Uniform planting and High-yield cultivation techniques of Soybean
The main results are as follows: 1. the planting density, row spacing and plant spacing are determined according to the plant type and branching characteristics of the variety. The main stem type varieties of ① with dwarf, precocious and anti-nephew branching: row spacing 30-40 cm, plant spacing 8-10 cm, seedling density 1.8-25000 plants. 2. the planting density is determined by the level of soil fertility and management level. After the planting row spacing is determined according to the variety, the density should be adjusted according to the soil fertility and the level of water and fertilizer management. 3. Sow as early as you can. Early sowing can significantly increase yield and fat content, generally at 6.

Daytime management technology of soybean
1. Seedling as early as possible. The peasant proverb says, "if the seedlings are an inch earlier, there will be a crop of dung on top." Interseedling is particularly important for mechanical strip sowing or big ploughing to plant peas. If the distribution of seedlings is uniform and reasonable, the phenomenon of seedling bullying can be prevented in time, which can reduce the consumption of soil nutrients and water, make the development of seedlings balanced and healthy, so as to increase the yield of soybean. The interseedling is generally carried out in the period of two opposite single leaves spreading and compound leaves appearing in the seedling stage of soybean. Diseased seedlings, weak seedlings, seedlings and miscellaneous seedlings should be removed between seedlings. 2. Ploughing and weeding. Generally required to achieve three shovels and three boring. Specific time:

Propagation of improved varieties of soybean
Soybean is a self-pollinating crop, which often becomes worse due to mechanical mixing, bad climate and cultivation conditions, as well as natural hybridization and other reasons. Therefore, self-bred seeds should not be used for a long time and should be replaced every three years. Therefore, we must persist in purification and rejuvenation and do a good job in breeding in order to maintain the breed character of fine varieties. 1. Methods of purification and rejuvenation of soybean varieties (1) selection of strains the common methods of purification and rejuvenation of soybean are composed of three steps: single plant selection, strain identification and mixed high-fold propagation. Separate individual plant selection nursery,

Causes and control countermeasures of sclerotia in soybean
The main results were as follows: 1. The symptom field showed that the upper leaves of the plant became brown and died first, and the stem of the diseased plant continued to develop brown disease spots, resulting in white cotton flocculent mycelium and white particles, and then turned black to become sclerotia. In the stem of the longitudinal dissection plant, there were black cylindrical sclerotia arranged in turn. The diseased plant is gray-white after death, the hollow cortex of the stem is often rotten into hemp silk, and the sclerotia outside the diseased plant is easy to fall off. The disease spot on the pod is brown, it dies quickly and cannot bear fruit, and finally the whole pod is pale. Although the mildly diseased pod can be grained, the diseased grain is rotten or.

Key points of reasonable harvesting methods of soybean
Soybeans should be harvested in time after ripening. If the pods lose too much water in the late harvest, it is easy to explode the pods and cause losses. The suitable harvest time should be determined according to different harvest methods. Those harvested with a sickle begin to harvest after all the soybean leaves have fallen off, and the nutrients have basically stopped being transported to the grains. Mechanical harvesting must be harvested after the whole plant is fully mature and dried. Manual harvesting is best carried out in the morning, when the bean plant has more water content, does not stick in the hand, and is not easy to explode pods. It is required to cut the stubble low, do not show the horse's ears, and do not miss the cutting.

The root of soybean
The root system of soybean belongs to straight root. It can be divided into main root and lateral root, both of which have dense root hairs. The main part of the root is 5-20 cm in the soil, and the whole root system is approximately bell-shaped. There is symbiosis between rhizobium and soybean on soybean root. When soybean sprouts, rhizobium invades the root. When soybean grows the first compound leaf, root nodule is formed on soybean root, first is the main root, and then gradually spreads to lateral root. Nodules are produced by rod-shaped rhizobia with 1-2 flagella at one end. It is a kind of aerobic bacteria, which mainly lives near the earth.

High-yielding cultivation of soybean with large ridge, narrow row and close planting
Large ridge and narrow row dense planting of soybean can increase canopy leaf index, make full use of light energy and achieve the purpose of increasing yield. (1) selection and preparation of land. Wheat, corn or potato are the best in the previous crop. Ridges with sowing. The ridge distance is 130 cm, the ridge height is 25 cm, and the width on the ridge is 30 cm. (2) selection of varieties. The selection of soybean varieties with large ridge and narrow row should be 168,9409B, ZOQI, Fengshou 544, Miyuwang, Hefeng 25, he 93-BS and so on.

Identification and control techniques of soybean downy mildew
Downy mildew occurs more frequently in soybean producing areas in China, especially in northeast and north China during the soybean growth period, and the disease aggravates in rainy years, which seriously leads to premature fall or withering of leaves, mildew of seeds and a reduction of 30% to 50%. It is mainly harmful to leaves, pods and beans of seedlings or adult plants. The pathogens on the diseased seeds caused the disease of the seedlings by systematic infection, but the cotyledons did not show symptoms. When the first pair of true leaves unfolds, chlorotic patches appear along both sides of the leaf veins and expand along the main veins and lateral veins. Cause the whole leaf to fade, there are
