Soybean grain size, vegetative growth has basically stopped, reproductive growth is in an exuberant period, plant organic nutrients to a large number of grain operation, grain gradually expanded, is the largest period of soybean dry matter accumulation.
Soybean grain size requires more phosphorus and potassium fertilizers. During this period, these nutrients are taken from the soil below the tillage layer by the roots, and the nutrient conversion and release capacity of the soil below the tillage layer is weak, which leads to soybean nutrient. The demand does not harmonize with the soil fertility. It is prone to malnutrition and premature aging, which has become a major factor limiting the high yield of soybeans.
Soybean grain fertilizer spraying fertilizer at root stage can relieve the contradiction between soybean requirement fertilizer and fertilizer supply, accelerate the accumulation, transformation and transportation of assimilation products. In this period, the root-spraying fertilizer can promote the translocation of nutrients to the grains, reduce and avoid the grains, promote full grain, increase grain weight, and increase yield.
Soybean flowering begins and the absorption of phosphorus increases until it reaches maturity. Potassium can mainly regulate the physiology and biochemical function of plants, and cooperate with phosphorus in the late growth stage of soybean, accelerate the conversion of the material into a storage form, and promote grain swelling. Therefore, 0.5% urea + 0.4% potassium dihydrogen phosphate + 0.1% borax + 0.1% brown sugar mixed solution was sprayed outside the root of the soybean kernels, spraying once every 7 days to reduce pods, increase grain weight, and increase yield. There is a significant effect. According to tests, even spraying 2-3 times can generally increase production by 12-15%.

Shiitake is closely related to Ganoderma. Shiitake is Japan's largest agricultural export product, and it is now the most popular and cultivated exotic mushroom in the world. In China, the history of shiitake mushrooms can be traced back to the Ming Dynasty (1368-1644 AD). Shiitake is used not only as a food, but also as a medicine for treating upper respiratory tract diseases, poor blood circulation, liver diseases, fatigue and weakness, as well as promoting Qi or vital energy. It is also thought to prevent premature aging.
