capital-intensive industry. The quality, skills and funds of producers have certain requirements. It is necessary to choose the mouthwash and variety according to their own technical level and capital investment ability. Farmers with high technology and sufficient funds can plant high-grade varieties and wintering cultivation; farmers with low technical level and insufficient input can choose leafy vegetables for production, and then accumulate certain technologies and savings before making high-efficiency production.
