Technical guidance on Spring sowing of Soybean in Northeast China
In autumn and winter last year, the precipitation in Northeast China was less than usual, the soil moisture was insufficient, and the drought was serious. There is more rain and snow this spring, the temperature has risen rapidly since the beginning of April, and the temperature and precipitation are close to year-round. The soybean expert guidance group of the Ministry of Agriculture and the National Agricultural Technology extension Service Center, on the basis of full investigation, put forward the following technical guidelines for spring sowing of soybean: first, strict selection of excellent varieties due to the dry climate last autumn, soybean harvest may not be physiologically mature, mechanical threshing increases the possibility of seed embryo injury.

The effect of increasing the yield and income of autumn soybeans in rice field is good.
According to the experiment, after the middle rice is harvested, making use of the temperature and light conditions in the field, planting one season of autumn soybean can increase the yield of soybean by 60,120kg / mu and the economic income of 150,420 yuan / mu. It is suitable to be popularized in the regenerated rice areas below 400 meters above sea level. The technical points are as follows: first, the improved varieties of suitable land: the fields with anhydrous storage of recycled rice below 400 meters above sea level and all rice seed fields can be planted. After rice seeds are scattered, ditches are opened for drainage; after rice harvest, weeds and rice stumps are removed in time, not ploughing, and press

Control measures of main diseases of soybean
Soybean mosaic disease the pathogen of soybean mosaic disease is virus, and there is no specific agent at present. The key to the prevention and control of the disease is to control the occurrence, spread and harm of aphids, so as to "cut off the source of poison, control insects and control the disease". In the initial stage of aphid occurrence, timely drug control should be used to control aphids in the early stage of aphid outbreak. 1. Agricultural control: ① popularizes disease-resistant varieties; ② strictly selects seeds and removes brown spots before sowing; ③ establishes non-(low) toxin seed propagation system and healthy seed field. Healthy seeds should be selected in the seed field, and the diseased seedlings should be removed by shoveling before the occurrence of aphids.

Shennong 6 (soybean)
[basic situation] Shennong 6 (original serial number Shennong 91-44) was selected by Department of Agronomy of Shenyang Agricultural University in 1986 with Fengjiao 66-12 as female parent and Kaiyu 8 as male parent. Since Shennong 6 was introduced to Pulandian City in 1996, it has been tested by different years and different climatic conditions (low temperature, low light, high temperature and drought). It has shown high yield, stable yield, disease resistance and lodging resistance, with an average yield increase of 18.7% to 24.7% compared with the control. in order to make Shennong 6 excellent species.

Shandou 125 (soybean)
High quality soybean Shandou 125 is a new soybean variety selected by genealogical method by School of Agriculture, Northwest University of Agriculture and Forestry in 1988. the original line code is 88125-3-7-4. In 1988, So-3-4 was used as female parent and Japanese variety Ri 9-11 as male parent. 21 seeds of F1 generation were harvested in that year. The F1 generation was planted in 1989, which showed early maturity and good disease resistance. After eliminating pseudo-hybrids, 16 plants were harvested neatly and consistently. The F2 generation was planted in 1990, with large separation and type.

How to promote early maturity and high yield of soybean
1. When selecting suitable varieties, the varieties with shorter plant height and sparse planting should be selected. These varieties have relatively less water requirements and less yield loss in dry years. Second, strengthen field management and weeding in time. Weeds compete with soybeans for fertilizer and water, which affects photosynthesis and is not conducive to ventilation, so weeds should be eradicated in time. Shovel at the right time. When shoveling, we should deeply shovel and cultivate more soil to enhance the permeability of the soil and the ability of water and fertilizer conservation. 3. on the basis of the application of farm manure, the amount of chemical fertilizer should not be applied.
