Luohan beans planting time: the end of October to early-mid November each year, the following spring and summer harvest. Get sowing method: 1. Seedling management: broad bean is a deep-rooted crop, fine ground preparation before sowing, can make the soil loose, conducive to the expansion of the root system and the formation of rhizoma. In the seedling period according to the seedling situation to control water or irrigation to achieve pier strong seedlings, so that seedling Qi, seedling uniformity, seedling strong, glue dip mud bean field, after sowing should be timely covered with grass insulation and moisturizing. 2. medium-term management: do a good job in predicting the forecast of diseases and pests, timely prevention and control of pests and diseases, grass and rodent hazards, do a good job of water management, field rectification of interseedling, pulling out the thin and weak plants and diseased plants, to ensure that the group grows healthily. 3. late management: to ensure that the filling period on the Water demand, so that the soil moisture content to maintain at 20-25%, less than 18-20%, must be immediately irrigated, high-yield fields and late maturing fields, the final flower dispersal of the tip of the period for the top of the picking core, conducive to ventilation and light, increase grain weight, and promote precocious maturity. 4. Reasonable fertilization: after sowing mu cover high-quality stable fertilizer 1500-2000 kg / mu or cover the appropriate amount of straw, in the bean seedling 2.5-3 Taiwan leaves period of application of calcium 30 kg / mu, potassium sulphate 10-2000 kg / mu. Mu, potassium sulfate 10-15 kg / mu. 5. drought and flood prevention: broad beans are very sensitive to water, both afraid of drought and flooding, if the field drainage is poor, the root system is poorly developed, and prone to blight and rust, such as in the event of a drought, especially the flowering of the pods period, the impact on the yield of the more serious. Therefore, according to the growth needs, timely drainage and irrigation to ensure a good harvest. 6. timely harvest: broad bean maturity, since the lower pods. If harvested green beans for vegetables, can be bottom-up 3 to 4 times harvested. If the harvesting of old mature seeds, should wait for the majority of plants in the lower part of the pods blackened once harvested. After harvesting the fresh broad bean seedlings should be turned composted in a timely manner to maintain nutrients.
