In the process of planting soybean, if it is not pruned in time and reasonably, the branches of the claw will grow very large and become very miscellaneous, and the branches and vines inside the claw plant will block the light from each other. The flower bud differentiation of pod lateral branches also decreased, the flowering rate and pod setting rate were low, the yield in the middle and late stages was low, and the stubble grabbing was serious in the high temperature period, which eventually led to the decrease of pod yield. In the pod, the side that is too close to the ground needs to be removed in time. Because the pods are long, the pods that grow under plants touch the ground and are particularly vulnerable to underground pests or diseases. Not only that, the lateral buds at the lower part of the pod grow too much, which will also take away some nutrients of Zhu Jiazhi and affect his growth. Therefore, if the lower bud grows to 2-3 cm, it should be smeared immediately. This can improve the ventilation transparency at the bottom of pod plants and speed up the flowering time of pods.

Pay attention to picking branches and handling side branches during pod water period. In the axil of the middle and upper part of the pod main bay, when the flowers grow with the leaf buds, the lateral branches of the pod leaf buds should be removed. If only leaf buds germinate in the axils of the middle and upper leaves of Zhuwan, you can wait until two leaves grow on the side branches of beans. Picking can also promote pod growth, increase bud number and improve fruit setting rate. On the center of soybean horn stock price index: when the stock price index is long on the steel wire, it should be taken over in time. This will help to control plant growth, increase the number of lateral branches, promote the differentiation of flower buds of lateral branches and increase the number of pods. Plant adjustment can generally be collected by the following methods: universal beans should be inserted in time to attract vines. When the plant begins to grow 5-6 leaves, it is necessary to insert a "human"-shaped frame with a bamboo pole, one for each blood. When the plant is more than 30 cm long, drag the vine to the shelf in time to avoid breaking the soft hair of the vine at noon or afternoon on a sunny day.

Zhu Wanchang 15~20 knots, when it reaches 2~2.3 meters high, is helpful to promote the formation and development of flower buds in inflorescences in late summer and to harvest pods. The pruning method of delaying the autumn harvest of pods in plastic greenhouse is basically the same, except that Zhu Wan picked the heart a little earlier, usually when the nectar is 2 meters long. Because, even if the flowers that bloom later can be used as pods, the environmental conditions for growth are not suitable and the goods are not mature. If the heart is picked early, some inflorescences can be removed to reduce nutrient consumption. The lateral bent stems germinated below the first inflorescence of soybean horn were all cut off when they grew to 3 ~ 4 cm. Generally speaking, the lateral direction of 50 cm from the ground can ensure the vigorous growth of Jumana radish, strengthen Zhu Wan's stem and promote the flowering pods in Zhu Shu.

The lateral branches above the pod 1 inflorescence germinated 1 leafy stems, and the main stems germinated 2-3 leafy stems in the middle and late stage. The main stem becomes thicker, which promotes the flowering of the main comic book and the formation of lateral branches 1 inflorescence. Fruit pods produced by lateral branches. After the first peak of pod production, lateral branches will also occur at the flowering nodes 60 ~ 100 cm away from the top of the plant, and the newly sprouted lateral branches between leaf axils will also leave 1~3 hearts, and the leaf yield will keep lateral flowers according to the density. Every inflorescence of soybean has Zhu Huashun and hatching Shun. Usually, under the conditions of development, flowering, pod setting and good nutrition, the incubation books of each inflorescence develop, bloom and pod setting in turn. Therefore, climbing the main vine (about 15 ~ 20 knots, or the main branch is on the iron wire) on the whole frame is helpful to control the plant growth, increase the number of lateral branches, promote the differentiation of lateral branches flower buds and increase the number of pods.
