Three soybean production increase measures
1. Root off the edge. The more soybean roots, the greater the area that absorbs nutrients in the soil, and the more beneficial it is to increase production. For this reason, the method of cutting off the roots can be adopted to promote multiple secondary roots. The specific method is: When the seedlings grow two opposite leaves, with a spatula 6 cm away from the bean tree and the ground at an angle of 60 incision, cut off the lateral roots and the main root. In this operation, one should pay attention to cutting off the root properly, that is, trimming is indeed cut off the root, while the other side can not be too damaged, in order to facilitate the rapid slow seedling; Second, pay attention to the incision is not large, or easy to wet wet, produce The secondary root is slow and cannot reach the goal. The incision should be pressed properly; three should pay attention to the incision not too deep, do not dig beans. Correct application of this method can increase soybean production by about 12.7%. 2. Twice to top. Some soybean varieties naturally branch not more than 3, in order to promote multi-branching, branching into branches and increasing the yield of individual plants, to be topped. That is, when the seedlings cut off the roots for 3-5 days, wait until the two opposite leaves grow to the top, from the base of the compound leaves will go to the top to promote its four branches, this is a topping; the second topping is in the soybean grows to 1 At the time of rice, as the vegetative growth is too fast, if you do not control the height, if you grow your own length, the growth of the lower stems and roots will be limited, and you will not be able to produce pods and reduce production. Control 1 time. When applying this technique, it should be noted that: once the top is to be "small", the second top should be "old" (that is, hit the top). After topping, due to the inertia of plant growth, it is still possible to “hardly pull up†about 30 centimeters, reaching a normal high yield of 1.3 meters. Correct use of this method can increase soybean production by 14.7%-21.2%. 3. Clever application of fertilizer. Soybean needs special molybdenum, if the soil supply is insufficient, it will grow poorly, the photosynthetic efficiency will decrease, the plants will become shorter, and the yield will be greatly reduced. Production is usually molybdenum seed dressing and extra-root spray, the artificial increase in the amount of acres of standard: 1 kg of seed dressing, spraying 2 kg of roots, the best period of supplemental spraying before and after the end of the season is better. Seedlings to anthesis with plant power 2003 and spraying Baogen outside spray 2-3 times. This method can increase soybean production by more than 10%.
