(1) Temperature: Vicia faba is native to temperate climates. It is a warm and humid climate. It does not endure heat and cold. It is also worse than wheat, barley, and peas. The optimum temperature for faba bean germination is 16 degrees Celsius, the maximum temperature is 25 to 35 degrees, and the minimum temperature is 3.8 degrees. When the seedlings meet the temperature of minus 4 degrees Celsius, the leaves can be frozen, and the top of the stems withered from minus 5 to minus 7 degrees will die. However, different temperature requirements for different growth periods are different. The temperature needed during the vegetative growth period is relatively low, and the optimum temperature for the vegetative organs is 14 to 16 degrees Celsius. When the temperature is high, the plants are short and have few branches, and they are easy to flower in advance. Flowering and podling require higher temperatures, and the optimum temperature for the formation of reproductive organs and flowering and scarring is 15 to 20 degrees Celsius. If the temperature is too low, pollination is not normal and there is less scarring. (2) Moisture: Wet growth of broad beans, avoid drought, fear of waterlogging. Vicia faba seed coat thicker, the seed germination to absorb the equivalent of the seed's own weight of 100 to 200 percent of the water, so sowing to seedlings to keep the soil moist, in order to facilitate seed germination emergence. After emergence, the soil is kept moist, which favors the development of roots and is robust and robust. During the flowering stage, more water is needed and the soil should be kept moist. To grow broad beans in the southern paddy fields must be done in time and work well. (3) Vicia faba is a long-day crop that is happy with light. The northern species and southern introduction are delayed and late. They only use false or small grains. The North Seed Breeding of South Seed shows early precocity and is not cold tolerant. Therefore, the introduction of broad beans should be careful. The response of broad beans to light is intermediate and has a certain degree of adaptability. There are two peak periods in photosynthetic productivity of broad bean, one is in the flowering stage, the other is in grain filling stage. (4) In addition, the soil conditions required for the growth of broad beans are slightly alkaline and fertile, and the soil has a thick clay loam soil, and the soil pH value of 6.2 to 8 is appropriate. It has certain adaptability to the saline-alkali land. According to the test, broad bean can be cultivated on the alkali ground where it is not suitable to grow beans and peas. However, the sodium salt content of 25 to 35 milliequivalents per 100 grams of soil completely inhibited the growth of broad bean, nodule formation, dry weight, and plant nitrogen content. The effect of sodium chloride and sodium carbonate is greater than that of sodium sulfate. (5) Broad bean is also a kind of crop that needs more fertilizer. The flowering period of broad bean is the peak period of fertilizer demand, and also the period when the accumulation of dry matter is the most. According to tests, approximately 150 kg of grain per acre is produced, requiring 9.6 kg of nitrogen, 3 kg of phosphorus, and 7.5 kg of potassium. Vicia faba is symbiotic with Rhizobium, and each rhizobia can fix 5 to 10 kg of nitrogen from the air. In addition, the requirement of trace elements for broad beans is more sensitive to reaction, and in particular boron deficiency should be taken into consideration.
