In order to obtain stable high yields of 250 kg per mu, faba beans must create the appearance of "year-old branches, flowers after the year, flowering on the top, and pods on the bottom". The following techniques should be grasped in winter tube cultivation.
First, clear root squatting seedlings, loose soil training. For broad bean seedlings that are sown excessively or weakly, the surrounding soil should be removed in a timely manner so that the leaves of the broad bean are exposed to stimulate the early development of new shoots of the broad bean. Before the advent of severe cold, cultivate with soil-cultivating loose soil.
Second, clear ditch to prevent stains, lightly apply seedling fertilizer. In rainy areas in winter, we must excavate surrounding trenches, open waist trenches as early as possible, and constantly clear the trenches, so that the trenches and ditches can be communicated and drained smoothly to reduce the damage of subsurface water. In case of drought, it is necessary to irrigate and fight drought. Generally, the water holding capacity in the field is about 60%. Broad beans are legumes. Or late sowing broad beans, topdressing with 5-7.5 kg of ammonium per mu per seedling stage, to promote fast long leaves and more rooting, in order to facilitate the rapid reproduction and growth of rhizobium.
Third, knock off the main stem and improve nutrient utilization. This is an effective measure to control the main stem, protect the branches, and promote the combination of control. For broad bean seedlings that are not growing vigorously and weakly, only hit the top of the main stem; for broad bean seedlings that are sown in time and normal, when the seedling height is 16 cm and the leaves are 7-10, the entire main stem is cut off. The flourishing broad bean seedlings, before and after the "winter solstice", when the plant height exceeds 20 cm, the main stem and some large branches are destroyed. For fat seedlings that are planted too early and the seedlings are particularly vigorous, the main stem and large branches should be cut off Out, control the top edge. For lean and weak seedlings, the main stem can be hit late or not.
Fourth, control aphids and reduce diseases. When encountering warm winter, there are often aphid hazards, which will cause the parietal leaf to shrink and affect the growth. After aphids are harmed, they can cause broad bean virus disease and make the plants dwarf or die. Therefore, early control of aphids in early winter can reduce the incidence of spring broad bean virus disease.
