Soybeans are warm and hi-light crops with simple management and low investment. However, the planting is too late, the light is insufficient, the accumulated temperature is not enough; the fertilizer is not paid attention to; the density is too dense or too thin; the herbicide is improperly used to cause phytotoxicity. It is often impossible to get good yields. In response to these problems, we must focus on the following seeding techniques. First, the variety selection. It must be in the early maturity, good quality, uniform grain and high yield. According to your own situation, you can choose the following varieties, Zhonghuang 25, Zhonghuang 35, Zhonghuang 39, Kidney Bean 12, Kidney Bean 17, Kidney Bean 19, Kidney Bean No. 5, Kefeng 14 and so on. Second, apply a good base fertilizer. To apply more phosphorus and potassium fertilizer, less nitrogen fertilizer. In combination with smashing or using a fertilizer planter, apply 50 yuan of soybean special compound fertilizer or ternary compound fertilizer per acre. Third, improve the quality of planting. Early harvesting of wheat after harvest can effectively increase yield and quality. Generally no later than June 25th, harvesting wheat can be used to keep low sorghum, sown and then irrigated. After conditions are available, the wheat can be harvested and the land is removed. The rotary tillage, fertilization, sowing and refining machines are selected to effectively ensure the quality of the sowing. Reasonable close planting guarantees the whole seedling, the principle is that the sowing is early, the ground is strong, the forked beans and the high-yield field are thin. Generally, the amount of seed used is 10-12 kg, and it is sown by mechanical precision. One foot three to one and a half feet, the plant spacing is two inches and a half to three. The depth of the sowing should be even, and the depth should be half an inch to one inch, especially the depth of watering after sowing. Soybean seedlings should be checked in time after emergence, and the seedlings should be replanted in time for the lack of seedlings and ridges. After the seedlings, the seedlings should be fixed and the seedlings should be evenly distributed. Fourth, it is scientific weeding. The first is to broadcast the ground before the seedlings, smashing and sowing, spraying immediately after sowing; spraying the meditation water after 2-3 days to complete the spraying. The floor is sealed with 50% acetochlor, propisochlor, or metolachlor. The two sprayers are evenly sprayed with water. The second is the weeding after the seedlings. In the 2-3 leaf-to-leaf stage of soybeans, the weeds are as small as possible, generally not exceeding 4 leaves. Choose quizalofop, fluvofloxacin, and high-efficiency flupirtine. Acre two sprayer water spray evenly. The post-emergence herbicide must master the dosage, and the back-and-back spray should minimize the bean sprouts.

Antibiotic:
A drug used to treat bacterial infections. Antibiotics have no effect on viral
infections. Originally, an antibiotic was a substance produced by one
microorganism that selectively inhibits the growth of another. Synthetic
antibiotics, usually chemically related to natural antibiotics, have since been
produced that accomplish comparable tasks.
Antimicrobial:
A drug used to treat a microbial infection(antibiotic drugs).
"Antimicrobial"
is a general term that refers to a group of drugs that includes antibiotics,
antifungals, antiprotozoals, and antivirals.
