Trace elements needed for soybean growth and application methods
Normal soybean growth requires some trace elements, among which the more important ones are molybdenum, boron, zinc, manganese, etc. Molybdenum is a component of soybean root nodule nitrogenase and an indispensable component for the normal life activities of nitrogen-fixing bacteria. Boron is also very important in soybean life activities. Soybeans deficient in boron have poor root development and poor nodule formation, losing their nitrogen-fixing ability. Therefore, attention must also be paid to trace elements. Can the trace elements needed by soybeans be satisfied from the soil? This depends on the abundance or deficiency of trace elements in the soil and environmental conditions. For example, in low-lying or poorly drained

What are the technical elements of artificial cultivation of Gastrodia elata (tianma)?
(1) Change from wild to domestic planting. (2) Adopt single-layer and double-layer cultivation, and further develop to three-layer cultivation. (3) Use the fungal-wood companion planting method to add covering wood to both the upper and lower layers, so that the fungal threads grow both upward and downward, and the fungal threads in the middle layer interweave into a network from top to bottom, which is more conducive to the growth of Gastrodia elata. (4) When using large tree branches and knots as fungal wood, pay attention to using small branches and knots, which not only saves wood but also makes it convenient to use local materials in plain areas, making full use of raw materials. (5) Use wooden box cultivation and brick pool cultivation

Functions of Essential Nutrient Elements in Garlic and Detailed Explanation of Deficiency Symptoms
Garlic prefers loose soil rich in humus, has strong adaptability to soil pH, and grows well under slightly alkaline conditions. Among the different growth stages of garlic, the demand for nitrogen is the highest, followed by potassium, calcium, phosphorus, and magnesium. For every 1000 kg of fresh garlic produced, it needs to absorb 4.5-5.0 kg of nitrogen, 1.1-1.3 kg of phosphorus, and 4.1-4.7 kg of potassium, with a ratio of about 1:0.25-0.9. The root system of garlic is a string-like fleshy root system, mainly distributed within the 5-25 cm plow layer, and it belongs to shallow-rooted vegetables.
