Key Techniques for Growing Edible Broad Beans in Winter Leisure Field

Consumption of broad beans, commonly known as Han beans, Luo Han beans. Rich in protein, starch and various vitamins, it is a good dish on the table like vegetables, peas and green beans. It is also a vegetable that is popular in the off-season vegetable market. The use of winter and field farmed broad bean beans to harvest the tender broad bean supply market in late spring will not affect the planting of early rice in the coming year, but it also has a considerable amount of income. Broad bean called "inert crop", that is to say as long as the seed into the soil there will be harvest. In fact, it is the same as other legumes. In order to achieve high yield, high quality, and high efficiency, it also requires careful management. In terms of cultivation, we must focus on the following five technical measures:
First, the appropriate time for planting broad bean sowing time is "before and after the beginning of winter" 5 days. Before sowing, 667m2 of Datian was applied to decomposed pigs and cows manure 2000-3000kg as base fertilizer, combined with soil preparation. For 畦, 畦 width 1.2 ~ 1.3m; digging hole, hole depth 5 ~ 6cm, hole distance 30 ~ 35cm. Apply superphosphate and potassium chloride into the hole, apply 40-50kg per 667m2, cover soil 2cm thick, then sow, broadcast 2 to 3 capsules per hole, cover soil 3 to 4cm after sowing.
Second, antifreeze insulation Although broad bean cold-resistant crops, but the cold resistance is not very strong. When the temperature in winter is 3 to 4 days at minus 4 to 5°C, the seedlings are susceptible to freezing injury. Therefore, insulation measures should be taken in winter and early spring: 1. For each 667m2 of plant ash 1000 ~ 1500kg, concentrated in the root of plant parts; 2. Overlay between rows with straw or chaff.
Third, the science topdressing broad beans like phosphorus, potash, before flowering combined with cultivator soil topdressing 50 ~ 60kg superphosphate per 667m2, full flowering with 0.2% ~ 0.3% potassium dihydrogen phosphate for foliar fertilizer 2 ~ 3 Times, to facilitate flowering and fruit setting.
Fourth, cultivating soil Vicia faba is a hi-light crop, in order to prevent weeds and broad beans competing for light, in addition to the herbicide before sowing, until the Qimiao after a cultivator, into the spring shallow shit 1 times, combined with topdressing soil before flowering When cultivating cultivators, do not injure the root system as much as possible. 5. The long-blooded faba bean beans have a long flowering period. Their characteristic is that they gradually blossom and scab up from the base of the plant. The stem base of the plant stem has often been given off. The upper part of the stem is still growing and budding and flowering, resulting in a great consumption of nutrients. Not only does it take too much of the stem to grow, it also affects the development of pods at the base of the stem. Therefore, it is a key technical measure for the high-yielding cultivation of broad bean in timely harvesting of the control point. The topping should be carried out at the base of the stem of the plant, when the flowers are scarred, and when the flowers are in the middle. To be carried out in batches in phases, it cannot be “one size fits all” nor should it be too heavy or too light. Excessive weight will impair photosynthesis, and if the accumulation of nutrients in plants is too light, it will not be able to control the strength of the master. Generally each stem from the middle scab site to stay up 3 ~ 5 pairs of leaf topping is appropriate.
