The principle of planting crops and cornices in solar greenhouses is a need and may be highly uniform. The so-called possibility, first of all, is that the sunlight and sunlight conditions created by Sunlight Greenhouse can meet the fertility requirements of certain crops during specific production seasons: Secondly, they basically understand and master the relevant production technologies with producers: The third is to facilitate rotation and Prevent disease. The so-called needs, one is the market demand, there are stable and reliable sales channels; the second is good economic returns, but producers get relatively satisfactory economic income.
(a) Arrange crops and cornices according to the conditions of the facility
Solar greenhouses with different configurations have different temperature and light performances. Solar greenhouses with the same configuration have different temperature and light performances in different regions. Planting crops and cultivating crops according to the lukewarm conditions that can be created in the established solar greenhouses is the key to achieving high cultivation efficiency. Solar greenhouses with superior temperature and light conditions should be suitable for the production of winter and spring vegetables and greenhouses. For those greenhouses that have unreasonable structures, indoor minimum temperatures often fall below 8°C, and temperatures below 3°C usually occur, they should not be used. For the winter and spring production of cucumbers and other thermophilic fruit and vegetable production, it is advisable to produce cold-tolerant leafy vegetables such as autumn and winter leeks, and to produce warm and fruity vegetables in early spring.
(b) According to the market arrangement of crops and cornices
The production of fresh vegetables is a very strong commodity industry, and its level of profit depends primarily on market demand. Using market economic leverage to adjust the planting structure must have market information and analysis and prediction, not only depends on the local market, but also on the trend of the national vegetable market. The market demand is frequent and diverse, but the production of solar greenhouses should be developed towards the regionalization of specialization. This will not only help provide technical level, but also make it easier for the products to establish stable and reliable sales channels. Therefore, specific production arrangements for a village or a village should also be coordinated with regional industrial production.
(c) It is conducive to taking turns
The relative stability of the solar greenhouse covers an inevitable obstacle to continuous cropping. When arranging for planting crops and picking up crops, it must be conducive to crop rotation. For those vegetables that are not allowed to make continuous cropping, it is even more necessary to pay attention to the arrangement of cornices. Not only does the same kind of vegetable work as harmful, but it is also harmful if the same kind of vegetable is used together with one family. Precursor vegetables are harmful to most fruit vegetables.
(D) To arrange crops and cornices from the benefits of stable production and yield
Solar greenhouses are easily affected by natural disasters due to the constraints of natural conditions. Especially in Henan in the Huang-Huai-Hai region, the winter continues to be cloudy for many days, and the light is weak. In addition, the cold and cold weather all make it easier to reduce the production of solar greenhouse vegetable production. Therefore, in our province, the production of fruit and vegetables and wintering leafy vegetables in the spring and autumn seasons is the most secure, and it is easy to obtain high yields and stable incomes.
(v) Arrangements should be made according to their existing production technology and conditions
Solar greenhouse vegetable production is a technology, labor, and capital-intensive industry. The quality, skills, and funding of producers all have certain requirements. According to their own technical level and capital investment ability to choose gargle and varieties. Farmers with high technology and sufficient funds may plant high-grade varieties and overwintering cultivation. Farmers with low technological level and insufficient investment may choose to use leafy vegetables for production, and then accumulate certain technologies and savings before making cost-effective production.
