Broad bean field management
1. Weeding and weeding: The first cultivating and weeding is performed when the height of the broad bean seedlings is 10cm, the depth of the pods is 7-10cm, and the depth is 5cm between the cultivars; the second cultivating is performed when the plant height is 15-20cm, and the cultivating depth is about 5cm. Before the stage of pod till maturity, weeding grass was taken 1-2 times depending on the condition of weeds in the field. Timed cultivating can not only eliminate weeds in the field, loosen the soil, but also promote the activity and root development of rhizobia, enhance the activities of soil microorganisms, and have obvious effects on increasing branches. Do not damage the plastic film and infect the broad bean plants during operation. 2. Reasonable irrigation: Broad bean likes warm and moist environment during growing season. Therefore, timely irrigation is one of the key measures to ensure early and high yield of broad bean. When the main stem of broad bean was flooded with 5-6 pieces of compound leaves, the first water was poured, the second water was full of flowering stage, the third water was the stage of the flood season, and the fourth water was in the flood season during the drought year. During the whole growth period, the seed water, bud flowering water, flower blooming water, grain filling water should be filled timely according to the water holding capacity of the field, and the speed of irrigation should be required. 3, the scientific application of top dressing: combined with weather conditions for topdressing, low fertility weak seedlings Mushi urea 0.5-1 kg. Foliage topdressing can be carried out in the middle and late stages (full flowering period - final flowering period) to promote pollen germination, increase pollination rate, reduce flowering and falling, and increase yield. Fertilizers were sprayed with potassium dihydrogen phosphate and Methyl Boron mixture at the flowering stage and flowering stage. radiopaque adhesive tape,Radiopaque Tape,Medical Tape Anesthesia Medical Co., Ltd. , https://www.jssinoanesthesia.com
