At the time of planting Daejeon, Professor Gong Zhenping of Northeast Agricultural University made suggestions to farmers on this year's soybean production. Buy varieties on demand Prof. Gong said that when farmers choose varieties, if they have orders with soybean processing companies, they should choose varieties that meet the quality requirements of processing companies. Such as high protein, high oil, etc., to improve efficiency. If there is no order, high-yield and disease-resistant varieties can be selected to increase production efficiency. When purchasing varieties, it is necessary to purchase large-scale, well-recognized seed sales departments; certain receipts must be issued for invoices or related certificates for purchasing seeds; varieties should be selected for appropriate ripening periods, and ripening periods should affect yields early, and partial production will result in failure to mature normally. After the seeds are purchased, the germination rate must be tested first, and the high germination rate is beneficial to preserve the seedlings. Drought resistant seedlings Professor Gong Zhenping said that planting seedlings is the basis for high yields. The main problem in achieving this goal is drought-resistant seeding. The land that was prepared in the autumn last year could be planted directly on the wet soil if the soil moisture was good. It was necessary to ensure that the seeds were sown on the wet soil; some of the soil layers were thicker, and some of the dry soil on the roof of the ridge could be used to sow seeds with seeds to ensure seeds. Sowed on wet soil, it will not sow too deep. In order to guarantee seedling emergence, the original plutonium plot should be less groundless and can be treated with stubble treatment and then sown on the original ridge. Do not turn over to the ground in the spring, resulting in the loss of soil water. Soybean meal can also be used to eliminate cockroaches. Can also be used sowing. When it is particularly dry, consider taking water. It is recommended that the ditch be deep and loose. After autumn harvest, before sowing, at the same time as sowing, or at the seedling stage of crops, the ridges and furrows can be deep and loose, and the effect of combining the first squats is the best, because a lot of rainfall can accumulate near the rainy season. In particular, the plot of extinction of the original ridge ridge, the role of the ridge and furrow at the seedling stage is more pronounced. Rational close planting of scientific fertilization Traditional ridge cultivation (65 cm ridge distance), with a density of 250,000 plants per hectare, is suitable for double rows on ridges. That is, the ridge is 10 cm above the ridge, and the spacing is 10-12 cm. In dense planting, the density can reach 450,000 plants/ha. But be sure to choose dwarf rice varieties, otherwise it will lead to lodging. When ridges are planted densely, it is possible to adopt four rows of large ridges or three rows of large ridges. The density of dwarf rice varieties can reach 450,000 plants/ha, and that of conventional plants can reach 250,000 plants/ha. Soybean fertilization should be diammonium 10 kg/mu; potassium sulfate 5~7 10 kg/mu; because soybean root nodulation can generally meet about 60% of soybean total nitrogen requirement, and nitrogen fertilizer will inhibit nodules nitrogen fixation, at present Heilongjiang General Soil fertility conditions, diammonium nitrogen 18%, Mushi diammonium 10 kg, of which the nitrogen can meet the needs of soybean; soil fertility in poor soil can be equipped with 2 kg / mu. When sowing and fertilizing, it is necessary to separate the fertilizer and avoid burning seeds and burning seedlings. Timely control of pests and diseases According to Professor Gong Zhenping, the current common diseases and pests of soybean mainly include soybean root rot, soybean gray spot disease, soybean sclerotinia, sputum, and soybean borer. Root rot is one of the common root rots in soybeans and occurs mainly in the seedling stage. The seed dressings for controlling root rot may be used for seed dressing and have certain control effects. Soybean gray spot mainly damages the leaves and can also infect stems, pods and seeds. Disease-resistant varieties can be used for prevention and treatment. Disease-resistant varieties generally have fewer single-leaf lesions, smaller lesions, and lighter disease severity. Can also be used 70% thiophanate-methyl WP 1000 times; 50% carbendazim WP 500 times; 50% TB wettable powder 800 times or 75% WP 700-800 The liquid is sprayed before and after the sowing period of the soybean, and the spraying is generally twice. S. sclerotiorum mainly infects stems. The onset began in late July. Helianthus annuus soybeans, heavy soybeans, low-lying soybeans, and high-density, high-yield soybeans have been weighed heavily. In the end of July and August, the incidence of heavy rainfall was heavy. The seeds can be removed by selecting the nucleus, rotating for crop rotation, and removing the diseased plants to burn off. For control, 35% Dovecote seed coating can be used for seed dressing at 1.5% of the seed amount, or 40% sclerotia net, 50% carbendazim, and 40% seed dressing for 0.3% to 0.4% of the seed amount. When the incidence of local patches reaches more than 15%, 70% thiophanate-methyl or 65% Zeoxin 400 to 600 times liquid, 72% Kelu wettable powder 1000 times, 40% Carbendazim The agent 500 ~ 1000 times liquid, every 7 days and then spray a better control effect. The control of alfalfa can be coated with seed coating agents, and seed coating agents against the underground pests are selected. Phoxim granules can also be used and applied to the soil together with the fertilizer. Soya bean borer mainly appeared in the end of July to early August. It was found that there were a large number of adults in the field and began to control. Dichlorvos can be used to control adult worms, ie cut corn stalks or sorghum stalks into 20 to 40 centimeters in length. After a period of peeling, the other end is kept as it is. The squid will be made into 80% dichlorvos emulsifiable concentrate to make a drug stick. One end of the medicine is inserted on the soybean ridge, and every 4~6 ridges are inserted one by one, every 4 meters or so. Insecticides can also be sprayed.
