Higher nitrogen application level is beneficial to the increase of protein content(wholesale nursery pots). Phosphate fertilizer has a greater effect on soybean fat, but no matter which kind of fertilizer, there is an optimal application rate, and it is The combined effect of fertilizers is not a single role of a certain fertilizer(50 cell plant trays bulk), so it is necessary to balance fertilization, time, place, and production purposes (production of high oil varieties or high protein varieties) fertilization.
Within a certain amount range(72 cell seed trays wholesale), the nitrogen accumulation of soybean plants and soybean grain yield increased with the increase of nitrogen application rate. It is also beneficial to increase the symbiotic nitrogen fixation rate and increase the utilization of soil nitrogen and other elements(104 cell plug trays supplier). The effect of nitrogen fertilizer on the nutritional quality of soybeans was different due to soil fertility, fertilization ratio and soybean varieties.(cheap large hydroponics trays wholesale price online)
Phosphate rock powder on acidic or slightly acidic soil is a cost-effective measure to increase soybean fertilization soil(50 cell seed trays wholesale). In recent years, potassium deficiency has often occurred in various parts of China. Spring soybeans in the northeast, soybeans in the Huanghuai region, and phosphate fertilizers in the spring(105 cell seed trays wholesale), summer and autumn in the south have good yield-increasing effects, which can increase production by 10%-50%.
(cheap large hydroponics trays wholesale price online)Potassium application can prevent the appearance of yellowing symptoms, and potassium application that has symptoms of yellow flowers can be corrected(plastic nursery pots manufacturers). Nitrogen fertilizer has certain effects on the fatty acid and amino acid composition of soybean kernels, thus affecting the quality of soybean. In major producing areas of the country, especially the Huanghuai area(sureroot plug trays bulk), The increase in phosphorus application in soybeans is most pronounced.
Soybean growth period can be divided into pre-fertilization, mid-term and post-production(cell trays). According to the test results in the northeast and Huanghuai areas, phosphorus application increased nodulation and promoted symbiotic nitrogen fixation. Phosphate fertilizer could increase nitrogen fixation by 33 kg per hectare(seed planting trays wholesale). Therefore, in soybean production, nitrogen should be applied according to the response characteristics of soybean varieties to nitrogen fertilizer.(cheap large hydroponics trays wholesale price online)
Nitrogen fertilizer has a significant effect on soybean protein(black plastic nursery pots). The results of pot experiment and field experiment showed that the leaves of potassium fertilizer increased significantly, the color of leaves turned green, the functional period was prolonged, and the dry weight and grain weight of plants increased significantly(18 cell plug trays supplier). Potassium application increases the fat content of soybean seeds, reduces protein content, and increases palmitic acid content.
Phosphorus fertilizer test results in Henan and Hubei can increase the protein content of soybean grains(plastic nursery pots wholesale). The symptoms of potassium deficiency in soybeans showed different characteristics at different growth stages, mainly due to different parts of yellow leaves and different color changes, but the leaves were small and the plants were weak(20 cell plug trays supplier). Generally, the yield increase effect of nitrogen fertilizer is closely related to soil fertility level and soybean variety characteristics.
(cheap large hydroponics trays wholesale price online)Potassium plays an important role in the growth of soybeans(plastic nursery pots). Potassium fertilizer in potassium-deficient soil promoted root development and nodulation, increased symbiotic nitrogen fixation rate, and enhanced nitrogen nutrition during flowering and pod-forming period(40 cell plug trays supplier). Potassium application of potassium in all parts of the country, especially the combined application of potassium, phosphorus and nitrogen, has a significant increase in yield.
