Xiaochun Broad Bean Field Management

Farmers often say: "three minutes, seven points," which shows that "the species is the foundation, the management is the key." To achieve high yields of broad beans, field management is a major measure. After timely sowing of broad bean seedlings, the soil should be kept moist, especially the water requirement of broad bean during flowering and maturity. In case of drought, it is necessary to timely irrigation, supplement water, so that the soil moisture content is maintained at 25% to 30%. At the same time, it should prevent the accumulation of water in the fields and open the drainage ditch. Timely pruning timely pruning can improve the structure of the population, promote early growth of branches, increase the proportion of early growth, reduce the shade of the field, enhance ventilation and light transmission, improve the nutritional supply of buds, flowers, and pods. The following three steps should be followed in the trimming technique of the spring bean seedlings: The young seedlings grow to the 4 to 5 leaf stage, and the growing point at the top of the main stem is removed to transfer the nutrients to the lateral branches. Promote early onset of branches, thick stalks, not leggy. Pruning When the flowering branches in the field reach more than 90%, ineffective branches and weak branches are destroyed, ventilation and light transmission are improved, and the buds, flowers, and pods of the strong branches are fed to increase the yield. At the late stage of flowering and scabbing, the tipping beats 1 heart at the top of each branch to promote nutrient supply to soybean meal, increase the number of solid grains per plant, increase the grain weight per plant, increase the yield per mu, and at the same time mature earlier. Timely dressing of broad beans is a crop that requires a lot of fertilizers, and increasing nitrogen, phosphorus, and potassium fertilizers have obvious effect on yield increase. Seedlings grow to the 3-leaf stage, with 4 to 5 kilograms of urea per acre to water; until the flowering stage, due to faba bean flowering and scarring need to consume a lot of nutrients, 0.2% concentration of potassium dihydrogen phosphate can be used outside the top dressing, Increase production by about 10%. Diseases and Insect Pests Control of diseases and insect pests such as rust, maggots, etc. of faba bean should be promptly prevented and controlled. Failure to pay attention to prevention and control will result in severe reductions in yields and even in the event of no success. Vicia faba rust, sprayed with 500-800 times per acre with powder rust; broad bean worms, with anti-Scorpion, quail net, etc., in accordance with the dilution of the pharmaceutical instructions to water spray.
