The best time to plant broad beans
Generally, spring broad beans in northern and western areas are sown from early March to mid-late April, and autumn broad beans in southern areas are sown in June 5438+ 10. Broad beans are suitable for sowing in the bean planting area at an altitude of 1550- 1700 m from May 5 to June 55438+05, and in the bean planting area at an altitude of 1750- 1900 m on June 0.
Variety selection: In areas with fertile land and high fertilization technology, varieties with fertilizer tolerance and lodging resistance should be selected to give full play to the potential of increasing production. In areas with poor soil and poor fertilization ability, high-yield varieties with wide adaptability and barren tolerance are adopted. Seed treatment: seed treatment is needed before broad beans are sown, and the seeds should be dried for 2 ~ 3 days before sowing to improve the emergence rate.
Matters needing attention
Before sowing, dissolve ammonium molybdate with clear water, mix it with seeds, then mix it with anthrax Fu Mei, mix it now, and sow now. Broad beans like temperature and are not tolerant to waterlogging, so they should be planted on high-quality and well-lit farmland, and choose convenient and fast water sources for irrigation. Then prepare the organic fertilizer with better yield of chemical fertilizer, phosphorus and potassium fertilizer, potassium fertilizer and alcohol in advance, and apply less base fertilizer.
Because broad beans can transform molecular nitrogen in nature into nitrogen-containing chemicals, which can improve the nitrogen content of soil layer. Before sowing, soak the prepared broad bean seeds in warm water until they swell, and then start sowing, so that the seeds can germinate quickly. There are two main inoculation methods before sowing, one is soil inoculation and the other is seed inoculation, which can improve the yield of broad beans.
