How to Grow Soybeans for High Yield? Detailed Explanation of Key Cultivation Techniques
1. Crop rotation selection: Choose level, low-lying land with good drainage, where the previous crop received adequate fertilizer and the soil is fertile - wheat, corn, potatoes, and melon or vegetable plots are best. Do not plant after continuous cropping or after sunflowers; compared with proper rotation, yield will decrease by 21.3%. 2. Land preparation and fertilization: Autumn plowing, land preparation, and fertilization are best, as this helps preserve soil moisture and freeze insect eggs to death. If preparing land in spring, it must be done during the thawing period. When preparing the land, according to soil fertility, generally apply more than 2 cubic meters of high-quality farmyard manure per mu, 10Kg of diammonium phosphate, and 5Kg of potassium sulfate, mix evenly, and apply before ridging as base fertilizer. 3. Seed dressing with chemicals: To control underground pests, you can use

Detailed Explanation of Sprinkler Irrigation Techniques for Soybeans During the Pod-Filling Stage
When soybeans enter the pod-filling and maturation stages, they still need some water and nutrients to promote material accumulation and maturation, improve the seed-setting rate, and increase yield. For many years, when soybeans enter the pod-filling stage, conditions are generally very dry, which adversely affects the pod filling and maturation of the top and upper pods. In response, some farmers use sprinkler irrigation with well water during this period to alleviate the drought. Production practice has proven that soybeans sprinkler-irrigated with pumped water during the pod-filling stage not only fail to promote maturation after one week, but instead cause some branches and plants to turn yellow prematurely or even die, thereby reducing yield. The reason is that soybeans

What causes soybeans to produce many flowers but few pods?
At present, many farmers growing soybeans have found that in some plots the soybean plants produce many flowers but few pods. The reasons can be found through a "five checks." First, check the soil structure and analyze whether the soil pH value is too high, and whether the field has been repeatedly cropped with soybeans or is a continuous cropping field; second, check the fertilizer content and analyze whether the ratio of nitrogen, phosphorus and potassium in the applied chemical fertilizer is reasonable; third, check the planting structure and analyze whether the planting density is reasonable; fourth, check the plant roots and analyze whether pests and diseases have occurred on the roots; fifth, check the soil moisture and analyze whether the moisture content is too high or too low, since both excessive drought and excessive waterlogging will affect the pod-setting rate. Only by carefully

Detailed Explanation of Key Management Techniques for Soybeans During the Flowering and Podding Stage
During the flowering and podding stage, soybeans require thick, sturdy stems and dark green, thick leaves free of spots. Field management mainly focuses on preventing premature aging, controlling excessive vegetative growth, preserving flowers and increasing pods, and preventing shedding. 1. Skillful application of flower fertilizer. The flowering and podding stage is the period when soybeans absorb the most nutrients, and skillful application of flower fertilizer can generally increase yield by more than 15%. At the early flowering stage of soybeans, generally 5-10 kg of urea is applied per 667 sq m as a topdressing; for poorly growing plants, more should be applied, while for robust and luxuriant plants, less or no topdressing should be applied. In conjunction with nitrogen fertilizer application at the flowering stage, phosphorus, potassium, and trace element fertilizers such as boron and molybdenum should be sprayed on the leaves. Generally, 2 sprays are applied, each time per

How to Grow High-Yield Soybeans? A Detailed Guide to the "Four Changes and One Addition" Cultivation Technique
Traditional drill sowing of soybeans results in narrow rows and overcrowding, and along with various other factors, yields have long hovered around 100-150 kg. Through years of experimental research, we have developed a new approach that can increase soybean yields by more than 40%, namely the "Four Changes and One Addition" technique. The usual measures for increasing soybean yields include, besides selecting new high-quality, high-yield varieties, paying attention to crop rotation. According to experiments, after years of continuous cropping, soybeans show slow growth, short plants, yellowing lower leaves, early leaf drop, and few pods with small seeds. Experiments

Why can't soybeans be planted in continuous cropping?
Soybeans are commonly known as yellow beans. Farmers have a traditional habit of planting soybeans this year and continuing to plant them next year, which results in stunted growth, shortness, yellowing leaves, susceptibility to pests and diseases, fewer pods and small seeds, and significantly reduced yield in continuously cropped soybeans. According to surveys, under normal circumstances, continuous cropping of soybeans reduces yield by 20%-30% or more. The main reasons for the yield reduction: pests and diseases are prone to occur. Several diseases parasitic on soybeans, such as bacterial spot disease, black spot disease, damping-off, and yellow wilt, have suitable conditions for occurrence in continuously cropped soybean soil and will inevitably occur in large numbers

Why soybeans should not be grown in continuous or alternate-year cropping
Soybean continuous and alternate-year cropping control techniques can reduce the impact on yield. Impact on soybean yield. Different environments have different effects on soybean yield. ①Continuous cropping is severe, alternate-year cropping is mild; ②severe in the west and southwest, mild in the north and east; ③severe on poor land, mild on fertile land; ④severe on ridge slopes, mild in low-lying wet areas; ⑤severe in dry years, mild in rainy years; ⑥severe with no or little fertilizer, mild with more fertilizer; ⑦severe with original-ridge sowing, mild with plowed new ridges; ⑧severe with many soil-borne diseases and pests, mild with few diseases and pests; ⑨severe on long-cultivated land, mild on newly reclaimed land; ⑩severe under drought, mild with irrigation. The four eastern leagues of the Inner Mongolia Autonomous Region are each similar to their adjacent provinces, among which the Hulunbuir League area is similar to the northern part of Heilongjiang Province, and the continuous cropping phenomenon is also very severe. Today I want to discuss three issues: first, the impact of continuous and alternate-year soybean cropping on soybean yield and quality; second, the reasons for continuous and alternate-year soybean cropping; third, control techniques.

High-yield and high-efficiency cultivation technique for interplanting onions with grain and soybeans
Interplanting onions with grain and soybeans is an effective way to achieve two harvests from one plot and raise the cropping index. It is designed, on the premise of ensuring grain production, to develop off-season vegetable production, increase returns, and achieve high yield and high efficiency. Its main cultivation points are: 1. Select improved varieties: for corn, Haidan No. 2 can be used; for soybeans, Liaodou 10 can be used; for onions, Xiongyuan No. 1. 2. Grow strong seedlings: onions are raised in autumn seedlings. Generally from August 15 to August 22. Prepare beds and apply 5000 kg of decomposed farmyard manure per mu, and diammonium phosphate
