In the season of peanut planting, the important factor for the high yield of peanut planting is the rational fertilization. The peanut planting and fertilization should be based on farmyard manure and supplemented by chemical fertilizer. In China, most of the peanuts are planted in hilly areas, with thin soil layers and low fertility. The farmyard manure is mainly organic fertilizer, which is rich in nutrients, which can improve soil, fertilize and fertilize, and has long fertilizer efficiency. Fertilizer is a quick-acting fertilizer. Although it also contains the nutrients needed by peanuts, the nutrients are still single compared with farmyard manure. At the same time, during the application process, other components remain in the fertilizer, which is not conducive to the growth of peanuts and the improvement of soil fertility.
The combination of organic fertilizer and inorganic fertilizer, the interaction between the two, improve the activation of microorganisms in the soil and the decomposition rate of organic fertilizer, and convert various nutrients into peanuts, thereby improving the utilization efficiency of fertilizers. The total amount of nitrogen and potassium is doubled. For each 50 kg of peanut pods produced, the ratio of nitrogen, phosphorus and potassium is required to be 5:4:2.5. The seasonal utilization rates of peanuts for nitrogen, phosphorus and potassium fertilizers were 41.8%~50.4%, 15%~25% and 45%~60%, respectively.

Ventilation is one of the most important components in a successful greenhouse.
If there is no proper ventilation, greenhouses and their growing plants can become prone to problems. The main purposes of ventilation are to regulate the temperature and humidity to the optimal level, and to ensure movement of air and thus prevent build-up of plant pathogens (such as Botrytis cinerea) that prefer still air conditions. Ventilation also ensures a supply of fresh air for photosynthesis and plant respiration, and may enable important pollinators to access the greenhouse crop.
