In order to obtain a stable yield of more than 250 kilograms per mu, it is necessary to create a long-term outlook for "a year ago, a year later, a year later, a flowering year, and a lower knot". There are several techniques that should be taken into account during the winter training process.

First, clear root seedlings, loosing soil. For broad bean seedlings that grow too deeply or grow weakly, the surrounding soil must be opened at a proper time so that the leaf segments of the broad beans can be exposed to the outside to stimulate the early emergence of new shoots of broad bean. Before the arrival of the cold, it was cultivated in combination with cultivator loose soil.

Second, Qinggou prevent stains, light Miaofei. In the wetter winter areas, we must dug well the ditch, open the gutter as soon as possible, and constantly clear the ditch, in order to ensure that the gutters are connected and drainage is smooth so as to reduce the waterlogging of the latent layer. In case of dry years, it is necessary to apply water and drought resistance. Generally, the amount of water in the field is about 60%. Vicia faba is a leguminous crop, but before the formation of rhizobia, the root system of soybean plants must absorb nutrients to grow bacteria. Therefore, the base fertilizer is insufficient. Or late broad bean, per acre seedling period topdressing ammonium bicarbonate 5-7.5 kg, prompting long leaf, more rooting, in order to facilitate Rhizobium rapid reproduction and growth.

Third, knock down the main stem to increase nutrient utilization. This is an effective measure to control the main stems, preserve branches, and promote control and integration. For weak growth, grow thin faba bean seedlings, only playing the main stem heart; timely sowing, growth of normal broad bean seedlings, in the seedling height 16 cm, leaves 7-10 pieces, cut off the entire main stem, the growth of Wang's broad bean seedlings, before and after the “winter solstice”, when the plant height exceeds 20 centimeters, the main stem and some large branches are destroyed, and the main stem and large branches should be cut to the seedlings that are planted too early and the seedlings are particularly prosperous. Drop, control the top edge. For slender and weak seedlings, the main stem may be hit or missed.

Fourth, control locusts to reduce diseases. Encountered a warm winter locust damage, so that the top leaf curling affect the growth, optional field fast kill the enemy, killing cricket net, etc. 1000 times liquid spray treatment. After the aphid is harmed, it can cause virus disease in broad beans and make the plants dwarf or rigid. Therefore, in the early winter, the prevention and control of aphids can reduce the incidence of spring bean virus disease.
