The arrangement of cornices in greenhouses must be adapted to the market, adapted to local conditions, and adapted to the conditions of the shed. The following principles should generally be mastered in the arrangement of mouthwash: First, according to the market price, the peak period of vegetable harvest is arranged at the highest price of vegetables. The second is to arrange the ripening period of vegetables in the most suitable season for the growth of vegetables. Only combining high yields and high prices can achieve high benefits, reduce management difficulties and production losses. For example, some vegetable farmers only see the high price of vegetables during the Spring Festival. They do not consider the insulation performance of their greenhouses and blindly carry out the winter production of a large amount of vegetables. Before and after the Spring Festival, it is the season with the weakest sunshine, the shortest sunshine time and the lowest temperature. The low-grade greenhouse insulation performance is poor, it is difficult to meet the needs of vegetable growth, is not conducive to the growth and development of vegetables, the output is extremely low, and often falls short of expectations. Effect. As a matter of fact, greenhouses with poor insulation performance, if they are produced for two years a year, that is, winter and spring and autumn and winter, make full use of the light and heat resources from March to June and September to November to obtain high yield and high efficiency. The third is to increase the utilization of greenhouses. There is a problem of “summer leisure†in winter greenhouses. There is a problem of “wintertime†in arch shelters. Cultivation of straw mushrooms and planting of bean pods during the summer rest period of winter-warm greenhouses can effectively improve the cultivation of canola, spinach, etc. during the winter period. Planting benefits. The fourth is to consider changing crops with other vegetables to reduce pests and diseases and prevent secondary salinization of soil.
