Daejeon soybean seed wholesale price of soybean seed base in Shandong Academy of Agricultural Sciences

 1, planting density. Soybean planting density to be due to land, due to the region, because species may be. Usually the same species cold area to dilute, warm area should be close; Xiaolaowa cold block to dilute, Gaozao warm land should close. In determining the number of trees per acre premise should be maintained to promote uniform planting, do not advocate two plants or flowers soybean planting. The Institute for Promotion of species density planting techniques reference data, after the introduction of each demonstration households, according to local conditions to develop a viable number of trees planted to provide to farmers when the farmers then planted. Soybean cultivation promote horizontal seed, spaced 30-40 centimeters around the cultivation of their own based on the actual test area, acres of seedling increase 30-50% (mean unbranched soybeans). Leading be good later, according to the number of acres of seedling Jurassic determine spacing. Siping flat seeding, an increase of over 30%. When selecting horizontal seed varieties, we chose a grade before ripening varieties, local varieties do not Introduced full growth period. 2. Alternate Cropping. Alternate Cropping is an important factor affecting soybean yield. Mainly because of continuous soybeans pests increased, mainly soybean nematodes, grubs, cutworms and other pests. Disease mainly soybean uptake of phosphorus, potassium, molybdenum, boron and other elements lacking, resulting in lower body resistance to disease. If you increase the anti-insect pests, increasing phosphorus, potassium and other elements, you will get good results, try soybeans and other crop rotation, rotation of 3--5 years as well. Huancha not really change should increase the fertility aspect of pest control measures. 3, soil insect control. First, the use of soybean seed coating seed dressing; the second is mixed with phosphorus or potassium fertilizer mix carbofuran, 5 pounds per acre, can effectively control nematodes and other soil pests. 4, soybean fertilization. Saying goes: "wadi floods beans." This shows that the soybean growing need for adequate moisture, but also that it requires fertile land, but too low-lying too waterlogged land also inhibits the growth of soybean. Over the years, people's ideas always soybean planting in thin on the ground, on the mountain, Lara, on the edge of land, covered with a yield of soybean to low unjustly coat. In fact, soybeans are greedy, fed can work, strength work great potential. It comes greedy, in addition to its own has a "fertilizer factory" - rhizobia outside the key to soybean production, potash, adequate facilities should be based on land. How much fertilizer in the end application is appropriate, but also look at land fertilizer on condition, but no matter what plots planted soybeans, soybeans do not need to break the concept of fertilizer less fertilizer. Donkey want to run fast, do not feed should not. The fall of 1999, I Institute expert investigation team to the rest of the survey, farmers generally found inadequate fertilization. In particular, only nitrogen, not phosphorus, potassium, soybean yield up the mountain, should arouse our attention. Some people think that applying more fertilizer will Soybean lodging, that is your reason more nitrogen fertilizer is applied, at least not with a reasonable use of fertilizer. To obtain good yields of soybean, general 1000 m2 10-12 kg urea, diammonium phosphate about 40 pounds, about 40 pounds of potassium. Fertilizer was applied to the above, it is possible to produce 7500 kg of soybean, properly managed, can reach 80 pounds or more. These three, along with the drug control soil pests of fertilizer uniform mixing, one deep application as base fertilizer application. Late leaf is the main fertilizer per acre former multi ammonia liquid fertilizer flowers, flower buttons, drum tablets three times of spraying. Ammonia liquid fertilizer spraying more good, spraying method, refer to "How to apply more soy ammonia liquid fertilizer," a text that can yield more than 15%.
