1. Field selection and site preparation fertilization. Planting broad beans should be done with a good water permeability, a low groundwater level, and soil with loamy soil and sandy loam soil. Drainage and irrigation are convenient. Before sowing, 1500-2000 kg of fertilizer and 60 kg of phosphate fertilizer are applied per mu, and then the ploughs are used for site preparation.
2, sowing date and sowing specifications. The anti-season broad bean sowing season in the mountainous area is from July to August. Sowing specifications 2010cm, 3.3-3.5 million basic seedlings per mu.
3, variety applications. Variety using local small beans, Fengdou 4, Fengdou 5 and so on.
4, take agricultural industry measures to prevent and treat diseases. The major diseases of broad bean include root rot, rust, and red spot disease. There is a very close relationship between the onset and the environmental conditions. Therefore, adopting timely sowing, establishing a field irrigation and drainage system, reducing groundwater level, rotating crops, increasing organic manure, and combining nitrogen, phosphorus and potassium with agricultural measures are effective measures to control and reduce the occurrence of broad bean diseases.
5, field management. (1) Weeding. Herbicide can be used to kill grass weeds, legume weeds need to be manually removed; (2) topping. Remove the bean tip when 5-6 leaves, increase the effective branching and scab volume; (3) hit the bean tip. After the faba bean has reached full flowering stage, the tip of the bean can be hit and the length is cut off by 15-20 cm. This increases the permeability of the field in the right, promotes full grain filling and reduces pest damage. (4) spray boron and molybdenum mixture. From the beginning of flowering to the full flowering period, spraying with 2% ammonium molybdate plus 5% borax can play a role in protecting the flower, keeping the soil, keeping the grain, and increasing the grain number. (5) Pest control. Broad bean diseases are mainly root rot, rust, red spot, and blight, and pests mainly include aphids and spotted flies. Early detection and early control should be done, and any pesticides should be banned 40 days before picking.
